Tea with MD.

"I am actually obsessed with it because it reminds me a lot of another really awesome and rich thick moisturizer for winter but without the hefty price tag. I also like that there's a lot of science behind it. This contains the 3.5% patented BL3 barrier lipid complex, which contains biomimetic lipids meaning ceramides, cholesterol, and fatty acids in the optimized golden ratio that helps your skin barrier stay really strong and hydrated. It also has vitamin B9 folic acid and vitamin E and signal peptides for skin cell regeneration, wound healing, and repair of cells. BL3 was found to improve barrier contents of ceramides and lipids as well as natural moisturizing factors and aquaporin three levels in the skin. Aquaporins are channels in your cell membrane that help facilitate water entry and movement in and out of cells, so it helps you maintain more hydrated skin and a better and more functional skin barrier. I really like the texture of this. It goes on really thick."

"The SkinFix Barrier+ Triple Lipid + Peptide Cream is packed with ceramides, peptides, and humectants like hyaluronic acid and glycerin. It also has red algae for extra help with locking in moisture. I really love its rich, buttery texture. It feels super nourishing on my skin. It is often spoken of as a dupe for the Skin Sudicles triple lipid restore."

"It is pretty thick. There's no smell so this is not likely to cause allergic reactions if you're sensitive to fragrance. This is definitely a very rich and extremely hydrating moisturizer for fall and winter, especially great if you have eczema prone skin or dry skin. I've been a fan of SkinFix for many years across many different product lines and so this one is no different. It's really, really nourishing and hydrating. It doesn't exactly evaporate quickly, which I think is good. You don't want a moisturizer that just absorbs in after a few seconds, so I think this will really do a good job of keeping your skin moisturized all night, even with your heater blaring."

"It has ceramides and anti-inflammatory properties in the form of aloe. I love how thick it is, it's really luxurious feeling cream. I think this is a wonderful one for Accutane skin because it will really deeply hydrate your skin and there's a whole host of these other benefits as well."

"Bare Bones vitamin C serum that basically contains THD ascorbate and a ton of different types of ceramides. Ceramides you can think of as the glue that holds your skin cells, the bricks, together, so it helps your skin perform its main function of being a tight impermeable barrier. It helps with skin barrier function but it also helps with your skin holding on to and retaining water by making sure that you don't get that transepidermal water loss. The Vanicream one is a great option for those of you who want an affordable Bare Bones THD ascorbate based vitamin C that gets the job done without breaking the bank."

"The Vanicream Vitamin C Serum is a really great affordable option. It's THD ascorbate based and goes on like a lightweight serum so it's hydrating enough that I don't have to use an additional serum or moisturizer in the morning."

"The Peter Thomas Roth Potent-C Power Serum is 20% vitamin C in the form of THD ascorbate, 3% vitamin E, and 2% ferulic acid. I really like because it comes out like a hydrating serum. I can just use this in place of a moisturizer and it offers absolutely zero irritation. I love THD ascorbate as opposed to L-ascorbic acid because my sensitive skin just loves this stuff and I can use it every day and not have any issues. You can see how silky and lightweight this is, it's perfect for layering, and it's just a really cosmetically elegant formula that causes zero irritation or stinging."

"The Peter Thomas Roth Potent-C Power Serum is THD ascorbate based and also a serum, and it's so good. I love it."

"As a serum it's almost like a lightweight cream. I really like this texture especially for fall and winter when my skin is dry, especially during pregnancy my skin is super dry, and it forms a hydrating base to the point where I don't usually need to use moisturizer afterwards. I've been using this personally as my vitamin C during the winter because it's very hydrating and very moisturizing."

"This is from Peter Thomas Roth and it's the Potent-C Power Serum. This has 20% of THD ascorbate which is my personal favorite type of vitamin C. It's lipid soluble, it's very stabilized, it's less irritating for my sensitive skin than L ascorbic acid which is in a lot of other vitamin C preparations. It also has 3% vitamin E antioxidant and 2% ferulic acid. I like it because it comes out as a serum as opposed to like a liquid or an oil which a lot of other vitamin C's come out as. It's very hydrating, it's not irritating at all, and I've been really liking it as a base. Vitamin C has a whole host of benefits, it helps to brighten, neutralize free radical damage from the sun. This has been a really cool new product that I've been liking."

"This is an absolute Holy Grail product for me and probably one of my top three products of all time that I use every single day. This has THD ascorbate vitamin E but also 17 other antioxidants. I really think of this as more than just a vitamin C because it really takes kind of a holistic approach to treating your skin. In addition to vitamin C and E, it also has this patented antioxidant called LL-PQQ which helps your body fight free radical production as well as reactive oxidative species from the sun. It also has plankton extract which contains an enzyme that helps to repair existing DNA damage, ergothionine which is an antioxidant, babol for calming soothing effects, niacinamide which is another antioxidant as well as a brightener, licorice extract which is a brightener for dark spots, and tri-floro acetal tripeptide 2 which is a peptide that helps to improve the appearance of skin elasticity and firmness. So it really is like a vitamin C plus product. This definitely comes with a heftier price tag."

"The skinbetter science Alto Advanced Defense and Repair Serum has THD ascorbate, which is a very nonirritating lipid soluble form of vitamin C and this is my personal favorite. It goes on like a lightweight serum so it's hydrating enough that I don't have to use an additional serum or moisturizer in the morning."

"I featured the La Roche-Posay Toleriane Hydrating Gentle Cleanser in my winter skincare video. And spoiler alert, I'm still using it. It's milky, creamy, non-foaming, fragrance-free, and packed with niacinamide, ceramides, and panthenol to support hydration and that healthy skin barrier."

"The other cleanser that I've been reaching for a lot is the La Roche-Posay Toleriane hydrating cleanser and this is made for sensitive skin. This one contains ceramide 3 as well as LRP Prebiotic thermal water which has these soothing antioxidant hydrating properties. It also has glycerin which is a nice humectant and niacinamide which is another antioxidant and can also help brighten. I've been using this one for a really long time as well. It's great for sensitive skin. It never triggers any of my rosacea or my redness. In fact it helps to calm it down and it never causes any stinging or burning."

"I love using this for Accutane patients, acne patients, and rosacea patients, as well as anyone who has a damaged skin barrier from using maybe too many actives. This one contains ceramides, niacinamide, which is an antioxidant and can help with brightening some dark acne marks, and it also has the La Roche-Posay Prebiotic Thermal Water. It comes out like a moisturizing gel cream cleanser. I really like the texture, and whenever my skin is really sensitive or irritated, this is my go-to."

"This is the Elemis Pro-Collagen Cleansing Balm, the original, so this is the yellow one. I love it because it is so luxurious with a wonderful fragrance. This contains starflower oil, elderberry oil, wheat germ, and oat oils. This is your first step in the double cleansing method -- on days when I wear a lot of makeup, foundation, sticky things like mascara, I will always do a double cleanse: first you use an oil-based cleanser and follow that up with a water-based cleanser, and doing this method will really help to remove all of the sweat, dirt, grime, makeup, oils, all the things that collect on your face as you go about your day. This one starts off as a balm, and then you put it on your face and as it warms, as it dissolves, it dissolves into this really rich, luxe oil, and then after that when you put water on it, it becomes kind of like this milky solution. I really like this one because it is a wonderful first step and a wonderful introduction to my nighttime skincare routine. It also does a really good job of not over-stripping my skin -- I feel like some cleansers leave your skin feeling really tight and dry, which is not what you want. This one really leaves my skin cleansed but also feeling really hydrated and prepared for that second cleanse. I've used it all up -- this one is an empty."

"I had a full face of makeup on like foundation, lots of eye shadow, eyelash glue, the whole thing, and at the end of the day it really felt so good to go in with my ELEMIS Pro Collagen Cleansing Balm, melt it into my hands using the warmth of my hands, and then kind of massage it all over my skin and it just melts into my skin. What I love about this product is of course it does a good job of removing my makeup, dirt, grime, sunscreen debris, whatever has collected on my face from the day, but it also leaves my skin feeling really, really soft and hydrated and it feels very luxurious. There is a smell to it, so if you are sensitive to smells this may not be the product for you, but I personally really like this scent. Ingredients-wise, this balm contains brown algae called Pavina havanika found off the coast of the Mediterranean, which helps support hydration in the skin, Elderberry oil, which also helps with hydration and with taking off your makeup, and Starflower oil, which contains high concentrations of gamma linoleic acid, which is important to your skin health and keeping it supple and soft. This ELEMIS Pro Collagen Cleansing Balm is a pricey product at 68 dollars, but it's currently 20 percent off as part of the anniversary sale, so this would be a splurge item or a good item to buy as a gift."

"For cleanser I do recommend the CeraVe Hydrating Cleanser. I've recommended this many times before and I actually use this myself every night. It is a very, very, very gentle as well as hydrating formula. It contains ceramides, which is the main stay of CeraVe's developments and products, and it's just very good for sensitive skin, oily skin, combination skin, acne skin."

"I brought my CeraVe Hydrating Cleanser."

"The CeraVe Hydrating Cleanser has three types of ceramides and hyaluronic acid and this is just a very gentle cleanser that I've used for a long time. It's affordable as well. I don't believe in spending a lot of money on cleansers because these products are only on your face for a minute or so, and I think your money is better spent on other things with more active ingredients like vitamin C or retinoids."

"For a gentle and hydrating cleanser, I would recommend the CeraVe Hydrating Facial Cleanser. This contains three types of ceramides as well as hyaluronic acid, which is a humectant that helps your skin hold on to and retain moisture. It's also very affordable, it's very gentle, it comes in a large size, and I use this myself actually as my regular nighttime cleanser."

"This product is a lactic acid based exfoliant so it's a chemical exfoliant it also has licorice root which is meant for brightening it has aloe for calming down your skin as well as lemongrass for helping with skin radiance. I use this on nights when I'm not using my retinoid. I find that this leaves my skin texture feeling really smooth it helps to unclog my pores and it's just a really nice gentle treatment that gives me all the benefits of an exfoliant without leaving my skin feeling stinging or over exfoliated."

"My personal favorite retinoid-containing product is the skinbetter science AlphaRet Overnight Cream. That's the only retinoid that my really sensitive, rosacea-prone skin can tolerate. It's actually a retinoid conjugated with lactic acid, along with a whole host of other goodies. That's my retinoid of choice for those with sensitive skin."

"SkinBetter Science AlphaRet is a very very gentle retinoid that's conjugated with an AHA and it's the only retinoid that I can tolerate. Knowing specifically that someone has sensitive skin I would recommend that product for them and they can even use that with peel pads."

"I love recommending the Neutrogena Hydro Boost water cream to patients because it's affordable, it's very simple to use, it's no fuss, it's fragrance-free, it's great for those with acne, it's super hydrating without feeling very heavy or greasy on the skin so you can use this morning or night. It contains hyaluronic acid, natural moisturizing factors, tons of amino acids, electrolytes, essential lipids, and ceramides."

"One of the moisturizers that I like to recommend for summertime is the Neutrogena Hydro Boost Water Gel, not the cream or water cream slash gel which is really thick for winter time, but this is the watery gel and this is non-comedogenic, meaning non-pore clogging, and it really goes on like a gel but it provides this great hydration overnight. The main ingredient in the Neutrogena Hydro Boost Water Gel is hyaluronic acid, which is a humectant that will help your skin hold on to and retain moisture, and it's just a really great formula that's also really affordable and you can find it at every drugstore."

"First off is my Holy Grail, the Paula's Choice 2% BHA Liquid Exfoliant. This one is, in my experience, a little bit harsher than the Sunday Riley one, but it's a workhorse. It gets the job done. This will clean out your pores. This is great for acne-prone oily skin. This is a toner, a true toner, so after washing your face you would put this on a cotton pad and apply it to your face, or sometimes I even just apply it to my hands and just smear it all over my face. You would do this on off nights from your retinoids. I usually reach for this one more in spring and summer."

"If you have acne, Paula's Choice 2% Liquid Exfoliant is a great option for you."

"I've been really liking this. It's a Holy Grail 2% Liquid BHA exfoliant, great for use on the nights that you're not using your retinoid. It smells really good, but if you're allergic to fragrance and you don't prefer it then you might not want to use this product."

"Polish Choice 2% BHA Liquid Exfoliant is a holy grail for a reason. With salicylic acid, this is really great to use once or twice a week instead of your retinoid as a powerful exfoliant. Also because it's lipid soluble, it can really go in and clean out all that gunk from your pores."

"This contains that same trio of ceramides, the skin-identical lipid concentrate: ceramide MP, AP, and EOP, so it's very hydrating. It also contains a blend of magnesium, zinc, and copper, an antioxidant complex, vitamin E, another antioxidant, and glycerin, which is a humectant. This reads to me as a very simple, no-frills, no-fuss hydrating serum. The main benefit is that it will help your skin stay hydrated. It doesn't contain any actives that would help with problem areas. There's no vitamin C, azelaic acid, or niacinamide, but I don't think that's the purpose of this product. This is purely a hydration product. If your skin is dry or you need a little boost of hydration for your morning routine, I think this is a fine staple. Would I use it personally? I personally like my hydrating step to also contain some actives that can treat some of my problems. I like multitaskers that not only hydrate but also do other things. But if you're someone who just needs a little bit of hydration, I think this is a fine product for you."

"The only other thing I use when I'm having a flare up of perioral dermatitis is Rhode Glazing Milk. It's super gentle, it helps calm the skin, it doesn't irritate it any further. This is the next morning after I slept with my prescription and my Glazing Milk on -- I kept it super simple -- and you can tell it's a lot less irritated and angry."

"I'm really happy that Tower 28 kind of brought it from the derm world into consumers' everyday routines at home. I like to use it on everything from impaired skin barrier to blemishes to sunburns to body acne, and it does help to repair your skin barrier. I struggle a lot with rosacea and sensitive skin, and this is perfect for reducing that miserable redness and irritation. Great for post-workouts -- I keep this in my gym bag. I spritz it all over after working out and it is just a lifesaver. Hypochlorous acid is actually naturally produced by our body's immune system. It acts as the body's first line of defense against microbes -- so that's not just bacteria, but also fungi, viruses -- leaving your skin feeling a lot more clear, a lot more healthy. This is just a staple."

"The Tower 28 SOS Daily Rescue Facial Spray comes in a travel-friendly size. Hypochlorous acid has been a really buzzy ingredient this year and last year, which is interesting to me because as dermatologists we've used it in treating wounds for a long time. Hypochlorous acid is actually produced by our own body; our immune cells use it to kill bacteria and calm down inflammation, and when put into a spray it can do all of that. We love its antimicrobial and anti-inflammatory properties. You can use this on acne, rosacea, skin that's inflamed, and it really helps to cleanse the skin and neutralize the bacteria. It's also a great hack for workouts: if you're at the gym and don't have time to wash your face afterwards (I do recommend washing your face afterwards), you can always spritz this on when you're sweating and your face is dirty from being in the gym environment or from touching your face after handling gym equipment. This is a good one to throw in your gym bag."

"It's a purified, stabilized molecule that our own immune cells naturally produce to fight off bacteria and soothe irritation. Tower 28 figured out how to bottle that in a safe, skin-friendly formula -- and that's actually not easy to do. Hypochlorous acid is really hard to stabilize and it does not mix well with other actives, which is why this product keeps it simple and pure. That's what makes this an OG. It's clinically effective, super gentle, and easy to use anywhere. I like spritzing it after the gym -- I keep it in my gym bag -- when my skin feels irritated, or when my skin has acne, a rosacea flare-up, or anytime I really need a reset. If your skin's feeling stressed or reactive, this is the one for you."

"This you can think of as your soothing anti-inflammatory antimicrobial toner that you can use pretty much anywhere. It's like a little magic potion. If you had something that was way too strong last week that burned and damaged your skin you can use this to help calm it down. If you have a little patch of itchy irritated skin, whether that's from eczema or from exposure to something that you hadn't tried before, you can try this as well. If you find that you have a little breakout you can use this there as well. I would say this will not replace, however, your dermatologist approved treatments for your skin conditions. For example, this is not going to replace any regimen that I give my patients for eczema or for rosacea or for allergic reactions. This is meant more as an over-the-counter treatment that you can try in addition to and as an adjunct to your dermatologist prescribed and recommended treatments."

"The effects are not permanent and they only last around three to four months, and the more you do them there is a possibility that you can form auto antibodies to the Botox, so it could be possible that you have to switch from Botox to a different type. I started getting Botox back when I was a resident in dermatology at NYU. The injections we gave each other during training were much higher in dosages than I would use on myself now. I was completely frozen after some of those sessions where we were injecting each other. I could not even lift my eyebrows. My brows felt heavy, which is a side effect when you inject too much or too low in the forehead. There were many times when I could not frown at all, like totally frozen, completely immobilized."

"When I inject too much or too low in the forehead, my brows felt heavy, which is a side effect. There were many times when I could not frown at all, totally frozen, completely immobilized. My approach now when I get Botox is that I just want it to look natural. I want people to still be able to move the muscles of their face and be able to have expressions. When patients bring up Botox, they say they don't want to look like those frozen celebrities on TV, but their faces look like that because they're getting too much Botox, too many units. If you're wanting a more natural approach, you can use less Botox and that'll still give you free range of movement. I typically get injected in my forehead area and always get my glabella because I have one deep static wrinkle forming a vertical line there that's getting etched into my skin. I usually get three injections on each side around my crow's feet because I have fine wrinkles over there."

"If you don't have sensitive skin you can purchase Differin over the counter as your retinoid."

"If you're finding that you're starting to get blackheads, whiteheads, and clogged pores, you can use a retinoid and the one that I do recommend is Differin Adapalene Gel 0.1%. That's over the counter and FDA approved to treat acne. These are very very effective for helping normalize skin cell turnover, exfoliate your pores, and help with whiteheads, blackheads, and acne."
