Apad Serum.

"It's a high-dose azelaic acid but in derivative form. It's a water-based serum, unlike the emulsions that I've talked about earlier. So if you like that really lightweight water-based serum, this could be a great option for you. It's just a really nice affordable azelaic acid derivative. And I think that for me, it's nice to have in the market so that people really have choice. Just be aware that you're going to have to invest a little bit longer to see those results, but that's fine. I always say skincare is a marathon, not a sprint. And this is kind of like a foolproof way to use your azelaic acid."

"If you're looking for something that's super gentle, derivative form is a really great option. And my personal favorite is the Geek and Gorgeous A.P.A.D. It'll calm, it'll soothe, and it'll help restore equilibrium in the skin in the long term. You really need to give it a four to six week run in, probably 12 weeks in order to make sure the skin is really primed and set, ready for introducing any higher potency actives. It is a great option though, super inexpensive and one of my personal favorites."

"I've skipped using azelaic acid any day in the past three years. It works wonders on my skin. It calms, it soothes, it hydrates, it reduces acne causing bacteria. It's also great for hyperpigmentation. I'm going with the Geek and Gorgeous A Pad because it's super inexpensive. It's one of my favorite forms of azelaic acid in derivative form, super gentle and it works. It just works and it's so inexpensive. For me it just makes life so simple. I absolutely love it and I'll use like two drops of this and then spread it across the skin. It is so nice. For people that are new to azelaic acid, this derivative form doesn't prickle. It doesn't give any of that tingling sensation. It just gives a really nice calming and soothing, and over time will definitely help minimize acne, hyperpigmentation, and all of that."

"This is the Geek and Gorgeous A Pad, this is an azelleic acid derivative meaning it's super gentle for people that are still a little skeptical about the idea of using azelleic acid with your retinoid. It's even more gentle than azelleic acid in its pure form, so this is a super gentle beginner option or for people that are still a little bit dubious about using azelleic acid and retinoids together. This is a really great option to just slot into your skincare routine to get all those additional benefits."

"If you've got advanced hyperpigmentation, acne scarring, or anything like that, this works so so so well. You get a light tingling from it because after all, it's an azelaic acid. You will get a light tingling, but nothing too extreme. And it's absolutely fine to use alongside retinoids. This is phenomenal. If you actually absolutely want to do azelaic acid on a budget, you cannot go wrong with this. Geek and Gorgeous Apad has never steered me wrong. And because it's a derivative of azelaic acid, it's a little bit more gentle, too. So if you're new, maybe you're scared about the acid in the name and want to go for something gentle, Apad. So, so good."

"I'm using this one because I think hands down, it's the best for minimizing breakouts, preventing acne, and just keeping that whole adult acne situation in check. I would recommend the Geek and Gorgeous Apad every day of the week. It's phenomenal. It's budget friendly. It works for all skin types. I do have a couple of marks from where I've had breakouts that are fading. I find they fade so quick with this one."

"The Geek and Gorgeous A Pad is a 20% azelaic acid derivative. It's super gentle and it's water-based so it just slots seamlessly into your skincare routine and it's super inexpensive. This is phenomenal if you have very acne prone skin because I'd say of all of the formulas, this is the one that's most acne compatible. If you're reaching for your azelaic acid to reduce acne causing bacteria and breakouts, this is probably the one that I would go for. You'll get some amazing results, super easy to incorporate, and you get zero prickling and irritation from it. This is like a sensitive skinned person's dream product. You can go in straight away using it twice a day. You don't need to build up to it because it's that gentle, but it really does pack a punch. I love it."

"The Geek and Gorgeous A Pad is amazing. It's around £12 here in the UK, so around $15. And this is a really great strength of azelaic acid to use alongside your retinoid. You can use them side by side. I would use azelaic acid twice a day, whereas your retinoid you're going to want to use once a day on an evening. That way, it's just going to be so much easier in terms of your retinoid application, minimizing side effects, sensitivity, and irritation."

"This is the Geek and Gorgeous A Pad. I love this as it's an AIC acid derivative so unbelievably gentle. So if you're someone that has skin sensitivity, you're prone to redness irritation, and you want to just have the most gentle form of AIC acid to use alongside your retinoid, this Geek and Gorgeous A Pad wins every time. This is flawless and I cannot recommend it enough."

"My absolute favorite of the Geek and Gorgeous serums is this, the Apad Serum. If you are oily and acne prone, listen up. Apad is the best azelaic acid form you're going to find specifically for oily and acne prone skin. Apad is a derivative of azelaic acid which is clinically proven to be the best form when it comes to minimizing acne-causing bacteria. If you've got adult acne and breakouts, or there's a teen in your life that's going through hormonal acne, get this and use it twice a day, morning and evening, and I promise you within one bottle of it your acne will be so much more improved. It reduces the acne-causing bacteria which is one of the key triggers for those breakouts. For people out there that are looking for an azelaic acid specifically for oily, acne-prone skin, Geek and Gorgeous is the one."

"I really didn't know much about acid until I tried the Geek and Gorgeous Apad Serum, and this is probably going on six or seven years ago now. Within the first week I was blown away as one of the few products that I can say really made a huge difference in my skin very quickly. Acid is amazing, and for me, I think I'm rosacea prone, but my hyperpigmentation and melasma is the biggest issue I have with my skin, and it really helped brighten it up. It helps with redness as well. The formula has panthanol, a skin soothing ingredient; betaine salicylate, which is a mild exfoliant; lanolin, which is skin soothing; licorice root, another soothing and brightening ingredient; neem extract, which is an antioxidant; green tea water, which is an antioxidant; sodium hyaluronate, which is a hydratant; niacinamide for brightening and anti-acne; aloe and beta-glucan, which are both soothing and hydrating ingredients; and centella and centella root extract, which is antioxidant, skin soothing, wound healing, and anti-inflammatory."

"The Geek and Gorgeous Apad Serum, I really love this one. It's super gentle. It's got 20% potassium azelate, which is a derivative of azelaic acid, which is known to be very gentle, so if you haven't used azelaic acid before, it's a nice product to start with. It's great for reducing redness from blemishes, pigmentation, and just plain redness in the skin, and at the same time it's gentle and non-irritating. There's not a ton of other ingredients in here, it's really affordable, and it's just a short ingredient list, so there's not a lot of other ingredients that might irritate your skin. This product when I added it into my skincare routine a few years ago was one of the few products that made an absolutely huge difference in my skin. I highly recommend if you have redness, acne, hyperpigmentation, anything like that, give it a try. It's well worth it and it's very affordable."

"Geek and Gorgeous Apad Serum. Wonderful product. This one uses their human fibroblast conditioned media, they have a trademark on it. It also contains peptides and botanicals, great for anti-aging skin renewal. It's certainly made a huge difference in my fine lines, noticeable difference. But it's $295, which is really expensive. It's on sale from time to time. It's worth buying it on sale. At Dermstore you can subscribe to it and if you subscribe and then change your mind like a month later you don't want to subscribe to it, you can cancel it and they give you an extra discount if you subscribe."

"Geek and Gorgeous Apad uses an AHA acid derivative and I found that made huge differences in my skin just within like 30 days it was amazing. If you have rosacea, hyperpigmentation, melasma, or acne, if you haven't tried AHA acid, check it out, it's amazing. And it's also pretty friendly. A lot of other acids like glycolic acid or lactic acid or salicylic acid can be sensitizing, but AHA acid I've yet to find any issues using it, even on my neck, so it's a wonderful ingredient for so many different things. It's also got niacinamide which is anti-acne and skin brightening, panthenol for soothing and wound healing, a lot of centella in here with centella leaf extract, centella asiatica extract, and centella root extract which are all soothing, antioxidant, help with redness and are anti-inflammatory, and snail secretion filtrate which is antioxidant and an amazing ingredient that contains glycoproteins, enzymes, hyaluronic acid, copper peptides, antimicrobial peptides, and trace elements of copper, zinc, and iron."

"The Apad Serum is one of the few skincare products where I tested it out and I noticed a difference very very quickly, and there's not a lot of brands out there that have done that, but this is one of them."

"Geek and Gorgeous came along with a product called their Apad Serum which contained an AHC acid derivative and I used it and I was just amazed with the benefits from it. It has a nice, serumey texture and it absorbed quickly. I fell in love with AHC acid because it's such an amazing ingredient for so many different things, different types of skin that you would never think would benefit from the same ingredient all kind of come together with this ingredient. So it's absolutely amazing if you haven't tried it, especially if you have rosacea prone skin, redness prone skin, breakout prone skin, oily skin, melasma, hyperpigmentation. This one's got 15% which is a nice sweet spot."

"The Geek and Gorgeous A Pad Serum, which is an azelaic acid derivative. That's the one I used when I noticed the most benefits. It really helped brighten my skin up super fast, really amazingly. It was one of a handful, I'd say there's probably 10 products in my life that have been near instant game changers. That's on that list. The A Pad's a little bit better because it's like 12 bucks."

"The Geek and Gorgeous APAD Serum contains an amazing amount of 50 different peptides as well as several antioxidants such as resveratrol, astaxanthin, ubiquinone, and vitamin C. It's a really good product. Certainly worth checking out."

"Their Apad Serum is the one I've got here, it's 13 bucks, and this is one of a handful of products that were total game changers for my skin. After using it for a couple weeks I could notice my skin was looking much brighter, a lot of the hyperpigmentation melasma was reduced, and my skin just felt better, and it's only 13 bucks."

"This is in the last couple years one of the few game changing products I've truly experienced that have really made my skin better. It really helped with my melasma, redness, sensitivity. The A Pad is an azelaic acid derivative and azelaic acid is the amazing ingredient."

"This product was a total game changer for me. Honestly, I probably didn't really realize I had rosacea until I used this and it really helped. It's got a 20% azelaic acid, which is an ingredient that helps with rosacea, and it's got 6% pure potassium azelate, which is an azelaic acid derivative, and then it's got lanolin. Very affordable, wonderful product, hugely helpful for me. So if you suffer from this, even just redness or things like that, it's very helpful."
