RNR Sun Serum SPF 50.

"I will always, always fall back on the Undefined Beauty RNR Sun Serum. It's a mineral tinted sunscreen that makes your skin look more even dewy and glowy. People ask if I'm wearing makeup when I'm wearing this one, and they now do a few different shades. If you find your skin gets irritated from sunscreens, if you have rosacea like me, and you have to keep always playing around with different sunscreens, this is a really, really nice one to go for."

"It looks like I have really nice skin. It's slightly tinted. When I wear this, people do ask if I'm wearing makeup, but I think because it's just such a nice light, sheer coverage, more people are like, where's your rosacea gone? It's not full coverage in any way, but my skin does just look better because of that tint. It's a mineral sunscreen, so it doesn't sting my eyes in any way. It's just my go-to sunscreen, all year round, all the time."

"The Undefined Beauty RNR Sun Serum is a broad spectrum SPF 50 mineral sunscreen. It has a slight tint that now comes in a few shades, it does not sting my eyes, it does not affect my rosacea at all, and whenever I wear it people ask if I am wearing makeup because it gives a bit of BB style coverage, not full coverage but a nice natural finish."

"Probably my favorite sunscreen of all time, this is a fully mineral tinted sunscreen available in three shades, it's got cica mushroom in it which is very hydrating, and niacinamide, it gives you a very natural looking glow, sometimes people ask if I'm wearing makeup but it's not heavy coverage. I've been using this solidly for about 2 years now, absolutely love it, never going to stop using it."

"The Undefined R.R Sun Serum is possibly one of my favorite sunscreens of not just this year but of all time so far. I've been wearing it for two and a half weeks now with absolutely no issue."

"I've been using this sunscreen for 2 years since it won, unfortunately over the last year it was reformulated because they were having a lot of separating with the formula. So I had to retest and this year it came in fourth. For me it wasn't as good because it was perfect under makeup before. The old formula made my makeup last all day, no settling in wrinkles, no wearing off. The new formula goes on less wet feeling, less oily feeling than the old formula, so some people will actually like it better because it doesn't feel as wet or oily. But the problem is that it also didn't wear as well under makeup. When I first applied the makeup it looked absolutely beautiful, but by the end of the day I could tell that it definitely had changed because my makeup wore off much much faster. I am going to continue to still use this as one of my beach sunscreens because I feel like the finish on this is better than the old one, but it's not something that I reach for anymore on an everyday basis because on most days I do wear some makeup and where it doesn't make my makeup last super long anymore, it's kind of dropped in the rankings."

"The sunscreen I'm going to use today is my Undefined RNR sunscreen, it's an SPF 50. It's 40 minutes water resistant and it has a PA rating of PA plus plus plus which tells me that it's giving me really robust UVA protection. I do like this one a lot though because it is 22 percent zinc so I think it probably does have really good UVA protection as well and UVA are really the rays that cause a lot of the aging on our skin and also causes a lot of the skin cancers."

"As a standalone sunscreen this is just as good as it was before I'm giving it four out of five as a standalone sunscreen but only three out of five for under makeup."

"Another favorite is my Undefined Beauty RNR sunscreen, this is an SPF 50, it's water resistant to 40 minutes. This one is very oil forward and it's really great for people with super dry skin. Some people, if you have more combo skin, you may find it to be just a little bit too oily feeling on your skin, but if you have really dry skin this is amazing, especially in the winter. And I love this one so much. This one is tinted, it does come in three different shades so you can find the shade match for you. It comes in a light, a medium, and a dark, and I wear the medium tint in this. And I love this sunscreen, it's so good."

"I also have my Undefined Beauty RNR sunscreen in there. This one is water resistant to 40 minutes."

"I have a new favorite Holy Grail sunscreen that one is the undefined r r sunscreen this is an SPF 50 PA plus plus plus this has replaced if you can believe it the Alta MD is my daily sunscreen I can't believe it I love this one for so long and love it so much I still use it quite a bit but for the average day this is the one I reach for this is one is much more lightweight and fluid."

"My current favorite sunscreen is the Undefined R R. This is a really lightweight, fluid, liquidy sunscreen with a nice medium light to medium tint that works really well for my skin. I'm actually almost out—I go through so much of this. It contains squalane and some other really nice ingredients, so it's going to be great for people with drier skin. It's not going to dry out your skin, it's going to be really hydrating. I wear this one every day, I wear it under makeup, it doesn't affect the wear of my makeup, and it doesn't settle in my wrinkle lines."

"My Holy Grail sunscreen currently is the undefined R.R. sunscreen. This is a beautiful sunscreen, it's an SPF 50 with a PA plus plus plus rating, which means it's giving you the highest UVA protection. It's also 40 minutes water resistant, and if you have dry skin this is going to be really really hydrating. It's just beautiful under makeup. It's the one that I wear when I test makeup. It's an all-around perfect sunscreen for me. It is tinted and the tint is right for me. It feels like a little bit oily, a little bit, I wouldn't say greasy, just very emollient and very hydrating going on."

"I found this brand called Undefined and their RNR Sun Serum is an SPF 50 with a PA++++ rating, which is the highest UVA rating you can get in a sunscreen. It's really lightweight and fluid with a slight tint that hides the white cast without tinting your skin. It rubs in so quickly and easily, and I've been wearing it under my makeup since I discovered it. It's a really good one and it's a really hydrating sunscreen as well, so if you have skin that's on the drier side, you've got to give this one a try."

"This is a lightweight runny tinted liquid with a lightweight greasy feel that doesn't feel super heavy, tacky, or greasy on my fingers. It doesn't leave any white cast, blends quickly and easily, and isn't overly shiny. After 20 minutes it feels dry and set with a nice finish. Makeup goes on really nicely over this sunscreen and wore really well all day without getting shiny or feeling drying. I love that it feels hydrating, doesn't feel drying, and makes my makeup look really youthful, really natural, and skin-like. This is the winner this year and I have been wearing this non-stop since I found it. It works really well with all my different foundations."

"I found a new sunscreen in my sunscreen testing video this year that I love so much. It is an SPF 50 with a PA plus plus plus rating. It's very lightweight and fluid. It's also tinted and it's very pretty. I've been using that one every day since I finished the EltaMD one up, and it is the Undefined R.R. sunscreen. I've been using that one more than the EltaMD because this is more of a traditional lotion and that's like a really lightweight fluid. The R.R. is forty minutes water resistant as well, and it's a little bit less expensive. They're both great sunscreens."

"Undefined Beauty has a sunscreen that's tinted that I really like I've been raving about for a few years, the RNR Sun Serum. They also recently came out with an organic non-tinted sunscreen that I've been trying out and I really like. It's like nice and amoyan."

"I really love their Sun Serum, it's quite good. I think this is now sold in Ulta too, and it's a really good tinted mineral sunscreen."

"This one is a favorite of mine, the RNR Sun Serum by Undefined Beauty."

"I'm rather enjoying this Undefined Beauty RNR Sun serum, so I'm going to wear it here."

"This is Undefined Beauty's RNR Sun Serum SPF 50, water resistant forty minutes. This has become a favorite of mine, it's a liquid formula, the tint is medium to pale, and it spreads on the skin really nicely. It has a bit of a slippery polymer consistency, but it doesn't have that buttery whipped consistency, it's not greasy, and it would be a great product to apply and then put makeup on over as a makeup base. It has tremella fusiformis extract, which is very hydrating, raspberry seed oil, which is an emollient, and rice bran extract, which has moisturizing properties. This does have niacinamide in it, so if you have issues with niacinamide this would be one to skip, but I really liked it. It's twenty eight dollars for 1.7 ounces, so not inexpensive, but I like the liquid formula, it's easy to spread on the skin with no clumping, no pilling. Right now this is one of the ones I keep going back to time and time again."

"I highly recommend the Undefined Beauty RNR Sun Serum - it's a mineral tinted sunscreen with niacinamide, which is helpful for redness and hyperpigmentation, and tremella, which is mushroom extract for moisture. This looks great on the skin in my opinion. I love it and I'm currently wearing it, though it is pricey."

"This one I have been loving. It is a mineral sunscreen that is tinted and blends onto the skin well, giving the skin a nice hydrated glow without being greasy or shiny. It doesn't peel or roll up off of the skin and it's water resistant so you could rely on this if you're going to be outside for a prolonged period of time. It's mineral so there's no issue with it burning or stinging around the eyes. I'm pretty impressed with the tint because sometimes tinted mineral sunscreens can be too orangey or have almost a terra cotta pot look to them, but this is not that way. It is a peachier brown but it really blends in very sheer on the surface of the skin. Now if you have a deeper skin tone I suspect this likely will still leave a cast and I'm hoping that in the future they come out with more shades. It also has tremella, a mushroom extract that helps with moisture retention, and niacinamide which is a great ingredient that helps calm down redness, is helpful for hyperpigmentation, and helpful for the moisture barrier. This is free of fragrance but it does have a little bit of a scent that smells exactly like the Color Science Unforgettable Face Shield."

"I haven't heard anybody really hyping this up and it is so good. It's a tinted mineral sunscreen that's water resistant and really does blend onto the skin in a sheer fashion without looking casty. It spreads well, it's not greasy, and it gives the skin a nice luminous glow. It's very similar to the Ilia Skin Tint which is $48 for an ounce, but this is much more affordable at $28 for 1.7 ounces. The main limitations are that it only comes in one shade, so it may show up on deeper skin tones, and it does have niacinamide and some botanic extracts that could potentially irritate some people. But I think it gives the skin a very nice glow and is a great value."

"This has so many good ingredients for the skin. It has niacinamide, it has antioxidants like vitamin E, and it also has soothing ingredients like Allantoin, sunflower and rosemary leaf extract, so it's just doing nice things for the skin. It's very lightweight, it absorbs very quickly, it is easy to layer, and it's non-drying. It is gorgeous under makeup. This was one of those I can see this becoming a Holy Grail one that I'm going to reach for over and over again. It's a five out of five. This is fabulous. The only downside is that I have to ship it in from the US. They don't seem to be necessarily selling it here in the EU or on the side of the pond at all, which is a bit of a bummer."

"This is the RNR Sun Serum by Undefined and I just love it. It was a recent discovery for me this year and my sunscreen challenge. It just evens out my skin tone, gives me adequate coverage, just makes me look a little bit better. I do carry a lot of redness in the middle of my face so this just makes things a little bit better. It's also quite moisturizing and it gives a little bit of a glow."

"I did my sunscreen challenge video back in May and I put this in as one of my favorites. I thought that the texture was good and I thought the finish was great and it went on really well. But then it started to degrade and it started to separate so you could see the color sitting separate from the oils and it got disgusting. It also got really hard for me to apply like it got so incredibly runny that it would be running down here before I could get it on my face. Ireland is not freaking hot and this was just sitting in my bathroom in a relatively cool space with not a huge amount of light. I was so disappointed because I started off loving this product and now it's just going into the bin. I couldn't even share this with someone. It's gotten so watery and it's just difficult to use. My little heart was broken because I recommended it to so many people and I know quite a few of you have picked it up. I imported this all the way from the US and I started off liking it and it ended up being a dud."
