What the gurus are saying

The peptide technology earns consistent praise for smoothing crepey skin around the elbows, knees, and décolletage by thickening the epidermis and supporting collagen production, which matters most if those areas are your concern. The gel texture applies evenly with minimal white cast for a mineral sunscreen, though one reviewer notes the SPF 30 is lower than many alternatives and the price is steep for what you get. No irritation was reported, but patch testing first is wise given the peptide novelty.

"The One Skin OS-01 Body SPF Broad Spectrum SPF 30 plus is water-resistant up to 80 minutes and has 14% zinc oxide, all mineral, which I like because my skin doesn't like chemical sunscreens, it gets really irritated. It has a true cream-based formulation that could totally replace your body moisturizer for the day, it's moisturizing but also lightweight, and even though you can feel the oils in it, your skin isn't greasy or tacky once it dries down. It leaves little to no cast if you really work it into the skin, and there's no fragrance or sunscreen smell. I have a really hard time finding body sunscreens I want to wear because everything is either too thick or has a gross scent, but I'm actually impressed with this formulation. It's truly 10 out of 10."

THE ULTIMATE ANTI-AGING BODY CARE ROUTINE THAT ACTUALLY WORKS (Best Products for Aging Skin)
"The last product is the OneSkin Body SPF, a broad spectrum SPF 30 plus with a PA+++, water resistant up to 80 minutes, and it also contains that OS-01 senescence blocking peptide. This is a mineral sunscreen with 14% zinc oxide, which is my go to since I only use mineral sunscreens on my face and my body. It doesn't smell like sunscreen, and it keeps the skin really moisturized. A lot of sunscreens, especially body sunscreens, dry out the skin and leave a film that looks white and cast and feels tight, and I hate that, but this one doesn't do that. It has a couple of oils in it so it's very hydrating, and when you first apply it, it feels a little bit like there's an oily [...] texture left behind, but it's not greasy where your [...] clothes stick to your skin, and after it dries down [...] that texture subsides. [...] It literally left no cast on my skin, which is another reason I really love it. [...] This has been my go to body sunscreen this year and I'm really impressed with it. You could totally skip your body moisturizer and just use this, and it provides the same amount of moisture as a body lotion or cream. [...] Halfway through the day your skin doesn't feel dry even if you reapply a couple of times, [...] and it's easy to remove at the end of the day even though it's water resistant. [...] It's fragrance free too. If you're looking for a really good body sunscreen that's fragrance free, wears nicely, and feels good on the skin, I would highly, highly recommend this."

"They even just came out with a body SPF. [...] By having this OS1 proprietary peptide, you're going to increase collagen production, but you're also going to clear out the old senescent cells that are just hanging out. [...] It downregulates those senescent markers and by doing that you improve the epidermal thickness and reprogram your tired cells and actually maybe increasing collagen production in this way as well besides being a cell signaler and telling your fibroblast to make more collagen. So if you have crepey skin, if you're getting crepiness around the elbows, the knees, the décolletage area you want to work on, I think this peptide technology is quite nice and I love having it in my sunscreens. It has a zinc oxide base. It's quite lightweight. [...] This is zinc oxide base, but you are paying for that technology and the price point is higher. I pulled up a recent paper that they did in reconstructed 3D skin models. The OS1 increased epidermal thickness, improved expression of barrier and repair genes."

"This is by OneSkin. This is the OS-01 Body SPF. It's a broad spectrum 30 plus plus, and it's water resistant for 60 minutes. I love this because not only is it protecting my skin from the sun, but it has the same OS-01 peptide that the body lotion does. So it's helping with all the senescent cells. It's protecting from damage that's coming in, but it's also helping to erase the damage that's already there."

"This is my other one, the OS-01. I'm loving this because I feel like not only does it help to kind of even out skin tone, but it's a serum as well. And again, I do the same thing. Little dots [...] first and then you rub it in. And then your product is just going to spread so much more evenly."

"The second sunscreen is a new find for me. It's the body sunscreen by OneSkin. Now, this is only SPF 30 and I just put it on the exposed portions of my body. Usually my hands, kind of my arms in the summer and my décollete sometimes. [...] This is a mineral sunscreen, but I will call out that it does have the octyl salicylate in it, which some are considering a chemical filter, but it's not necessarily recognized as that by the FDA. Another dose of those peptides definitely helps. I love the sunscreen. Have had no irritation from it. Who wouldn't want another dose of the OS1 peptide?"

All-Mineral Sunscreen Review 2025: What Worked, What Flopped & What I’m Using
"They actually also have a One Skin body sunscreen. These are SPF 30, so these would be for days that I'm not going to be out very long, just kind of in and out of the car, just an everyday sunscreen. They have a tinted formula and an untinted formula. I swatched the untinted and it goes on with a fairly significant white cast, but once it dries down, I was really surprised that it just blends right in with a barely noticeable white cast."

"The OneSkin absorbs smoothly without the annoying white cast that store brand leaves [...] on my skin, which is super common with cheaper zinc oxide sunscreens. [...] If OneSkin have managed to make a mineral sunscreen that has less white cast than most other mineral sunscreens, possibly because they are using an SPF booster, that could make this rather expensive sunscreen worth it for some people, but it is only SPF 30, and white cast is usually not that big a problem for those."
