What the gurus are saying

Gurus are enthusiastic about this sunscreen's invisible, weightless formula and water resistance, making it a top pick for swimming and active use. The standout appeal is that it layers without heaviness, works under makeup, and controls sebum. The consistent caveat is the higher price point, which reviewers see as justified for specific high-sweat or water-heavy occasions rather than daily wear, though some use it year-round.

"This one by Allies of Skin, hands down the best I have ever, ever tried."
New Viral $13 SUNSCREEN Changes Everything - Geek & Gorgeous Zero Feel SPF 50
"The Allies of Skin One SPF 50 Invisible Sunscreen Gel is a bespoke formula that is unique to this brand. They've come up with their own individual formulation. This is one of the only truly invisible water resistant sunscreens. If I'm going outdoor swimming, which I like to do a lot in summer, I'll be wearing this for that water resistance. This is a slightly higher price point product, so I use this just exclusively when I need it, when I'm in and out of the water. You don't need water resistant sunscreen every day of the year. You need it when you need it. When you're going in and out of the water, that's when I'll reach for a product like this."
MAXIMUM RETINOL RESULTS - Skincare To Use With Retinal, Tretinoin and Retinol
"This is a truly broadspectrum sunscreen and it's the one that I trust my skin with every single day now. As this product is sweat resistant, it's fantastic for keeping you protected all day long if you're out running errands, getting a little sweaty, maybe you're on a jog. This is absolutely perfect and will have you covered. If I'm going in and out of the pool and I want a specifically water-resistant sunscreen, I'll reach for this. This has a sky high protection factor when it comes to those UVA rays alongside that SPF 50, so this is truly broadspectrum. I use this when I'm in and out of the pool and I need something that's water resistant, and for day-to-day wear I'll go for this one, which is more lightweight. Both of these give you that truly broadspectrum coverage."
🏆 SKINCARE AWARDS 2025 - Worlds Best Skincare 2025
"This is their One SPF 50 Invisible Sunscreen Gel. I love this because it kind of does what it says in the name. It's truly invisible. You put this on the skin and it just disappears without a trace. But it leaves behind that proven SPF 50 and a high level of UVA protection, too. It's like you're not actually wearing anything. It feels invisible. You just don't know it's on the skin, and that is the mark of a good sunscreen. You can put makeup on top of it if you want to and it doesn't budge or peel. It's just a real great all-rounder."
#1 SUNSCREEN 2025 - Best Sunscreens For Anti Aging
"This is the only lightweight, truly invisible, water resistant sunscreen I've ever found. All the others are heavy. They weigh you down. They're more likely to break you out. I want a product that is truly invisible. This is an entirely clear gel and that just works. This is water resistant for 80 minutes, which is more than enough for me to get that swim out of the way. Because this comes with a slightly higher price point, I will save that for the days where I need that water resistance. But I definitely think getting a water resistant sunscreen in your skincare collection is a must for when you need it. And this is one of the best, lightest weight ones I have ever found. And I absolutely love it."
Top 10 SUNSCREENS 2025 - Best Sunscreens For Anti Aging
"This is the best water resistant sunscreen you will ever ever try. It is truly invisible. In fact it's an invisible gel and it just feels beautiful on the skin. Water resistant up to 80 minutes which I love. And most water resistant sunscreens are a little heavy because of the technology you need to make it water resistant. Not with this. It is truly invisible. It is impossibly lightweight and it feels gorgeous. So if you're somebody that's in and out the pool maybe you're looking for that water resistance from your sunscreen, I think this is amazing. If you're looking for an invisible water resistant sunscreen it doesn't get better than this. I absolutely love it."

☀️ My Summer Must-Haves ☀️
"It is called the One, it's an SPF 50 invisible sunscreen gel and it is amazing. It is completely clear, it soaks in beautifully and is completely weightless. Plus it is perfection under your makeup, it's almost like a primer. The best thing about this is it has a technology that allows you to apply it over and over and over again without it feeling heavy. In my opinion this is what sunscreen should be. It actually also helps control sebum production, so for those of you with oily skin or in particularly hot climates this is going to be a big bonus."
✨ My Beauty Empties: Skin, Hair & Body Care | Will I Repurchase?
"Allies of Skin One SPF 50 Invisible Sunscreen Gel is a fantastic sunscreen. It's clear, it's lightweight, and it's perfect for reapplication. You can put it on over and over and over again without it getting heavy or upsetting your skin. I've gone through so many tubes of this. The only reason it's not in my top tier is because it's pricey and I don't need heavy coverage in the winter, so I won't replace this until spring or summer."
