I’ve gone through so many sunscreens, but this one works the best for my skin type. No white cast, no oily sheen, and my makeup applies like a dream over it.
Megan K. –
I love that this is a chemical sunscreen with zero irritation! Since it’s a chemical formula, there is absolutely no white cast, and it absorbs so well without looking greasy at all.
Sarah M. –
This feels incredibly hydrating! Since it’s a gel type, it goes on super lightweight and absorbs instantly without any sticky feeling. There’s absolutely no white cast, so my makeup sits perfectly on top without pilling. Thanks to the hyaluronic acid, my skin feels plump and moisturized all day. I have sensitive skin, but this hasn’t caused any breakouts at all. It’s the perfect lightweight SPF for summer.
Lauren Miller –
This is an absolute lifesaver for the summer when the UV rays are intense. Even though it’s a gel type, the application is incredibly smooth. I’m so happy with this purchase.

Zero skin irritation and it goes on so smoothly. There’s no artificial fragrance, which I love, and it feels deeply hydrating.

I¡¯ve been using this Hyaluronic Acid Watery Sun Gel for ages. I¡¯ve tried so many other sunscreens, but nothing melts into the skin as cleanly and beautifully as this one. Love it!
Jessica –
My skin is so reactive that most sunscreens cause immediate breakouts, but this is the only one that doesn’t trigger my skin. Plus, it gives my face such a beautiful, subtle glow after applying.

I was worried it might be sticky because it’s a gel formula, but it actually feels incredibly fresh and goes on like silk. Barely any irritation?I’m so satisfied with this.
Chloe Richardson –
I expected it to be translucent since it’s a gel, but it actually comes out white. However, once you blend it in, it completely disappears with zero white cast. It leaves my skin so hydrated and fresh.
TaylorB –
No crazy white cast, and it literally feels like I just applied a refreshing moisturizer. At first, I wondered if it would absorb well, but if you gently pat it in instead of rubbing, it sinks right into the skin beautifully.

I have acne-prone skin, so finding a good sunscreen is always a struggle. I’ve been using this daily, and it keeps my skin perfectly clear without any irritation. Highly recommend!
