My honest review
Lightweight Protection with No White Cast
I am very satisfied with this sunscreen. The texture is lightweight, it absorbs quickly, and it truly leaves a "no-cast" finish—without that white layer that many sunblocks tend to leave behind. Plus, it feels hydrating thanks to the collagen, so it works beautifully under makeup or on its own for everyday wear.
It offers excellent SPF 50+ PA++++ protection against UVA and UVB rays and leaves no greasy residue. The size is convenient for carrying in a bag or taking along on trips.
After using it for several days, my skin feels protected, soft, and comfortable, even in hot weather. I would definitely buy it again and highly recommend it to anyone looking for a lightweight, hydrating sunscreen with a natural finish.

I'm impressed
I'm delighted with this sunscreen. It has a super light texture that absorbs quickly and does not leave a greasy feeling, which is perfect for everyday use, even under makeup. It fulfills what it promises: it does not leave white residue, something that I value very much, especially in photos or when going out in the sun. In addition, it feels quite moisturizing thanks to collagen and hyaluronic acid, leaving the skin soft and with a natural finish

Love it
This has become my everyday sunscreen and I genuinely love it. It’s lightweight, super hydrating, and doesn’t leave that greasy feeling most sunscreens do. It blends in beautifully and sits perfectly under makeup, which is a must for me.
I also have sensitive skin and this hasn’t caused any irritation or breakouts at all. It just feels smooth, comfortable, and easy to wear daily. One of those products you actually look forward to using.

Don’t buy
All it did was moisturize and it’s super thing and just liquid. I highly doubt this is actually protecting my skin from the sun. Leaves no cast at all though
