It's not the most hydrating sunscreen I've ever used and its texture is reminiscent of a slightly thick serum or an emulsion. It feels good on my skin and did not break me out. No white cast whatsoever, didn't require any blending in, and applied without a tacky finish. One of the sunscreens with the least pilling I've tried, but did very very very slightly pill on the area around the eyes after a long day and some instances of aggressive rubbing. Slightly less glowy and lighter than the BOJ sunscreen.

This reef-safe chemical sunscreen stands out with its naturally glowy and non-greasy finish. It has the texture of a medium moist cream, spreads nicely and dries quickly in just a few minutes, making it easy to apply. It leaves no greasy or sticky residue, and there's no white cast or pilling to worry about. Notably, this sunscreen is highly moisturizing and can effectively replace the need for an additional moisturizer. It's my favourite one during the winter moths. However, I find it bit too moisturizing during the summer. Overall, it is an excellent choice for those looking for moisturizing sun protection without the drawbacks of a heavy or greasy sunscreen.
