Easy to apply and wear -
Style: Acne/Rosacea Prone Skin
This is good stuff! I do not wear makeup, ever. I also have never been a moisturizer fancy soap kind of gal. Not great about putting sunscreen on my face- all products are heavy and not right for me. And along comes this sunscreen and I go for it and now wear it daily!!! So easy to apply, not greasy, not heavy feeling. Rubs invisible easily. This is good stuff. Worthy and it seems to also really work!! I highly recommend it. I am not paid for my reviews. I’m just like you.

Great product
Style: Uneven & Discolored Skin
Not waterproof, but I use this under my makeup everyday. No scent, not super greasy, and goes under makeup well. I love La Roche Posay products. I have noticed a slight improvement on dark spots over a few months, but it's quality ingredients. This is a daily sunscreen, but it's not for a heavy beach day if you're going in the water. It's definitely water soluble which is great for every day wear.
