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.

Worth it
Style: Uneven & Discolored Skin
This is perfect sunscreen if you have dry and melanated skin. Always glowing afree putting this on annd no white cast ever. There are also no irritants in the sunscreen so applying too much won’t break you out look other sunscreen. The bottle also lasts for about a month 1/2 at a time. Great product

Easy to use, no white residue
Style: Uneven & Discolored Skin
This is one of my favorite skincare products. It is easy to apply, it really goes on smoothly, does not feely greasy or icky, and best of all no white residue. It works well under makeup. At SPF 50, it offers great skin protection and is my go-to on a daily basis.

Amazing sunscreen. Great results
Style: Uneven & Discolored Skin
This was a gift for my mom. La Roche Posay is a great brand and my mom has been using this for years. She always asks for a refill when her bday or Mother’s Day comes around.
