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.
