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.

Great daily sunscreen with lightweight feel
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I’ve been using this sunscreen daily and I really like it. It feels very light on the skin, absorbs quickly, and does not leave a greasy or heavy feeling. It also works well under makeup and does not cause breakouts. I feel my skin is well protected from the sun and it’s gentle enough for everyday use. I highly recommend it for anyone looking for a reliable sunscreen.
