This sunscreen turned my mom's and my skin yellow. At first it was fine - went in beautifully, wasn't greasy, and had a light, pleasant fragrance. But then we played tennis, perspired a bit, and something in our sweat must have reacted with something in the sunscreen because we both turned yellow! It looked as though someone had drawn on our faces with a highlighter.
Other than that, great sunscreen, but the yellow skin was not a good side effect.

I've tried many La Roche Posay sunscreens (US versions), and the only one I've kept repurchasing is the SPF 15 daily moisturizer with Mexoryl SX. I use Refissa every night, so a higher SPF is a must, especially because I live in a sunny climate. After trying too many brands to count, I came upon Melt-In Suncreen Milk. While it's not perfect, it's better than most. It does get quite greasy after a couple of hours, and it does peel off and ruin makeup, but it's the least greasy, least "peely" broad-spectrum, photo-stable, high SPF sunscreen I've found. I may have given it 4 lippies if not for the strong enthanol (denatured alcohol) scent this emits upon application.
