La Roche-Posay Mela B3 Dark Spot Serum With Melasyl+Niacinamide 32 ingredients
Haven't noticed any difference in my acne scars so far as all it did was induce purging (has pro-retinol in the ingredients). Been using it for like a month and not noticing any results so far, I've noticed more results after using my Caudalie serum for a week.
i am more than impressed. la roche-posay has truly outdone themselves with melasyl. this serum is an incredible product that quickly and efficiently does its job with minimal irritation. no complaints. i do feel as though it is important to note that when i started using this i had already been using retinol for 2+ months which may have affected my initial reaction to the pro-retinol ingredients Show more
