CosDNA is a website that gives ratings to cosmetics across 3 variables- acne causing, skin irritant and long-term safety. The lower the ratings, the safer is the product.

This really helped in my acne journey. I found that a widely recommended cleanser, touted to be gentle, could actually be worsening my acne.

Though, with skincare, there is no one-fits-all formula but why be unsure?
