I feel like I’ve been on the hunt for the HG sunscreen for a while now. For the longest time I would only use mineral sunscreens because chemical ones can be irritating. Well, I’ve slowly dipped my toes into using chemical SPF’s and found my skin can tolerate it pretty well.
Recently, I learned about PPD and how it relates to sunscreen. Basically PPD stands for Persistent Pigment Darkening and is used to value how well a sunscreen protects against UVA rays – the bad ones that cause aging and hyperpigmentation. IE, a “PPD of 10 means that it’ll take around 10 times longer for your skin to tan, compared to if it was unprotected”.
This La Roche Posay (LRP) has a PPD rating of 31! For reference, most North American sunscreens (and even Asian ones) have PPD ratings of less than 16. What. Is. Good. PPD?! F*ck now I’m realizing, this whole time I’ve been using weak UVA sunscreens and that’s probably why its taking me FOREVER to heal my PIH! Could this LRP sunscreen be my gateway drug to my obsession with EU sunscreens?
