Do collagen drinks improve acne? (Episode 231 rebroadcast)

Valerie and Perry are traveling so here's a rebroadcast from last year.

On today’s show we answer questions about…

1. What is the PAO and why can’t I find it on makeup?
2. Will natural collagen drinks or tablets improve the appearance of acne scars?
3. Are anti-frizz serums detrimental to hair?
4. What ingredients should you avoid to prevent milia?

And we’ll have some chit chat about beauty science news...
