Hi, I'm Perry and you're listening to The Beauty Brains.

Hello and welcome to the Beauty Brains, a show where real cosmetic chemists answer your beauty product questions and give you an insider's look at the cosmetic

industry. This is episode 407. I'm your host Perry Romanoowski and with me today is Valerie George.

Hello Valerie. Hi Perry. Hey Valerie, we got lots of questions since we were off for like three

weeks because I was traveling and we just

couldn't connect and the questions have been building up so today we are going to cover some ones

that were sent in recently including is the journal of cosmetic dermatology a reliable source for

peptide information how do you know if a product with an active ingredient has enough to be

effective? Does topical estrogen improve the skin? Do at-home microneedling devices work? And do you

need to use hypochloris spray for skin care? And finally, is a salon tangleer different than the ones you can buy at regular

stores. But first, Valerie, it's been a while. Where have you been, Perry? I know you went to France.

I was supposed to go on that trip and baby cosmetic chemist totally ruined everything in a good way.

Sure, sure.

But you were gone forever.

You know, I was gone for 20-something days.

Actually, when I go on trips, I always do a thing called trip notes, where I write down exactly

what I do all day.

Okay.

What time I wake up, you know. My wife hates these trip notes because sometimes I put,

wife got annoyed with me because of whatever thing.

I already hate them myself, yeah.

Overall, the trip was awesome.
