Hi, I'm Perry, and you're listening to the Beauty Brains, a show where real cosmetic chemists answer your beauty product questions and give you an insiders look at the cosmetic industry. This is episode 308. I'm your

host Perry Romanowski and with me today all the way from California.

Valerie George. Hello Valerie. Hi Perry. On today's show we are going to answer questions about

what's up with River saw and what are our thoughts on laser treatments for people with Rosatia?

Is retiname micro as good as Tretinin?

Can niacinamide and ascorbic acid be mixed?

And does fragrance dry out your hair. This is a whole

cacophony of different types of subjects, huh? Yeah, wow. But before we get to

that and before we get to the beauty science news

Valerie how's it going? It's going good I had a total

call it old person moment a couple days ago while you were out raising funds to help research for children with cancer,

I was bent over stuck in bed because I pulled a back muscle

Oh no. this week.

Does that happen to you frequently?

It's never happened to me.

Simply bending over to the ground to pick something up and I got stuck

a spontaneous giant knot formed on half of my back.

I'm not even kidding you and I had to go to the doctor

Monday to get some work on it. Yeah, it was not good. But the good news is I can walk again and I'm sore but I'm not in writhing pain like I was and basically what happened is that pulled a muscle that's it.

Wow well you know that's the sort of thing that I did notice as as I got older like I would lay on the

couch wrong and then my back would hurt for a week.

So what?
