Hi, I'm Perry, and this is 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 from the perspective of a scientist at the cosmetic industry. This is

episode 219. I'm your host Perry Romanowski and with me today is Valerie

George. Hello Valerie. Hi Perry, happy May. It's already May. Go figure. Well we've got a big show today because on today show we're going to be answering questions about whether the wait time is necessary when applying

acids to your face. How you go about debating the product safety with somebody, whether skin

products with natural moisturizing factor work better and if you should avoid

glycerin and dimethicone in your hair care products.

I know you're going to have a lot to say about that one, Valerie, right?

Oh yeah. Well before we get started with that and

some beauty science news let's get on with some of that chit-chat that were so

famous for.

Valerie, how are you holding up with this self-porantaining stuff?

I'm doing good.

I see that your governor in California just had to chase all the people away from the beaches?

Well, we have this rare algae bloom that is happening and it's creating this electric looking

wave when there's motion and the algae are disturbed at night or for

boats cutting through the water. You guys can Google it. It looks like electricity,

blue lightning in the water. It's pretty incredible. So people are flocking to the beaches. Also it's been like 90 degrees here.

This huge heat wave that first hit California and is kind of sweeping across the whole nation.

People want to go to the water.

It's silly, but I personally want to stay in air conditioning
