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

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

408. I'm your host, Valerie George, and with me today is Ferry Romanovski. Hi Perry. Hey, Valerie. Are

you in a beaker? Well, nope, all the beauties in my brain. So on today's show, we're going to cover

lots of questions, including, is it a good idea to load up a product with active ingredients?

What do you think of the Zip Halo device? How do you remove mineral sunscreen from your skin?

What do humectants really do in hair? And finally, what is neogen plasma skin regeneration? But first,

that famous or infamous inane chit-chat. Valerie, you know how I hurt my

leg some time ago. And you know, I run all the time. So, correct. So it was like a torn

meniscus and I went to physical therapy is what you're supposed to go to. And I've gone a few times,

and I'm supposed to do these exercises at home. And, you know, for the first time I was good at the

exercise. And then I kind of just stopped doing it. Well, I thought you had this really great

sticituativeness. What happened? You know, I do have that for some things, just not for this.

I mean, and the other thing is, like, how do you know when you're better at something?

And I guess this also applies to, like, beauty products.

Like, how do you know if something's working?

Like, my leg is better, but I think if I would have done nothing, it would probably have been better, too.

So I don't know. How do you know you're better? You don't. Right. I mean, it still hurts when I bend it sort of a weird way. And then, you know, there's the whole doctor thing is like, hey, Doc, it hurts when I do this. I'll say, well, don't do that. So I don't bend my leg that way anymore.

Well, why don't you just start doing the exercises?

Because it's not convenient. You have to wrap a rubber band around my staircase, and I got to do that.
