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 inside look at the cosmetic industry. This is episode 425 I'm your host, Valerie George, and with me today is Perry Romanowski. Hi Perry.

Perry Romanowski (0:27)

Hello Valerie, great to see you as always.

Valerie George (0:29)

Great to see you. On today's show, we're gonna cover a lot of questions, including is it a good idea to put pure glycerin on skin? Can a salon professional attend a cosmetic chemist course?

Why don't all Amlactin lotions smell bad? Is there a good two-in-one shampoo on the market? And finally, are there differences in ingredient quality between brands? But first, that chit chat.

Perry Romanowski (0:50)

Valerie, guess what I did.

Valerie George (0:53)

You didn't complete your juggling streak. It's broken.

Perry Romanowski (0:58)

No, no, I still have the juggling streak going. Day 6,382 today. But no, no, here's what I did.

Micro-needling. Can you believe it?

Valerie George (1:08)

You went micro-needling?

Perry Romanowski (1:12)

Well, no, no. Actually, I'm taking care of these kittens, and the kittens, when I'm feeding them, they just will run up my pants.

Valerie George (1:23)

Oh gosh.

Perry Romanowski (1:23)

And they just get their nails in my pants and just claw. So if you look at my legs, they look like they have all these little puncture wounds in it, and it looks like I've been doing micro-needling.

Valerie George (1:36)

I've got so excited for a second, and now I'm deflated.

Perry Romanowski (1:43)

I mean, it looks really bad. In fact, you know what, for patrons, I'm going to share the little video I did of the kittens.

I do this, I actually have been doing TikTok of Porch Kitties, and so there's a little video I did, a short one, which showed the injuries that these little kittens are causing me, but they are so darn cute.

Valerie George (2:04)

I bet you those injuries are worse than actual microneedling injuries, because microneedling, your face gets really bright red, you get some downtime, but you don't get long lasting wounds.

Perry Romanowski (2:15)

I imagine these little kitten nails, which are going through genes, by the way, I imagine they must puncture much deeper than a microneedle, right? Microneedles don't puncture deep enough to injure you, right?

Valerie George (2:30)

Well, it's like a little mini injury. I would guess that the nails are actually much larger than the microneedling implements.

Perry Romanowski (2:37)

Oh, right.

Valerie George (2:37)

And this is what you're feeling.

Perry Romanowski (2:40)

That's probably it.

Valerie George (2:41)

But they didn't do your face. What you need is to have them do your face and then couple it with a serum.

Perry Romanowski (2:48)

That sounds like a lot of work.

Valerie George (2:51)

Oh, gosh. Well, I'm excited to see you in a couple weeks in person. When's the last time we saw each other? That's right.

Perry Romanowski (2:59)

Oh, it must have been last, probably December in New York.

Valerie George (3:02)

Yeah, that's true.

Perry Romanowski (3:03)

Or was it? Yeah, it was New York.

Valerie George (3:04)

Yeah, New York again. But yeah, I'm looking forward to it. It's an ingredient show. I just went to one in Europe, but this one's some of the same stuff, a little bit different. But yeah, I have a lot of meetings scheduled and I'm ready to go.

Perry Romanowski (3:17)

Oh, fine. Well, we'll schedule a little meet up ourselves on Tuesday the 19th.

Valerie George (3:24)

I'm looking forward to it.

Perry Romanowski (3:27)

Actually, Valerie, I do this little project where I take pictures of the number 44 wherever I see it, because 44 is my favorite number.

Valerie George (3:34)

That's right. It's also your birthdate 44

Perry Romanowski (3:36)

Oh yeah, that's right. But one of our patrons, Zach, he sends me in these articles that he sees, wherever he sees the number 44

Valerie George (3:48)

Okay.

Perry Romanowski (3:49)

I come up randomly in an article.

Because when I was formulating, I used to put 44 in my formula somewhere, but he was reading this astrophysics thing about solar and stellar astrophysics. Wow, Zach, look at you.

Valerie George (4:06)

I wonder what you do for a living.

Perry Romanowski (4:08)

I don't know.

Valerie George (4:09)

Pretty impressive. I was reading the title of the article and I was like, I literally don't know what this is about.

Perry Romanowski (4:15)

Yeah, this Nova Aquilae, it faded by 0.44 Mags per century.

0.44 is there. It's a brightness average.
