Well, hello, hello, guys. You're listening to Beauty Bites with Dr. K, Secrets of a Plastic

Surgeon. And today on the podcast, it's time for a five-minute

Friday. I'm going to talk to you all about hyleronic acid. And if you don't know what this

ingredient is, you need to know. This is one of the top best-selling ingredients in skin care

from the last two years. And hyluronic acid is an amazing product that's found not only

in your natural skin, but also in all of our fillers. And I am a big believer in using

hyloronic, starting in your 20s even. As we age, we lose so much hyaluronic from our skin. So I

thought today we could do a question and answer

all about haleronic acids.

So if you've heard anything about haleronic acid,

you might have heard about different molecular weights

and sizes.

It's sometimes confusing, because you'll hear

about skin care referencing low, medium,

and high molecular weights.

And I wanted to explain that.

So the weight of a molecule is its density, and the molecular size is the actual occupation

of three-dimensional space of that molecule.

And so in order for hyluronic acids to penetrate the surface of the skin appropriately,

they need to be small.

They need to be broken into particle sizes and molecular sizes that can penetrate through

epidermis and down into dermis and to hydrate and reach the areas that they need to go to.
