I'm also curious about the density effect

I want to learn about the density effect.
I often come across articles like this because I have no choice but to artificially correct my skin and take preventative measures.
As I get older, I feel like I'm starting to see signs of aging and my skin is losing some of its elasticity.
Hmm, every time I look in the mirror, I feel like I see more wrinkles.

Then, the phrase I came across was density.
I don't know much about the density effect yet.

It's a principle that measures the skin's resistance value and corrects it with high-frequency energy to strengthen the skin's density, right??
Since it is difficult to reverse skin changes once they occur, I am trying to do this as a preventative measure.
Density, how does this work?

Are you satisfied with it?
