What is the biggest factor affecting the skin?

What are the factors that affect the skin?

I think I'm food lol

I usually like sweet foods

I used to live on snacks and chocolate.

Since I stopped eating these snacks and am eating healthy food

Lately, I've even been told that my skin is smooth and my complexion has brightened up. ;; lol

Even if I don't get enough sleep, I don't really get breakouts and it seems to stay the same.

But if you get plenty of sleep, do a face mask every day, go to the dermatologist, and eat a lot of sweets...

Pimples started appearing, and my face felt dry and rough.

I totally relate to the Kim Hye-soo snack meme lololol
