I am worried about sagging and inelastic upper arm fat.

People try to improve skin elasticity through various cosmetics or treatments.

How should I manage sagging and inelastic upper arms?

I don't really mind it when wearing long sleeves, but I am really self-conscious about it when wearing short sleeves...

When I see my sagging upper arms lacking any elasticity, even when wearing a sleeveless top, I realize that I urgently need to take care of them...

Do you manage sagging upper arm skin with cosmetics or procedures?

If you have any maintenance tips other than exercise, please share them! ^^
