Over time, it increases collagen and elastin production to help with lines and wrinkles, and even improves skin tone and texture by increasing blood circulation to the skin, Fusco says.  Still, if you’re looking for a permanent fix, cosmetic dermatologists are quick to point out that this is not it.
