Under-eye and neck concern
Crepey skin
Why under-eye skin turns thin and crinkled, and what can help.
Crepey skin is thin, loose and finely crinkled, like crêpe paper. It follows the loss of collagen and elastin.
Crepey skin
A fine needle places polynucleotide just beneath the skin, where collagen and elastin are made.
Why it happens.
- Less collagen
- The skin’s support structure thins with age.
- Less elastin
- Skin stops springing back and starts to sag in fine folds.
- Sun exposure
- UV speeds up the breakdown of both.
What can help.
Polynucleotides support the cells that make collagen and elastin, improving density over a course of treatment.
