Restores skin's natural bounce and elasticity

Skin gradually ages and loses elasticity over time. This is a natural phenomenon that can’t be prevented or avoided. However, you can delay the process by replenishing the skin of its collagen & natural elasticity and repairing damage of time.

This night serum is designed to combat various causes of aging, and rewind time to improve the appearance of fine lines and wrinkles, through a dual peptide formula strengthened by EGF (sh-Oligopeptide-1) and bFGF (sh-Polypeptide-1). While small in size, this 10 ingredient serum is perfect for use by everyone—regardless of age, to fight and prevent aging for a youthful complexion.

A lightweight night serum that helps skin look smoother, bouncier, and less tired over time.
