Your New Anti-Aging Partner – Retinol
Retinol, a derivative of Vitamin A, is known for its anti-aging and skin regenerative
powers. Just like Vitamins C and E, its vitamin counterparts in delivering brightening and anti-oxidating
results, retinol is widely used to formulate skincare products such as moisturizers and serums.
To understand how retinol repairs our skin, let's start by understanding our skin structure.
Our skin is made up of the epidermis, dermis and hypodermis, dermis, the middle layer of skin, is consisted of
collagen, elastin and fibroblast, of which collagen is the most important component to support the skin for a
healthy and plumped complexion. Collagen depletes over time and this can lead to fine lines and saggy skin -
this is when retinol comes into help. Retinol can reach the deepest layer of the dermis and to stimulate skin
cell turnover and collagen reproduction, which helps to minimize pores, smooth wrinkles and fine lines, refine
skin texture and restore skin's firmness.
