RETONIL/RETINOIDS
What Is It:
A derivative of vitamin A, retinol reduces the appearance of fine lines
and deep wrinkles to improve the look of collagen-depleted skin, while
complementing the skin’s natural process to reduce the appearance of
pore size.
How It Works:
Retinoids work on a molecular level because skin cells contain retinoid
receptors that help regulate certain functions. With age and sun damage,
these functions deteriorate. The regular use of a retinoid helps to
normalize these functions. Retinoids improve skin texture and reduce
dark spots by speeding up skin cell turnover that slows down as we age.
They reduce blackheads and minimize pores, both of which worsen with too
much sun exposure. But the most powerful effects of retinoids are on
collagen, the building blocks of the skin. Retinoids have a dual effect
here: They not only help to decrease the amount of collagen breakdown
from sun exposure by preventing the rise of an enzyme called
collagenase, but they also help to stimulate the production of new
collagen.
