Common ingredients in skincare may include retinol and retinoic acid. These agents are important in the stimulation of skin cells and can aid in preventing and correcting signs of aging. Retinol and retinoic acid are derivatives of vitamin A. Vitamin A is a stimulant that increases oxygen circulation in the skin. Vitamin A stimulates both the epidermis and dermis, making it an important ingredient to achieve younger, healthier skin.
Affecting the Epidermis
On the top layer of the skin, the epidermis, vitamin A stimulates the epidermis and affects it in the following ways:
Restores the water, lipid, and protein balance (restores skin barrier function)
Induces superficial exfoliation to promote cell turnover and improve skin texture
Improves a healthy skin cell turnover cycle
Purges existing pigmentation in the skin
Inhibits melanin production
Affecting the Dermis
Even deeper in the skin, vitamin A stimulates the dermis and improves the skin in the following ways:
Stimulates fibroblasts to increase collagen and elastin production
Improves skin firmness and elasticity and reduces the appearance of fine lines and wrinkles
Improves natural hydration
Maximizes the delivery of nutrients and the removal of waste material
Inhibits the breakdown of collagen
Arguably the most important product in your skincare regimen is a retinol or retinoic acid. However, be sure to talk to a skincare professional before reaching for an over-the-counter retinol or retinoic acid.
