In addition, vitamin C is also involved in the synthesis of collagen, which helps maintain the elasticity and firmness of the skin.

 

Niacinamide (vitamin B3) : Niacinamide has a variety of benefits in skin care, including regulating skin oil secretion, reducing skin inflammation and redness, improving uneven skin tone, and enhancing skin barrier function. It can also promote the production of collagen and elastic fibers, improve the skin's firmness.

Vitamin E: Vitamin E is also an antioxidant that helps protect the skin from free radicals and environmental pollutants. It also has anti-inflammatory and repair properties for damaged skin, which can reduce signs of dry, rough and aging skin.
