Vitamin C serum benefits

Vitamin C is a miracle ingredient and a must-have in your skincare routine. According to Paula’s Choice, vitamin C is one of the most research-proven ingredients you can apply to your skin. On top of being one of the best antioxidants out there, vitamin C offers also the following benefits:

  • Fading hyperpigmentation
  • Boosting collagen
  • Reducing inflammation

Vitamin C benefit 1: Fading hyperpigmentation

According to Sciencedirect, Vitamin C is known to inhibit tyrosinase, the enzyme that is responsible for melanin activity. When our skin is exposed to sun rays, the UV light speed up the production of melanin which is the pigment that gives color to the skin. By inhibiting tyrosinase, topical application of vitamin C will help prevent the formation of brown spots.

Vitamin C benefit 2: Boosting collagen

Collagen is the protein of the body that is responsible for the overall health of bones, skin, and muscles. Unprotected exposure to UV light and environmental stressors can over the years reduce the collagen in your skin and that’s is when your wrinkles will start to form since your skin will start losing elasticity.

According to Sciencedirect, vitamin C is essential for the synthesis of collagen because is the essential cofactor for the two enzymes required for collagen synthesis.

Vitamin C benefit 3: Reducing inflammation

Research shows that topical use of vitamin C reduces inflammation, even after sun exposure (assuming you are wearing SPF).

There are many forms of vitamin C to choose from:

  • Ascorbic acid
  • Ascorbyl phosphate
  • Ascorbyl palmitate
  • Ethyl ascorbic acid
  • Tetrahexyldecyl ascorbate
  • Ascorbyl glucoside
  • Magnesium ascorbyl phosphate

Ascorbic acid is the purest and most effective form of vitamin C, however, it might cause some irritation for skin types that are sensitive. Research shows that all the other types of vitamin C mentioned above are effective and provide similar benefits to Ascorbic acid but are more gentle for the skin, making it suitable for all skin types, including sensitive skin.
