Why Use a Vitamin C Serum?
Vitamin C, the so-called ascorbic acid, is an antioxidant dynamo that:
- Fights free radicals
- Boosts collagen production
- Evens skin tone
- Brightens dull skin
- Fades acne scars and hyperpigmentation
However, it is not every serum that can be equal. The real result requires the best Vitamin C serum that suits your personal skin.
Essential Ingredients to Look for in a Best Vitamin C Serum
These supporting ingredients must be detected to pass as the best serum with Vitamin C:
- Vitamin E (Tocopherol): Enhances stability of Vitamin C and increases the antioxidant effect two fold.
- Ferulic Acid: Increases efficacy and increases shelf life.
- Hyaluronic Acid: It keeps skin hydrated and bouncy.
- Niacinamide: Soothes irritation and minimizes the size of pores (most effective within combination formulas).
- L-Ascorbic Acid (10-20%): Is the strongest and studied Vitamin C.
