What is Vitamin C Serum?

Vitamin C Serum is a concentrated skincare product designed to deliver a high dose of L-ascorbic acid (the most active form of Vitamin C) and other antioxidants directly into the skin.

Typically lightweight and fast-absorbing, it is a treatment product used after cleansing and before moisturizing. Its primary functions are to:

Brighten the complexion and fade dark spots by inhibiting melanin production.

Stimulate collagen synthesis, which helps to reduce the appearance of fine lines and wrinkles.

Provide powerful antioxidant protection against environmental damage like UV rays and pollution.

Soothe inflammation and can help with skin redness.

Vitamin C serums come in various forms, with L-ascorbic acid being the most potent and Vitamin C derivatives (like Sodium Ascorbyl Phosphate or Tetrahexydecyl Ascorbate) often being more stable and gentler for sensitive skin. To protect its potency from degrading, it is often packaged in dark, opaque, or airless bottles.
