Vitamin C a powerful antioxidant known for its ability to brighten, even out skin tone, and fight early signs of aging, a Vitamin C serum is an essential step in any daily routine. Applied before your moisturizer, it helps your skin absorb active ingredients more effectively and enhances the performance of your entire regimen.

What Is a Vitamin C Serum?

A Vitamin C serum is a lightweight, fast-absorbing liquid or gel packed with a high concentration of active ingredients — in this case, pure vitamin C. Unlike traditional moisturizers, serums are specially formulated to penetrate deeper layers of the skin, delivering visible results faster.

How Does Vitamin C Work?

Also known as ascorbic acid, Vitamin C is essential for skin health. It's a key component to skin regeneration and protection. A good vitamin C serum uses a stabilized form of the vitamin to shield skin from environmental damage, stimulate collagen production, and promote a more radiant, youthful complexion.

What Does Vitamin C Serum Protect Your Skin From?

Vitamin C serum is a powerful shield against everyday skin stressors that accelerate aging and dull your complexion. Here’s a list of what this antioxidant-rich formula defends your skin against:

  • Free Radicals: Neutralizes unstable molecules from pollution, UV rays, and stress, preventing fine lines and sagging.
  • UV Damage: Enhances skin’s natural defense against UV rays, reducing sun damage when paired with SPF.
  • Pollution & Environmental Toxins: Detoxifies skin and creates a protective barrier against pollutants.
  • Hyperpigmentation & Dark Spots: Inhibits melanin production, fading existing spots and preventing new ones.
  • Inflammation & Redness: Calms irritation, supports skin repair, and strengthens the skin barrier.
