How Vitamin C Serum Works on Skin

As a skincare user, it's key to understand how ingredients actually work. This way you know what benefits to expect. Vitamin C serum’s benefits are wide-ranging. The list below takes you through all of them.

  1. Anti-oxidant Effect: Also called L-ascorbic acid, Vitamin C is a potent antioxidant. When skin is exposed to UV rays, pollution etc, it generates free radicals that can be damaging. Vitamin C neutralises these radicals. Thus eliminating oxidative stress that can damage your skin..

  2. Reduced Visible Dullness:  As a result of neutralizing free radicals, Vitamin C improves visible dullness on your skin. It in turn promotes glow.

  3. Supports Collagen Synthesis: Collagen is a protein which provides structure, strength and elasticity to your skin. Vitamin C helps in collagen synthesis, thus helping skin look smoother, firmer, and more even.

  4. Visible Results Over Time: Consistent application of the serum leads to a brighter-looking skin, improvement in tone, and gradual texture refinement.

Vitamin C can be quite unstable in its common form. It can lose efficacy when exposed to light, oxygen, high temperatures and more factors. Fеrulic Acid stabilizеs Vitamin C

Deconstruct’s 10% Vitamin C Serum is formulated with 0.5% Ferulic Acid. The latter component lends the serum heightened antioxidant properties along with helping stabilize Vitamin C. Hence more protection from sun damage and improved overall antioxidant performance.

How to Use Vitamin C Serum for Best Results

Application technique makes a very big difference if you wish to achieve the best results.

  • Use once daily, preferably in the morning.

  • Apply 2–3 drops after cleansing and before moisturizer and sunscreen.

  • Follow with a broad-spectrum SPF 30 or higher.

  • Avoid layering immediately with strong exfoliating acids if your skin is sensitive.

  • Take progress photos every 2-4 weeks. Changes are gradual and easier to notice side by side.

As results usually build over time, skipping days frequently can delay visible improvement. Hence, it is very crucial to understand how to use Vitamin C serum on face.
