Vitamin C Serum — Why 20% Is the Right Concentration and How to Use It

Not all Vitamin C serums are equal. Concentration matters. Under 10% and you won't see results. Over 20% and it irritates skin. 20% L-Ascorbic Acid hits the sweet spot — potent enough to actually brighten, fade dark spots, and boost collagen without burning.

What It Does

  • Fades hyperpigmentation and dark spots in 2-4 weeks
  • Evens out skin tone
  • Boosts collagen for firmer skin
  • Protects against UV damage (works with SPF)
  • Gives immediate glow from day one

How to Use

Morning and night on clean skin, before moisturizer. 2-3 drops is enough. Layer SPF on top in the morning — Vitamin C and sunscreen are the most powerful anti-aging duo in skincare.
