About Vitamin C

Vitamin C is a brightening and antioxidant ingredient often chosen for dullness, uneven tone and early visible ageing. It works especially well in morning routines when paired with sunscreen. The right formula should feel comfortable enough for consistent use, because glow and tone improvement take patience.

Key Technology

Vitamin C may appear as ascorbic acid or a derivative, often supported by vitamin E, PHA, hydrators or antioxidant SPF. Some formulas focus on radiance, while others target photoageing or uneven tone. Sensitive skin should consider texture, strength and frequency before jumping into the strongest option.

How to Choose

Use vitamin C in the morning if the product directions allow, then follow with moisturiser and SPF. Choose a lower-stress formula if your skin is sensitive or already using retinol or acids. For dark marks, pair vitamin C with daily sun protection and a patient routine.

Vitamin C FAQs

Common questions about Vitamin C products and routines.

Which vitamin C product should I choose for my skin?
Choose by concern and tolerance. A pure L-ascorbic acid serum is often used for radiance, visible ageing and photodamage, while gentler vitamin C derivatives may suit sensitive skin better. SkinCeuticals C E Ferulic focuses on visible ageing and radiance, while Phloretin CF is positioned more toward discoloration and uneven tone.
Should vitamin C be used in the morning or evening?
Vitamin C is commonly used in the morning because it pairs well with sunscreen as antioxidant support. Follow the directions for the exact product. If your skin is sensitive or already using acids or retinol, introduce vitamin C slowly and avoid adding other strong actives in the same week.
Why does vitamin C sometimes sting or irritate?
Some vitamin C formulas, especially low-pH L-ascorbic acid serums, can feel active on sensitive or compromised skin. Stinging is more likely if the barrier is dry, over-exfoliated or recently treated. Reduce frequency, apply moisturiser, or choose a gentler format. If burning persists, stop using it and rebuild the barrier first.
