Why Vitamin C is Essential for Anti-ageing
Vitamin C (L-ascorbic acid) is a powerful antioxidant that offers multiple benefits:
Proven Benefits
- Collagen Synthesis — essential for maintaining skin firmness and elasticity
- Brightening — inhibits melanin production to reduce dark spots
- Antioxidant Protection — neutralises free radicals from UV and pollution
- Photo-Protection — when combined with SPF, provides enhanced protection
- Hydration — helps skin retain moisture for a plumper appearance
What to Look for in a Vitamin C Serum
Concentration
Effective serums contain 10-20% L-ascorbic acid. Higher isn't always better — concentrations above 20% can cause irritation without additional benefit.
pH Level
L-ascorbic acid requires an acidic pH (below 3.5) for optimal penetration. Professional formulations are carefully pH-balanced.
Stabilisation
Vitamin C is notoriously unstable. Look for:
- Vitamin E — synergistically enhances efficacy
- Ferulic Acid — doubles photoprotection and stabilises the formula
- Dark glass bottles — protect from light oxidation
Formulation Type
- Water-based serums — best for normal to oily skin
- Oil-based formulas — better for dry skin
- Derivative forms — for sensitive skin (ascorbyl glucoside)
How to Use Vitamin C Serum
When to Apply
Morning application is ideal as vitamin C provides antioxidant protection against daytime environmental stressors.
Application Steps
- Cleanse your face and pat dry
- Apply 4-5 drops to face and neck
- Wait 1-2 minutes for absorption
- Follow with moisturiser and SPF
Building Tolerance
- Start with every other day application
- Gradually increase to daily use
- Some tingling is normal; burning or redness indicates sensitivity

Common Questions
Can I use vitamin C with retinol?
Yes, but use them at different times — vitamin C in the morning, retinol at night.
How long until I see results?
Brighter skin within 2-4 weeks. Significant improvements in fine lines after 8-12 weeks.
Why has my serum turned orange?
This indicates oxidation — the vitamin C has degraded. Discard and replace.
