How to Use Vitamin C
Apply in the morning on clean skin before moisturizer and sunscreen. Vitamin C and SPF together provide far more photoprotection than either alone. Introduce slowly if you have sensitive skin.
FAQ
What percentage should I use? 10-20% L-ascorbic acid is the proven range; start lower if sensitive.
Why did my serum turn orange? Oxidation. Store cool, dark, and tightly capped, and replace if deeply discolored.
AM or PM? Morning, for daytime antioxidant protection alongside sunscreen.
Conclusion
Timeless offers the best value, La Roche-Posay the best balance of potency and tolerance. Whichever you choose, pair it with daily SPF — that's how vitamin C delivers visibly brighter skin.
