Gentle serums and vitamin C creams make an easy start for skin that is new to vitamin C, with stronger formulas to step up to later. Vitamin C belongs in the morning after toner, with sunscreen on top to protect the brighter tone you are working for.

questions, answered.

Which vitamin C serum should I start with?

If your skin is sensitive, the Klairs Freshly Juiced Vitamin Drop or the Beauty of Joseon Light On Serum: Centella + Vita C both brighten gently, and the Light On serum layers easily under makeup. Once you know your skin likes vitamin C, the watery COSRX The Vitamin C 13 Serum is the next step up, light enough for morning and evening.

Pure vitamin C or a derivative?

Pure vitamin C, or ascorbic acid, tends to work faster on the look of dark spots but can sting some skin and loses strength in light and heat. Derivatives are steadier and softer, which makes them easy daily picks. If you want pure vitamin C that keeps its strength, the water-free TIA'M Vitamin C 24 Surprise Serum stays stable against light and heat.

Can I use vitamin C with niacinamide or retinol?

Niacinamide, yes: many Korean serums combine them, such as the Cell Fusion C Toning C Dark Spot Serum, a light morning layer for dark spots. Retinol belongs to your evening routine and vitamin C to your morning one, and give strong acids a night of their own. If skin feels tight, use vitamin C every other day to start.
