The Complete Korean Vitamin C Routine: Cleanse, Ampoule & Mask
Vitamin C is the backbone of Korean brightening care — but a single product rarely does the job on its own. A proper vitamin C routine works in layers: a cleanser that clears the way, an ampoule that does the daily heavy lifting, and a sheet mask that delivers a concentrated boost. Here is how the three fit together, in what order, and how often.
The three-step vitamin C routine
Vita C Enzyme Powder Face Wash
Papain and bromelain enzymes clear away the daily buildup and dead surface cells that block everything you apply next. Powder-to-foam, no scrub particles. Use daily, AM and PM.
13.5% Pure Vita C Ampoule Serum, 30g
The engine of the routine. 135,000 ppm pure vitamin C with glutathione in a stabilized dual-layer formula, applied after toner and left on the skin. Use daily, AM and PM.
Vitamin C Face Mask, 5 Sheets
A 10–20 minute concentrated session on a 100% TENCEL sheet — the fastest visible glow in the routine, and the one to reach for before an event. Use 1–3 times a week.
What order do vitamin C products go in?
The rule in Korean skincare is thinnest to thickest, and it holds here:
- Cleanser → toner → ampoule → (sheet mask) → moisturizer → sunscreen (AM only)
If you are using both the ampoule and a sheet mask on the same day, let the ampoule absorb first and then apply the mask — or simply alternate: ampoule on most days, mask on the two or three days you want extra radiance.

Common vitamin C routine mistakes
- Judging it in a week. A mask shows an immediate glow, but tone changes take consistent weeks. Give the routine time.
- Letting the mask dry out. Remove a sheet mask at 10–20 minutes — a drying sheet pulls moisture back from the skin.
- Ignoring stability. Vitamin C oxidizes. If a serum has turned brown, its potency has already dropped — which is why a stabilized formula matters.
- Over-exfoliating alongside it. An enzyme cleanser already gives gentle daily exfoliation; stacking strong acids on top can leave skin irritated.

Vitamin C routine — FAQ
In what order should I apply vitamin C products?
Thinnest to thickest: cleanser, toner, ampoule, sheet mask (if using), moisturizer, and sunscreen last in the morning. If using both ampoule and mask, let the ampoule absorb first, or alternate days.
Should I use vitamin C in the morning or at night?
Both work. Vitamin C is an antioxidant, so many prefer it in the morning under sunscreen; others use it at night. The 13.5% ampoule is designed for twice-daily use. Either way, daily sunscreen matters.
Can I use a vitamin C cleanser, ampoule and mask together?
Yes — they work at different depths and durations. The cleanser rinses off, the ampoule stays on, and the mask gives a concentrated 10–20 minute session. Cleanser and ampoule daily; mask 1–3 times a week.
How long until I see results?
A sheet mask boosts radiance immediately, but tone changes need consistency — most people use a vitamin C routine daily for several weeks before judging it. Results vary by individual.
