You can own great products and still get lackluster results if you apply them in the wrong order. Layering matters — here's the simple rule and the exact sequence for morning and night.
The golden rule: thinnest to thickest
Apply products from lightest texture to heaviest, so each one can absorb. Water-based serums go before oils and creams.
Morning routine (AM)
- Cleanser — start with a clean base.
- Vitamin C serum — antioxidants and brightening first.
- Moisturizer / brightening lotion — hydrate and seal.
- Sunscreen (SPF 30+) — always the final step of the morning.
Evening routine (PM)
- Cleanser — remove the day (add a gentle brightening soap or a scrub 2–3x a week).
- Treatment serum — your brightening actives.
- Moisturizer / lotion — richer at night to repair while you sleep.
Where do niacinamide and Vitamin C go?
Both are usually in serum or lotion form and layer easily. Niacinamide is gentle and pairs well with Vitamin C — you can use them together morning or night.
Common layering mistakes
- Skipping SPF (undoes your brightening work).
- Piling on too many actives at once when starting — introduce slowly and patch-test.
