COSRX The Vitamin C 23 Serum — cosrx vitamin c serum
Editor’s Note
The cosrx vitamin c serum is a lightweight, fast‑absorbing brightening treatment that targets the look of dullness and uneven tone. If you search for cosrx vitamin c or the fan‑favorite cosrx vitamin c 23, this concentrated formula is the one shoppers mean: a water‑light serum that layers cleanly under moisturizer and SPF without pilling. The finish is silky—not sticky—so makeup glides on smoothly. Expect a gradual boost in radiance and a more even look to dark spots with consistent use. As with any cosrx serum vitamin c, keep it tightly closed and use promptly after opening for best freshness.
Vitamin C can oxidize when exposed to light or air; a slight color change is normal, but potency is highest when the serum is used consistently and stored cool and dry.
Features of cosrx vitamin c serum
A concentrated brightening serum designed to visibly even tone while remaining gentle enough to layer daily.
Caution: Packaging may vary; the same formula may arrive in updated packaging.
Benefits:
- Helps visibly brighten and even skin tone for a healthy, lit‑from‑within look.
- Supports a smoother appearance of dark spots and post‑blemish marks with regular use—what many call the cosrx vitamin c 23 effect.
- Lightweight slip layers well with essences and moisturizers; ideal under sunscreen.
- Antioxidant defense helps reduce the look of dull, tired skin (great AM pick for fans searching vitamin c cosrx).
- Water‑light texture means comfortable wear for most skin types, including combination and oily.
- A go‑to if you want results from a cosrx vitamin c 23 serum without heaviness or fragrance.
How to use
- AM/PM, after cleansing and toner/essence: Apply 2–3 drops of the cosrx vitamin c 23 formula to dry skin.
- Press to absorb: Smooth over face, focusing on areas of visible discoloration; avoid the immediate eye area.
- Seal it in: Follow with a moisturizer.
-
Morning must: Finish with a broad‑spectrum SPF 30 or higher every day for best brightening results (see the American Academy of Dermatology’s guidance on how to use sunscreen effectively).
Tip: If also using retinoids or strong acids, alternate routines (vitamin C in the AM, retinoid in the PM) to minimize irritation.
Major Ingredients
Ingredient spotlight (key highlights rather than a full INCI):

- Vitamin E (tocopherol): Commonly paired with vitamin C to help stabilize and boost antioxidant performance.
- Hyaluronic acid: Draws moisture to the skin for dewy comfort and a plump look; see AAD’s overview of hyaluronic acid benefits.
