Product name
Nano Recipe Vitamin C Pure Serum (나노레시피 비타민 C 원액) — 30 ml, 1 unit
Overview
Purpose: A concentrated vitamin C (ascorbic acid or its derivative) serum designed to brighten skin tone, reduce hyperpigmentation, boost radiance, and provide antioxidant protection against environmental damage.
Formulation note: “원액” implies a high‑concentration, minimal‑additive formulation (a pure/near‑pure vitamin C solution), which can be more potent but also more potentially irritating than diluted serums.
Key benefits
Brightening: Helps fade dark spots and even skin tone with consistent use.
Antioxidant protection: Neutralizes free radicals from UV exposure and pollution, supporting anti‑aging.
Collagen support: Vitamin C aids collagen synthesis, which can improve firmness and reduce fine lines over time.
Radiance: Regular use gives a healthier, more luminous complexion.
Typical active ingredient
L‑Ascorbic Acid (pure vitamin C) or a stable derivative (e.g., sodium ascorbyl phosphate, magnesium ascorbyl phosphate) — check the INCI to confirm which form is used and its concentration.
How to use
Patch test first: Apply a small amount behind the ear or on the inner forearm for 24 hours to check for sensitivity.
AM or PM use: Can be used in the morning (under sunscreen) or at night. If used in the morning, always apply sunscreen after to prevent photo‑irritation.
Application order: After cleansing and toning → apply vitamin C serum (a few drops) → follow with moisturizer and sunscreen (AM).
Start slowly: If you’re new to vitamin C or have sensitive skin, begin with every other day and build up to daily use as tolerated.
Storage: Vitamin C (especially L‑ascorbic acid) is oxidation‑prone — store in a cool, dark place; keep the cap tightly closed; refrigerate if recommended by the brand. Replace once color changes (yellow/brown) or odor appears.
