Nano Recipe Vitamin C Pure Serum — 30 Ml, 1 Unit

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.
