Key benefits (claims) Reduces pigmentation: Helps fade age spots, sun spots, melasma, and post‑inflammatory hyperpigmentation. Brightening / whitening: Promotes a more even, radiant complexion. Antioxidant protection: Vitamin C provides antioxidant defense against free radicals and environmental damage. Collagen support: May stimulate collagen synthesis, improving skin texture and firmness.

How to use Cleanse and tone the skin. Apply a few drops of the ampoule/serum to the face (and neck) after water‑based steps, before heavier creams/oils. Start with every other day application if you have not used vitamin C before, then increase to daily (morning or evening). In the morning, follow with a broad‑spectrum sunscreen (SPF 30+) — essential when using brightening/active treatments. Avoid combining with strong acids (AHAs/BHAs) or retinoids at the same time without monitoring for irritation; consider alternating nights or using lower concentrations.
