Sanfe Spotlite Sensitive Areas Lightening Serum 50ml is used for promoting a more even skin tone and addressing hyperpigmentation in sensitive areas such as the underarms, inner thighs and the bikini area. This lightweight, non-greasy serum is enriched with a unique blend of ingredients, including kojic acid, 4% niacinamide, vitamin C and hyaluronic acid, all working together to nourish, hydrate and target dark spots while improving overall skin texture. Kojic acid may help inhibit melanin production, which may help lighten dark patches and promote a brighter appearance. Meanwhile, Niacinamide and Vitamin C contribute antioxidant protection and may support skin renewal, helping to reduce the appearance of uneven tone and roughness.
