GOODAL Green Tangerine Vita C 15 Ampoule is a vitamin C serum formulated for daily facial care. It contains 15% pure vitamin C derived from green tangerines, a natural source of antioxidants and ascorbic acid. The serum is designed to help reduce the appearance of fine lines and address dull, uneven skin tone. Its lightweight, water-based texture absorbs quickly without leaving a sticky or greasy residue, making it suitable for most skin types, including sensitive and combination skin. The product emphasizes a gentle approach: the vitamin C is stabilized to minimize irritation while maintaining efficacy. Green tangerine extract, rich in hesperidin and vitamin C, provides additional nourishment to support a brighter complexion over time. Hydrating ingredients such as glycerin and hyaluronic acid help maintain moisture balance during application. This ampoule is part of a K-beauty routine that prioritizes skincare layering, and can be used as a targeted treatment step before moisturizer. Suitable for those seeking a mild yet active vitamin C option, it offers a practical entry point into everyday brightening care without harsh exfoliants or high-concentration acids. The 16g (0.56 oz) tube packaging allows controlled dispensing and preserves the formula’s freshness. As with any active skincare, a patch test prior to full-face use is recommended, and consistent application over several weeks supports gradual improvement in skin radiance and texture. This product does not claim instant or dramatic transformation, but rather regular, gentle support for skin’s natural renewal process.
