Goodal Green Tangerine Vita C Dark Spot Care Serum is a Korean brightening serum built around green tangerine extract sourced from Jeju Island, combined with niacinamide and ascorbyl glucoside (a vitamin C derivative). It is formulated to help target uneven skin tone, dark spots, and dullness, with regular use over time helping skin appear brighter and more even. The lightweight, gel-like texture absorbs quickly without leaving a sticky residue, making it comfortable for daily use, including for those with sensitive skin. It's a good pick for anyone dealing with post-blemish marks or dull, tired-looking skin who wants a brightening step in their routine. Apply a few drops to clean skin morning and/or evening after toner, gently patting in before following with moisturizer and, in the daytime, sunscreen.
