This is a bottle of 30 ml of 2% Kojic Acid Face Serum which also contains niaciamide and 1% Alpha Arbutin from Derma co, I love this brand. This serum is Amazing for Hyperpigmentation and dark spots, this is my second bottle and honestly my dark spots are gone and I don’t need this anymore, so if there is anyone out there who needs this and wanna try something new, come and buy it for low price!😉🥰I have used it very little so don’t worry about the quantity.
