I have repurchased it many times. I have tried applying a mask before, and the effect of the serum skin care products has not changed much... Since I encountered it, I feel that it is no longer a problem to want fair and translucent skin, this is really true. After taking 2 bottles, you can already see a degree of skin whiteness, white from the inside out. Really like it. I don't want to be dark this summer, I can only rely on it, an absolute good thing!
