Stains are pigment deposits and will not be removed so quickly. If the effect of freckle removing products is very obvious at first, it is recommended not to choose this kind of skin care products, which may contain heavy metals and other ingredients. It takes about three months for real freckle removing products to see obvious effects. The combination of Haishengjin products I used before has a good freckle removing effect. If I insist on using it, I can cooperate with better skin care products, and the hydrating effect will be better.
