Self-foaming bubbles are usually very useful for removing blackheads. Small bubbles can mainly remove keratin from the face, and at the same time, they can also give skin muscles a hydrating effect, which can deeply clean the skin and remove dirt accumulated in pores, thus removing blackheads. Generally, after removing blackheads with small bubbles, we should pay more attention to facial skin care and avoid using irritating cosmetics to avoid irritating facial skin.
