That black block is pockmarked, and the problem can't be completely solved by buying it from outside, including Zeping and Dipox. If it is not very powerful, it can be diluted by eating more whitening foods such as milk, soybean milk and almonds. The homemade banana mask also has certain effects. If it is serious, then go to plastic surgery and remove it with physical therapy such as laser.
As for large pores, it is a common skin problem. First of all, you need a facial cleanser that suits you, preferably neutral! Then choose an emulsion that shrinks pores, but don't buy alcohol! They are sold in these markets. We recommend FACE SHOP because all their products are made of plants. Please consult the counter assistant for details!
