Acid brushing can solve enlarged pores. Clinically, you can improve enlarged pores by brushing fruit acid or salicylic acid on the skin. Enlarged pores are mainly due to the accumulation of more and more old keratin on the skin, which can cause the stratum corneum to become thicker and rougher, pores to become enlarged, and the skin to become dull and dry. Acid brushing is the use of a therapeutic concentration of fruit acid or salicylic acid applied to the skin, which can remove excess waste keratin through chemical exfoliation and promote normal skin cell metabolism to improve enlarged pores. It should be noted that the skin is usually more sensitive after acid brushing and should not be brushed frequently to avoid skin irritation. In addition to acid brushing treatment, large pores also need to pay attention to skin hygiene and cleanliness, to avoid the accumulation of keratin, dust and other substances in the pores, and usually need to pay attention to skin moisturizing, to avoid the skin is too dry. It is recommended that patients who are willing to be treated go to a regular medical institution for treatment to avoid adverse consequences.
