1. In places with acne or acne marks, touch the same place with raw potato chips twice or three times a day, and the acne will disappear quickly and the acne marks will fade. 2. Apply yogurt and pearl powder to your face every night. It's basically a spoonful of yogurt and 0.6 grams of pearl powder. Wash it off when it dries. In addition: salt can also remove acne, whiten and brighten the skin. Salt is a condiment that we eat every day, but few people know that salt also has the effect of acne. Let's see: after washing your face, put a spoonful of fine salt in your palm and add 3-5 drops of water, then carefully stir the salt and water with your fingers, then rub it with salt water from top to bottom, and do a circular massage while rubbing. After a few minutes, when the salt water on your face is dry and white, wash your face with warm water, apply moisturizing lotion or continue normal skin care steps. Go on, wash your face once in the morning and once in the evening. This has a good cleaning and decontamination effect, and can remove the oil, acne and even "blackheads" accumulated in pores. However, the skin around the eyes should be avoided when massaging, and sensitive skin should be used with caution.
