When taking a bath, the temperature of the water should not be too high. Use mild shower gel and soap, don't wash it hard, so as not to damage it. Be sure to rub lotion after bathing, and choose products with good moisture retention to prevent skin keratinization.
Then use keratin Shuhua cream to improve it. Use it every morning and evening, and your skin will become smooth in about a month.
Never scratch or scratch at ordinary times. Otherwise, it will cause inflammation and pigmentation, which is more difficult to recover.
