Follicular keratosis is most often seen as a red papular inflammation on both cheeks, upper extremities, buttocks and legs. Many hospital doctors think that it is a natural improvement after growing up and do not give treatment. As they grow older, many patients begin to suffer from the fear of wearing halter tops and shorts in the summer. They try all kinds of treatment methods, but the condition does not improve, but there is a large area of discoloration. The patient’s area has a special roughness, the lesions are pinpoint to corn size follicular papules, the skin is accompanied by a large area of discoloration, the tip of the light brown “horn embolism”, part of the curly hair contained within. The dermatology department of the Plastic and Cosmetic Center of the 309th PLA Hospital will determine the treatment plan according to the age and metabolic condition of each part of the body, and interval different times of fruit acid treatment, as well as the introduction of L-C to lighten the pigment, and the long-acting nourishing body cream to assist the treatment. Treatment: The treatment principle of fruit acid peeling is to use highly concentrated fruit acids to exfoliate the skin, to promote the shedding of the aging keratin layer, to accelerate the renewal rate of keratinocytes and a few upper epidermal cells, and to promote the proliferation of elastic fibers in the dermis, so as to make the skin smooth and elastic, which is usually clinically applied to large pores, dull skin, acne, post-acne acne marks, pigmentation, superficial acne scars, various pigmentation spots and uneven skin tone. Effect: Due to the keratinization of the opening of the hair follicle sebaceous gland, the formation of “keratosis” and sclerosis were more serious, and the inflammation was slightly red during the first few acid brushing treatments. The pores were unclogged, and the skin on the body became smooth and delicate. According to the treatment, for hyperpigmentation, we switched to the introduction of L-C as the main treatment for hyperpigmentation.
