If the roughness on the face is like sandpaper, you need to carefully observe the skin changes in the rough areas. If the rough areas are concentrated on the sides of the cheeks in a dark red or white color without any conscious symptoms, it is considered to be follicular keratosis caused by simple genetic factors, and there is no way to completely cure it, only to apply adapalene gel or compound lactic acid cream to improve the symptoms, which will lead to recurrence of the disease once the medication is stopped. If the roughness on the face is accompanied by slight itching, itchy skin surface can be seen obvious peeling, consider seborrheic dermatitis or allergic factors caused by facial dermatitis, related to poor rest, lack of sleep or allergic factors. You can choose to use oral cetirizine tablets or loratadine tablets and topical application of hyaluronic acid gel or human-like collagen moisturizing cream, which has a significant improvement effect.
