The hair on the legs curls into small black spots

The skin of the leg hair feels smooth, but there are small black spots at the pores. There are many small bags on the limbs, which are very rough. This situation is very common, especially prone to occur on the outside of the upper arms and legs. It is a skin disease also called keratosis pilaris. It is caused by keratinization of the hair follicle opening, which affects the growth of vellus hair, so the skin surface does not feel smooth. Indeed, there is a curly sweat hair in each small papule.

This is a hereditary skin disease, mainly caused by keratinization of the hair follicles, which is closely related to fat metabolism. Generally, some fat people are more likely to have this condition. In addition to affecting the appearance, keratosis pilaris has no effect on life.

Suggestions: Taking vitamin A orally or eating more foods rich in vitamin A can help with this disease; in addition, topical skin keratin softening or keratin dissolving agents can alleviate symptoms and make the skin surface smoother. For example, topical retinoic acid, salicylic acid ointment, etc. The application of retinoic acid should start with a low concentration, such as 0.05%-0.1%, to avoid irritation to the skin, and use it once a day at night. The drug needs to be used for a long time to be effective. You can scrub it with a slightly rough bath towel when taking a bath, but not too hard. Frequent rubbing can make the skin smoother. Another way is to use a rough bath towel and scrub it with beer. Do this after bathing, twice a week. This method must be persisted for a long time to be effective. You can also buy urea ointment. One tube is very cheap, but the quantity is not much. If you keep using it, it will still cost you money!

You can also apply some moisturizing skin care products to reduce dry skin, which is helpful. In addition, since vinegar is also acidic, it can soften the cuticle, so you can dilute the vinegar with an appropriate amount of water and apply it to the skin. White vinegar is best. Can patients use exfoliating bath products, such as scrubs, exfoliating brushes, loofahs, etc. Can you use retinoic acid cream externally? Moderate exfoliation is helpful for this disease, but excessive exfoliation will cause skin damage. Excessive friction will not only damage the skin, but also make the stratum corneum thicker. Therefore, exfoliation once or twice a month is enough
