What to do with keratin hardening? Pay attention to it early and you will feel better sooner

The skin on our body needs to be exfoliated, mainly to remove aging skin cells and rough cuticles, so that new cuticles can grow again. Therefore, it is necessary to exfoliate regularly, and also pay attention to skin care, pay attention to sun protection and so on.

1. Reasons:

1. Every winter, the number of patients with chapped skin in outpatient clinics increases significantly. Chapped skin is closely related to the following factors. The first is thickening of the stratum corneum, followed by dryness. The third is cold. The triggering factor is excessive activity. This disease will occur in any part that meets the above conditions. There are many causes of thickening of the stratum corneum, such as infection, eczema, long-term friction or repeated chemical stimulation, allergies, and some hereditary diseases, etc. The most common one is the "ringworm" caused by dermatophytes, commonly known as goose foot madness. When dermatophytes invade the stratum corneum, on the one hand, they accelerate the surface growth rate, while at the same time delaying the shedding of the stratum corneum, thus causing the local stratum corneum to thicken significantly.

2. In addition, with the increasing number of daily necessities, the chemical stimulation to hands caused by various chemical detergents has also increased significantly, and diseases such as "housewife hand" have also become more common. Once the stratum corneum of the epidermis thickens, the thickened skin will obviously harden in cold seasons. At the same time, since there are no sebaceous glands on the palms and soles of the hands and feet, it is difficult to retain moisture in the dry season, which causes local skin dryness and cracking. In addition, the hands and feet are the parts of the body that each of us must stretch and exercise frequently every day. Therefore, it is natural that the hands and feet are prone to chapped skin. Just like a piece of thin paper will not crack if it is bent repeatedly, the principle is similar, while cardboard will crack on its surface after being bent several times.

3. However, when the weather changes suddenly, the air becomes dry, life becomes abnormal or cells age naturally, and other external factors exist, the stratum corneum will be deprived of moisture and the skin will become hardened and dry. At the same time, some allergens, such as pollen and pollutants in the air, clog the holes in the skin fibers and cause skin problems.

II. Treatment

1. Perfect skin is firm and elastic. It relies on NMF (natural moisturizing factor, located in the stratum corneum of the epidermis, responsible for monitoring the amount of water loss on the skin surface. If too much water is lost from the surface, the skin will feel dry. Ideally, the water content in the stratum corneum should be between 15-20%. The stratum corneum can more effectively retain moisture and provide deep moisturizing to the skin) and intercellular matrix to maintain skin lubrication and softness.

2. Use lotion to calm the skin, wet the cotton pad, and gently pat to supply moisture to the skin. Apply moisturizing essence and moisturizing lotion to allow the skin to drink water while also having a clean, refreshing and breathable environment.
