My arm itches and the more I scratch it the more it itches

Many people often scratch their skin because of skin allergies. The more they scratch, the more itchy it becomes, and the more itchy it is, the more they want to scratch. This can cause local fungal infections on the skin. So everyone must pay attention to the fact that human nails are not guaranteed to be clean. It is very likely that some chemicals in manicures and bacteria in the crevices of the nails will infect the local skin. So try not to scratch if you have skin allergies, and use the correct method to treat it.

Precautions

1. Sensitive skin (or skin sensitivity) does not mean allergies. It is a popular description of a group of skin symptoms by non-professionals or beauty salons, and there is no such term in regular medical books.

2. Sensitive skin can be divided into two categories: dry skin and oily skin. Their medical names, causes, and treatments are very different.

3. People often describe dry sensitive skin, which has the following symptoms: dryness, tightness, redness, stinging, and peeling. Especially when exposed to cold stimulation (in winter and when washing the face with cold water), it is easy to cause erythema and dandruff, and even inflammation and swelling.

4. In beauty salons, sensitive skin is often believed to be caused by a thin stratum corneum and lack of water, and beauticians often recommend moisturizing and hydrating. Moisturizing and hydrating can relieve symptoms. Pay attention to the frequency of using the scrub. Depending on how your skin feels, you can use it once every two weeks or once a month.

5. It is very important to choose an amino acid moisturizing facial cleanser for sensitive skin. Harsh soaps, detergents, and fragrances in some moisturizers can irritate the skin and make it drier. Rubbing and scratching dry skin can lead to infection and scarring.

6. The key to treating dry skin is to keep it moisturized. Rinse less frequently to preserve the protective oils on your skin. Ointments and creams such as petroleum jelly, mineral oil, or unscented moisturizers can also keep the skin hydrated.

7. Oily and sensitive skin is very troublesome and cannot be solved by moisturizing. It is a general term for skin diseases mainly caused by oily skin not being cleaned properly, resulting in bacterial or fungal infections... Treatment is not easy and relapse is very likely. Be sure to use an antibacterial facial cleanser for cleaning.

8. Antibiotics and hormones can be used to temporarily control the symptoms of oily and sensitive skin, but antibiotics and hormones can only be used a few times and not frequently. When choosing skin care products, try to choose products that can improve skin function and use them for a long time to improve your skin's resistance.
