There are small red spots on the hands

People's skin is very sensitive. With changes in weather, changes in one's own living habits, or irregular diet, it may cause acne or small red spots. Acne may not only appear on the face, but also on the head, arms, hands, and even the back. It is normal to have small red spots on your hands. It may be eczema, food allergy or other symptoms.

If the red spots on your hands are caused by food allergies or eczema, they will not have a bad effect on the body and will generally disappear automatically in about a week. However, we should not be careless as the red spots on your hands may be caused by other diseases. If the rash persists for a long time, you should see a dermatologist in the hospital.

Congenital type: This type of skin is almost flawless when young, but it is easy to develop various spots in adulthood. This is because the skin contains less melanin and is less able to resist the attack of ultraviolet rays. Because the stratum corneum is thin and has poor water retention ability, the skin is prone to feeling dry.

Acquired type: It is caused by human factors, and the greatest harm comes from improper exfoliation. In medicine, only when you suffer from "skin keratinization" do you need to soften and peel off the cuticle. In the beauty industry, the correct approach should be "desquamation", rather than removing a layer of "skin" (stratum corneum) like peeling an orange.

If you have sensitive skin, you need to treat yourself like a secret agent and be vigilant at all times when taking care of your skin. Because there are many ingredients in skin care cosmetics that can cause skin allergies, various biochemical ingredients, natural extracts and highly active materials with therapeutic effects have become popular in cosmetics in recent years. While skin care products are effective, they also bring more sensitive substances and irritants.

Most ingredients in traditional cosmetics are not easily absorbed by the skin and have little actual effect. Allergic reactions mostly come from the complex ingredients of fragrances. Because fragrances contain volatile ingredients with smaller molecules, they can easily penetrate the skin and cause allergic reactions. Modern cosmetics and skin care products emphasize high efficiency, so they must be able to penetrate the skin and act on deeper layers of the skin to produce noticeable effects. Therefore, compared with traditional cosmetics, it is more likely to cause skin reactions. For example, the fruit acid skin care products that have been extremely popular in recent years are one of them. In addition, ultraviolet rays are also the main cause of skin sensitivity. Many cosmetic ingredients, including the plant essential oil "bergamot" used in aromatherapy, will cause photosensitivity reactions if applied to the skin and then exposed to ultraviolet rays from the sun.

People's skin has a complex structure, and changes in weather, working environment, eating habits, and other aspects will have an impact on the skin. There are many reasons for the small red spots on your hands. They may be caused by certain diseases, allergies to the cosmetics used, or urticaria or eczema. If the small red spots on your hands persist for more than a week and do not disappear, you should go to the hospital for examination as soon as possible.
