What's going on with the red dots on my hands?

If there are red spots on your hands, you should pay attention to whether it is caused by skin allergies, because people with sensitive skin are prone to allergies. Common allergic symptoms are the appearance of red spots or erythema, so you need to understand the cause of the allergy and use the correct desensitization treatment.

1. Three characteristics of sensitive skin

1. The epidermis of the skin is thin, and the capillaries (red blood) under the skin can be easily seen.

2. The skin is relatively white, and therefore lacks proper melanin protection.

3. Dry skin, often itchy, and always red. Next are the categories and areas that need attention.

2. 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.

3. 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.

4. For sensitive skin, pay special attention to the following chemical substances in skin care products that are prone to cause allergies: alcohol, bronopol, sorbic acid, parabens, fragrance. If you don't want to cause allergies, pay extra attention when buying!
