Red spots on the upper body that do not hurt or itch

There are many possibilities for the appearance of small red spots on our skin. Generally, there will be pain or itching, which is very helpful for diagnosing the possible causes. Red spots on the upper body that are neither painful nor itchy are most likely caused by allergies. We can judge the specific characteristics based on our own characteristics and compare them with the symptoms of allergies. Once the diagnosis is confirmed, targeted measures must be taken for treatment.

Disease characteristics Skin allergies mainly have the following characteristics: Skin allergies are characterized by: 1. The skin epidermis is thin, delicate and fair, with less sebum secretion, relatively dry, obvious capillaries, and skin showing signs of dryness and hypofunction. The ability of the stratum corneum to retain moisture is reduced, and the sebum film on the skin surface is not fully formed.

2. Contact with cosmetics or seasonal allergies can easily cause skin allergies, resulting in redness, swelling and itching. The skin lacks luster and the cheeks are prone to redness and swelling. 3. Due to seasonal changes, the skin tends to be in an unstable state. The main symptoms are itching, burning, stinging, itchy skin and small rashes. 4. It is easily affected by external environment or substances such as cold wind, food, water quality, ultraviolet rays, synthetic fibers, fragrance, pigments, etc. 5. When skin comes into contact with irritants, it can cause skin problems. Allergies may occur to sunlight, climate, water, plants (pollen), cosmetics, perfume, insect bites and high-protein foods.

Main types of skin allergies can be roughly divided into the following types: A. Dry skin allergies No matter what season, the skin is always dry and rough. Once you apply lotion, you will feel slight tingling, itching, and sometimes redness and swelling. People with these symptoms have dry skin allergies. The cause of skin allergies is dry skin, which leads to a decrease in the defense function. Just remove excess sebum and moisturize the skin sufficiently. B. Oily skin allergies: Acne and small particles are prone to appear on the face, and the face will become red, swollen and inflamed. Even dry areas such as the cheeks may develop acne. Experts say that people with these symptoms should be suffering from oily skin allergies. The cause of sensitivity is excessive sebum and insufficient moisture, which reduces the skin's protective function. Just remove excess sebum and moisturize sufficiently. C. Stress-induced skin allergies. During the change of seasons and before menstruation, cosmetics and skin care products become unsuitable. If you lack sleep or are under a lot of stress, your skin will become dry. People with these symptoms should suffer from stress-induced skin allergies. The reason lies in endocrine disorders caused by various external stimuli or hormonal imbalance. D. Permanent skin allergies such as allergic dermatitis or abnormal sensitivity to sunlight, fragrances, pigments, etc. Specific irritants (allergens) cause allergic reactions. If you continue to follow your daily skin care methods, it will be very dangerous. It is best to go to a dermatologist clinic immediately and use the skin care products recommended by the doctor.
