Redness and peeling of the face is very common in spring. It is commonly caused by the following diseases. 1. Allergic dermatitis manifests itself as sudden facial redness and peeling, accompanied by itching and a layer of small bumps floating on the surface of the skin when touched. The common reasons for this include: switching to a new skin care product, blowing in the wind, eating certain foods that are rarely eaten, eating certain irritating foods, etc. 2, seborrheic dermatitis manifested as recurrent facial erythema, surface flaking, not necessarily accompanied by itching. The most frequent sites are between the eyebrows, both sides of the nose and cheeks. 3, perioral dermatitis manifested as perioral erythematous flaking, dry and painful, more painful after contact with water and food. 4.White furfuraceous rash Prevalent in children, manifested as faint white patches on both cheeks, surface flaking. Boys are more common. Treatment and prevention, these diseases are relatively similar. First, try not to wash your face. Clear water is an irritant to allergic skin. Stop using skin care products, including cleansers, toners, creams, masks, etc. Do not wear makeup. When showering, do not let hot water or shampoo run down your face. Go out less when it is very windy. Take oral anti-allergy medication, one tablet of Keratan by mouth during the day and one tablet of paracetamol by mouth at night. Topical application of Protopic or Advil. For unused creams, try a small area first, if it is not more red and itchy, you can use it on other problematic areas. It is also recommended that medical skin care products be applied in conjunction with this. Problems with the skin are, in many cases, due to a disruption of the skin’s barrier function. Medical skin care products, which are free of preservatives, fragrances, colors and other substances that can easily cause allergies, help restore the barrier function of the skin. This results in faster treatment. Commonly used medical skin care products include Avène Triple Repair, Stave Facial Wash, etc. (Disclaimer, this is only a suggestion to aid treatment and not an advertisement) Diet with less spicy and stimulating foods.
