Sensitive skin and skin allergy
Sensitive skin is not the same as skin allergy. Sensitive skin is a special state of skin that is susceptible to irritation. Patients with fragile skin and weak resistance to the outside world are prone to erythema, edema, capillary dilation and other symptoms after being stimulated by the outside world. Itching, tingling, burning, and tightness are consciously felt.
Skin allergy is a pathological reaction to skin stimulation by various allergens, manifested as skin redness, swelling, heat, pain, itching and other symptoms, and belongs to the category of allergic contact dermatitis.
