Facial dermatitis is a very common category of diseases in dermatology clinics, including seborrheic dermatitis, atopic dermatitis, and contact dermatitis (e.g., allergies caused by the use of cosmetics or acne creams). Although each dermatitis has its relative clinical features, they are prone to recurrence due to facial exposure and prior inappropriate treatment, stimulated by various factors (e.g., sunlight, spicy foods, cosmetics, and use of therapeutic medications). Facial dermatitis can cause unnecessary distress in the patient’s life, affecting the patient’s aesthetics and causing greater psychological depression. Because of the differential diagnosis of facial diseases and the use of medication, it is best to consult a dermatologist if you have “facial dermatitis”. Some patients buy drugs from pharmacies for convenience and use hormones repeatedly or for a long time (some so-called compound Chinese ointments may contain hormones), especially fluorinated hormones, which can easily lead to hormone-dependent dermatitis or hormonal rosacea. Recurrence of facial dermatitis can be tricky to treat clinically, especially when it comes to hormone-dependent dermatitis. Due to the diversity of clinical presentations, the final diagnosis of the disease may vary somewhat from doctor to doctor. However, for this type of disease, doctors should generally consider the treatment plan based on the patient’s etiology, triggers, rash pattern, previous treatment, and other factors. Patients usually need to pay attention to the following matters: 1, look for and avoid all kinds of triggering and aggravating factors, such as sun exposure, spicy food, cosmetics, hot air conditioning, etc.; 2, usually try to wash your face with cold water, you can use cold mineral water or cold water (put in the refrigerator fresh room can be) wet compress 3-5 times a day (gauze best 4-6 layers), 15-20 minutes each time, 3-5 times a day. After the wet compress, if the skin is dry, you can use some external hypoallergenic moisturizing cream. 3, try to reduce the use of cosmetics, can use not easily lead to allergies or irritation of moisturizing cream or drug cosmetics, such as Avène, skin care, Winona and other brands; for new brands or new batches of cosmetics, it is best to take a little rub behind the ears every day, for 3-5 days, to determine that will not cause allergies, then use in the face. 4.During an attack of dermatitis (such as when there is itching, dryness, redness, etc.), it is best to choose a weak non-fluorinated hormone or non-hormonal anti-inflammatory drug (such as tacrolimus, pimecrolimus and other ointments) and take antihistamines as appropriate, under the guidance of a dermatologist and according to the severity of the rash. 5. If available, see your doctor for regular follow-ups and necessary allergen testing at the hospital.
