Facial dermatitis mainly manifests as recurrent erythema, rash, oozing, dry flaking, self-conscious itching, burning and stinging sensation on the face, which is prone to recurrent attacks and lasts for a long time, and patients are distressed by it, and even affects daily life and social life. The onset or aggravation factors of this disease: 1, local skin barrier destruction, skin thinning; 2, local contact with dust, pollen, cosmetics, sunlight and other allergens; 3, local friction, drugs (retinoic acid, peroxymethylene, glucocorticoids, etc.), chemical peeling and other stimulating factors; 4, mental tension, fatigue and endocrine dysfunction and other systemic factors. The details of daily life should be noted: avoid local massage and rubbing and washing with too hot water, or too frequent use of soap, facial cleansers and other skin cleansers, because these physical and chemical stimuli can change or damage the skin. When exposed to wind, cold and heat, the condition is often aggravated, and corresponding preventive and control measures should be taken, such as wearing a mask in winter and sun protection in summer. Try to use physical sun protection, such as using a visor-type sun hat, avoiding sunscreen stimulation, etc. Avoid inappropriate use of skin care cosmetics. Due to the influence of frequent advertising in the media, many women friends blindly pursue novel or expensive brands, or superstitiously imported cosmetics, and some cosmetics and even unknown ingredients, cosmetics contain antigenic substances (such as fragrances, preservatives, pigments, etc.), determine the part of the user inevitably have a chronic allergic reaction to it, and it is not easy to attract attention, often using a considerable period of time before the symptoms will appear . Avoid inappropriate use of glucocorticoids topical application: many patients with dermatitis symptoms for the sake of simplicity and convenience, the arbitrary use of hormone preparations topical application, because hormones have a strong anti-inflammatory effect, can make the symptoms quickly relieve, but because the skin barrier has not been restored, so soon after discontinued relapse, and therefore cause drug dependence, clinically known as hormone-dependent dermatitis. Avoid irritating foods such as onion, ginger, garlic, strong tea, coffee, alcohol and seafood fish, shrimp, crab, etc. The actual fact is that you will be able to get a lot more than just a couple of hours of work. It usually takes more than 3 months to fully recover from facial dermatitis, and the key to treatment is to completely get rid of the above-mentioned triggering factors. For acute flare-ups use anti-inflammatory creams such as aureomycin or erythromycin eye ointment, or topical moisturizing ointments such as urea cream, the simpler the ingredients the better. In the chronic period, topical medical skin care products that promote skin barrier repair are the main ones, as most of them do not contain allergy-prone substances such as preservatives and fragrances, and most of them contain moisturizing, anti-inflammatory and pro-repair ingredients such as hyaluronic acid, ceramide, collagen, jojoba oil, shea butter, avocado oil, licorice extract, red myrrh alcohol, and vitamin B5 (panthenol). In addition, it is very important to insist on cold and wet compresses during treatment, as follows: use cold boiled water or pure water, or mineral water, or distilled water, wet 6-8 layers of gauze or towels, or disposable compressed mask paper, or cotton, etc., pick up to not drip as degree, apply to the local dermatitis, 15-30 minutes each time, wet compress 5 times a day in the acute phase, 2 times in the chronic phase. More than 5 times a day in the acute period, 2 times in the chronic period, can replace the face wash, after 3 minutes inside and outside with skin care products moisten the skin. This can achieve the purpose of constricting blood vessels, relieving inflammation, reducing water evaporation and moisturizing. If accompanied by systemic symptoms or affect the daily life of workers, can be combined with drug internal or injection treatment, the specific need to find a dermatology professional physician interview.
