Spring is here and it is soothing to watch the spring colors, but some of our fellow women may be facing or suffering from facial allergies. Today, we will talk to you about how to prevent facial reoccurring dermatitis and how to treat it once it occurs. Facial reoccurring dermatitis occurs mostly in women, and the cause is not well understood. It is clinically associated with the use of cosmetics and light stimulation, and is prone to occur in spring, which is considered to be a synergistic effect of cosmetics and pollen allergy. The onset of the disease is sudden, and the main manifestation is light or dark red spots on the face with mild swelling, accompanied by fine bran-like scales. Repeated attacks can leave pigmentation and itching. Treatment can be done with antihistamines for internal use and moisturizing creams with simple non-irritating, anti-inflammatory and anti-itching effects for external use, with negative ion spray for better effect. During the treatment period, please refrain from using cosmetics and alkaline cleansers and eat less irritating food to help the recovery of dermatitis and prevent recurrence. For those with previous facial re-dermatitis, try to apply the simplest moisturizer to your face and wear a wide-brimmed hat for sun protection when you are outdoors in the spring. Once the onset of the disease, it is important to seek medical attention as soon as possible.
