What causes facial allergies in women?

Generally, facial allergies in women may be caused by improper use of skincare products, ultraviolet (UV) radiation irritation, contact dermatitis, seborrheic dermatitis, or steroid-dependent dermatitis. It is recommended to seek medical attention promptly, identify the underlying cause, and undergo symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Improper use of skincare products: Frequently changing skincare products or using those containing alcohol or fragrances can irritate the skin barrier and trigger allergic reactions. Immediately discontinue suspected products, choose simple-ingredient medical moisturizers, and avoid makeup in the short term to reduce skin burden.

2. UV radiation irritation: Inadequate sun protection leads to excessive UV exposure, damaging the skin barrier and causing allergy symptoms such as redness and itching. Apply sunscreen with SPF 40+ and PA+++ when going outdoors, and use umbrellas or hats for added protection. Avoid prolonged outdoor activities during peak UV hours.

3. Contact dermatitis: Exposure to allergens such as cosmetics, metal jewelry, or pollen can trigger facial allergies, manifesting as redness, swelling, and papules. Patients may follow medical advice to use medications such as cetirizine hydrochloride tablets, loratadine capsules, or calamine lotion, and completely avoid the identified allergens.

4. Seborrheic dermatitis: Overactive sebaceous glands combined with microbial imbalance can lead to facial allergies, presenting as light red patches with scaling and itching. Patients may use medications such as tacrolimus ointment, pimecrolimus cream, or vitamin B6 tablets as directed by a physician to regulate skin inflammation.

5. Steroid-dependent dermatitis: Long-term use of corticosteroid creams or steroid-containing skincare products can increase skin sensitivity, leading to allergic reactions such as redness and itching upon discontinuation. Under medical guidance, patients may use recombinant human epidermal growth factor gel, hyaluronic acid gel, or mucopolysaccharide polysulfate cream to repair the skin barrier.

In daily life, wash the face with lukewarm water and avoid soap-based cleansers. Maintain a light diet, reducing intake of spicy, irritating foods and seafood. Keep a regular sleep schedule, avoid staying up late, and engage in physical exercise to promote blood circulation and enhance the skin’s natural resistance.
