What to do about dry and red skin

1. Skincare adjustment: Use moisturizing skincare products with good hydrating effects, such as collagen gels and hydrating face masks. Whenever possible, choose medical-grade products (labeled with medical device registration numbers) to ensure safety and effectiveness. 2. Improve daily habits: Avoid sun exposure; in principle, refrain from wearing makeup; avoid contact of the skin with high-temperature objects; and avoid touching or scratching the skin with unclean hands. 3. Medication treatment: If dryness and redness of the skin are caused by an allergic reaction, oral antihistamines such as promethazine hydrochloride tablets or cetirizine hydrochloride tablets may be taken under a doctor's guidance.
