Redness on the sides of the nose may be caused by UV exposure, cosmetic irritation, and rosacea. It can be treated by strengthening sun protection, giving appropriate medication, and physical therapy.
1. Ultraviolet radiation: Prolonged exposure to ultraviolet radiation may cause symptoms of redness on the face. You should pay attention to skin moisturizing, go out to strengthen the sunscreen, do not eat spicy and stimulating food, and increase the intake of vitamins and proteins appropriately.
2. Cosmetic stimulation: the use of irritating skin care products may lead to local redness. It is recommended to stop the use of cosmetics, oral loratadine, cetirizine and other antihistamines, if necessary, with cold spray, ice packs, to promote capillary contraction.
3. Rosacea: If the redness is obvious and does not subside for a long time, it is considered to be related to rosacea. Antibiotics such as fusidic acid and metronidazole can be used externally, which have antibacterial and anti-inflammatory effects. It can also be treated with intense pulsed light and pulsed dye laser, which can reduce capillary dilation and proliferation, and also inhibit sebum secretion.
It is recommended that patients go to the dermatology department of the hospital to clarify the cause and choose the appropriate medication or physical therapy treatment under the guidance of the doctor.
