Two common home remedies for rosacea are diluted white vinegar and green tea soaks, according to MedicineNet. One solution is to mix one part regular vinegar to six parts water, then use it to wash affected area twice daily. Vinegar is a natural disinfectant and may reduce bacteria on skin.
Because vinegar may cause a renewed flare of rosacea in some people, MedicineNet recommends testing a small area first. Another option is to soak the affected area with green tea, which may have anti-inflammatory properties. It is important to follow a good skin-care regimen, cleansing twice daily and applying sunscreen with an SPF of 50 or higher. Depending on the symptoms, a dermatologist may prescribe an antibiotic to put on under the sunscreen.
