Although some alternative health practitioners recommend home remedies such as vitamin K, oregano oil and colloidal silver to treat rosacea, there is not significant evidence of their effectiveness as of 2015, according to Mayo Clinic. One of the best at-home measures patients can take is avoiding substances that trigger flare-ups.
Patients can lessen their chances of experiencing rosacea flare-ups by refraining from using alcohol-containing products on their faces, notes Mayo Clinic. It is also helpful to protect the skin with sunscreen in the summer and with a scarf or ski mask during the winter months. Additionally, patients who wear makeup can make any skin redness less noticeable by wearing a foundation that contains green tints.
