All of a sudden from the past 6 months I have been suffering from few skin problems , intially it started with pimples and now pimples have come down , but rather suffering from dryness and redness only on cheeks , some have told me it could be rosacea . I wonder can rosacea happen only to cheeks , I dont have redness on nose , chin and other places . I am unable to understand whether its rosacea or just skin infection . please help me out
