From a sunburn to an allergic reaction, there are many situations in which your skin can become red or irritated, starts as redness on the cheeks, nose, chin, or forehead (and less often on the neck, scalp, chest, or ears). If not treated, pimples and bumps develop and the nose might become large and bumpy as tissue builds up. Getting treatment is a must,so make sure you see your doctor. If you don’t take care of your rosacea, redness and swelling can get worse and might become permanent. http://www.healthmister.com/2017/11/what-causes-redness-of-the-skin-rosacea/
