I am getting dry red swollen patches under the eyes.. I dont use any facial creams or makeup ! Everything was normal but suddenly I have first developed a red dry patch under my right eye and I thought it must an allergy and before sleeping I applied Vaseline but when I got up in the morning I saw the patch turned to be turning black and more dry and it has started sweeling and I am even getting a burning sensation near it and it has slowly started to infect my left eye.. Why am I getting this ?? and Kindly suggest me like how to eradicate this!!!!
