Acne : Common type of acne is called as acne vulgaris and commonly we call it pimples. It is more likely to occur during changes in hormones as in teenage, during pregnancy or near menstrual cycle. It is commonly seen in face, neck, back, shoulder and chest. Your skin is covered by tiny little pores which connects the surface of skin to underlying sebaceous gland which secretes an oily substance called “Sebum”. When this sebum is secreted in large quantity it blocks the pore and gradually forms pimple. It is tempting, but popping or squeezing a pimple won’t necessarily get rid of the problem. Squeezing can push pus and bacteria deeper into the skin resulting in more swelling and redness. In long run it leads to scar and might leave you with permanent scar. So, avoid popping or squeezing.
