I'm 23yrs old (female) and never had major problem regarding pimples. My face used to be clear always, except for a pimple once or twice in a month. But, since the past 2 months, few small pimple-heads popped up on my 'forehead' and formed into a cluster. These are flesh-red, and I feel the pain, if I even touch them. I'm afraid of using chemicals on my skin. Please suggest me home remedies to get rid of these pimples.
