also, a year ago i got acne on my chest which i had never had before but now it has juts scarred my skin lightly.
however, the acne on my face is still ther. i have large red spots ussually severla of them together and they are always filled with white stuff.
also, i have noticed that they occur where hair grow out of.
i have tried many medication such as panoxyl, zineryt and antibiotics but they dont seems to worl. they dry my skin and it become irritaed. do u have any remedies which will help me. thank you.

The white stuff is probably pus, like from a whitehead or blackhead.  Have you tried the OTC stuff like Clearasil, Stridex or Neutrogena?  The benzoyl peroxide cream works well, and the salicylic acid pads.

Also ,  be careful what soaps you use.  I use only Cetaphil on my face.
