Acne is a relatively common condition which tends to affect areas of the face or body with the densest sebaceous follicles, i.e. the face, chest and back.
These three things interact to cause inflammation resulting in pimple that may be cystic (hard underneath the skin pimples), red, swollen, painful and filled with pus.
Comedonal: Pimples that are dried, not red, and you can see either the white heads or black heads. The comedones can get steamed then extracted using a metal extractor. They respond best to Retin A and Benzoyl Peroxide. They will keep the pores clean and keep the number of blackheads and whiteheads down.
Infected: Usually red, painful, inflamed, and might have pus. That means there are lots of bacteria inside. When these heal they tend to leave behind “PIH” or pigmented scars of red, or brown discoloration. Either topical or oral antibiotic is good for this stage. Blue light or laser genesis will vaporize the bacteria and lighten up the pigmented scars.
Cystic: They form nodules and sometimes the nodules burrow deep into the skin. They form as a result of enclosure of infected acne underneath the skin. The ones underneath the skin or cystic acne tend to heal by “eating” away the skin.
Truncal: Pimples that affect the back or the chest. They usually appear as small red and pus filled bumps. They often leave large brown spots (scars) all over the area.
