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.
Causes of acne:
1. Oil production
2. Bacteria overgrowth
3. Plugged pores
These three things interact to cause inflammation resulting in pimples that may be cystic (hardened under-the-skin), red, swollen, painful and filled with pus.
Types of acne
Comedonal: Pimples that are dried, not red, and you can see either whiteheads or blackheads. The comedones can get steamed then extracted using a metal extractor. They respond best to Retin A and Benzoyl Peroxide. This will keep the pores clean and minimize the number of blackheads and whiteheads popping up.
Infected: Usually red, painful, inflamed, and may contain pus, which means there is a large amount 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 of acne. Blue light or laser genesis can also vaporize the bacteria and lighten up the pigmented scars.
Cystic: This type of acne will form nodules that sometimes burrow deep into the skin. They form as a result of an enclosure of infected acne underneath the skin. They tend to heal by “eating” away at the skin.
Truncal: These are 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.
