Acne usually appears on the skin areas with most oil glands. It takes many forms, discussed below:
Non Inflammatory Lesions
Whiteheads and Blackheads – Together called comedones, these are formed when the hair follicle openings get blogged with oil, dead cells and bacteria. Comedones opened at the surface of the skin appear dark, therefore called blackheads. Comedones closed and slightly raised are called whiteheads.
- Pimples (pustules) – Tender, red bumps with light colored pus near the tips.
- Papules – Tiny, raised bumps with infection at the hair follicles. They are tender and red too.
- Cysts – Pus-filled and painful lumps formed beneath the skin surface. They are boil-like infections.
- Nodules – Solid, large and painful lumps formed beneath the skin surface. They are formed due to secretions accumulated deep within the hair follicles.
