What are the types of acne, and how do they differ in severity?
Acne includes blackheads, whiteheads, inflamed small bumps and pustules, as well as deeper painful nodules. Several types may coexist. Deeper lesions increase the risk of scarring, but scarring is not inevitable.

Superficial and deeper lesions
Blackheads and whiteheads arise from blocked hair follicles. A blackhead’s dark colour does not mean the skin is dirty. Papules are small inflamed bumps, while pustules contain pus. Nodules and cyst-like lesions are deeper and may persist longer.
How treatment is selected
Assessment includes lesion type, number and location, existing scars and emotional impact. Counting spots alone does not capture severity. Topical treatment may suit some cases; more severe acne may need a different plan. Do not start antibiotics or isotretinoin merely because a spot resembles an online photograph.
Reducing avoidable damage
Avoid squeezing and harsh scrubbing, and use gentle products. Seek dermatology advice for painful deep lesions, developing scars or acne that is not responding to appropriate treatment. Early assessment helps address inflammation and discuss marks without promising that every mark will disappear.
