Acne and Its Aftermath: From Diagnosis to Treatment and Scar Prevention
Acne is not one problem, and not everyone needs the same product. The right starting point is to define how inflamed the skin is, the type of lesions, whether there are marks or scars, and the factors that change the plan, such as pregnancy, medications or a hormonal pattern. This page brings together a clear path from treating active breakouts to dealing with marks and scars, instead of jumping between scattered treatments.

The medical map
Define the problem and its pattern before choosing a product, medication or device. Then move to the specialised guide.
Treat activity before scars
If acne is still active, controlling inflammation and preventing new lesions usually comes before any cosmetic plan for scars. Treating scars while inflammation continues means repairing the old damage while new damage is forming.
Tell a mark from a scar
A brown or red spot after a breakout is different from a depressed scar. Color can improve with protection and topical treatment, while structural scars such as rolling, boxcar and ice-pick scars need assessment and different procedures.
The strongest treatment is not always the start
Isotretinoin, hormonal treatments and procedures each have a specific place. The choice depends on severity, pattern and risks, not on how well known a drug or device is.
