Often, pimples, acne, rashes or inflammation leave the skin with dark marks. These blemishes, known as post-inflammatory hyper-pigmentation, may take a long time to fade and blend in with the lighter surrounding skin. 

These marks and blemishes may appear anywhere on the face and body. The marks cause unnecessary embarrassment and inconvenience to the sufferer. 

Such marks can take weeks, months or even years to fade and clear. The affected area may become more obvious and severe if the affected area is subjected to constant squeezing, agitation and use of inappropriate blemish products.
