there are options with lasers and lightening creams to remove scars on the forehead. Please see an expert. Best, Dr. Emer.
Thank you for your question and photograph. It appears that you developed a case of postinflammatory hyperpigmentation as a result of your pimple and I would recommend a lightening cream containing hydroquinone as well as a sunblock with either titanium or zinc to protect this area from the sun's UV radiation. It should improve in appearance over the next several month.
The most common treatment for this is called IPL- Intense Pulsed Light- or "photofacial". It uses several wavelengths of light energy to coagulate the abnormal pigment, which you will then shed. IPL is fairly easy to find as it has been around for many many years. It may require more than one treatment but it is very effective. It is found at medspas, plastic surgeons and some dermatologists offices...

I would use a procedure known as Focal Hyfrecation (FH) to help resolve the area of concern, followed by application of Plato's Scar Serum.
