How can i remove dark spot on forehead?

Mole? Hyper pigment?: It is impossible to tell if this is just color change from inflammation which can be lightened with peeling cream such as retin a (tretinoin) or a growth that would need to be removed.Since a dark spot may be abnormal have it evaluated.

Dark spot face: Best to see in person a derm or ps. You may need a biopsy so be aware of this possibility. If only pigmentation either a peel solutions or laser therapy could help remove.

Biopsy: Rather than thinking about removing it, make sure it is benign first. This can be done by seeing a plastic surgeon or dermatologist. A biopsy may be in order.

Few options: Skin lightner such as hydroquinone with ipl laser is the best combination.

IPL: Usually ipl (intense pulsed light), otherwise known as photofacial procedure works well for dark spots. Hydroquinone is a topical bleaching cream that works well also.

Depends: If it is simply sun-damage, some topical treatments or some laser treatments may a good option. However, if the lesion is concerning for melanoma, it needs to be biopsied. Melanomas are screened by the abcd's: a-asymmetry; b-irregular borders; c-different colors; d-diameber >6mm (size of pencil eraser). If you notice a mole with these characteristics, get it checked out asap.
