A brown spot is growing or changing shape. Can I fade it?

Please have a clinician assess it before treating it as a cosmetic dark spot. A cosmetic brightening plan should wait until a changing lesion has been medically evaluated.

A changing brown spot should be assessed before you fade it

A change in size, shape, or colour needs attention, and an online answer or photo cannot rule out a concerning cause. I would not recommend a brightening product first.
