How do I lighten/remove dark mark from ingrown hair on breast? (Photo)

Thank you for your photo. After an ingrown hair, it possible to have an area of wound healing and a small scar. Usually there is no actual scar at all, but just a dark spot from inflammation. These spots usually improve on their own if you protect them and keep them out of the sun. If the scar or post-inflammatory hyperpigmentation remains, a variety of treatments can be performed from bleaching creams to  energy-based lasers and radiofrequency devices to mechanical disruption of the scar with microneedling. For the best treatment options, it is important to visit an expert for an in-person examination. Hope this helps!
