Is Hyperpigmentation After Laser Hair Removal Permanent?

Hyperpigmentation after laser hair removal usually is not permanent.  It’s better for your doctor or dermatologist to evaluate your skin first, but the majority of the time, it is transient.  Using sunscreen on a consistent daily basis and staying out of the sun helps.  Other things that will help with hyperpigmentation are bleaching agents such as hydroquinone like Obagi #3 and Retin-A, but make sure you have a physician evaluate your skin condition to make sure you are treating it with the correct products. 

Fortunately, hyperpigmentation is not permanent in most cases.  It is a result of your skin producing more melanin in response to the heat from the laser.  Your body will work to restore homeostasis and the pigmentation will fade. Protect yourself from the sun to prevent the dark areas from getting worse. Talk to your dermatologist to see what topical  treatments might be appropriate. 

Typically hyperpigmentation following laser hair removal is temporary and resolves within 4 to 6 weeks. It may be helpful to use low dose steroid creams and bleaching creams to hasten resolution since yours has persisted but I would discuss with your treating physician.
