Laser on Chest Burned Around Nipples. Permanent Scarring?

Most of the post laser treatment complications involve blistering and pigmentary changes. Unless it stimulates vitiligo (permanent depigmentation), most pigmentary changes will slowly fade with time. Hypertrophic scarring can be made better with topical and/or intralesional cortisone injection. Evaluation and management by an experienced board-certified dermatologist is critical in this situation.

Unfortuantely there is no description of the type of laser, its energy settings, what it was used for, your skin type, and the wound description (if there is any). Many times lasers induce temporary color changes which are not scars. If you have a concern you must see your doctor who treated you, and quickly so that if there is a problem, it can be addressed before a scar does form. If it is just temporary color change, some creams that your doctor may prescribe can help.

Hi SF.  It is not possible to know from the description whether burns from laser hair removal will be permanent.  We would suggest that you demand proper after care instructions from your practitioner to ensure proper wound healing.  

Beyond that, we would suggest that if you consider laser hair removal again, you research the safest and most effective laser for your skin type as it is very common for practices to attempt to use one laser for all skin types.  This is a mistake.  Good luck.
