This needs to be seen by a Plastic surgeon or dermatologist to minimize the long term risks. Most likely course is that the areas will be initially lighter than the surrounding pigment and possibly scar and/or become hyperpigmented. It is hard for me to make recommendations without seeing you. This is not normal. Either improper settings were used, the wrong type of laser, or improper use of the laser is at fault. Other causes are recently tanned skin can cause this.
Hi thanks for sharing your concern .it is superficial first degree burns,may be induced by improper laser settings and a tanned skin.it needs treatment with a short course of topical steroids and a good moisturiser.during your next sitting adequate precautions is absolutely needed to avoid a longterm hyperpigmentation .please do consult a board certified dermatologist and get treated.
I think it is important that you talk with the clinic that did your laser hair removal. If you were tan on your thighs that can account for the different reaction to the laser. Time will reveal the final outcome. Please choose an expert for your laser hair removal.
Its hard to say if this is burned or starting to become hyperpigmented. you want to see a board certified dermatologist to evaluate, it could end up causing whitening or darkening and needs to be watched closely. Best, Dr. Emer.
