SOS: laser hair removal burns on legs - 2 weeks later. Please help! Terrified of scarring! Advice? (Photo)

From your photo it does look like you have burn from the Laser Hair Removal.  The skin appears intact which is a good sign. The honest answer is it is hard to tell if this burn will cause a scaring or hyperpigmentation. Only Time will Tell. I recommend close follow up with the a doctor or surgeon who performed or supervised the Laser Hair Removal. The Dermatologist / Cosmetic Surgeon / Plastic Surgeons who perform or directly supervise laser hair removal have training and experience in managing complications like this.

Thank you for your question. Hormones create hair follicles and for the face your hormones are the strongest on the body.  Your hair grows in three different phases and it is required for you to have a laser hair removal treatment done every 4 weeks to catch the hair in the growth phase.   You will notice your hair thin out and the growth cycle slow down after each treatment. After the hair is completely gone after 6-8 treatments it is recommended to have a maintenance session done every 6 months to a year.  Please consult with a physican before having any treatments done . 

I recommend getting a consultation with a cosmetic dermatologist. Burns need a combination of:
1) healing lasers and light such as aerolase or laser genesis and LED therapy with light stim
2) topical growth factors, stem cells, antioxidants
3) oxygen facials
4) platelet rich plasma and A cell topically
5) sun protection
After 6-12 weeks you can treat for hyperpigmentation with cosmelan peels, hydroquinone, retinol or non ablative lasers like clear and brilliant or radiofrequency like venus viva. Best, Dr. Emer
 

Good news!  It doesn't look like you will be scarred.  The injured area is darker--which is actually a good sign.  That means the burn was not deep enough to kill the melanocytes, it really just irritated those pigment producing cells so they are spitting out more pigment.  If the pigment cells are destroyed you would be left with a permanent white spot.  The big question is how long will those cells take to settle down after everything is healed up.  If they calm down right away (which the cicaplast is probably helping them to do) the pigment will fade as the skin cells turn over and it may take only 1 to 2 skin cycles (6 to 12 weeks) to lighten up.  If the pigment cells 'hold a grude' and stay irritated it may take longer.  Usually the darker your skin base the more stubborn the cells are, and the longer it takes to lighten.  On the off chance that these cells are permanently hyperactive there are prescription creams that are effective at lightening the area.  At your next appointment discuss the possible future need for a prescription cream with your doctor.
Hope this all make sense!  Best regards,
Dr. Amy
