What can I do to get rid of this wax burn scar? (Photo)

Melarase creams work well for this discoloration. Start with Melarase AM, Melarase PM, Melapads, and Replenish creams. Best, Dr. Karamanoukian#Realself100 Surgeon

Your pigmentation after 2 years suggests ongoing stress to the deep dermal layers that will cause your skin to deposit more melanin and get darker with sun exposure.  Genetic skin type plays a huge role in why the pigmentation is so persistent.  Use of topical antioxidants and other modalities such as cold laser treatments can help the deep dermis to resist photonic stimulation.  Consult with your dermatologist or a specialist plastic surgeon for additional recommendations to control the pigmentation.

Thanks for your question and posting a picture.  The dark spot look like you have post-inflammatory hyperpigmentation (PIH).  After a personal consultation, we would probably recommend the PicoSure Laser with the FOCUS and/or Flat Lens for pigment correction.  The FOCUS lens also works well on scar reduction.  PicoSure is safe for all skin types.  Depending on the severity of the pigment, it will probably take 1 to 4 treatments.  Best of luck.
