I would use a combination of Plato's Scar Serum and Melarase PM followed by Clear and Brilliant laser.
Your skin is only very recently irritated and inflammed from the wax. It is too early to attempt any treatments while you heal as they can make your inflammation worse. It is best to allow your skin to recover on its own and protecting it with a skin protectant such as aquaphor and SPF to avoid UV damage and hyperpigmentation. If you continue to have hyperpigmentation after you skin heals in the next few weeks, you can consider additional energy-based treatments such as lasers or IPL or topical therapies such as bleaching cream, but it is more likely that your skin will heal well on its own. Hope this helps.

Silicone based scar gels may help improve healing. If dark pigmentation persists after healing it can be improved with lasers, microneedling, peels, and skin care. I suggest using skin protection and avoiding sun exposure to this area. Please see an expert for treatment. Best, Dr. Emer
