Is hyperpigmentation from HALO laser permanent? Do I need to treat the hyperpigmentation and if so what treatment(s)? (Photos)

Thanks for the question and sorry you're going through this. The first thing to do is to call your doctor's office. He needs to know what is going on as he's the one with the records of the settings used and will have before as well as after pictures to compare.From there, the office is likely to start you on very strict sun avoidance and physical blocks (scarves, hats and zinc or titanium containing sunblocks). The addition of prescription strength hydroquinone, kojic acid and occasionally retinols usually make a huge difference as well. Well managed, it is very unlikely that your post-laser pigment won't resolve.

Was pigmentation there before HALO, if so, one needs to identify the TYPE of pigmentation. HALO is designed as a low downtime laser to treat sun spots, sun damage, and freckles, as well as provide overall skin rejuvenation. The flip side is that it can make melasma pigmentation worse. If this is melasma, medical treatments should be incorporated along with lasers (NOT HALO), but other methods like nano or pico lasers. See you plastics for advice. HALO may also have un masked the underlying melasma. All the best, Dr Davin Lim
