Does Halo cause melasma?

HALO does not cause melasma, that is s skin condition you already have.  Any laser treatment can create worsening of melasma if proper prevention is not used.  In fact,  HALO Pro can be used to treat melasma.   Be sure your plastic surgeon knows of your previous melasma.  You will need bleaching cream before and after, absolute sun avoidance and sunblock.  Do this with an experienced physician.

A HALO treatment will not cause melasma.. Unless it’s done improperly by an unexperienced provider. HALO Pro can actually be used to treat melasma-- just make sure that your provider knows about your skin history and proper precautions are taken. Also, be aware that BBL treatments can bring out melasma, so when considering other laser options be very clear about your skin history with your provider! Good luck!

Melasma can be improved with topical lightening treatments, chemical peels, and lasers. Too much heat from any treatments could make the hyperpigmentation worse. It's best to have a consultation to go over what the best treatment plan is for your skin. 

The ablative erbium component can temporarily IMPROVE melasma, however rebound is often seen. It does not cause melasma but the heat from the erbium laser (and to a limited extent the non-ablavitve component) can increase pigment production. Melasma responds better to QSL or gentle lasers that shrink down the 'arms' of the pigment producing cells. Melasma should be managed by treating all aspect of this condition- SPF and hats to reduce melanin production, tyrosinase inhibitory creams, lasers, and T.acid to modulate the VEGF or vascular component of this chronic condition. Laser is not the only answer to this complex skin condition. For more on melasma management, please go to the web reference. Dr Davin Lim. Laser dermatologist. Brisbane.
