I'm aware melasma is not one factor. Generally I'm told it's sun, hormones/progesterone, genetics but what about heat?

Sun and Melasma versus Heat

The sun is the single biggest cause of Melasma and best treated with Cosmelan.  Heat can make your broken blood vessels worse and V-Beam often helps this condition.  Best, Dr. Green

Heat and melasma.

We simplify the process of melasma by stating it is 3 factors only, however it is far more complex. For example, the relationship of thyroid factors, other hormones, and even receptors to blood vessels to the pigment cells play apart. The biggest contributing factor is UV, however heat can produce IR (infrared) radiation that can cause mottled pigmentation as well, - that disorder is called erythema abigne. Well known in the dermatology textbooks. To answer your question, pure heat along will not cause melasma, but may possibly be a contributing factor. Just did a recent search and nothing came up. Any other Dermatologist or Plastics have comments?CheersDr Davin Lim

Heat per se is not a risk factor for melasma. 

Melasma needs long term commitment with skin care and avoidance of skin factors such as sun exposure (Spectrase Sun Block) which has wide UV spectrum and SPF 30+ protection. 

Daily good habits with topicals may well help you chieve your goals with a good skin system like the Brightening Kit from KareSkin (see link). You may want to start with Melarase and Pigmentation Correction Complex. Scler-X from another vendor is for PIH relief (see link). 

Melarase AM is non hydroquinone based. 

Clear + Brilliant laser can be added once you start your pretreatment with topicals.

All of these are factors contributing to melasma. The goal is early treatment to prevent longterm stimulation of the pigment cells.
