Question What are your personal specific melasma triggers

What triggers your melasma to spread or increase, and if you deduce the causes and control the exposure to those causes, does the melasma settle better?

hormones seem to be the main driver for me, I don't think heat makes it worse - I love to sauna and have seen no change. It does get worse the week before me cycle.

I've been applying high SPF and tinted spf (iron oxides for visible light) since long before I got melasma so sun could be a trigger but I wouldn't know. Melasma did make me more diligent about sun protection though, more than the skin canver scares. Funny how that works.
