I have really stubborn pigmentation on my face. That’s from years of travelling in hot countries without properly protecting my skin 
My face looks like a world map :( I had 5 microdermasion treatments in the last few months. They reduced the pigmentation a bit, but my face is still far from clear. I’ve been religiously using spf 50 suncrean.
Is there anything else I can do? I hate to give up.
