Hyperpigmentation is the bane of my existence! My skin is SO prone to it too, the tiniest spot will leave a dark spot that will take weeks or months to fade. It is the reason why I am always shouting about sunscreen lol because it’s one of the ways to protect and prevent it from getting worst.
I’ve tried a TON of products for hyperpigmentation and I have learnt whilst it’s important to fade the dark spots, it’s more important to prevent them from happening (triggers that are in my control) and skin barrier health is also important.
I do want to start getting clinic treatments soon but for now, I’m happy with treating it at home
A word- hyperpigmentation is difficult to treat so please do not get frustrated if it seems nothing is working. Almost everything is a trigger: heat, sun, acne, inflammation etc, so be patient!
Key to hyperpigmentation is sunscreen! Finding your triggers and prevention (this is above my pay grade lol please go to a professional) but I can share products/ingredients I have used that have helped mine

I have a separate list for sunscreens- view this here
This will be a growing list so keep checking for more
Paula’s Choice Treatment serum
The Body Shop Brightening Drops
Medki8 Crystal Retinal 10 (I found 20 to be more effective but this is on professional advice only & in clinic. You also have to build tolerance to it! Please don’t start on retinal 10 if you have never used retinol before)
Good Molecules Discoloration serum
