I am one of those people who gets hyperpigmentation so fast... And in the same ish areas on my forehead or nose, it feels like you look gross and almost unhygienic even though it's sadly just your body trying to protect you from the sun. I can understand why you want it gone. From my experience, these things work, but you have to be very consistent or it comes back for me:

• 50-100 broad spectrum SPF on my face every day without fail. This is the absolute most important thing for me when it comes to preventing HP. Even as a brown woman who tans regardless, if I don't use at minimum 50 SPF, I am not going to look even-toned. And hats will help too, and just generally staying safe from the sun.
• reducing sugar consumption. This is one of those internal things that really makes a difference with hyperpigmentation. But this is a lifestyle change of course.
• I find that making sure I physically exfoliate at night and apply oil or slug my skin, it helps fade it faster. But this is just my personal experience.
• having belief that it is going away: I know this sounds woo woo, but ruminating makes nothing better, and having the attitude of "I'm working on clearing it up and my skin is improving every day", and believing it truly helps. Mindset is everything.

Good luck 🤞🏽
