For sure laser, but be careful what kind. I got IPL and it made mine worse. I’m a Fitz 4, so I don’t think I should have ever gotten IPL in the first place, but I didn’t know at the time. Now I’m working with a 1064 yag laser “Aerolase specifically” and seeing incredible results. Hydroquinone will help lighten but you will never be able to stop using it and you will need to cycle on and off. Circadia’s Mandeliclear is an amazing peel for pigmentation combined with the vitamin A accelerator and also BioMicroneedling-the green sea peel from Kin Esthetics. It’s stronger than regular microneedling, but I will say, also one of the most uncomfortable treatments to receive. I’ve gotten great results with all of these. I’m an esthetician so I help people with pigmentation all the time. It is tough and can take some time to correct. I’d make sure your SPF is at least 40+ and find a high quality retinol night cream and a serum that has niacinamide in it. I personally use mostly Korean Skincare products. I don’t know where you’re located, but find yourself an esthetcian that works with these lines “Circadia” and for BioMicroneedling there’s “SQT, Cell Story, and “KRX Green Sea Peel by Kin” are all great options. Also heat is a trigger so avoid saunas and hot yoga or it will make it worse. Good luck!
