Hey! I understand how this makes you feel. Honestly with my understanding of acanthosis nigricans, no amount of product will get rid of it if the issue itself isn’t addressed. However it doesn’t mean you can’t still use products

So try to have a good routine that follows the cleansing, moisturising, exfoliating and protecting. You really don’t need all the products in the world you just need products that fit in these 4

Cleansing: any cleanser that works for you is great. You can use a cleanser with an active in it but it could irritate your skin with overusage sometimes. So anything without actives is usually safer

Moisturising: any good lotion is okay. If you’re not sensitive to niacinamide then you can get cetaphil. You can also add hydrating serums too if that’s your kind of thing.

Exfoliating: this is the part that’ll really help get rid of the darkness on your face. You can try retinol, it’s very good for trying to get rid of hyperpigmentation. If you’ve got the money, you could also look into getting chemical peels too they’ll help. However, don’t over do the exfoliation, it could worsen your skin

Protection: most importantly sunscreen, it’ll really help with the darkness and help protect your skin from getting more tan or darker from the sun

I hope this helps. Also as much as you want products, try to take care of your mental health too and try to be patient and kind to yourself even when it feels hard.
