If you don't find buying from ebay or amazon comfortable, or you can't find Kojie.San, then I highly recommend this face wash:

It's by Doctor's Dermatologic Formula and cost's $35, it's a bit pricey but it's the first cleanser that I actually found to be helpful with hyperpigmentation. I usually think lotions work better since you keep it on, but this cleanser is amazing, and it's not that harsh. It has glycolic acid, salicylic acid, licorice, and kojic acid. Although, it does have fragrance, so if you're allergic to products containing fragrance, then this might not suit you.
