Does anyone know of any skin lightening products that actually work?

ok so heres the deal. im a teenage guy and ive had eczema for a while. it seems that everytime i scratch or something it leaves a lot of dark marks all over my body to the point where its consumed a lot of my body. these marks are everywhere imaginable and it really pisses me off. Now ive tried store products like palmers fade cream, which contains an ingredeitn called hydroquinone, but unfortunately it doesnt work for me. Ive also heard that lemon juice is a good way of eliminating these dark marks, and frankly, ive tried that for a while too. i went to a dermatologist and they said the only thing i could do is wait, but i really dont wanna wait another few years for that, because it really ***** with me and it inteferes with my self confidence. so i guess my question is: does anyone know of any skin creams out there that can help, or perhaps some sort of home remedy of some sort that has worked for other people. please, ive been dealing with this problem for years now and i feel like theres just no hope, does anyone have any suggestions besides the hydrquinone or lemon juice thing?
