Struggling with body hyperpigmentation, is Naturium worth the hype or do I need something else?

Hi everyone, I’m a black girl that has been dealing with stubborn hyperpigmentation on my body for a while now. Specifically, my elbows, knees, and knuckles are noticeably darker, and my overall skin tone feels uneven.

I was about to buy the Naturium Glycolic Acid + Vitamin C body wash, but the reviews are completely 50/50. Some say it's a holy grail that faded everything, while others say it did nothing. I really don't want to waste my money on products that are not going to work.

I’d really appreciate some real advice
