(Purchased with my own money) Luna Concealer

I'm really worried about my melasma these days. I should have managed it early on, but I missed the timing, so foundation alone isn't enough to cover it. I absolutely have to use concealer, and since this is a liquid type, it's easy to apply and provides decent coverage, so I'm using it. However, I need something that works even better. I wish my melasma would just disappear.
