This stuff works! I'm using M+ because my melasma is stubborn. I used the same formulation a year ago with 6% HQ. This one is stronger without the expensive dermatologist bill. I see a noticeable difference in 30 days. Be diligent about sunscreen. Physical barrier sunscreen that's >30 SPF, several times a day. Even inside, because melasma is sensitive to UVA, UVB, and visible light.
