Hi - I just wanted to share with you my 'cure' for melasma. My partner and I recently moved to Tenerife. I have very bad melasma on my upper lip and upper right arm. Since we moved here I have discovered the aloe vera leaf. I have been applying the gel from the leaf morning and night for the past week. The melasma on my upper lip has gone completely and the melasma on my upper arm has started to fade gradually and looks a 100% better than it did a week ago. I used to hide my arms but now I'm wearing short sleeved tops which I never, ever thought I'd wear again. You need the actual aloe vera leaf. Cut a slice off the leaf and slice it open to reveal the gel inside. Rub this on your melasma morning and night and it's really like a miracle the melasma fades gradually. I don't think aloe vera gel in a bottle will work alone as it's not pure aloe vera gel. The plant grows abundantly here on Tenerife but I'm told you can buy it in health food markets or online.. Good luck to you all.
