It's been three months, and I'm already starting to see results. One day, while doing my makeup, I noticed that the spots I typically conceal were lighter. I was shocked, but then I remembered the only change to my routine was Ammu, and that it must be the masks working. The spots were so much lighter that I didn't have to use as much concealer. I've tried other products in the past, but nothing has given this type of result. Nothing! I will be repurchasing for sure.
