Works for me
Color: Picotonic Shot
My skin loves this stuff. I haven’t had a pimple since I started using it and my skin looks more even and it’s fading red spots. I highly recommend giving it a try!

A bit sticky but tolerable
Color: Picotonic Shot
I have both Dr. Melaxin peel shots in black and white rice and saw immediate improvement in the removal of tiny blackheads trapped in tight pores on my nose and around my lip line. It might honestly not get in very deep but it at least helped my skin, everyone is different. I thought my face could never be that improved by anything other than squeezing the crap out of my face and still getting nowhere. So I thought I'd try more of the product line. With this particular product I'm still too new to judge much but on my particular skin it is a bit sticky so I'll use it at night. I wash with the Dr. Melaxin Melting Cleaser, the Cactus toner, then the Dr.Melaxin Cemenrete Cyano Pink Spicule Serum and then this product. I'm 57, I don't have acne issues but I do have a few hyperpigmentation spots if like to fade out a bit if possible and just improve the overall cleanliness and look of my skin.
Nothing is a miracle but it's been a noticable improvement so far. I give it 4 stars primarily due to it being kind of sticky on me. One drop goes a long way FYI.

It works!
Color: Picotonic Shot
Love this product!!! I have been using it about 10 days now, and the brown aid spots on my face are down by half, I am absolutely amazed! I did not take before and after pictures, just because I was waiting for it to work on the wrinkles, I had no idea it would work on the brown spots!! Highly recommend this product!!

My second bottle!!!
Color: Picotonic Shot
Wow this stuff really evened out my skin tone. My face looks brighter and tanner which I need and the best part is I don't have to go into the sun to do it. People have asked me if I just got back from vacation bc my skin tone. It gives a nice glow as well.
This is my second bottle
