Best product I have found!!! Love love love it!!
Color: Picotonic Shot
This product
And all the other dr Melaxin products are awesome. I have seen visible changes in my skin and my forehead wrinkles or creases if you will have diminished. I have to creases in my forehead and one between my eyes and ai can’t even see that anymore and he one on my forehead has lightened up and is not as prominent. My skin is visible plumper I am 49 and look like I am maybe 38. I have probably spent thousands of dollars on all kinds of beauty products and none work like these!! Definetly purchase hem I just bought my second bottle. I have only been using this for three months and it deminished the wrinkles in that amount of time. Also get yourself the spicual shot as well it is the pink one it's a micro needling serum and you don’t feel tingly and you don’t get red irritated akin like you do with other micro needling products. Definitely buy all their products. If you do I would get their set of skin care with the serums the cleanser, the turmeric exfoliator,therice exfoliator that is awesome all you do it put a few drops where you have black heads and you rub it into your skin in circles and it pulls out the black heads and exfoliates at the same time. I will never buy another product again their entire beauty line is great they have all you would need for beautiful skin.

Brightened My Skin and Helped Dark Spots
Color: Picotonic Shot, Color: Picotonic Shot
I’ve really liked using the Dr. Melaxin Protonic Shot Serum! The bottle is pretty small, and since I used it twice a day it lasted me about 4 months. But one pump is enough for my whole face. My skin feels very smooth after using it, and I’ve noticed some darker spots becoming lighter over time. I’ve also seen a brighter look under my eyes, which has been a huge plus for me!
