It smells good, but the pump doesn't work. Had to change it out with another one I had. Also a bit expensive as to can buy it for less and a store such as Walmart.

There is a reason why this went viral!
Set name: KOJIC
This works wonders. I went with a sand and stone deodorant, while it gets the job done,it makes my armpits dark. With this stuff, it takes care of my pits and keeps them looking nice. Also great for scratchy feet. Keeps them soft and healthy. Will be purchasing again!

I’ve been using the Melaxin Body Keratin Care Kojic Acid Turmeric treatment, and I’m honestly impressed with how it has improved my skin texture and tone. This product combines kojic acid and turmeric, which are known for helping brighten the skin and reduce the appearance of dark spots. It also contains keratin and other nourishing ingredients that leave my skin feeling soft, smooth, and hydrated.  After a few uses, I noticed my skin looked more even and radiant, especially in areas like my arms and elbows. It gently exfoliates and helps remove dead skin without causing irritation, which is great for sensitive skin.  The formula feels lightweight and easy to apply, and I love that it can target hard-to-reach areas depending on the format (spray or serum).  Overall, this is a great body care product if you’re looking to brighten your skin, smooth texture, and get a healthy glow. Definitely worth trying!

Life saver for your skin
Set name: KOJIC
I was skeptical before buying this. my skin dries out so quickly and lotions is just a temporary fix for dry skin. I was amazed that the first time I used it all the dry skin was peeling off such a simple solution. I’ll never be without it now you have to try it to believe it.

Good product
Set name: KOJIC
I have used 1/2 bottle since December. Easy to use on dry skin, I use it before showering. I Probably don’t use it enough, simply because I forget. I have had dry peeling skin on my forehead recently and thought, oh I should use it there. I have to say, it made a big difference. One use and the dry skin came off and my forehead looks much better. I was having a hard time with makeup looking splotchy and now it goes on smooth.
