No Good
So I got this under the impression by the videos online that this was really concealing under the eye and it’s not…very oily and hasn’t done anything for under my eyes at all! Scam!

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!

Melaxin
Set name: KOJIC, Set name: KOJIC
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.
