Products such as..?
Apparently Kojic Acid is very unstable in products and loses it's efficiency quickly when exposed to air/light, so they often use 'kojic dipalmitate' instead. "However, there is no research showing kojic dipalmitate to be as effective as kojic acid"
I had that issue because I was using a very expensive product a year ago that used Kojic Dipalmitate when I thought it was the same as Kojic Acid. Forgot the name, and it barely worked if at all. That's when I started looking at the ingredients more often, especially for these "lightening treatments".
I'm currently using products by
Kojie San, mainly their face creams for facial scars and their body lotion for body imperfections. I don't think there are any markets right now that sells them outside Asia. One of my Filipino friends actually recommended it to me and I had to search around ebay and amazon just to find it.
I've been using it for a while, and it has worked, much faster than products with that dreaded
Hydroquinone. Although I can't say it enough, the facial creams are for people who don't have sensitive skin. The lotion is very soothing. I'm looking at the bottle right now and so far I think it's oil free so I guess you can use it on your face also.
They also have a kojic soap that I tried and it was terrible. I mean, it worked at what it was suppose to do, which was exfoliate the heck out of your skin, but I stupidly used it on my face and my face was dry for most of the day even with heavy moisturizing. Although the peeling effect did do a good job at getting rid of extra layers of skin on the scar areas. It wasn't as harsh on the body though, which I guess was the whole point since it's a body soap, haha.
Also, just a comment about hydroquinone, why is it that America is one of the few countries who still market it for lightening? I haven't had results with it even when using it for months at a time, and stopped when I found it can result in cancer. I don't get why American brands can't get into the whole licorice, kojic acid, and papaya for skin evening and toning.
