I have tried almost everything at this point and my skin doesn't want to lighten. The only things that work contain steroids or mercury. Don't be alarmed, this was years ago when I was uneducated... Even then, they did not make me light. Kojic acid has no effect on me and I have tried other natural products such as qei. I would like to try hq again, but even when I made a diy lotion I saw no results. When something does work it only lasts for a period of two weeks to a month e.g. Peau de lune. I take very good care of my skin and exfoliation/ sun protection is not the issue. I'd really appreciate it if anyone could chime in.
