Does it work?
Ahh! Thanks ONdine maybe 3x a day will work for my knees and elbows..Nikesh, did you just ask & answer your own question? Unusual...YES HQ4% will safely lighten most complexions. The darker & thicker the skin, the longer it'll take & you may need to apply it 3x/day. You don't absolutely need glycolic acid, but exfoliants DO speed the process if your skin tolerates them well. Nikesh, I posted an incredibly useful article re HQ that you ought to take a look at. It'll answer many questions that arise. Every time I read it, I spot something I'd missed.
Hey.. how long after applying HQ would you suggest putting on your favorite moisturizer??Hey JAYICE. Hydroquinone will only darken from over use. Once you have reached your goal limit to only nightly use. Also sun screen is a must. If u feel it drying, please moisturise.
