| Yep, best bet would be to make your own HQ solution if you're looking for higher concentrations.
You can find pure HQ powder (a bit costly, but 99% pure and legitimate) on several skin-based sites. Diluting it with regular lotion should work effectively.
Average price I've seen is about 1oz/28 grams for about $15; cheaper than Arbutin, despite my choice to stick with it. |
