You can go on
skin care, actives, skin care product, natural skin care, serious skin care, organic skin care, skin care information they don't have hq but they sell alpha arbutin, kojic acid, and glutathione(known to lighten the skin and aren't dangerous) they explain how to mix it in the same cream. It is a reputable seller!
I also would like to advice you to try to use some lactic or glycolic acid before starting the lightening process cause it cleans up the skin (lactic also lightens a little) If the skin is clean it will absorb better the lightening ingredients!
Then you need to buy some retin a to use along with the cream.
Good luck!
