This is a fantastic product. It has made my skin clearer and definitely more radiant. I have been using three times a week for a month now, recently boosted to every other day (word of warning that it may be a bit drying, at least if one jumps to daily use immediately).
The most unexpected for me result this product has had is that it actually faded a sunspot I have had on my cheek for years, and other lightening skin products never touched.
While I would say it is worth the money, I'm glad that The Skin Experts has offers regularly so I can keep buying because I'm not exactly a billionaire.
Keeping it in the fridge, wrapped in tin foil, has kept it fresh for at least a month now, so that's a suggestion I would make to everyone.
