These creams (Ambi, Skin Success, Nadinola) contain less than 4% hydroquinone and according to scientific research, OTC hydroquinone 2% preparations are typically less effective than the prescription 4% preparations.
Your spots may stand a chance if you add penetration enhancers such as glycolic acid and tretinoin as a supplement to the pigment lightening agent (the aforementioned creams). That said, and speaking from experience, using these creams (alone) have not been effective in treating the dark spots on my body.
I’ve heard people say that Ambi has worked for them…
Do you have any experience using these? General thoughts?
