Well Dime thankyou for the info on the product and though I'm Latina and not African American I do feel that having more melanin in our skin makes a difference. Examples of that are: certain skin treatments are not recommended for those with colored skin due to potential scarring, we have greater protection from the sun are less likely to develope skin cancers or burn, we are less apt to wrinkle, possibility of developing hyperpigmentation/melasma, people of color are more likely to have eczema as opposed to rosacea, and we are more apt to develope keloids.
I'm guessing that these are differences that you're speaking of? They are differences.
Anyway thanks for sharing the info and I visited his website and will be looking out for the product in Walgreens.
