This is pretty cool/exciting. Might not last long on face because we scrub/exfoliate/moisturize there.
I would ask Dr. B when you can try this. Even though it is a single, LIST 2 ingredient, you are putting it on skin so it goes into your blood stream right away so may be too strong till later/after treatment.
OK, are you curious? What is the single ingredient and how do you apply it? ;)
