      Interesting. The way the monograph works for acne products is that the researchers will have to show much more data to get it included as a viable active which formulators could use.

        Thank you so much sir for this wealth of information. But my question is if cosmetic products cannot penetrate the stratum corneum, how then does all these skin lightening creams produce a visible result. The main claim of skin lighteners is that it reduces melanin and melanin is produced by melanocytes in the stratum basal. I would really appreciate your take on this

        1. Perry Romanowski

          Hello Anita – Well, for the most part skin lighteners don’t work. The only one proven to work is Hydroquinone and that ingredient is able to penetrate deep enough in the skin to affect melanin production.
