    Hi Beauty Brains,

    Thanks for another fantastic episode – as always, found your insights into the beauty industry fascinating. The two of you discussed on this episode the usage of the Corneometer and Novameter in skincare product testing for moisturization, which my friend and I found really interesting. Can you share a little more about how the large skincare companies typically test their products for efficacy?

    Thanks and look forward to another informative episode!

      It really depends on the specific claims they are making. For skin products the corneometer and novameter are popular options in which subjects are put in a room with controlled temperature and humidity. Product is applied and control sites on the skin are chosen. Then we measure change in skin readings over a few hours. There is also the Kligman regression test for moisturization which requires over 2 weeks of testing.

    I enjoyed the discussion of dermatologist blended products. I am happy to have found a doctor who does not sell her own products. Years ago I took my daughter to a different doctor to treat her very dry skin. The doctor suggested I buy a jar of her moisturizing cream. I decided to give it a try. When we got home and started to use the cream, I peeled off her label and discoveredI had bought a jar of Eucerin for twice the drugstore price. Needless to say I never went back to this doctor.
