...use great caution with the advice you bring.' Just what we need. Another critic scrutinizing appearance. And before coffee no less. Yet, this unbiased, digitized evaluation offers interesting potential; and if we don't like it, we can always turn it off.

Enhancing, Measuring Skin Penetration

Skin penetration is of great interest to personal care formulators for many reasons. Following are a few recent findings.

Predicting the Percutaneous Penetration of Cosmetic Ingredients

While previous algorithms for predicting the skin absorption of permeants was based on in vitro data, the present article proposes a quantitative structure-activity relationship (QSAR) model based on in vivo human data. Here, a set of human in vivo data is described that provides entry into predicting the penetration of cosmetic ingredients.

Rubbing Shoulders with Massage for Improved Penetration

Rubbing is a common application method for topical products, though evidence of its efficacy remains scarce. The present article reviews research in support of this application theory. It also identifies what investigation is still needed.

Testing for Penetration of the Skin Barrier

The skin barrier is described, after which tests and case studies illustrate how to show if actives and other ingredients have or have not penetrated the skin barrier.
