The deposition, delivery and penetration of actives are key to the success of skin care products and consequential to their efficacy. This paper explores ATR-FTIR imaging to compare the penetration of actives into skin via two application methods and their impact on skin hydration.

This article is the first of two that explores ways of capturing and quantifying the different forms of hair damage. Here, we begin with damage to the hair surface, or cuticle, while also exploring the implications of this occurrence. A second article will focus on damage to the internal cortex structure.

In cosmetics, soft focus refers to the blurring of light to immediately correct the appearance of wrinkles and skin imperfections. This parameter can be affected by the refractive index of the emollients used, as well as formula volatility and the dispersion of fillers. The use of eye tracking, described here, can help the formulator quickly select the best-performing formulas.
