Dry skin treatment using a multifunctional topical moisturizer
The development of dry skin is a complex process, with a wide variety of factors each playing different roles in its evolution. Given this, it is important when designing a formulation to tackle dry skin that these varied aspects of skin behaviour are addressed. Reserchers now presented in a recently published study the results of a 3 week moisturization study carried out on dry legs. A wide range of traditional and more recently developed biophysical measurement methods have been combined with visual assessment of skin condition to enable multiple aspects of skin function to be determined. The observed changes in the skin are discussed in terms of the ingredients used in the moisturising formulation.
Creamide EOS and NP increased
Statistically significant improvements were observed in a range of skin parameters as a result of product usage. Skin hydration assessed using “Corneometer”, “Epsilon” and visual dry skin grading all increased after 3 weeks of use. Skin barrier function measured using transepidermal water loss also improved. Levels of cholesterol, free fatty acids, and Ceramide NH increased, as well as the average length of the stratum corneum (SC) lipid lamella bilayers, and the ratio of lipid to protein increased (measured using Lipbarvis® and in vivo Confocal Raman Spectroscopy). Increases in the levels of Ceramide EOS and NP were also observed, along with an improvement in corneocyte maturity, although these were not statistically significant.
Using a range of traditional and novel skin assessment techniques, a wide range of factors associated with the evolution of dry skin have been assessed upon treatment with a new topical moisturizer. Product usage resulted in a significant improvement in skin hydration and barrier function, levels and morphology of SC barrier lipids, and overall epidermal differentiation. This resulted in significant improvement in the factors associated with the development of dry skin.
The study hast been published in International Journal of Cosmetic Science.
