Abstract

As Brazilian men, in general, do not have the habit of use of skin care products and/or sunscreens frequently, and their skin health can be affected. The development of multifunctional formulations with sun protection, antipollution, antiacne and antioxidant properties could be a strategy to improve men's skin, since these protections are important to avoid the extrinsic ageing process. Thus, it is important to understand the penetration profile of cosmetic products since can present different pathways, such as intracellular, intercellular and/or follicular. Confocal Raman microscopy (CRM) is employed to study the skin physiology,drug permeation and skin disease monitoring. The in vivo resonance Raman spectroscopy can monitor the changes of cutaneous betacarotene and lycopene non invasively. The method is quick, painless and can be repeated easily. This way, free essential oils and/or nanoemulsions of these active substances can be good alternatives to prevent the free radical formation and alternative acne treatment. In this context, the objectives of this study are to utilize these noninvasive techniques to analyze the penetration of active substances (essential oils, nanoemulsion and UV filters) in the skin and the capacity to reduce free radical formation in cosmetic formulation.
