Protective and anti-inflammatory effects of a dermocosmetic formulation containing a combination of vitamins

The exposome accelerates the skin aging process, highlighting the need to use cosmetics capable of repairing the damage and maintaining the skin's physiological conditions. Thus, the present study aims to evaluate the potential anti-inflammatory and protective action of a dermocosmetic formulation combination of vitamins. For this, a gel-cream formulation added or not with 3% of ascorbyl tetraisopalmitate and 1% of D-panthenol was developed. The stability and sensory properties of these formulations were evaluated. In addition, a short-term clinical efficacy study of the formulations was carried out for 7 days. After this period, measurements were taken in terms of transepidermal water loss and blood microcirculation by Laser Doppler at the initial time and after the application of methyl nicotinate. The results showed that the formulations remained stable during the study period and showed pseudoplastic non-Newtonian behavior. In addition, the association of vitamins was effective in the protection of the skin against the effects of methyl nicotinate by reducing blood microcirculation, which suggests that the active substances in combination can have an anti-inflammatory and protective action on the skin barrier function.
