To evaluate the effect of a topical application of a cream formulation containing extract of Acacia Nilotica
bark extract on human cheek skin texture.
A cream containing 3 % concentrated extract of Acacia nilotica
bark was developed by entrapping the extract in the internal aqueous phase of the cream having strong antioxidant activity. A similar cream but without the extract was also prepared. Each of the formulations was applied to the cheeks of 11 human volunteers for a period of three months. Both cream formulations were assessed, using Visioscan VC 98, for various parameters including texture parameters (energy, contrast and variance) as well as for skin roughness (Ser), skin scaliness (SEsc), skin smoothness (SEsm) and skin wrinkles (Sew).
Unlike the cream base, the extract cream exhibited steady, significant improvement in skin parameters over the 3-month period of application. Images showed visible improvement of the overall skin appearance and reduction of fine lines by the extract cream. Furthermore, skin texture (variance and contrast) and SELS (SEr, SEsc, SEsm and SEw) parameters showed significant decline (p < 0.05) and the texture parameter of energy showed significant increase (p < 0.05).
Our findings indicate that the cream containing 3 % Acacia nilotica
bark extract possesses anti-aging effect and improves skin surface appearance.
