Pycnogenol® + Centellicum® supplementation improves skin elasticity and microperfusion. Implication for surgical patients: a conceptual registry study.

Abstract

Background: The aim of this registry study was to evaluate the effects of Pycnogenol^® and Centellicum^® (PYCE) on skin perfusion and skin elasticity in healthy women over a period of 4 weeks.

Methods: The supplemented women used 150 mg of Pycnogenol^® and 450 mg of Centellicum^® daily. The supplemented group used the combination PYCE daily for 4 weeks and followed the standard management (SM) in addition. A control group used only the SM. SM for all subjects included a healthy diet (low levels of NaCl, low sugar, low calories), vitamin supplementation (C, E, B), daily mild outdoors exercise, regular washing with neutral soap; the same non-clinical, non-specific hydrating cream (Nivea) was used once daily.

Results: Sixty-three women completed the registry study. Thirty women using the PYCE combination and 33 women in the control group. The groups were comparable at baseline. No clinical condition was observed during the registry; no drug was used. There were no side effects or tolerability problems with the supplements. After 4 weeks, ultrasound elastosonography showed that skin elasticity significantly improved with the PYCE combination (P<0.05) without significant changes in the control group. In parallel, transcutaneous skin PO2 increased significantly with PYCE compared to controls and transcutaneous skin PCO2 decreased significantly compared to controls (P<0.05). This showed that skin oxygenation and nutrition improved with PYCE. Skin hydration also significantly improved with PYCE (P<0.05) in comparison with controls. Skin flow, indicating skin blood perfusion (thermoregulatory flow), assessed by laser Doppler flowmetry significantly improved over 4 weeks compared to controls (P<0.05). More specifically, the most superficial part of the flow, in the most superficial layer of the skin, corresponding to the nutritional blood flow, significantly improved with the combination PYCE compared to controls (P<0.05). Skin and tissue elasticity are crucial in surgery for healing, scarring, and wound closure. Reduced elasticity can lead to irregular or delayed healing. This preliminary concept study suggests that PYCE supplementation enhances skin elasticity, perfusion, and nutrition, with visible effects seen in just 4 weeks.

Conclusions: This preliminary, concept study indicates that skin elasticity, skin perfusion, and skin nutrition improved with the supplementation of PYCE and the effects of PYCE were visible after only 4 weeks. A longer observation period should be considered in future studies. In conclusion, this pilot concept study shows a significant activity of the combination Pycnogenol^® and Centellicum^® on skin elasticity over a short period of supplementation.
