A skincare containing retinol adenosine and hyaluronic acid optimises the benefits from a type A botulinum toxin injection

Abstract Introduction: A monocentre double-blind two parallel group clinical study was conducted to assess whether a new skincare regimen containing retinol, adenosine and hyaluronic acid, applied after the injection of botulinum toxin A to the glabellar area, provided a beneficial effect. Material and methods. Standardised photographs acquired using LifeViz cameras and zoomed pictures of the glabella and of the crows feet areas were analysed with automatic well-defined procedures. Perceived efficacy and tolerance were also analysed by comparison between the two groups. Results: A beneficial effect versus placebo-treated group was proven in the group having topically applied the new skincare regimen for 2 months following botulinum toxin A injection with no touch up after 1 month. 3D image analysis showed more rapid results on D10 and enhanced efficacy on M2. Moreover, a beneficial effect independent of injection was measured in the crows feet area, and analysis of the self-evaluation questionnaire showed enhanced efficacy perceived by the volunteers. Conclusion: A specially developed skincare regimen applied immediately after botulinum toxin A injection completes the beneficial effect of the injection on the glabellar area and offers clinical benefits in fine lines, wrinkles and smoothness on the whole face.
