Analysis of Agave tequilana Extract and Chitosan Dissolving Microneedles

What is it about?

This study demonstrates that it is possible to incorporate blue agave root extract into biodegradable chitosan microneedles while preserving some of its antioxidant and dermocosmetic properties. However, the amount of extract must be carefully controlled, as high concentrations can deteriorate the microneedle structure and reduce some of their biological activities. In particular, the formulation with 0.25% extract showed the best balance between structural stability, cell safety, and preservation of bioactivity.

Why is it important?

Many natural compounds offer skin benefits, such as antioxidant, anti-inflammatory, and protective effects. However, one of the biggest challenges is ensuring these compounds penetrate the skin effectively to be truly effective. Microneedling is an innovative technology that can help address this challenge. It creates tiny, temporary channels in the skin, allowing active ingredients to be released more efficiently without the need for traditional injections. In this study, biodegradable microneedles made of chitosan (a natural material derived from chitin) containing extract from the roots of Agave tequilana were developed. The objective was to evaluate whether this extract could be successfully incorporated into the microneedles, maintain its biological properties, and preserve the stability and shape of the system.
