Hyaluronic Acid-Based Dual-Functional Hydrogel Microneedle System for Melanoma Ablation & Skin Regeneration

 

1. Introduction

Melanoma, a highly aggressive form of skin cancer, poses significant challenges for effective treatment due to its invasive nature and recurrence risk. Traditional therapeutic methods often cause damage to surrounding healthy tissue and require prolonged recovery time. Recent advancements in biomaterials have led to the development of hyaluronic acid-based hydrogel microneedle systems that can deliver dual-stage therapy. This innovation offers a unique approach by combining localized melanoma ablation with subsequent skin regeneration, thus minimizing side effects and enhancing post-treatment recovery outcomes.

2. Design and Composition of Hydrogel Microneedles

The hydrogel microneedle system is composed of biocompatible hyaluronic acid, chosen for its excellent skin penetration and hydrophilic nature. The needles are fabricated using micro-molding techniques to ensure uniform size, strength, and mechanical stability. This structural integrity allows the microneedles to painlessly penetrate the skin barrier and deliver therapeutic agents directly to the target site with high efficiency.

3. Mechanism of Sequential Melanoma Ablation

The first phase of the system focuses on melanoma ablation through localized drug release or photothermal therapy. The microneedles deliver active agents directly into the tumor tissue, maximizing therapeutic concentration at the site and minimizing systemic toxicity. This targeted approach enhances the efficiency of cancer cell destruction while sparing healthy surrounding tissues.

4. Skin Regeneration and Healing Process

Following ablation, the second functional stage of the hydrogel microneedles promotes tissue regeneration. Hyaluronic acid itself supports wound healing by retaining moisture and stimulating fibroblast activity. In addition, growth factors or regenerative molecules may be incorporated to accelerate collagen deposition and skin remodeling, ensuring rapid recovery and improved cosmetic outcomes.

5. Clinical Implications and Advantages

This dual-functional microneedle approach offers several advantages over conventional melanoma treatments. It reduces patient discomfort, minimizes scarring, and lowers the risk of infection. Furthermore, its sequential delivery mechanism ensures precise control over treatment stages, leading to better therapeutic outcomes and higher patient satisfaction.

6. Future Research and Potential Applications

Future studies may focus on optimizing drug-loading capacity, enhancing microneedle dissolution rates, and integrating smart-release mechanisms responsive to tumor microenvironments. Beyond melanoma treatment, this platform can be adapted for other skin disorders, including chronic wounds, psoriasis, and even cosmetic dermatology applications, highlighting its versatility in biomedical research.

Global Recognition of Skin Diseases as Public Health Priority

Image
The 78th World Health Assembly made history by unanimously adopting the resolution titled ‘Skin diseases as a global public health priority’. This resolution marks shift in recognising skin health as a critical aspect of global public health. The decision reflects years of advocacy and the need for better funding and attention towards skin diseases, particularly in low- and middle-income countries (LMICs). Historical Context The resolution emerged from years of advocacy led by dermatologists and organisations like the International League of Dermatologic Societies (ILDS). Skin diseases affect approximately 1.9 billion people worldwide, yet they have been historically neglected. This resolution aims to change the narrative, denoting skin health as integral to human dignity and social equity. Voices from Low-Resource Settings Experts from regions with limited dermatologic care stress the urgency of this initiative. There is a critical need for increased funding and integration of skin he...

Mercury in Online Skin-Lightening Cosmetics: A Health Risk Assessment Across Asia

   1: Introduction Skin-lightening products remain widely popular across Asia, but recent research highlights alarming mercury contamination in many online-purchased creams. This introduction explores the growing demand for lighter skin, the cultural factors driving product usage, and the potential health risks tied to mercury exposure, including kidney damage, neurological disorders, and skin complications. The study focuses on products sourced from multiple Asian countries, evaluating their safety and the implications for public health. By understanding the severity of the issue, we can better advocate for safer beauty practices and stronger regulatory actions.  2: Mercury Contamination in Skin-Lightening Products Mercury is often used in skin-lightening creams for its melanin-inhibiting properties, but its presence poses a major toxicological concern. This section highlights how mercury enters cosmetic formulations, its illegal use despite regulations, and its concentr...
