Emerging Nanotechnology Involved in Skin Cancer: Pathogenesis, Biomarkers, Ethosomal Formulation and Future Perspective.

Skin cancer, which comprises both melanoma and non-melanoma forms, is frequently diagnosed as the predominant malignancy among today's population. Existing treatments are often prolonged and complex, have a low rate of success, and have side effects. This complexity leads to poor patient adherence and increases the risk of disease recurrence. Ethosomes, extensively studied for their applications in topical and transdermal therapies, are distinguished by their high ethanol content, which facilitates enhanced skin penetration and efficient drug delivery. Compared to traditional liposomes, ethosomes offer notable advantages due to their unique composition, demonstrating potential efficacy in treating various skin conditions, including basal cell carcinoma, squamous cell carcinoma, and melanoma. The present review provides a brief introduction to skin melanoma and its pathogenesis, signalling pathways, biomarkers, the need for ethogel-based drug delivery, applications of ethosomes against skin cancer, and clinical trials.
