A Review of Topical Oils on the Skin | Benefits, Research & Applications

 1. Introduction

Topical oils have been integral to skincare for centuries, offering hydration, nourishment, and protection. With increasing consumer demand for natural and effective products, research has focused on understanding how oils interact with the skin barrier, influence hydration levels, and impact dermatological health. This review aims to summarize scientific insights into the role of oils in topical applications and their therapeutic relevance.

2. Composition of Topical Oils

The chemical makeup of topical oils varies widely depending on their source, ranging from plant-based oils like jojoba, coconut, and argan, to mineral and synthetic oils. Research highlights how fatty acid profiles, antioxidants, and bioactive compounds influence oil absorption and efficacy. Understanding composition is essential to evaluate suitability for different skin types and clinical uses.

3. Effects on Skin Barrier Function

A key area of research investigates how oils strengthen or disrupt the skin’s natural barrier. Certain oils rich in linoleic acid restore barrier function and improve hydration, while others may occlude or irritate depending on their composition. Studies emphasize the importance of selecting oils based on skin physiology to enhance protective functions without adverse outcomes.

4. Therapeutic and Clinical Applications

Beyond cosmetic benefits, topical oils show promise in therapeutic dermatology. Research demonstrates their role in managing conditions like eczema, psoriasis, acne, and wound healing. Essential oils with anti-inflammatory and antimicrobial properties also provide alternative approaches for skin disorders, bridging natural remedies with clinical evidence.

5. Safety, Toxicity, and Allergenic Concerns

While topical oils offer benefits, safety remains a major research focus. Certain essential oils can cause allergic reactions, photosensitivity, or cytotoxicity at high concentrations. Clinical evaluations stress the importance of dosage, formulation, and dermatological testing to ensure oils are safe for prolonged use in both cosmetic and medical contexts.

6. Future Directions in Oil-Based Skincare Research

Emerging research explores novel formulations such as nanoemulsions, encapsulated oils, and synergistic blends to enhance bioavailability and stability. With growing interest in personalized skincare, future studies will likely investigate genetic and microbiome-driven responses to topical oils, paving the way for customized and science-driven skin treatments.

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...
