Sun Protection and Insect Defence: A Guide to Using Sunscreen with Insect Repellent

The warmer months bring with them the challenge of protecting oneself against the sun's UV rays and stopping those insect bites. Integrating the use of sunscreen with Natural PMD-based insect repellent is a methodical approach to protection. This guide aims to explain the advantages of PMD repellents over synthetic alternatives like DEET, especially when used alongside sunscreen, and provide a clear protocol for its application.

PMD vs. DEET: The Benefits of Natural Repellents in Conjunction with Sunscreen

PMD (p-menthane-3,8-diol) is derived from the refined oil of the Java Citronella plant. It’s natural benefits, especially when combined with sunscreens, surpass synthetic repellents:

  • Compatibility with Sunscreen Formulations: Natural repellents like PMD interact less with the chemical compositions of sunscreens. In contrast, DEET has been observed to sometimes reduce the efficacy of sunscreens by up to one-third. This can be the difference between protecting yourself from the sun and getting burnt. 
  • Decreased Skin Irritation: PMD is much gentler on the skin than aggressive synthetic chemicals, reducing the risk of adverse reactions that might be exacerbated when combined with sun products.
  • Natural Origin: The use of PMD offers a reduced exposure to synthetic chemicals, potentially decreasing long-term health risks associated with prolonged chemical use.
  • Environmentally Considerate: Being biodegradable, PMD is more eco-friendly than many synthetic alternatives. This is a huge benefit for the environment. 


Application Protocol: Sunscreen and PMD-Based Repellent

For effective protection, follow this order:

  • Apply Sunscreen First: Start with a broad-spectrum sunscreen of at least SPF 30, allowing 10-15 minutes for absorption.
  • Timely Reapplication: Activities like swimming or excessive sweating will cause you to need to re-apply both products. Always begin with sunscreen.


Recommendations for Optimal Results

  • Opt for sunscreens providing broad-spectrum protection.
  • Ensure the PMD repellent chosen contains at least a 20% concentration for optimal defence, or even Tropical Strength 25% 
  • Separate products for sun protection and insect repellence are advised to ensure the integrity and effectiveness of both.



Protection from UV rays and insect bites is essential during outdoor activities. By combining sunscreen with PMD-based repellent, one can ensure robust dual protection. Additionally, the use of PMD, with its natural profile and compatibility benefits over synthetic chemicals like DEET, offers a safer and more effective combination when layered with sunscreen. Follow the above guidelines for a secure and enjoyable outdoor experience.
