Core Lifesystems Product Types

Insect Repellents

Lifesystems repellents use micro-encapsulated DEET (20–50%), IR3535®, or plant-based citriodiol—ingredients proven in CDC and WHO trials to protect against mosquitoes, ticks, and biting midges. Their formulas offer up to 12 hours of protection and are sweat- and water-resistant.

Popular choices include the EX4 50% DEET Spray for high-risk malaria zones and the gentle DEET-Free Repellent for children aged 6 months and above.

Sun Protection

All Lifesystems sunscreens are fragrance-free, hypoallergenic, and suitable for sensitive or eczema-prone skin. They use photostable UVA/UVB filters and micronised zinc oxide for broad-spectrum SPF 50+ protection—ideal for face and body.

Bestsellers include the SP50+ Family Face Sun Cream and Lip Balm SPF30—both reef-safe and non-greasy.

Travel First Aid Kits

Compact yet comprehensive, Lifesystems first aid kits are recommended by expedition medics and align with WHO travel guidelines. They include antiseptics, blister plasters, rehydration salts, antihistamines, and wound dressings—all organised in waterproof, lightweight cases.

Choose the Large Medical Kit for family trips or the Mini Pocket Kit for festivals and weekend breaks.

How to Use Lifesystems Safely

Apply repellent to all exposed skin—avoiding eyes, lips, and broken skin
Reapply sunscreen every 2 hours, or after swimming or heavy sweating
For children under 2, avoid DEET 50%; opt for DEET-free or DEET 20% where appropriate
Store all products below 25°C and check expiry dates before travel

Trusted Quality You Can Rely On

Unlike generic travel products, Lifesystems is registered with the MHRA as a medicinal biocide where required, and every batch is tested for stability at high temperatures (up to 45°C)—ensuring it works when you need it most. The brand is regularly recommended by the National Travel Health Network and Centre (NaTHNaC) for UK travellers visiting tropical regions.
