Yes, Lifesystems Sun Creams comply with the latest European standards. We also test on real people in real situations to make sure the product feels right as well. However, to be entirely sure, we recommend that you do a patch test before travelling.

Our Sport Sun Protection Cream (which is the new version of the Active) is ideal for travel and low-altitude outdoor use. This version is extremely waterproof, so it is ideal for high activity use over long periods, in or out of the water. As well as this, the Sport Sun Cream has an anti-jellyfish formula built in, so this is really a great product for sport and travel alike.

Mountain Sun Cream is ideal for use at high altitude. Sunburn can occur very quickly at high altitude where UVA protection is so important. Our Mountain Sun Creams contain 5-star UV filters that protect the skin from harmful UVA rays. They are also sweatproof so will last longer during high levels of activity.

The Sport Anti-Jellyfish Sun Cream contains a natural extract which binds to the jellyfish sting sensor on contact and blocks it; as a result, the signal that would usually trigger a sting response does not arise. Other active ingredients within the cream combine to mimic substances found within the Jellyfish's own body, and so on contact, the Jellyfish thinks it is touching itself and does not fire a sting.

Lifesystems Sun Creams have been tested for sensitive skin and hypoallergenic. The Sun Cream does not contain ingredients at a concentration that are known to generate comedones formation (clogged skin pores).

The Lifesystems Sport Sun Cream is certainly "Reef Safe". Over the past 20 years scientific studies have concluded that the influential damage to corals apart from global warming is from tourism. It has been demonstrated that major coral damage is caused by people swimming/scuba diving and breaking the coral or covering the coral with sand from swimming. In every place where these parameters have been eliminated coral reefs have started to recover.

To conclude, the damage to coral from wearing Sun Cream in coral areas has never been proven. Advantages of the Lifesystems Sport Sun Cream formula over a regular Sun Cream is the water and silicon based formula. The silicone shield holds the Sun Cream filters for much longer to the skin and therefore stops it diluting it in the water for up to 80 minutes.

Our Sun Cream formulations do contain a perfume which is hypoallergenic and suitable for sensitive skin.
