Frequently Asked Questions

Throughout the years we’ve had lots of different questions about our SunSense products. These vary from the suitability of using with make up to the ethical credentials of our testing processes.

To read all our FAQ’s, head over to our dedicated FAQ’s page.

Here are 3 of our most frequently asked questions;


1.    What does dermatologically tested mean?

Ego dermatologically tests its products for skin sensitivity and irritancy on human subjects according to a strict patch testing protocol.


2.    Are SunSense products tested on animals?

No. Ego products are not tested on animals. Safety and efficacy testing is routinely carried out using in vitro methods or human volunteers. The use of human volunteers requires the study to be well designed and appropriately reviewed by established ethics committees.

Products are tested at an independent contract testing laboratory using human volunteers. Testing is in accordance to Australian standards. However, we cannot guarantee that our ingredient suppliers do not test on animals.


3.    What does the star rating system mean?

Only in the UK do we have a star rating system. It is a commercial device launched by Boots the Chemist.  The star rating does not communicate the amount of UV-A protection that a product delivers; it communicates only the ratio of UV-A which is absorbed as compared to the amount of UV-B that is absorbed in a very artificial laboratory test.


A rating of 3 stars mean that the average ratio of UV-A to UV-B is between 0.6 and 0.8, a rating of 4 stars means that the ratio of UV-A to UV-B that is being screened is between 0.8 and 0.9, a rating of 5 stars means that a ratio of 0.9 or above is being achieved.


All of the products in our SunSense range are broad spectrum sunscreens which protect against both UVA and UVB radiation. All of our SunSense sunscreens are tested to the Australian/New Zealand Standard 2604:1998. To meet this standard, a sunscreen must filter out greater than 90% of UVA radiation. All products in the SunSense range filter out between 95% to 99% of UVA radiation. They exceed the Australian and European Union requirements for UV-A protection and are among the most protective sunscreens that you can buy on the UK market.


Most SunSense sunscreens have 3 stars under the Boots star rating, meaning that they are achieving a ratio of at least 0.8.  Most SunSense sunscreens are also SPF 50+, which means that they are giving a very high level of sunscreen.  To be labeled SPF 50+, a sunscreen must be achieving at least SPF 60 in sunscreen testing.
