Clinical tests with the E-One

To evaluate the E-One’s performance against professional IPL devices, E-Swin founded a scientific committee. The committee gathers doctors, lecturers, dermatology experts and hair specialists to ensure that their findings are broad and expert. The mission was to conduct a full range of tests in many different contexts to determine how the E-One performs, and to evaluate its performance against the other IPL devices on the market.

In 2008, the committee embarked on a clinical study under medical surveillance, with 63 volunteers participating in a survey. The volunteers were both male and female, ages 18 to 55, with a wide range of skin types (photoypes II, III and IV).

The first phase of this investigation took place in a renowned Parisian hospital and also in a private clinic based in Aix en Provence. The objective of the first phase was to confirm absolute tolerance levels and to rate the superiority of the E-One (using its IPL technology) versus wax depilation. Wax depilation was chosen for comparison as it is the most commonly used form of hair removal. In this trial, the underarm area was selected to undergo testing. A hair removal session was performed on each individual, selected randomly, with a balance of wax depilation and E-One treatment.

Dermatology examinations were performed both 15 minutes and 24 hours after the first hair removal session. Two dermatologists, who were external from the committee, examined and evaluated pictures of each subjects’ underarm area, without revealing the treatment method.

Further hair removal sessions and dermatological examinations were conducted; images were taken to monitor progress every 7 weeks at the laboratory by the technicians.

Results: tolerance

The results show that there is no long-lasting irritating effects when using the 2 techniques.

• 15 mn after hair removal, we notice very light redness amongst only 21% of the participants with the E-One (versus 46% with waxing) and in any case, no important redness (versus 11% with waxing).
• After 24h, with the E-One, only 3% still have light redness (7% for waxing).
• 15 mn after hair removal, we notice a very light inflammation for only 7% (14% for waxing) and after 24h, there is no inflammation with both techniques.

Results: efficiency

Best results on the underarm every 7 weeks (49 days):

Average of the results according to the two investigators.

After only 2 treatments, the results are very positive since 85% of users prefer using the E-One over waxing.

100% of the users prefer using the E-One than waxing starting from the seventh treatment…
