In the run-up to the test, we defined practical requirements and the following test criteria:
- Safety and security
In order to evaluate these criteria, we have defined several tests for the laser hair removal devices. First, the scope of delivery and functions are checked. In the test runs, the upper and lower legs as well as the armpits are treated. The settings are always adapted to the tester (light skin, dark hair).
The test runs check whether the procedure is painless on the one hand and on the other hand evaluate handling, user-friendliness and ergonomics. In addition, the time required is stopped and the volume measured.
After the first sessions, it is checked whether skin irritations occur as a result of the treatments. The applications are carried out as recommended by the manufacturer and it is checked when the first results are visible. Finally, it is tested after which period of time a new treatment is necessary. The test period is several months.
In order to rule out mistakes and to ensure the strain of everyday use, each test takes place in several rounds.
The test criteria receive percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.
Our product selection is based on observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.
