How we test IPL machines

We use lab testing and a user trial to rate the hair removal devices.

For the price, you want an IPL to work

Do you find hair removal a hassle? Have you tried epilators and shaving and just been disappointed with how short term the effects are? Intense pulsed light (IPL) treatment can provide more permanent hair removal. Here's how we test home IPL machines at CHOICE:

For our IPL reviews, we put each model through performance testing in our labs, and conduct a user trial to find out how effective and easy they are to use.

Our expert testers

Since our last review in 2011, our testers have been itching to see how IPL devices have improved. Our testers are passionate about determining a product's technical performance. We're happy to say the effectiveness and safety of these products has improved since our last test. 

How we choose what we test

With so many models to choose from, what makes us choose one IPL to test over another? As with most of our product testing, our aim is to test the most popular models on the market and what you're most likely to see in the retailers.

We survey manufacturers to find out about their range of models, we check market sales information and we check for any member requests to test specific models. From this information we put together a final list that goes to our buyers. They then head out to the retailers and purchase each product, just as a normal consumer would. We do this so we can be sure the products are the same as any consumer would find them and not 'tweaked' in any way.

How we test

User trial

Twenty women aged 18 to 52 with medium-strong dark hair and light skin (this combination of pigmentation gives the most effective hair removal results) tested the products on their legs. The application was done in random order and each panellist tested six appliances on one leg. The area to be treated was standardised and was highlighted with white mascara before every application. One leg was treated with the IPL while the other leg was left untreated as comparison. Four applications were made every 15 days. Before starting the test, the women shaved both legs.

The evaluation of hair removal efficacy was done by visual inspection from experts with the help of a microscopy (hair number/density, hair diameter and hair length) and a questionnaire to panellists.
