Become a volunteer

Join our panel of volunteers and test tomorrow’s suncare products while receiving compensation.

WENEOS is the center of expertise for sun protection evaluation of cosmetic products worldwide. For over 25 years, we have been working with national and international regulatory bodies to develop ever more reliable methods.

Our clinical studies offer you the possibility of compensation, calculated according to specific requirements and proportional to your commitment. Each study is carefully supervised by our team of qualified professionals and carried out in compliance with current standards. This clinical research takes place during the final phase of product development, when the claimed effects must be demonstrated. We guarantee that our products contain only ingredients that comply with legal and regulatory requirements.

By becoming a member of our volunteer panel, you’ll play a key role in photoprotection innovation, while benefiting from a rewarding experience and fair remuneration. Your participation is crucial to ensuring the safety and efficacy of tomorrow’s suncare products. Together, let’s advance science and protect consumers’ skin.

You are now registered on our volunteer panel. We may contact you for research purposes.
 
Appointments are made via the volunteers area of our platform. Once you’ve been assigned to a study, you’ll receive an email confirming your appointment, along with instructions on how to proceed.
 
Note: We reserve the right to refuse your participation without compensation if you fail to comply with the timetable or instructions.

Criteria

Subjects, aged between 18 and 70, must have fairly fair skin on their backs and must not have been exposed to the sun for at least 1 month.

The test is performed on several areas of the back, between the shoulder blades and the waist, with the subject lying flat on his or her stomach.

These areas must be free of hair and skin imperfections (moles, freckles, brown spots, tattoos, scars or acne).

Economical

Compensation, calculated on the basis of attendance time, will be received 3 to 4 weeks after the end of the study.

Security

Handling is carried out by qualified personnel. Our experts are on hand to answer any questions you may have.

Preliminary tests have been carried out on these products to limit the risk of reactions. Rare possible effects include temporary irritation such as tingling, itching or redness.

 

Photoprotection

WENEOS undertakes only to carry out tests in accordance with its ethical policy.

We use a method (ISO 23698) that requires no exposure of volunteers to UV rays.

 

FAQ

K
L
How are suncare products assessed?

The efficacy of sunscreen products is assessed through several indicators, such as the Sun Protection Factor (SPF), the UVA Protection Factor (UVA-PF) and their resistance to various conditions (swimming, perspiration, rubbing, etc.).

At WENEOS, we have chosen to use the HDRS (Hybrid Diffuse Reflectance Spectroscopy) method. It is based on the reflection of light by the skin and/or the product. This innovative method is recognized worldwide through the ISO 23698 standard.

K
L
Are the products tested safe to use?

The products we evaluate have been previously validated in tolerance studies. This means that they can be applied to the skin without risk. A cosmetic product validated by tolerance studies is largely safe for the majority of consumers, but it is never 100% safe. Tolerance is individual, and there is always a small possibility of unforeseen reactions, particularly in individuals with sensitive or allergic skin.

K
L
How does an HDRS solar test work?

This type of test is carried out in two stages. The first stage requires the participation of volunteers. A test generally lasts around 2 hours, during which the volunteer lies on his or her stomach with his or her back bare. Zones are marked out, then a first series of measurements is taken on bare skin. Various sunscreen products are then applied to the zones, and left to dry. A second series of measurements is taken on skin with products applied. The back is then cleaned and the volunteer released.

K
L
Are these tests painful or risky?

Unlike traditional solar clinical studies, volunteers are not exposed to UV radiation. What's more, it's a simple measurement with a probe on the skin's surface. The whole process is painless and non-invasive.

K
L
How does a clinical trial work, and how can I become a volunteer?

A solar clinical study consists of several stages:

  • Voluntary database registration and completion of a registration questionnaire.
  • Validation visit to our premises, where you'll meet the person in charge of validating your registration in our database.
  • Recruitment survey, with completion of a short questionnaire, to confirm your participation in a particular test campaign.
  • Paid sun test on our premises for 2 to 3 hours.

K
L
How long does a test take?

A typical solar test takes around 2 hours. However, participation in special studies, such as water resistance, may require more time (up to 4 hours). The duration of the test will always be specified when you register for a solar study.

K
L
Do I need to bring anything with me on my visit?

At the first visit, to validate your file, you'll need to bring your identity card and carte vitale.

In the case of a visit for a sun test, a checklist will be sent to you when you register.
