Only if you want to take part in sun studies. A qualified professional must check that you meet the dermatological criteria. The visit is done once.

For all other studies it is not needed: you can receive invitations by email as soon as you complete your registration.

When a study matches your profile you will receive an email with all the details. If you are interested, apply and choose the time that suits you. If you are assigned a slot, you will receive a confirmation email.

If you see “no slots available”, all places for that study have been filled.

Let us know as early as possible by WhatsApp or email. If there are free slots we will try to reschedule; otherwise your participation in that study will be cancelled.

If you do not finish a study, because you cannot attend the agreed visits or have not followed the protocol correctly, you will not receive compensation for that study.

Not when both involve the same body area or when taking part in both could interfere with either, whether at our centre or elsewhere. This is stated in the exclusion criteria of each study.

By bank transfer.

Once issued, a transfer can take up to 48 working hours to arrive.

They are sent to the address in your profile, so make sure it is correct. When they ship you will get an email and WhatsApp notice with the tracking number and courier.

If the parcel has not arrived within 48 h, contact the courier directly. Each study has a deadline stated in the instructions, so make sure you receive the samples in time.

They require certain medical and dermatological characteristics. The main criteria include:

• Fair skin tone
• Even skin on the back (no marks, scars, extensive tattoos…)
• Aged 18 to 70

These and other criteria are checked in the sign-up form and during the medical visit.

Short studies: a recent method that assesses a product’s protection on the back in just 1 hour. No redness, pigmentation or discomfort.

Long studies: two consecutive days on a small area of the back to determine SPF. After the first day mild redness may appear, similar to sun exposure, which fades progressively. Compensation is higher, usually between €60 and €90 depending on the study.

No. They follow a standardised, controlled procedure. UV exposure is localised to a small area of the back, with doses calculated for your skin type.

In long studies temporary redness may appear in the test area, which is needed to determine the level of protection. You will be fully informed beforehand and your skin type will be checked.

No. Each study is completely independent. Every invitation states the type of study and you decide freely whether to join.
