Clinical trials for skincare and cosmetic brands

What are skincare and cosmetic clinical trials?

Cosmetic and skincare clinical trials are a great way for brands to validate their products’ performance while creating science-backed claims that drive business growth. Clinical studies showcase that your products actually work and can help with website and ad conversions, wholesale listings, and forging trust toward your customer base.

Why should you conduct research?

Differentiate your brand with a clinical trial

Most skincare, cosmetic and personal care products promise a lot. From fewer wrinkles to improved hyperpigmentation and younger-looking skin. Positive reviews are great, however, most consumers also want to see that the claims you make are research-backed. Brands that go the extra mile to create clinically proven claims for their products stand out with consumers by giving insight into a product’s real-world performance. Citruslabs supports the clinical testing of your skincare, cosmetic and personal care products and helps you to substantiate your product claims and embed scientific validation into your brand.

Why Citruslabs for your skincare clinical trials?

Decentralized clinical studies with expert skin grading

Customized clinical studies (*as long as they're virtual)

Consumer perception studies

Many cosmetic, beauty, skincare, and personal care brands are increasingly conducting decentralized clinical trials. This study design has the advantage that it is more cost-efficient (especially compared to in-person studies). A decentralized clinical study with Citruslabs always includes expert skin grading in addition to validated and study-specific questionnaires. 

At Citruslabs, we understand that no two skincare brands and products are the same. This is why we offer fully customizable study designs to match your unique needs and goals (as long as they're virtual and don't require in-person visits). Our studies provide you with reliable subjective and objective data, as well as at-home before and after photos. 

Consumer perception studies are the easiest and most cost-efficient way to create claims backed by data. These studies assess the perceived benefits of skincare and other cosmetic products. Most skincare and cosmetic brands opt for consumer perception studies with at-home before and after photos.

Before and After photos 

At Citruslabs, our specialized service includes the provision of before-and-after photos to vividly demonstrate the efficacy of your wellness product. Embraced by numerous brands, this visual documentation effectively captures and showcases the remarkable changes in participants' hair, skin, and body, enhancing the overall impact of your product. Learn more about the option of before and after pictures.

Case study

Common Heir partnered with Citruslabs to stand out from the crowd

The Challenge

Common Heir is a skincare brand launched in April 2021 with a vitamin c serum. As a luxury brand, Common Heir’s goal is to make clinical research part of its brand identity. Given that new skincare lines are popping up left and right, it was important for them to show from the start that their products and claims are actually backed by research, especially as they are not only a luxury brand, but also a clean beauty brand. 

The Solution

In just 5 months, Citruslabs designed, conducted, and completed a clinical trial for Common Heir, with claims (and before and after photos) ready for their launch day.


From day one, Common Heir created trust in their new customer base, by proving research-backed information on the efficacy and safety of its products through a clinical trial. As the first study with Citruslabs was a victory, Common Heir successfully completed another clinical study with Citruslabs with a very diverse set of study participants on their retinol serum that included expert skin grading as well as before and afters.

FAQ about cosmetic trials

What is the difference between consumer perception studies and clinical trials?

A consumer perception study is significantly less scientific than a clinical study. A perception study has the goal of "just" creating claims. It's still a robust study, but just for the sake of making claims that are based on data. 

Perception studies typically include 30-40 participants that are generally healthy. They don't screen for specific inclusion and exclusion criteria (except for age and some high-level concerns that participants have - e.g. fine lines, wrinkles, age spots, thinning hair, etc.). Perception studies typically don't have a comprehensive baseline questionnaire (many don't have a baseline questionnaire), because the goal is to make claims. However, perception studies typically have a "before & after photos". The study check-ins (typically just 1 or 2) have 5-10 questions that are targeting claims. For example: "do you agree that the product reduces the appearance of fine lines and wrinkles?", measured on a Likert scale from 1 (strongly disagree) to 5 (strongly agree).

When opting for a clinical study, typically the goal is to create more robust, truly scientific/research-backed claims. Companies opt for a clinical study because they want statistical analysis, they want to publish their report somewhere, or they want to be taken more seriously by the medical community. Typically supplement brands and more sophisticated skincare brands opt for clinical studies, because then they can include biomarkers (or skin markers). In a clinical trial, brands can also include more sophisticated questionnaires, or even (University-) validated questionnaires, they can clearly define the inclusion and exclusion criteria of study participants, and also include more details, for example, "participants shouldn't take this and that medication/supplement", "participants should have this and that health condition", "participants should have this and that lifestyle". Additionally, clients can include study-specific questionnaires (similar to perception studies), to help make their claims, but they can also add validated questionnaires to the mix. Questionnaires for clinical studies are typically around 40 questions. Also, clients can then include biomarkers/skin markers/digital markers, and of course, before and afters, which can also be clinically graded. Typically, clinical studies get IRB approved (perception studies don't). And clinical studies can also come in the forms of randomized-controlled studies, while perception studies are usually single arm. 

What does dermatologist-approved mean?

Dermatologist approval simply means that a dermatologist has signed off on the safety and efficacy of a product. It actually doesn’t mean that a clinical study is involved, it really just means that a dermatologist gave their blessing for a product.
