product efficacy at Dr. Whitney Bowe Beauty

you deserve to have proof that your skincare really works.

We take science-backed beauty seriously—our founder and CEO, Dr. Whitney Bowe, is an award-winning, practicing board-certified dermatologist and a published scientist.

100% of our products are clinically-tested at third-party labs to ensure they deliver results.

clinically-tested, potent ingredients

We prioritize ingredients that deliver real results, valuing efficacy over novelty.

clinically-tested, final formulas

Ingredients matter, but the final formulation matters more. We test the final formula you have in your DWB Beauty bottle in third-party labs, versus relying on data from our ingredient suppliers.

clinically measured results

We use cutting-edge clinical skin instruments and technology to measure how our products change the skin. When we test our final formulations, we often supplement our consumer perception studies, or “subjective analyses,” with what are called “objective analyses.” In other words, in addition to asking our panelists about their experience using our products, we will go one step further.


objective studies

Here are clinical skin instruments, plus cutting-edge technology we use to measure how some of your DWB Beauty products impact the skin.
TEWL
Uses an instrument called a Tewameter® to measure “transepidermal water loss,” or how much water is evaporating from skin. If the skin barrier is damaged, water loss will increase and skin becomes dehydrated.

When we claim a product supports a healthy skin barrier, this test has proven that the product decreases the skin’s water loss, indicating an improvement in skin barrier function.

CORNEOMETRY
Uses an instrument called a Corneometer® to determine the level of hydration in the skin.

When we claim a product increases skin’s hydration, this test has proven it improves skin moisture by measuring electrical capacitance to assess skin’s hydration.

NEXT GENERATION SEQUENCING TECHNOLOGY
Helps to understand how the skin microbiome is impacted by products.

When we claim a product supports a healthy microbiome, it has been tested in vivo (on living humans) to assess its effect on the skin microbiome. We look for richness, diversity, and balance.

CLINICAL IMAGE ANALYSIS
Precisely and reliably quantifies meaningful results on the skin.

When we claim a product improves skin redness, tone, texture, or depth of fine lines or wrinkles, this technology is one assessment tool.

100% of our formulas are created by a dermatologist who took a Hippocratic Oath, a promise to do no harm.

We are uncompromising when it comes to the efficacy and safety of our products. While we focus on what’s in our products, we do disclose what’s deliberately left out—not because each of these ingredients is “unsafe,” but because we believe you have a right to avoid ingredients you find sensitizing or less sustainable. We are also proudly cruelty-free.

every ingredient and final formula is screened for its potential to create irritation and ensure its safety.

RIPT TEST
We use the Human Repeated-Insult Patch Test (HRIPT) to evaluate the sensitization potential of a product.

IRRITATION TEST
Even after our products pass the HRIPT tests, we continue to assess for irritation and sensitization. In our clinical studies, 50% of our subjects have sensitive skin, making our irritation tests even more rigorous.

TRIPLE TESTED FOR PURITY
Our Inner Skincare is triple tested for potency and purity. We test, and re-test each individual ingredient, and then conduct additional testing on the final formulation.

High-Performance Packaging

Our packaging helps to preserve each formula’s potency, giving you results until the very last drop. Packaging solutions include airless technology to protect from oxidation, and opaque components to shield from UV degradation.
