The clinical test: The best assessment of product performance

Since the day our company was founded, we have always respected the highest standards of effectiveness, quality and safety. Clinical studies and instrumental measurements are used to evaluate the performance of a Cellcosmet skincare product to ensure the greatest objectivity possible.

Meaningful results are obtained by performing an average of six instrumental tests. For each test, an independent professional uses a device, technology or method.

Hydration

Skin hydration is measured by a corneometer, which emits a weak electrical current through the skin. The better moisturised the skin is, the better it conducts electricity and the less this current is resisted, providing an accurate measurement of hydration level.

Barrier function

Skin barrier function capacity is evaluated with a TEWLmeter (Trans Epidermal Water Loss). It measures the amount of water that naturally evaporates from the skin. High measurements indicate a deterioration of the skin barrier.

Wrinkle depth

Skin barrier function capacity is evaluated with a TEWLmeter (Trans Epidermal Water Loss). It measures the amount of water that naturally evaporates from the skin. High measurements indicate a deterioration of the skin barrier.

Radiance + redness

The skin colorimeter uses light to measure skin absorption/reflection. A circular light evenly illuminates the skin, then the probe measures and indicates the reflected light, providing information about skin colour.

Elasticity + firmness

The cutometer measures skin’s viscoelastic properties with a suction and elongation method, interpreted by an optical measurement system. 2 parameters are evaluated: overall elasticity (the skin’s ability to return to its original state) and distensibility (how well the skin resists deformation during suction).

Tolerance + tone

The dermatologist evaluates the skin’s reactions after the product has been used for 7 and 28 days and records the sensations experienced by each person. They also observe the formation of blackheads and assess the product’s comedogenic potential.

Skin microbiota analysis

A bacterial skin sample is taken and the gene common to all bacterial cells is isolated by PCR. This gene is sequenced to measure microbiome diversity, an indication of good skin health, with the Alpha Diversity (for a sample) and Shannon Diversity Index (for proportional abundance of types).
