Instrumental testing for cosmetics

To confirm the efficacy and safety of cosmetics, the subjective feelings of users are not enough. Instrumental testing for cosmetics allow precise, quantitative assessment of a product's effect on the skin, hair or other biological structures. Thanks to modern measurement methods, it is possible to accurately determine the effects of cosmetics, providing important support for both manufacturers and consumers.

What parameters do the apparatus tests assess?

Instrument studies use advanced technologies to objectively analyse various aspects of skin and hair function. Assessments include:

• Moisturising the skin - using corneometry, which determines the hydration level of the epidermis after application of the cosmetic,
• Skin elasticity and firmness - measurements using cutometers that analyse the biomechanical properties of the skin,
• Reduction of wrinkles - evaluation of anti-ageing effects using skin surface analysis equipment,
• Sebumetry - sebum analysis, crucial in cosmetics for oily and acne-prone skin,
• Measurement of discolouration and skin tone - spectrophotometric evaluation of pigmentation changes after cosmetic application.

Each instrumental testing provides reliable and measurable data to help scientifically evaluate the effectiveness of cosmetics.

Why is apparatus testing important for cosmetics manufacturers?

High competition in the market requires manufacturers to prove the claimed effects of their products. Instrumental testing for cosmetics allow reliable results to be obtained confirming a cosmetic's effectiveness in reducing wrinkles, improving hydration or smoothing the skin. These tests allow brands to highlight the scientific basis of their formulas, which builds customer confidence.

Results instrument tests can also be used in marketing strategies, advertising campaigns and on cosmetic packaging. Scientifically proven performance is an important competitive advantage.

A comprehensive analysis of cosmetic efficacy requires a combination of different testing methods. In addition to instrument tests, the key ones are preceding:

• Physico-chemical tests - assessing the stability and physicochemical properties of the cosmetic, such as pH, density, viscosity or water activity,
• Microbiological tests - microbiological purity and preservative efficacy tests to ensure the safe use of cosmetics,
• Application research - tests conducted on groups of volunteers to assess users' subjective perception of the product's comfort and effectiveness.

Combining the results from different studies provides a complete picture of a cosmetic's properties and performance.

When is it worthwhile to carry out instrumental tests on cosmetics?

Instrument studies should be carried out at several key moments:

• During the development of the new formula, to assess the real effects of the active ingredients,
• Before a cosmetic is marketed, to confirm the efficacy claimed by the manufacturer,
• In a comparative study with other products on the market,
• When testing reformulated cosmetics to assess improvements over the earlier version.
