Instrumental & Biophysical
What is Instrumental & Biophysical?
Why do you need this service?
Select instrumental and biophysical endpoints from the exact claim, target population and conditions of use. Appropriate measurements can be combined when each answers a relevant question. The study schedule and market-specific substantiation expectations should be agreed before testing.

Instrumental and biophysical testing
This service group connects cosmetic claims with measurable endpoints in human studies. Instruments record physical properties before and after product use under controlled conditions. Clinical grading and participant feedback can complement these measurements but should remain distinct from instrumental results.
Skin ageing and body firmness
Anti-ageing testing measures wrinkle appearance and mechanical properties using imaging, profilometry or cutometry. Body firmness testing applies site-specific biomechanical assessments to areas such as the arms, thighs or abdomen.
Hair, scalp and nails
Hair care studies assess strength, breakage, shine and related performance endpoints. Nail care studies examine hardness, flexibility, surface condition or growth, while scalp care testing can track dandruff, oiliness and scalp condition through imaging, scoring and sebum measurements.
Hydration, lips and barrier function
Hydration testing uses corneometry to assess outer-layer skin hydration. Lip care testing combines suitable hydration and barrier measurements with lip-specific observations. Skin barrier testing examines transepidermal water loss and recovery-related endpoints rather than treating hydration alone as proof of repair.
Makeup and oil control
Makeup performance studies document wear, colour retention and transfer resistance. Sebum regulation testing measures surface oil and shine under defined collection and measurement conditions.
Skin appearance
Pigmentation testing tracks colour and dark-spot appearance using colorimetry and imaging. Radiance studies evaluate brightness and luminosity, while skin texture testing quantifies surface roughness and pore appearance.
Soothing, sun protection and under-eye care
Soothing studies assess redness and discomfort using suitable clinical and instrumental endpoints. Sun protection testing determines SPF and related protection measures using market-appropriate methods. Under-eye studies assess puffiness, dark circles, fine lines or hydration with methods suited to that area.
Claims substantiation connects study design and interpretation to the wording of the intended claim. Duration, participants and analysis should be selected for that question rather than assumed from the service category.
Choosing efficacy endpoints for a claim
Begin with the exact statement proposed for the tested formula, including its duration, comparator and intended users. Select measurements that directly address that statement, then define application, observation and analysis conditions. Target-market expectations should be checked before commissioning the study.
A moisturizer study might combine hydration and barrier measurements when both are relevant, with the results interpreted separately. Sun-protection statements need the applicable SPF or UVA evidence rather than general skin-response markers. Combining endpoints is useful only where it answers the brief; the service category does not dictate a universal test package.
Cosmetic efficacy testing measures biological endpoints in cell, tissue or ex-vivo models to investigate mechanisms behind proposed benefits. Explore another Cosmetic Efficacy Testing page on cosmetic-labs.com.
