Test profiles for claims
Product Claim: Anti-age spots, anti-pigmentation, protective, soothing Test profile: Measuring skin colour - melanin (pigmentation) and erythema (redness)
Product claim: Firming, tonifying Test profile: • Measuring the hydration of the stratum corneum (capacitance method). • Measuring skin elasticity of the upper skin layer using the suction method • Measuring skin surface relief utilising SELS parameters (Surface Evaluation of Living Skin)
Product claim: Moisturising, nourishing Test profile: • Measuring the hydration of the stratum corneum (capacitance method). • Measuring skin surface relief utilising SELS parameters • Measuring skin dryness (desquamation - size and quantity of corneocytes) • The size and quantity of corneocytes. • Measuring sebum content (skin lipids) of skin surface and secretion per surface area.
