Erythema and melanin indices are indicators quantifying skin erythema and pigmentation. With traditional colorimeters erythema measurement is often affected by melanin and vice versa.
This has been solved in the fully portable and pocket sized Delfin SkinColorCatch, which measures erythema and melanin indices insensitive to each other. The device also shows RGB, CIE L*a*b* and L*c*h* colour coordinates and calculates automatically the ITA degree, which classifies the skin tone.
The measurement is not affected by ambient lighting conditions and the optical orifice of the SkinColorCatch is designed to minimise possible blanching effects caused by the contact pressure against the skin.
