There have been several approaches to modulate skin parameters
with respect to influencing skin appearance under cosmetic
aspects. With the surface evaluation of living skin
method one can evaluate the skin structure and obtain information
on roughness, scaling and wrinkling. Intervention
with flaxseed or borage oil led to changes in roughness and
scaling, which might be in part explained by the observed
modulation of skin hydration and firmness. However, a parameter
such as wrinkling, which results mainly from changes
in the molecular structure of extracellular components, was
not affected by any of the treatments
