Wella Professionals Elements Renewing Mask Paraben Free

DESCRIPTION

What It Does: Softens and conditions skin by integrating into sc lipid bilayers, delivers essential fatty acids (oleic, linoleic, linolenic) for barrier lipid synthesis, and provides rich, non-stripping moisturisation.

Why It's Used: Natural carrier oils provide the closest compositional match to endogenous sc lipids, delivering emolliency through genuine barrier integration rather than simple surface occlusion.

How It Works: Fatty acid triglycerides partition into sc lipid bilayers — oleic acid (c18:1) provides fluid, emollient integration; linoleic acid (c18:2) acts as essential ceramide precursor; saturated fatty acids provide more occlusive barrier reinforcement.
