Skin barrier: this refers to dead callus cells that are compacted into a lipophilic mass by lipids (fats).

Lipids are 95 percent ceramides, cholesterol, waxes, fatty alcohols (triglycerides) and hydrocarbon compounds (squalenes). The foot skin has a rather low lipid content. The foot soles have no sebaceous glands to produce lipids. Here, epidermal lipids are almost exclusively formed from metabolic products during skin regeneration. This is also why the foot skin generally tends to be dry, and can develop excess callus, cracks and sensitivity under pressure and environmental influences.

Care emulsions with higher lipid content are advisable for these typical skin problems. Such emulsion types largely use plant based oils as their lipid base, as well as lanolin from sheep‘s wool or specific hydrocarbons (Vaseline, mineral paraffins).

The high-grade plant oils used by GEHWOL have the highest possible content of premium nutrients that are important for skin care, such as fatty acids and vitamins.

In liquid consistency, plant oils have a high share of polyunsaturated fatty acids such as linoleic acid and linolenic acid. They are an important part of the ceramides and are therefore among the particularly barrier intensive lipid components of the skin. Olive oil and wheat germ oil have especially high proportions of linoleic acid. Saturated fatty acids such as palmitic acid and stearic acid are also processed in the skin.

Oils with a high content of palmitic acid include avocado oil and sea buckthorn oil, both of which have excellent skin smoothing properties. Certain solid plant fats are known for their high share of fatty acids, such as shea butter from the nuts of the shea tree. Their solid, spreadable form means that these fats are also suitable for imparting a firmer consistency to some emulsions (such as butters).
