Studies, literature and statements

Kursbuch Kosmetik, page 154

Moisture protecting, smoothes the skin.

Springer Lexikon Kosmetik, page 174

Three-value alcohol in nature as well as a component of animal and plant fats and fat oils. Water-absorbing. In higher concentrations (from 30%), dries and irritates the skin. Moisture suspending material for improvement of the brushability of O/W emulsions and soaps, denaturing material, solution material.

Körperpflegekunde und Kosmetik, page 143

Glycerine is a preservative in more than 20% dilution. The concentration employed should not, however, exceed 30%, because it is strongly hygroscopic and pulls water from the skin, which can lead to very strong irritation. On the other hand, this effect can be used in lower concentrations as a positive, as a moisture retainer or a softener in emulsions and hydrogels.

Wikipedia

Due to its water-binding properties, glycerol is included in cosmetics as a moisturizer.

Kosmetik- Inhaltsstoffe von A-Z, page 81

Is used in cosmetics as a humectant, because glycerol is highly hygroscopic. Depending on the concentration, it may have negative effects in skin care products if it dehydrates the skin, due to insufficient humidity in the air. Irritating to mucous membranes in higher concentrations. Humectant in toothpastes.

Almost all skin and aging problems are due to nutritional deficiencies of the skin. That is why nutrient suppliers such as vitamins, trace elements, amino acids, secondary plant substances and high-quality essential fatty acids in cosmetic products are of great importance for healthy skin
