Ingredients (INCI declaration of the ingredients):

Aqua, Glycerin, Alcohol, Dihydroxyacetone, Lactic Acid, Sodium Hyaluronate, Sodium Hydroxide, Magnesium Stearate, Sodium Metabisulfite

Further explanations of the ingredients:

Aqua:
Water. It makes up approximately 65% ​​of the weight of the human body and is therefore essential for bodily functions, including those of the skin. In many cosmetic products (aqueous solutions, cleansers, emulsions), water is the ingredient with the largest proportion of the formulation and forms the basis of the aqueous phase in emulsions. Water is a good solvent for polar (hydrophilic) substances such as alcohols, water-soluble vitamins, or salts. For use in cosmetic products, the water used is generally pre-treated to remove microorganisms that could lead to product spoilage or dissolved salts that might impair the stability of emulsions or gels (sterilization and desalination).

Glycerin:
Body-identical, a component of the natural moisturizing factor and lipids/triglycerides. Improves skin hydration, influences the consistency and texture of cosmetic products, and has antimicrobial properties.

Alcohol:
Ethyl alcohol: Biocompatible. Has a refreshing and antibacterial effect. Also serves as a solvent for other ingredients. Contrary to other claims, there is no risk of a drying effect on the skin at normal concentrations!

Dihydroxyacetone:
It is an intermediate product in carbohydrate metabolism in the human body. It reacts with the keratin in the outermost layer of skin to form a brown pigment, thereby producing a natural-looking tan.

Lactic Acid:
Lactic acid. Occurs as a metabolic product in the body and on the skin; in higher concentrations and at a low pH value of 2 to 3, it has an exfoliating effect on the stratum corneum; in buffered form (physiological pH value of the skin approx. 5.5), it supports the moisture content and preserves the skin's acid mantle.

Sodium Hyaluronate:
Sodium salt of hyaluronic acid. A natural moisturizer with skin-smoothing properties, an important natural component of the lower layers of the skin (dermis). Formerly extracted from rooster combs, it is now produced biotechnologically in improved quality.

Sodium Hydroxide:
Sodium hydroxide. Used to adjust the pH of cosmetic products. Sodium and hydroxide ions are identical to those found in the body.

Magnesium Stearate:
Magnesium salt of stearic acid. Filler in powders, improves lubrication and adhesion.

Sodium Metabisulfite:
Sodium disulfite serves as an antioxidant and stabilizer, e.g. in self-tanning products.
