FAQ - Frequently asked questions

Currently, the ISO 16128 standard is a reliable and international way to determine the naturalness of cosmetic products. It defines ingredients of natural origin and introduces so-called product naturalness index, which is the percentage of natural ingredients in the cosmetic. DuoLife products feature a very high naturalness index, and their compositions are based on natural, certified ingredients. The naturalness index of DuoLife Beauty Care Aloes Liquid Soap amounts to 94.6%.

Joint existence of those three ingredients, i.e. pre, pro and postbiotics ensures quick multiplication of microorganisms in the natural microbiom of the body, favourable to our skin. A prebiotic is a substance which may be used by beneficial bacteria and it is a breeding ground for them. Prebiotics are living microorganisms which are helpful for the skin microbiom and in our washing balm, they occur in the form of Lactobacillus cells. Finally, the postbiotics are lysates and metabolites produced by living bacteria during the fermentation process. In DuoLife washing balm, it is a mixture of organic acids, including the lactid acid.

Aurafirm P, containing prebiotic, probiotic and postbiotic is a colloidal oat flour, fermented with Lactobacillus. It is a serum which deeply penetrates and stabilises the skin bareer. It contains a complex of amino acids, fatty acids and phospholipids, fills wrinkles, restores correct balance of skin microbiom and affects an increase in the positive bacterial flora. It favours multiplication of beneficial Staphylococcus epidermidis strain and hinders development of pathogens on the skin.

The product also uses sea water from the French Atlantic coast with a high content of minerals. This ingredient ensures effective hydration, strengthening and detoxification of the skin.

The skin of our hands is every day exposed to contact with detergents or disinfectants containing ethanol. In addition, external factors such as wind, sun or frost make the hands dry, rough and chapped. Liquid hand soap DuoLife Beauty Care Aloes Liquid Soap is a unique product with the properties of a balm. It is characterized by a cleansing and refreshing effect, but also intensively caring. The product  contains as much as 15% of natural sunflower oil rich in essential fatty acids and vitamin E, thanks to which it nourishes the skin and helps increase its elasticity, eliminating the feeling of roughness and chapping.

The high content of sunflower oil (15%) in the product prevents it from foaming like traditional cosmetic products.

The product is not intended for children or infants.

Due to the content of sodium lauroyl sarcinosate, the product should not be used by pregnant women. 

Yes, all DuoLife cosmetics are tested dermatologically. In this case also it was proved that the product meets the requirements of the skin compliance test.

No. Simarly to all the other cosmetics available on the EU market, the balm has not been tested on animals. Since 2004 testing on animals is forbidden in the EU, and since 2009 it is also forbidden to use in cosmetics any ingredients tested on animals. It is a legal misuse to use declarations ‘not tested on animals’ on packaging of cosmetic products.
