iossi natural skin care

Our Ingredients

IOSSI cosmetics consist of natural oils, organic butters, vitamins, plant extracts, essential oils and many other carefully selected ingredients that have a beneficial effect on the skin, body and hair. Descriptions of their properties can be found below:

The citrus complex (orange and lemon), maple syrup and sugar cane are the sources of several AHA acids (glycolic, lactic, malic and lemon) responsible for cleansing the skin and regulating its pH, restoring its natural and physiological qualities. The most important function, however, is to prepare the skin for the next steps of care by supporting the absorption of active ingredients.

Chia Seed Extract - an extract incorporating an anti-pollutant influence, i.e. it creates a protective barrier on the skin against the damaging effects of external factors such as air pollution and smog. Additionally, it contains a moisturizing effect, reducing the evaporation of water from the upper layers of the epidermis.

Blueberry extract - an antioxidant component - removes excess free radicals, which enhances the appearance of the skin. It contains alpha-hydroxy acids, vitamin PP, beta-carotene and vitamin C, which have a favourable effect on skin exposed to sunlight. This extract has a strong astringent effect - the ingredients contained in blueberries cause the damaged layers of skin cells and mucous membranes to shrink.

Liquorice extract - contains saponins, flavonoids and organic acids, which facilitate the retention of water in the tissues, and hence moisturizing and soothing the skin. It increases the capacity of active ingredients to penetrate deep into the skin.


Hyaluronic acid - a compound that occurs naturally in the human body. It has hygroscopic properties (the ability to bind to water molecules), thus effectively moisturizing the skin and preventing the evaporation of water from its surface.

Lactic acid - it effectively unclogs the pores of the skin, thus enabling its cleansing. It regulates the pH of the skin and restores its natural, physiological qualities.


Niacinamide - vitamin B3 is an ingredient that is suitable for all skin types and is beneficial for most skin problems. It increases the hydration and elasticity of the skin and reduces transepidermal water loss (TEWL). It supports the skin’s defence against discoloration by inhibiting the migration of pigment from melanocytes and thus preventing the creation of visible discoloration.

The retinol [Nikkol Retinol H 10] which we use, is a derivative of vitamin A, which actively moisturizes by strongly stimulating the synthesis of hyaluronic acid in fibroblasts. It stimulates the skin's natural protective system. As a result, it prevents the formation of wrinkles and it also has a slightly exfoliating factor - thus it has a strong moisturizing, anti-aging and revitalizing effect. Retinol H10 is a very stable form of vitamin A that is resistant to light, heat and oxidation.

Vitamin E - inhibits skin aging, protects against dryness and weakens the elasticity of the epidermis. Tocopherol exerts a protective effect on the lipids of cell membranes, increasing their ability to bind to water through the skin. In addition, it reduces skin discoloration, occurring or resulting from excessive exposure to UV radiation.

Vitamin C - stimulates better blood supply to the skin, by supporting the collagen synthesis process, which affects the firmness and elasticity of the skin, strengthens the walls of the blood vessels, brightens the skin and reduces wrinkles.
