Lactic acid

Lactic acid

Lactic acid is one of the AHAs or alpha-hydroxy acids. In cosmetics, lactic acid is used to regulate the product’s pH and as a humectant and exfoliating agent. It hydrates and brightens the skin, strengthens the skin’s protective barrier and boosts the skin’s ceramide production. Lactic acid also occurs naturally in the skin’s Natural Moisturizing Factor (NMF), which is created during the keratinization process as a result of the breakdown of filaggrin. In concentrations of more than 5%, lactic acid acts as an exfoliating agent.

Djusie’s Peace Out Reviving Essence contains a very low concentration of lactic acid, the purpose of which is to adjust the pH of the product. The concentration is so small that it has no skin care effects.

Lecithin

Lecithin – Switzerland

Lecithin is used in cosmetics as an emulsifying agent, i.e. it enables water and oil to mix. It also softens the skin. The lecithin used in Djusie’s products is an ingredient in the mastic resin extract in the moisturizer.

Lentinus Edodes extract
Shiitake mushroom extract – France

 

Revered in Japan as the “Elixir of Life”, the shiitake mushroom is celebrated for its regenerative and protective power. Djusie uses a titrated shiitake extract, standardized for its lentinan and β-glucan content – ensuring consistent bioactivity and clinically proven efficacy in activating the skin’s immune system.

As we age, or under UV and environmental stress, the skin’s immune system weakens.
Lentinan, a natural polysaccharide composed of βD-1,3 and βD-1,6 glucans, reactivates Langerhans cells, keratinocytes, and macrophages, triggering the skin’s natural immune defense. It stimulates interleukin-1 (IL-1) production, enhancing cell communication and protecting against inflammation and premature ageing.

The shiitake extract used in Djusie’s products is titrated with a precisely standardized composition: it contains 2% lentinan and 0.5–4.5% β-glucans, along with 38% essential amino acids and trace elements such as copper, iron, magnesium, manganese, and zinc. It is also a natural source of vitamins B1 and B2, as well as provitamin D2, which support the skin’s metabolism and vitality.

Lingonberry extract

Vaccinium Vitis-Idaea Fruit Extract, lingonberry extract – Estonia, wild grown

Lingonberries are hand-picked from the forests in Nordic countries. They grow in some of the cleanest forests in the world where winters are harsh and sun shines almost 24 hours in a day during the summer. This makes the plants to produce high amount of polyphenolic compounds. Lingonberries are packed of antioxidants, vitamins and minerals. Lingonberry extract helps to neutralize the effects of free radicals and signs of premature ageing.
