LUKE cosmetics

The production of the enzyme complex (Salizolis) involves highly qualified scientists, special equipment, controlled biotechnological processes and quality assurance. The selection of the microorganism Streptomyces gougerotii as the producer, its cultivation technology, and the production, isolation and purification of the enzyme complex began many years ago with the aim of creating a preparation that would actively promote the healing of skin lesions and help the skin regenerate after burns. And it worked – in preclinical studies, Salizolis was effective and led to better skin healing compared with the standard protocol for burn wounds.

Later came the idea of including the enzyme complex in cosmetic products. This is how the LUKE line was created, with a regenerating, skin-friendly effect.

Every batch of the enzyme complex is tested in a quality control laboratory to make sure it meets high quality requirements.

In cosmetics, it gently removes dead skin cells. Unlike acids, it cannot be overdosed, so there is no aggressive effect even if the cream is used several times a day. Of course, if strong exfoliation is needed, the enzyme complex will not provide it – it works without damaging the skin’s natural barrier, only gently “polishing” it.

Working non-aggressively, the enzyme complex also effectively promotes healing of skin cracks or lesions and prevents scarring. This is consistently confirmed by our best-selling product, the Ultra Hydrogel.

The products are suitable for sensitive skin, but people with very sensitive skin should assess the effect individually. There are universal products such as the Ultra Hydrogel, which is used even on cracked, chapped or stinging skin. It soothes, protects, maintains hydration and promotes skin healing.

Some LUKE products suit very dry and sensitive skin (e.g. the Regenerative Cream), while others suit sensitive skin with more active sebaceous glands (e.g. The Fount serum or the Avena moisturising cream).

We have also had some feedback that certain LUKE products improved the condition of skin affected by rosacea. If you are unsure which product to buy, we are always happy to recommend the most suitable option.

When the LUKE line was created, the primary goal of the products was to improve the skin’s recovery and regeneration functions and to strengthen its natural lipid barrier, which protects it from aggressive external factors. So you will clearly see a noticeable result if your skin was previously dry, chapped, affected by eczema or flaky. Relief and reduced discomfort are felt from the first day, and an overall improvement in skin condition is noticeable after a week of use.

LUKE products are not tested on animals. Some manufacturers still advertise “not tested on animals” as an advantage, even though testing finished cosmetic products on animals has been banned since 2004. In 2013, a complete ban was introduced (the full marketing ban), which means that no products or ingredients tested on animals may be placed on the EU market, wherever in the world the testing was carried out (source: European Commission).

Ideally, use the product within 3 months of opening. If you keep it in the fridge, this can be extended to 6 months.

Food supplements

Fortuna and Karna are made from soluble beta-glucans. They are immunomodulating products. The bottles contain combinations of beta-glucans of different molecular weights. This determines the product’s properties, use and duration of use. Read more about the effects in each product description.

The De-Pass food supplement contains insoluble beta-glucans, which work slightly differently, more like a prebiotic for our gut. Beneficial prebiotics, acting as mediators through lymphoid tissue (GALT – gut-associated lymphoid tissue) can indirectly affect the activity of other organs and bring about positive changes in the body related to the immune response and the nervous system.

Directions for use are given for each product. In some individual cases, following a doctor’s recommendations, the dosage schedule needs to be adjusted.

If you are taking medicines or have health problems, consult your doctor or pharmacist before starting the supplement. A food supplement is not a substitute for a varied and balanced diet.

Yes, but only after consulting a doctor.

Unlike the insoluble β-glucan supplements currently on the market that are used to stimulate the immune system, which the human body is unable to break down into the most bioavailable water-soluble fragments, the β-glucans developed by Biocentras are soluble and activate the target cells of the immune system as soon as they enter the body. By interacting with previously identified receptors on the cell surface, β-glucans begin to effectively stimulate the immune system and/or initiate processes that stop the proliferation of malignant cells.

High-molecular-weight beta-glucans activate phagocytes (macrophages), promote the synthesis of γ-interferon and thus stimulate the body’s immune system and destroy individual cancer cells.

Low-molecular-weight water-soluble β-glucans, by interacting with the CR3 receptors of neutrophils, initiate the destruction of all cancer cells.

According to the conclusions of the experimental study of the State Research Centre (No. ST-2017-09-04/01), Biocentras’ beta-glucan therapeutic composition called Imuno M inhibited the proliferation of cancer cells. Imuno M beta-glucan preparations suppressed the multiplication of SP2/0 tumour cells.

The beta-glucan preparation studied showed immunostimulatory properties, as it stimulated phagocytosis by macrophages. The most active stimulation of phagocytosis, up to 26%, was achieved with a 2 µg/ml concentration of the Imuno M-S preparation.

Yes. The buyer has the right to withdraw from a distance contract within 14 days without giving any reason. The product must be unused, undamaged, within its shelf life and in its original packaging.

Cosmetic products and food supplements whose packaging has been opened cannot be returned for hygiene reasons.

Environmental services

The first step is an eco-geological survey, which shows the concentration and extent of the contamination. Without these data, it is impossible to select a treatment method or prepare an offer. Next, a management plan for the contaminated site is prepared and agreed.

At the open site — from 3 to 18 months. The duration depends on the initial concentration, the composition of the pollutants, the soil type and the season.
