Exclusive distributor in the Baltic states and Scandinavia: Sterile solution containing amino acids and ferments for revitalisation and toning of facial and body skin. ANTIRADICAL COMPLEX – a complex of amino acids and ferments with antioxidant properties, aimed against the free radicals and wrinkles. Amino acids are an excellent antioxidant with moisturising and regenerating action. They stimulate the growth and proliferation that results in faster production of collagen. Acetylcysteinum possesses regenerating action; it slows down ageing processes, gets rid of free radicals in the tissue, neutralises toxins, and stimulates protein synthesis Lipoic acid – the only antioxidant that acts both in the water phase (cytoplasmic) and lipid phase (in cell membranes). Owing to this property, lipoic acid protects the body from the free radicals both inside and outside the cell. It regulates metabolism of fats and hydrocarbons, close in nature to B group vitamin action. Lactoperoxidase is a strong antioxidant that blocks the free radicals. ANTIRADICAL COMPLEX invigorates the skin, advances regenerating processes, maintaining optimal condition of the skin. Ingredients: Volume: vial 5 ml Exclusive distributor in the Baltic states and Scandinavia: AMINOTONIC – sterile solution without conservatives, contains carnitine, caffeine, taurine, amino acids, and sodium chondroitin sulfate. L-Carnitine (levocarnitine) – natural substance that is part of cell content – plays an important role in the use of lipid substrates. L-Carnitine is involved in hydrocarbons and protein metabolism, increasing energetic potential of the cell. It also plays an essential role in tissue metabolism. Caffeine possesses biostimulating action. It significantly speeds up cell metabolism and advances triglyceride hydrolysis (lipolytic action). Moreover, it stimulates tissue drainage and expelling of statis (anti-edema function). Taurine is one of the most important inter-cell mediators and plays an important role in metabolism regulation. The product contains amino acids that stimulate endogenous collagen and elastin formation, speed up fibroblast proliferation and stimulate their growth, resulting in the increase of skin firmness and elasticity. Amino acids are used as a moisturising and regenerating substance with antioxidant properties. Sodium chondroitin sulfate stimulates hyaluronic acid synthesis, preserves water in tissue and strengthens connective tissue structures. AMINOTONIC, with its regenerative and restructuring action, advances optimal state of the skin as well as creates stimulating effect, restores elasticity, maintains tissue tonus. Indications: Ingredients: Volume: vial 5 ml Exclusive distributor in the Baltic states and Scandinavia: MEZO-LIFT — sterile solution without preservatives, containing DMAE, amino acids, vitamins, and microelements. DMAE possesses antioxidative and invigorating action, strengthening and stabilising effect on cell membrane, that results in toning the skin, blocking collagen degeneration, maintaining the skin youthful. Amino acids possess softening and healing properties. They are the basic element of proteins, collagen, skin keratin, nails and hair. Amino acids are widely used as a moisturising and rejuvenating means with antioxidant properties. Many vitamins create optimal environment for the free radicals, ensuring effective resistance to skin ageing processes, caused by age factors. Microelements stimulate the function of ferments, hormones and vitamins. MEZO-LIFT, owing to rich content of amino acids and vitamins, ensures visible antioxidative action, invigorating and strengthening effect. Outstanding lifting effect. Indications: Ingredients Volume: vial 5 ml Exclusive distributor in the Baltic states and Scandinavia: LIPOTENE is steril solution without preservatives, that contains hosphatidylcholine, sodium deoxycholate, L-Carnitine and Vitamin E, intended for professional use in cosmetology. LIPOTENE works on local fat deposits. Phosphatidylcholine is a lypolytic substance. Latest researches have proved that sodium deoxycholate reinforce the effect of phosphatidylcholine. Phosphatidylcholine – lipid-soluble molecules derived from soy, absolutely natural product without adverse effects, that decreases fat and cholesterol content. Phosphatidylcholine is able to completely expel fat masses through the kidneys. The use of phosphatidylcholine in fat cell accumulation areas causes lipocyte reduction and break down, as a result – local fat deposits gradually decrease. L-Carnitine (levocarnitine) – a natural substance and cell component, that plays an important role in the use of lipid substrates. The only substance able to transport long-chain fatty acids though inner mitochondrial membrane for their beta-oxidation. L-Carnitine also indirectly participates in hydrocarbon and protein metabolism, since fatty acid oxidation decreases peripheral use of glucose, advancing the involvement of acetyls (beta-oxidation products) in the Krebs Cycle, increasing the energetic potential of the cell. L-Carnitine plays a decisive role in effective detoxification processes and essential impact on the mitochondria, and also it has great importance in triglyceride metabolism (basic components of subcutaneous fat layer). Vitamin E is a powerful fat dissolving antioxidant found in many plants. It is an essential protective factor against cell ageing, protecting the body from the oxidation of membrane lipids and especially oxidation of fatty acid chains, that causes oxidation “stress” during the process of oxidation. Among antioxidants able to neutralise the free radicals, Vitamin E plays an essential leading role. It is one of the most active substances capable of neutralising the free radicals created by oxygen. When applied locally, Vitamin E provides moisturising, anti-inflammatory and soothing effect. Ingredients: Principle of action LIPOTENE’s targeted and local action decreases fat cell volume. This effect is especially important in the treatment of fat deposits that have developed under the influence of endocrine and metabolism factors or as a result of sedentary lifestyle, as well as in the treatment of deposits resistant to a diet and common methods. The results may be significantly improved by active use of draining, lipolytic and vasoprotective products in parallel. Thus, the content of fat cells is expelled and utilised in a natural way during several weeks after injection course. Indications • acts on local fat deposits Often diet and physical exercises do not provide significant result in fight against cellulitis. The situation worsens with age and is frequently connected to blood circulation problems as well. The fight against cellulitis is a complex of various measures; and in reaching the aim, one must observe the necessary measures and use all possibilities to be able to affect the existing changes in tissue. Contraindications LIPOTENE is not suitable for patients with distinct allergies and inflammatory processes. LIPOTENE is not suitable during pregnancy and lactation, for minor patients, for patients with suppressed immunity, soy allergy, kidney and liver failure.

A protective cream that serves as an extra-strong sun block, specifi cally designed for very delicate skins. Ideal when
used after peeling and cosmetic procedures; suitable for children and infants. The intense protective action is the result of the use of a combination of sun screens with a vast spectrum of UV absorption, complexed in closed nanosomes that increase their stability and prevent skin absorption, thus favouring local action and almost eliminating the already low toxicity of the complexed fi lters. The SPF 50+ and the excellent UVA/UVB ratio favour an almost total absorption of short UVA rays, which are the most harmful to the skin. Thanks to the ingredients, the cream assures the utmost effi cacy coupled with a softening and nourishing action. Does not leave white marks on the skin and can be used under normal make-up.
Bio Solar 50+ is a cream that has been developed to protect facial skin from UVA and UVB rays. It has a very pleasant texture, it is very easy to rub in and it does not make the skin white. Designed for skin that is fair, fragile or quick to burn, it is ideal for the fi rst few days in the sun and recommended for the delicate skin of children.
Bio Solar 50+ is also ideal for people with marks, scars or moles on their faces and bodies, or for protecting skin after beauty treatment.
Thanks to its properties, it can provide authentic beauty treatment for the face and help to keep the epidermis in great shape.
