Definitions

  • the present invention relates to the use of combinations of creatinine and / or creatinine derivatives with creatine and / or its derivatives in cosmetic or dermatological preparations for the treatment and prophylaxis of the symptoms of UV and / or ozone-induced skin damage as well as inflammatory and degenerative skin conditions.
  • Cosmetic skin care is understood primarily to strengthen or restore the skin's natural function as a barrier against environmental influences (e.g., dirt, chemicals, microorganisms) and against the loss of endogenous substances (e.g., water, natural fats, electrolytes).
  • environmental influences e.g., dirt, chemicals, microorganisms
  • endogenous substances e.g., water, natural fats, electrolytes
  • the aim of skin care is also to compensate for the daily loss of fat and water loss of the skin. This is especially important when the natural regeneration capacity is insufficient.
  • skin care products to protect against environmental influences, especially from the sun and wind, and delay the aging of the skin.
  • the chronological skin aging is caused eg by endogenous, genetically determined factors.
  • the epidermis and der is due to aging, for example, the following structural damage and dysfunction, which may also fall under the term "senile xerosis”: a) dryness, roughness and development of dryness wrinkles; b) itching; and c) reduced rehydration through sebaceous glands (eg after washing).
  • Exogenous factors such as UV light and chemical noxae can be cumulatively effective and e.g. accelerate or supplement endogenous aging processes.
  • exogenous factors occur, e.g. on the following structural damage and dysfunction in the skin that go beyond the extent and quality of the damage caused by chronological aging:
  • the present invention relates in particular to products for the care of naturally aged skin, as well as for the treatment of the consequential damages of photoageing, in particular of the phenomena listed under a) to g).
  • Products for the care of aged skin are known per se. They contain e.g. Retinoids (vitamin A acid and / or derivatives thereof) or vitamin A and / or its derivatives. Their effect on the structural damage, however, is limited in scope. In addition, there are significant difficulties in product development in stabilizing the active ingredients sufficiently against oxidative degradation. In addition, the use of vitamin A acid-containing products often causes severe erythematous skin irritation. Retinoids can therefore only be used in low concentrations.
  • the present invention relates to cosmetic preparations with effective protection against harmful oxidation processes in the skin, but also to protect cosmetic preparations themselves or to protect the ingredients of cosmetic preparations from harmful oxidation processes.
  • UVC range rays with a wavelength less than 290 nm
  • UVB range rays in the range between 290 nm and 320 nm, the so-called UVB range, cause erythema simple sunburn or even more or less severe burns.
  • UVA range it is important to have available filter substances, since its rays can cause reactions in photosensitive skin. It has been proven that UVA radiation leads to damage of the elastic and collagenous fibers of the connective tissue, which causes the skin to age prematurely, and that it is to be regarded as the cause of numerous phototoxic and photoallergic reactions. The damaging influence of UVB radiation can be amplified by UVA radiation.
  • UV radiation can also lead to photochemical reactions, in which case the photochemical reaction products intervene in the skin metabolism.
  • such photochemical reaction products are free-radical compounds, for example hydroxy radicals.
  • Undefined radical photoproducts which are formed in the skin itself, can also show uncontrolled sequelae due to their high reactivity.
  • singlet oxygen a non-radical excited state of the oxygen molecule can occur on UV irradiation, as well as short-lived epoxides and many others. singlet For example, it is distinguished from the normally present triplet oxygen (radical ground state) by increased reactivity. However, there are also excited, reactive (radical) triplet states of the oxygen molecule.
  • UV radiation counts as ionizing radiation. There is thus the risk that ionic species may also be formed on exposure to UV radiation, which in turn may intervene oxidatively in the biochemical processes.
  • antioxidants and / or radical scavengers can be incorporated in the cosmetic or dermatological formulations.
  • vitamin E a substance with known antioxidant effect in sunscreen formulations, yet here again, the effect achieved far below the hoped for.
  • the object of the invention was therefore also to provide cosmetic, dermatological and pharmaceutical active ingredients and preparations as well as sunscreen formulations which are used for the prophylaxis and treatment of photosensitive skin, in particular photodermatoses, preferably PLD.
  • Mainly antioxidants are used as protective substances against spoilage of preparations containing them. Nevertheless, it is known that undesirable oxidation processes can also occur in human and animal skin. Such processes play an essential role in skin aging.
  • antioxidants and radical scavengers are known.
  • the object of the present invention was therefore to find ways that avoid the disadvantages of the prior art.
  • the effect of repairing the damage associated with endogenous, chronological and exogenous skin aging and the prophylaxis should be permanent, sustainable and without the risk of side effects.
  • Creatinine is included in meat extract and meatballs.
  • Creatine is formed in aqueous solution. In the organism it is formed by transamidation of L-arginine to glycine to guanidinoacetic acid and their subsequent methylation by means of S-adenosylmethionine (by guanidinoacetate methyltransferase). Creatine is thought to be an appetizing ingredient in beef and meat extract. Creatine supplementation increases physical performance.
  • Cosmetic or dermatological preparations according to the invention preferably comprise an active ingredient combination of 0.001-50% by weight, particularly preferably 0.01-15% by weight, very particularly preferably 0.1-8% by weight, of creatine and / or creatine derivatives with 0.001-50% by weight, particularly preferably 0.01-15% by weight, very particularly preferably 0.1-8% by weight of creatinine and / or creatinine derivatives, based on the total composition of the preparations. It is advantageous to choose the weight ratio of creatinine to creatine from the range of 50: 1 to 1:50, preferably from 10: 1 to 1:10, particularly preferably from 2: 1 to 1: 2.
  • Preferred derivative is the creatine phosphate, which has the following structure: and which is widespread in fresh muscle where it plays an important role as an energy-storing phosphate (Phosphagen).
  • Phosphagen an energy-storing phosphate
  • creatine phosphate with adenosine 5'-diphosphate under the influence of the enzyme creatine kinase, releases adenosine 5'-triphosphate (ATP) and creatine; in the resting muscle the reverse reaction takes place.
  • ATP adenosine 5'-triphosphate
