The present invention relates to a kind ofly can promote the medical cosmetology of cell new life and delay skin aging to win peptide more, wherein this medical cosmetology wins peptide more and comprises victory peptide and pharmaceutically acceptable carrier, this beauty treatment sequence how the victory peptide is comprised of 13~20 aminoacid, this beauty treatment peptides that win have suitable effect for increase skin elasticity, minimizing dermal melanin, reinforcement skin from the master lock outlet capacity more.
Background technology
1. the reason of skin aging
The formation of skin aging is very complicated process, has involved countless physiological phenomenons.The aging origin cause of formation is as many as stars, general mainly can be divided into extrinsic factor (Exposure to Sunlight, pollution, free radical injury, smoking), and intrinsic factor (cell natural death, natural aging, hormone minimizing, immunity reduce), under inside and outside multiple aging action impact, skin will inevitably be dry, lax, produce wrinkle and follow the string, and loses gradually young gloss.
The reason of skin aging has a lot: the reduction of skin oxygen concentration, free radical injury, collagen protein reduce, cell turnover slows down, paracytic appearance, skin fat minimizings, intercellular substance shortage, Growth of Cells are stopped, hormone decline etc., all be the partly cause of skin aging, also have numerous other reasons to participate in the process of skin aging.
By and large, skin aging can be owing to following four factors:
1. the degeneration of collagen protein and elastic fiber (mainly being caused by aging, free radical and uv damage);
2. the minimizing of skin epidermis and the fat deposit impact of gravity (aging and);
3. the countenance (causing the wrinkles such as the stricture of vagina of frowning, crows-feet and decree stricture of vagina) that repeats;
4. laxity of ligament and cause the lax phenomenon of the sagging and skin of muscle.
Collagen protein and elastic fiber are the skeletons of skin texture, after long-term ultraviolet injury, and their gradually disintegrate minimizings, becoming does not have elasticity.Young skin has more moisture content and fat than aging skin, and therefore aging skin seems drier transparent, and fat people seems that wrinkle is less.In addition, skin area can continue to enlarge along with the age, and the fatty tissue of bottom reduces gradually, skin area increases, but do not have enough bone (bone also can along with the age degenerates) and fat to support, add gradually atrophy of facial muscle, so the sagging phenomenon of cutis laxa produces.
The composition of skin also can reduce gradually along with the age, and water conservation composition and structure composition such as the nerve amines of intercellular substance, hyaluronic acid, Polysaccharides, glycerol etc. exhaust that gradually collagen protein and the elastic fiber of skin are also decayed gradually.In addition, because the result of immunity variation, aging skin also is easier to occur anaphylaxis and skin irritation.
More deep discussion molecular biology: weaken year by year because DNA and RNA pass to the message of skin growth, Skin Cell can't recover to copy vigorous situation as at an early age, will begin to occur obviously aging.The ability variation of skin moisturizing is so that the sense of touch of skin has also changed.DNA and RNA message weaken may a lot of reasons, comprises inflammatory response that long-term ultraviolet injury, free radical cause etc.
When skin surface exsiccation or irriate, depression can appear in the surface, and this is so-called little microgroove.They can allow skin seem wrinkle, but little microgroove is not wrinkle, as long as use wetting agent just can improve.If extremely dry skin does not use wetting agent, even dry rubescent phenomenon also can appear, that be because intercellular substance impaired due to.Intercellular substance is comprised of glycerol, cholesterol, nature moisturizing factor, mucopolysaccharide and other water-retaining agent.Water can not recover the health of intercellular substance, and lubricant, oils and fats and nature moisturizing factor then have this function.Yet if let go unchecked or the skin cell serious aging, these little microgrooves will become wrinkle, just can not improve with wetting agent afterwards.
Avoid the over-drying microgroove that causes, should appropriateness and regular exfoliation removes the aging cell of skin surface, allow the cell of plentiful health manifest, the skin behind the exfoliation has the sensation of taking on an entirely new look.Protect skin at clean healthy skin with sun-proof, antioxidation, irritation product, keep the water holding capacity of skin with skin care products again, microgroove can't form naturally.
2. slow down the method-somatomedin of skin aging
Somatomedin is a kind of indispensable functional protein in the body, Main Function is after the accepter of cell surface is combined, irritation cell produces a series of cell proliferation and differentiation, normal cell wants hypertrophy that the stimulation of somatomedin is arranged, and different Skin Cells also needs the stimulation of specific somatomedin to accelerate to upgrade and regeneration.The skin growth factor can provide the skin nutrient; delay skin aging, promotion skin repair; it is the optimum activity composition of skin nursing; can control or the regulation of skin ager process; the protection damaged skin; delay skin aging, significant to the 26S Proteasome Structure and Function, the normal physiological activity of keeping skin and the metabolism that keep normal skin.If skin does not have the stimulation of somatomedin, can't be newborn.
Somatomedin is few at people's in-vivo content, but biological activity is high, has multiple important biological effect and physiological function.Multiple somatomedin is relevant with growth, division, differentiation, propagation and the migration of Skin Cell, and they can provide the skin nutrient, delay skin aging or promotion skin repair.Skin aging is the outward manifestation of human senility, is because endogenous and the coefficient result of composite factor such as exogenous.With advancing age, skin aging more and more obvious, main manifestations be xerosis cutis, coarse, wrinkle, tarnish, elasticity reduce, pale, lax, even atrophoderma, crowfoot cracks and senile plaque etc. appear.Solar radiation or other environmental factors also can cause skin aging and impaired, reduce skin activity.Aging appearance and the image that has not only affected human body of skin, but also the physiological function that has seriously hindered human body skin, even also can cause the serious pathologic of skin to change.Somatomedin is the optimum activity composition of skin nursing, can control or the regulation of skin ager process, and the protection damaged skin, delay skin aging, significant to the 26S Proteasome Structure and Function, the normal physiological activity of keeping body and the metabolism that keep normal skin.
With advancing age, somatomedin secretory volume in vivo also reduces gradually, skin aging more and more obvious, and that skin becomes is dry, coarse, wrinkle, tarnish, elasticity minimizing, pale, lax, even atrophoderma, crowfoot cracks and senile plaque etc. occur.In addition, with advancing age, the blood flow of skin also reduces gradually, and nutrient and oxygen are not easy to deliver to epiderm skin and corium, also can accelerate the aging of skin.
From 2000, the somatomedin that people begin some are had specific function added in the cosmetics skin care products, as: EGF, bFGF, aFGF, TGF-β.Wherein EGF (epidermal growth factor) and FGF use two kinds more widely, wish to reach the anti-ageing effect that smoothes away wrinkles, increases elasticity, delaying aging by the high activity of somatomedin.
So the continuous input research of past scientist wishes to see through special processing or processing procedure, expectation is found out and is more suitable for the somatomedin kenel that skin absorbs.Except the cutaneous absorption of molecular size range meeting of somatomedin, the source of somatomedin and concentration also are the important evidence that depends on its quality good and the bad.Somatomedin must see through after the gene recombinaton with antibacterial or yeast manufacturing, the source of strain and the concentration of synthesizing and purifying, the safety in the activity that all can affect somatomedin and the use.
Utilizing biotechnology to extract effective skin care products composition from natural product is the leading role of skin care products in recent years, especially the skin care products that comprises somatomedin, as with epidermal growth factor (Epidermal Growth Factor, EGF) with the skin care products such as fiber mother cell growth factor (Fibroblast Growth Factors, FGF).
Yet somatomedin mainly comes from fermentation, extraction in the materials such as cattle and sheep Placenta Hominis, serum extraction, baby's foreskin or escherichia coli, and purity is generally less than 70%, the more easy allergy of impurity, and the source is not clear, easily has disease to infect and the residual risk of endotoxin.Even so, but units up to ten thousand easily of one bottle of the somatomedin skin care products of on the market import.
In addition, the protein that somatomedin is comprised of aminoacid, general molecular weight is all greater than 6.2kD, but the receptible molecular weight of human body pore is below the 3kD, present external existing experiment confirm just can enter skin less than 3kD and play a role.Therefore, the somatomedin that comprises the major part such as fiber mother cell growth factor all can't enter skin corium because molecular weight is too large and play a role.
3. slow down the method for skin aging-weak point and win peptide
The source of obtaining because of somatomedin is animality, use somatomedin may have the doubts such as skin allergy, inflammation, red and swollen suppuration, so the short peptide that wins in the streets, for example: Wushengtai (500Dalton), Argireline (600Dalton), just can be popular; Although it is shorter to win peptide, and its biological activity can not show a candle to somatomedin, and is shorter because winning peptide, is absorbed by the skin easily, therefore still helpful to skin elasticity.
In the market more well known two kinds win peptides be Wushengtai (Palmitoyl Pentapeptide 3, MatrixylTM) with Argireline (Acetyl Hexapeptide 3,
Wushengtai is the raw material that French SEDERMA company produces, and mainly is to form a fat-soluble victory peptide by five amino acid and Palmic acid, and experiment in vitro shows the function of strengthening the 4th type (Type IV) collagen protein synthesis.Argireline then is the raw material that Spain LIPOTEC company produces, and is called again the Argireline element, its effect of therefore named think of justice be similar to injection Botox (Botulinum Toxin,
The mechanism of utilizing its block nerves Transmitter acetylcholine (acetylcholine) to discharge suppresses the contraction of muscle, reaches the effect of eliminating dynamic lines.
No matter be Wushengtai or Argireline, it not existing aminoacid sequence structure in the human body, but by the molecule of the synthetic gained of science and technology, Wushengtai whether can be single-minded to skin corium fibroblast (fibroblast) and effectively produce excitation and Argireline whether can the block nerves conduction, still lack complete its effect of Experiment and clinic presentations test proof at present.According to above-mentioned, the skin care products that has desalination microgroove and increase skin elasticity concurrently is the problem that beauty treatment industry wish solves always.
For instance, on the market for prevention or improve cutis laxa and wrinkle two large classes victory peptides are arranged, a kind of is to reach by physical property to allow immediately consolidation of skin, but this mode can't really solve the lax problem of skin aging, and the time that therefore can keep skin-tightening is quite short.Another kind is the Main Ingredients and Appearance collagen protein that replenishes skin corium, it is to utilize to win peptide compounds to promote the collagen protein hypertrophy, winning peptide compounds is the above aminoacid that form of two aminoacid, is commonly referred to as and wins peptide or polypeptide, and its effect is different from putting in order according to the aminoacid classification that forms.Generally speaking, the aminoacid quantity that wins peptide is few, and molecule is little and enter easily skin, and easily synthetic, cost is also lower, but when the aminoacid quantity of victory peptide very little the time, can't form stereochemical structure and not have protein active, such as palmitoyl tripeptide 3, Wushengtai or Argireline etc. all be; Otherwise when the aminoacid quantity that wins peptide was too many, molecule can't enter skin too greatly again, can't reach beauty functions.
So far at present have following disappearance about the known techniques of slowing down skin aging: 1, the growth factor molecule amount is too large, can't be via smearing the skin effect that enters; 2, somatomedin mainly comes from fermentation, extraction in the materials such as cattle and sheep Placenta Hominis, serum extraction, baby's foreskin or escherichia coli, and purity is generally less than 70%, the more easy allergy of impurity, and the source is not clear, easily has disease to infect and the residual risk of endotoxin; 3, the somatomedin price is very expensive; 4, somatomedin has the possible doubt of carcinogenic and other side effect; 5, the activity of somatomedin is difficult for preserving; 6, win peptide ammino acid quantity very little the time, can't form stereochemical structure and do not have protein active; 7, winning peptide is not existing aminoacid sequence structure in the human body, but by synthetic point of science and technology, whether Wushengtai can block nerves conduct effect and the Argireline of skin corium fibroblast, still lacks complete its effect of Experiment and clinic presentations test proof at present.
Summary of the invention
Because the somatomedin of present known beauty treatment usefulness is the animality source, therefore be easy to cause allergic symptom, can have a negative impact for health, if with palmitoyl tripeptide 3, Wushengtai or Argireline replace, then its beauty treatment effect is not good again, therefore the present invention develops and synthetic a kind of can promote the medical cosmetology of cell new life and delaying human body skin aging to win peptide more, synthesized by 13~20 specific amino acids, its molecular weight is about 2.4KD, be of moderate size, can be via smearing the skin effect that enters, and should beauty treatment win that peptides are active to be preserved easily more, add in the product at normal temperatures through still having activity more than 24 months, can reach the effect of beauty treatment.
Slow down skin aging and mainly contain following mechanism:
1, naturality is aging follows the aging of whole body organ to carry out synchronously, keeps the life of rule, and joyful mood, balanced diet, sufficient sleep, suitable motion are the only effective means of anti-natural cause aging.
2, moisturizing: skin moisturizing ability and day, decrescence the skin hydropenia caused ductility to reduce, and cutin is piled up, microgroove occurs, and smearing moisturizer is the task of top priority.Commercially available moisturizer is various, and effect quality gap is quite large, and on the whole effect can be divided into four: 1) direct airtight epidermis, do not allow water evaporates; 2) have and absorb in the atmosphere moisture content in the ability of epidermis; 3) replenish the nature moisturizing factor that disappears on the skin; 4) provide the composition that prevents that skin moisture scatters and disappears.
3, the skin care products of activation aging skin regeneration: by regeneration skin corium structure, can have concurrently improve that cutis laxa is aging, microgroove, the dark Shen of the colour of skin.
4, check melanin: ultraviolet not only can generate by stimulation melanin, more may cause human body skin to become pitch-dark, thick and do, wears out, and impels easily skin aging ahead of time, the last even skin carcinoma of deriving.Therefore check melanin is the injury of prevention photoaging.
The present invention develops synthetic beauty treatment polypeptide can be increased simultaneously skin elasticity, suppresses dark red pigment and increase skin from the master lock outlet capacity.
