Description
技术领域
本发明涉及皮肤护理技术领域,尤其涉及一种可迅速补充及促进表皮内源性成分生成的高效屏障修复组合物及其应用。
背景技术
皮肤是人体最大的器官,它被覆盖于整个人体表面,总面积为1.5-2m2,占人体总重量的5%。皮肤厚度为0.5-4mm,最外层是表皮,它由5层角质形成细胞组成,分别为角质层、透明层、颗粒层、棘层、基底层。角质层在表皮最外层由20层左右已死亡扁平无核的角质细胞所构成,正常皮肤角质层含水量为20%-35%,如果低于10%,皮肤屏障功能就会受损。许多皮肤病如老年性皮肤瘙痒、特应性皮炎、银屑病以及干燥性皮肤等都与皮肤屏障功能下降有关,因此保湿对于皮肤来说是至关重要。
随着研究的深入,人们开始越来越清楚的意识到皮肤护理的核心问题就是能否更好的维持角质层屏障保护功能的问题,当角质层屏障功能稳定时,皮肤就会显示良好的健康状态。目前的皮肤屏障修复方法主要是通过外涂油脂封闭保湿剂、亲水基质吸湿保湿剂、水合保湿剂等外源性保湿剂将水分保留在皮肤上,如发明专利CN201610216262.0“一种修复皮肤屏障的组合物”公开的一种修复皮肤屏障的组合物,该组合物按重量百分比由下述原料制成:透明质酸钠0.1%-1%,海藻糖0.5%-3%,保湿剂5%-25%和水71-94.4%,虽然通过外源性补充保湿剂可以快速达到保湿效果,一定程度上缓解因皮肤屏障损伤所带来的红肿、热痛、褪皮、瘙痒等症状,但仅能达到短暂的缓解皮肤的不适,并不能根本、长效改善皮肤屏障,要开发高效的屏障修复组合物,不仅需要为表皮迅速补充皮肤修复所需必需的养分,更需要刺激皮肤内源性修复成分的生成,通过关注角质屏障的形成过程及皮肤更深层面与保湿相关的组成,针对这些靶点使它健康表达,才能真正意义上改善皮肤屏障,达到高效修复的作用。
发明内容
本发明的一个目的在于提供一种可迅速补充及促进表皮内源性成分生成的高效屏障修复组合物,本发明的组合物包含外源性修复成分补充剂及内源性成分生成促进剂,其中,外源性修复成分补充剂由类皮肤脂质复合物、宽谱透明质酸钠、多氨基酸多糖缩合物复配而成,能从表面迅速补充皮肤修复所必需的养分,内源性成分生成促进剂由水解羽扇豆蛋白、麦冬根提取物、水解三色堇提取物、酵母提取物复配而成,可刺激表皮自身内源性修复成分的生成,利用各种成分合理组合、配合共用,通过外补充、内刺激的机理达到安全、高效的保湿、屏障修复的效果。
本发明的另一个目的在于提供上述高效屏障修复组合物在制备用于修复和/或预防皮肤屏障损伤的药物和/或化妆品中的应用。
本发明的上述目的通过以下技术方案实现:
一种高效屏障修复组合物,其特征在于,包含外源性修复成分补充剂以及用于促进皮肤生成内源性修复成分的内源性成分生成促进剂,所述的外源性修复成分补充剂包括类皮肤脂质复合物,所述的内源性成分生成促进剂由水解羽扇豆蛋白、麦冬根提取物、水解三色堇提取物、酵母提取物组成。
作为本发明的一种优选实施方式,所述的内源性成分生成促进剂由以下重量份组分组成:水解羽扇豆蛋白:0.50~7.00重量份;麦冬根提取物:0.50~4.00重量份;水解三色堇提取物:0.50~5.00重量份;酵母提取物:0.50~4.00重量份。
作为本发明的一种优选实施方式,所述的外源性修复成分补充剂由以下重量份组分组成:类皮肤脂质复合物0.20~5.00重量份;宽谱透明质酸钠0.001~1.00重量份;多氨基酸多糖缩合物0.50~6.00重量份。
作为本发明的一种优选实施方式,本发明所述的类皮肤脂质复合物可为市售的一款类皮肤生理脂质成分的复合物。
作为本发明的另一种优选实施方式,本发明所述的类皮肤脂质复合物也可为自制组分,所述的类皮肤脂质复合物由如下按质量百分比计的成分组成:
神经酰胺3 3.5%;C8-12酸甘油三酯0.3-3.0%;胆甾醇0.5-5.0%;氢化卵磷脂0.2-2.0%;植物鞘氨醇1.5%;硬脂酸0.5-5.0%;油酸0.2-2.0%;乳酸0.2-2.0%;余量为水,其中神经酰胺3是属于微生物发酵获取的中性神经酰胺3,与皮肤有更好的亲和力。
已知皮肤角质层的脂质组成为:40%神经酰胺、25%胆固醇、25%游离脂肪酸,其中还含有部分的植物鞘氨醇、神经鞘氨醇和二氢神经鞘氨醇。皮肤的屏障功能由角质层细胞间的类脂薄层提供,其中神经酰胺在其中发挥着重要的作用。我们通过复配含有与人体皮肤结构相同的神经酰胺以及油脂的复合物(即类皮肤脂质复合物),来模拟真实皮肤角质层中的类脂结构,从而可以渗透到皮肤深层,我们要做的就是模拟人体皮肤角质层的类脂构成,达到更好的修护皮肤屏障的效果。
可是就算是科学家也不可能做出100%与人体细胞分泌一致的细胞间脂质,因此需要加入促进细胞间脂质自身主动合成的组分,达到互补的效果,基于此,本发明经多次试验,在本发明组合物中添加水解羽扇豆蛋白。
本发明优选的水解羽扇豆蛋白为市售水解羽扇豆蛋白,水解羽扇豆蛋白是一种来自白色甜羽扇豆的植物活性成分,富含低分子量谷氨酰胺肽和寡糖,具促进结构蛋白和表皮脂类的合成;促进角质层细胞间隙主要脂类(神经酰胺、胆固醇、甘油二酯和三酯)的合成;渗入表皮基底层,刺激此处细胞活性,激活角质形成细胞分化,确保角质层更新,维持角质层的完整性;增强皮肤的天然重建系统,减少水分流失,重建皮肤屏障功能。
高分子量的HA能够较好地形成水化膜,而其进入皮肤能力欠佳,低分子量的HA成膜性较差,但其渗透能力显著,本发明优选的宽谱透明质酸钠为市售透明质酸钠纯粉末,分子量为50~3000KDa,是一个完整分子量宽度的透明质酸钠,因此它不是关注于某一特定分子量的功效,而是关注完整分子量宽度的相互协同作用,如同我们人体天然的透明质酸一样,更高效、更安全,作用于皮肤时具有特定的细胞学过程(稳态或应激态)。
可是就算是最易渗透的透明质酸钠,也会存在生物利用度的问题,外补不如内生,因此需要加入促进透明质酸内源性合成的组分,达到互补的效果。
透明质酸(HA)是一种粘多糖,可在真皮细胞间质中找到,起到绑定水分和电解调控的作用,也能促进角质形成细胞新陈代谢,并在细胞外分泌,能够促使水和养分扩散。透明质酸并不单纯充盈空间,同时也锚定受体蛋白CD44(细胞粘附分子)。透明质酸参与角质形成细胞增殖和分化,在基底层,透明质酸活化角质形成细胞和板层体的形成。因此,透明质酸是一个关键的水相关分子,关系到皮肤的防水屏障。
作为本发明的一种优选的实施方式,本发明中的酵母提取物为市售酵母提取物,富含来自墨西哥龙舌兰叶的酵母低聚糖,通过提升透明质酸合酶(HAS2)合成酶的表达,重新激活自然下降的透明质酸合成机制。皮肤因透明质酸同他们的细胞受体CD44的特殊相互作用表现出一种规律,这种规律使得细胞具有“感知”微环境的能力并通过信号传导或细胞骨架动态调节来回应外界刺激。HA-CD44的交互作用促进了角质形成细胞终生的持续再生,从柱状基底细胞分裂时,并中止于角质细胞扁平化。
另一方面,本发明的内源性成分生成促进剂还包括水解三色堇提取物,水解三色堇提取物是一种来自野生三色堇富含寡糖的活性成分,它通过两种调节机制,发挥对角质层水分内稳定的调节功能:1)流通:通过刺激嵌入在细胞膜脂质层内的水分流通——水通道蛋白-3的合成,来改善真皮到表皮的水循环;2)驻留:通过促进补充表皮透明质酸和受体蛋白CD44(存在于角质形成细胞表面的一种跨膜糖蛋白,是透明质酸在角质形成细胞表面的重要受体,能够将其固定在细胞外基质中,发挥生物学效应)的合成,增加透明质酸合成酶-2的含量,来提高表皮保留水分的能力。这种旨在维持流通与驻留间的理想平衡的肌肤保湿方法,能够发挥对表皮的强效保湿,维持肌肤的柔软度和可塑性。
作为本发明的一种优选的实施方式,本发明中的多氨基酸多糖缩合物为市售的多氨基酸多糖缩合物,其分子量约为20000道尔顿,是从玉米中提取,根据色谱吸附分析法从玉米中精炼结晶的纯天然物质,含小分子的氨基酸(甘氨酸、谷氨酸,亮氨酸,脯氨酸,赖氨酸、苏氨酸、蛋氨酸和胱氨酸等)、肽、核苷酸、维生素及大分子的多糖(主要葡萄糖、果糖、木糖、阿拉伯糖4种单糖聚合而成)等天然活性成分。氨基酸是皮肤角质层中自然保湿因子(NMF)的主要成分,易被皮肤吸收,使老化的表皮恢复弹性,延缓皮肤衰老;核酸及核苷酸是人体的主要遗传物质,具有促进新陈代谢、提高蛋白质合成速度等作用,增强免疫机能、增强SOD活性,提高皮肤抗自由基能力;多糖大分子结构能充分锁定水分子,提高保湿性能,有效降低皮肤粗糙度。此外还含有少量的维生素和矿物质等营养元素还可以为皮肤提供充足的营养。
作为本发明的一种优选的实施方式,本发明中的麦冬根提取物富含纯化的麦冬果聚糖,可为市售产品,通过麦冬的块茎中纯化取得,麦冬起源于亚洲,因为麦冬的块茎含有粘多糖所以它有很好的锁水性能,在中国传统医学上广泛使用。麦冬根提取物所含麦冬果聚糖可增加Claudin-1(形成紧密连接所必需的跨膜蛋白)和Zonula Occludens-1(闭锁小带蛋白-1)合成,形成紧致连接网络和提高角质层NMF(天然保湿因子)的水平,改善表皮上层的附着力,从而激活表皮脂质合成,并优化其组织,加强表皮连接,重组皮肤的屏障功能。Claudin-1和Zonula Occludens-1是主要的紧密连接蛋白,在细胞间连接和屏障功能平衡方面发挥着重要作用。因此,麦冬根提取物通过在角质层提高肌肤表面NMF含量,在颗粒层促进细胞紧密连接,减少水分流失,从而达到重建皮肤屏障的作用。
本发明通过内源性成分生成促进剂与外源性修复成分补充剂相互配合,相辅相成,既能较全面的从肌肤表面迅速补充皮肤修复所需必需的养分,又能刺激皮肤内源性修复成分的生成,这种外补充内促进自然生成的作用机理能高效及时的缓解脆弱的皮肤屏障所引起的不适,又能实现真正的修复皮肤屏障。
作为本发明的一种优选实施方式,所述的内源性成分生成促进剂由以下重量份组分组成:水解羽扇豆蛋白:3.00~5.00重量份;麦冬根提取物:1.00~3.00重量份;水解三色堇提取物:2.00~4.00重量份;酵母提取物:2.00~4.00重量份;所述的外源性修复成分补充剂由以下重量份组分组成:类皮肤脂质复合物3.00~5.00重量份;宽谱透明质酸钠0.1~0.4重量份;多氨基酸多糖缩合物3.00~5.00重量份。
本发明还提供上述高效屏障修复组合物在制备用于修复和/或预防皮肤屏障损伤的药物和/或化妆品中的应用,所述组合物在药物和/或化妆品中的添加量为至少3%。
本发明的高效屏障修复组合物可直接施用于皮肤表面,也可以进一步用于生产化妆品/药物再施用于皮肤表面,达到高效修复肌肤屏障损伤的效果,恢复健康肌肤。
作为本发明的一种优选实施方式,所述药物和/或化妆品还包含有化妆品或皮肤病学上常用的外用制剂基质及水,所述的化妆品或皮肤病学上常用的外用制剂基质包括抗过敏剂、抗氧化剂、螯合剂、乳化剂、油脂、润肤剂、保湿剂、表面活性剂、肤感调节剂、增稠剂、防腐剂、螯合剂、香精中的一种或多种。
本发明的有益效果在于:
本发明既能较全面的从肌肤表面迅速补充皮肤修复所需必需的养分:类皮肤脂质复合物(神经酰胺3、C8-12酸甘油三酯、胆甾醇、氢化卵磷脂、植物鞘氨醇、硬脂酸、油酸、乳酸、水)、宽谱透明质酸钠(透明质酸钠)、多氨基酸多糖缩合物(小分子的氨基酸、肽、核苷酸、维生素及大分子的多糖);又能刺激皮肤内源性修复成分的生成:水解羽扇豆蛋白(促进角质层细胞间隙主要脂类的合成,激活角质形成细胞分化,维持角质层的完整性)、酵母提取物(激活透明质酸合成机制)、水解三色堇提取物(刺激嵌入在细胞膜脂质层内的水通道蛋白-3的合成、促进表皮透明质酸和受体蛋白CD44的合成,增加透明质酸合成酶-2的含量,强效保湿)、麦冬根提取物(在角质层提高肌肤表面NMF含量,在颗粒层促进细胞紧密连接,重建皮肤屏障),内源性成分生成促进剂与外源性修复成分补充剂相互配合,相辅相成,这种外补充内促进自然生成的作用机理能高效及时的缓解脆弱的皮肤屏障所引起的不适,又能实现真正的修复皮肤屏障。

表2乳酸刺痛试验结果对比
结合表2所示的乳酸刺痛试验结果对比以及图1所示的乳酸刺痛试验结果对比图,可清晰看出:
短期改善乳酸刺激:实施例1>对照样2>对照样3>对照样1
长期改善乳酸刺激:实施例1>对照样3>对照样2>对照样1
本发明实施例1能实现快效+长效改善皮肤的耐受性,比单一的补充(对照样2)或促生成(对照样3)修复屏障的效果要好,要快。
角质层含水量(%):皮肤水分含量,其值越大,水分含量越大,反之,水分含量越小。
时间(天) | 实施例1 | 对照样1 | 对照样2 | 对照样3 |
0 | 44.1±15.3 | 43.9±15.7 | 43.6±14.9 | 44.2±14.8 |
3 | 50.8±13.2 | 44.3±14.2 | 47.8±14.6 | 46.5±13.8 |
7 | 53.6±12.4 | 45.6±14.3 | 49.6±13.6 | 48.3±13.9 |
14 | 57.8±12.8 | 46.7±13.8 | 51.4±13.3 | 51.7±13.4 |
28 | 60.6±12.5 | 48.5±14.3 | 52.8±13.9 | 54.3±14.5 |
表3角质层含水量变化
结合表3所示的角质层含水量变化以及图2所示的角质层含水量变化对比图,可清晰看出:
短期补充角质层含水量:实施例1>对照样2>对照样3>对照样1
长期改善角质层含水量:实施例1>对照样3>对照样2>对照样1
本发明具有良好的快效+长效的改善角质层含水量的效果。对照样2:直接从外部迅速补充皮肤修复所需的养分,对照样3:因为没有进行外部的补充所以不能迅速的缓解角质层的缺水。所以只有从外部迅速缓解角质层的缺水同时促进皮肤自身内源性修复成分的生成才能真正的改善角质层含水量。
TEWL值(g·cm-2·h-1):是皮肤屏障好坏的一个重要标志,皮肤的TEWL值越低,说明皮肤的屏障功能就越好,反之,则越差。
时间(天) | 实施例1 | 对照样1 | 对照样2 | 对照样3 |
0 | 20.6±5.4 | 20.7±5.6 | 21.1±5.3 | 20.4±5.7 |
3 | 17.7±5.1 | 20.2±5.5 | 18.3±5.6 | 18.9±5.6 |
7 | 15.6±5.3 | 19.7±5.2 | 17.2±5.2 | 17.6±5.4 |
14 | 13.9±5.6 | 18.9±5.1 | 16.9±5.7 | 15.9±5.6 |
28 | 12.5±5.8 | 18.2±5.7 | 16.2±5.6 | 14.8±5.3 |
表4 TEWL值变化
结合表4所示的TEWL值变化以及图3所示的TEWL值变化对比图,可清晰看出:
短期TEWL值的快速改善:实施例1>对照样2>对照样3>对照样1
长期TEWL值的改善:实施例1>对照样3>对照样2>对照样1
本发明具有良好的短期快效+长效修复皮肤屏障的功效。对照样2:直接从外部迅速补充皮肤修复所需的养分,对照样3:因为没有进行外部的补充所以不能迅速的降低皮肤的TEWL。所以只有从外部迅速缓解角质层的缺水同时促进皮肤自身内源性修复成分的生成才能真正的改善皮肤的屏障。
试验结束后,实施例1、对照样1、对照样2以及对照样3四组受试者均未出现红斑和瘙痒,无刺激性症状出现,表明本发明实施例提供的高效屏障修复产品没有皮肤刺激等安全性问题。
同时95%以上的实施例1受试者反馈,本发明提供的高效屏障修复产品具有良好的润肤作用,在短时间内明显改善干燥脱皮现象,长期使用不但能提高皮肤的耐受度而且使皮肤水润饱满、光滑水嫩并且有一定的淡化皱纹,使皮肤光滑有弹性的功效。
虽然本发明已以实施例公开如上,但其并非用以限定本发明的保护范围,任何熟悉该技术的技术人员,在不脱离本发明的构思和范围内所作的更改与润饰,均应属于本发明的保护范围。
