胶原蛋白的好处:不仅仅是吃或涂抹

Skin Confidence Filled with Collagen

在讨论护肤时,总有一个词被提及,如同包治百病。它是一种神奇的成分,用于护理、涂抹于面部,甚至直接食用。尽管其确切的作用和功效可能尚未完全了解,但每个人都相信它对皮肤有益,因此人们会将其纳入日常护肤流程。这种成分就是胶原蛋白。关于胶原蛋白益处的文章不胜枚举,而用于食用和使用胶原蛋白的产品也不断涌现。


Interest in collagen is increasing by the day. The market for consumable collagen is expected to reach a scale of 10 trillion KRW by 2030. What’s fascinating is that, at the same time, debates about the effectiveness of collagen have been ongoing for a long time. So, let’s clarify what collagen actually is and how to effectively boost it.



Before discussing the benefits of collagen, let's define it.

胶原蛋白是一种蛋白质。虽然它通常与皮肤有关,但它是一种多功能蛋白质,在骨骼、肌肉、血管和牙齿等各种结缔组织中发挥作用。胶原蛋白占人体蛋白质总量的25-35%,这凸显了它的重要性。


What we should focus on is the relationship between the skin and collagen. Beneath the epidermis, which is the outer layer of the skin, lies the dermis. Collagen makes up 70-90% of the dermis. In the dermis, collagen forms a network-like structure, serving the role of maintaining the skin’s shape, much like the rebar in a building.


坚实的地基是建造安全耐用建筑的必要条件。建筑争议中经常出现的问题是钢筋的缺失。皮肤也是如此。为了保持紧致的皮肤,作为支柱的胶原蛋白必须密集存在。胶原蛋白还具有吸收水分的能力,帮助皮肤保持水润。



胶原蛋白为何重要?它有哪些益处?

与构成身体的所有元素一样,胶原蛋白也有寿命。当出现缺口时,新产生的胶原蛋白就会填补。问题始终在于年龄。随着年龄的增长,胶原蛋白会直接受到影响。不仅新胶原蛋白的生成速度会下降,其总量也会减少。


What does a decrease in collagen levels mean for the skin? Let's take a houseplant as an example. When a plant grows to a certain size, it can no longer support its weight and begins to tilt. If left unattended, its structure may collapse and it will wither quickly, so a support stick is used. The support keeps the plant upright, much like collagen. Now, imagine removing these supports one by one. The once-firm stem begins to droop. The same happens with collagen. As the collagen that supported the skin gradually diminishes, the skin loses volume and wrinkles form. This change is especially noticeable around the under-eye area, cheeks, jawline, and neck.


现在你可能明白了。管理胶原蛋白不仅对保湿至关重要,也是保持肌肤紧致的基础。如果胶原蛋白得到有效管理,就能促进整体肌肤健康。



Is the Effectiveness of Collagen Supplements Real?

你可能听说过猪皮、猪蹄和鸡爪富含胶原蛋白。虽然听起来难以置信,但这却是事实。问题在于,这些胶原蛋白能否被有效吸收。仅仅摄入胶原蛋白并不意味着它就能直接到达你的皮肤。


When we ingest something, it inevitably passes through the digestive system. This applies to both pig skin and collagen supplements. Collagen, after going through the digestion process, is broken down into smaller components like amino acids. These are absorbed by the body, used as energy, or utilized in various forms by different organs. This means collagen doesn’t go directly to the skin.



那么,目前引领胶原蛋白潮流的低分子胶原蛋白呢?低分子胶原蛋白的原理是将其分解成更容易被人体吸收的尺寸。与通过食物摄入相比,低分子胶原蛋白的吸收率可能更高,但事实上,它并非仅仅直接作用于皮肤。因此,目前尚不清楚是否有足够多的胶原蛋白能够到达皮肤并显著增加胶原蛋白的合成,这方面还需要更多的研究。


总而言之,口服胶原蛋白补充剂确实有可能对皮肤产生积极作用。然而,它们能否带来切实可见的效果仍是一个悬而未决的问题。



The Effectiveness of Topical Collagen: Even You?

如今,注入胶原蛋白的化妆品随处可见,从安瓶、面霜到面膜,应有尽有。但涂抹这些产品真的能补充胶原蛋白吗?答案是否定的。这是因为胶原蛋白无法渗透皮肤。


皮肤有一条规则,叫做“500 道尔顿规则”。道尔顿是分子量的单位,一种物质要想被真皮层吸收,其分子量必须低于 500 道尔顿。现在,你可能想知道胶原蛋白的分子量是多少道尔顿。胶原蛋白的分子量接近 10 万道尔顿。皮肤就像一道保护屏障,如果胶原蛋白能够穿透,各种杂质就会进入皮肤。


有些人可能会声称使用胶原蛋白产品确实见效。虽然胶原蛋白类化妆品确实可以改善肤质,但如前所述,胶原蛋白具有吸水的特性。保湿效果可以使肌肤感觉饱满水润。然而,这与胶原蛋白是否真的通过化妆品在皮肤中生成是两个不同的问题。
