And that includes molecules in the dermis like elastin and collagen, creating tangled clumps or breaking them down.

So retinoids can help maintain the structure of your dermis and fight off wrinkles by making your body produce more collagen, elastin, and GAGs.

类维生素 A 能促使身体产生更多胶原、弹性蛋白和糖胺聚糖，从而有助于保护结构，抵抗皱纹。

Some of the ink particles are also suspended in the gel-like matrix of the dermis, while others are engulfed by dermal cells called fibroblasts.

有些颜料颗粒悬浮在胶质的结构，而其它颜料颗粒被叫做成纤维细胞的细胞吞噬。

The needles punch through the epidermis, allowing ink to seep deep into the dermis, which is composed of collagen fibers, nerves, glands, blood vessels and more.

针刺透表让颜料深入，之下是胶原纤维、经、腺体、血管等等。

These microbes, which include bacteria and fungi, thrive in the sebum, an oily substance that's secreted onto the skin's surface by sebaceous glands nestled inside the dermis.

包括细菌和菌的这些微生物，在脂内十分活跃，也就是由紧贴在内的脂腺分泌到肤表面的油性物质。

Made up of three layers, the epidermis, dermis, and hypodermis, skin's thickness varies from 0.5 millimeters at its thinnest and up to four millimeters at its thickest.

表层，层和下组织。肤最薄处为0.5mm，最厚处为4mm。

These microbes, which include bacteria and fungi, thrive in the sebum, an oily substance that’s secreted onto the skin’s surface by sebaceous glands nestled inside the dermis.

这些微生物（包括细菌和菌）在脂大量繁殖，脂是一种油性物质，由位于内的脂腺分泌到肤表面。

Made up of three layers, the epidermis, dermis, and hypodermis, skin’s thickness varies from 0.5 millimeters at its thinnest and up to four millimeters at its thickest.

肤由表、和下组织三层组成，厚度从最薄的 0.5 毫米到最厚的 4 毫米不等。

As these cells travel through the lymphatic system, some of them are carried back with a belly full of dye into the lymph nodes while others remain in the dermis.

当这些细胞在淋巴系统运动，有一部分携带着大量颜料进入淋巴结，另外一些依然留在表之下。
