Skin = Health?

When we talk about physical health, we think of detoxifying our kidneys or doing cardio for a healthy heart—but what most people don’t realize is that skincare plays a huge role in our physical health!

In fact, skin is the largest organ of our body, as well as our immune system’s primary defense against dirt, illness, and disease.

It’s well-known that skin is one of the first and most telling markers of poor health. Lack of sleep leads to dull skin, while dehydration can cause dryness and breakouts. But skin is more than just vanity or a harbinger of health doom: skin health is essential to keeping the rest of our body healthy, too.

Unhealthy skin is more susceptible to infection, allowing bacteria to enter the body and multiply. On the other hand, healthy skin cells combat UV damage, help regulate hydration, and prevent cancerous cell carcinoma.

Understanding Our Skin

The skin is made up of three main layers: the 表皮, 真皮和 皮下組織 (or the “superficial fascia”). Each layer of the skin has a different—though equally crucial—function in healing, regenerating, and keeping our skin healthy.

表皮 is the outermost layer of the skin, with “epi-” meaning “upper” or “over” and “dermis” meaning “skin.” Distributed across the epidermis are 退黑激素, which dictates our skin tone, and 角蛋白, which defends against environmental irritants. Epidermal skin cells, also called squamous cells, are continuously shed and regenerated to form a waterproof moisture barrier that locks in hydration.

As it lies directly underneath the epidermis, the 真皮 is often called the “true skin.” The dermis is a major 膠原 和 彈性 storage source: these two major proteins keep our skin smooth, elastic, and supple. Home to the skin’s blood vessels and 淋巴系統, the dermis helps to heal wounds and deliver nutrition to the epidermis. Sebaceous glands, which produce 皮脂, a waxy substance responsible for skin moisture and oiliness, are also located here.

Every time you sit on a hard surface, you’ve got your 皮下組織 to thank! The hypodermis is also known as the subcutaneous layer, which means “under the skin.” Fittingly, it’s a layer of 體內脂肪 and connective tissue located under the dermis that absorbs shock: think of it as a protective pillow between sharp bone and delicate skin. This is also where our 汗腺 reside, making the hypodermis doubly crucial for 調節體溫.

To balance hydration

Hydrated skin is healthy skin! From oil production to texture and suppleness, keeping your epidermis and dermis hydrated is key.

• Boost moisture levels with 透明質酸 和 雪菇 extract in the 雙重透明質酸抗氧化精華
• Lock in hydration with Olive Fruit Oil in the 煥光高效保濕乳

To rejuvenate aging skin

Collagen production in the dermis slows with age. Combined with sunlight, pollution, and dry air-conditioning, this can cause dullness and fine lines. 

• Restore collagen and brighten dark circles with 植物萃取角鯊烷 ，詳見 煥光修護精華油
• Refine sagging skin and erase wrinkles with the 玫瑰粉晶刮痧板 (learn about the benefits of rose quartz and traditional Gua Sha 請點擊這裡!)
