The Cornaline™ “French touch” keeps skin looking beautiful

Skin structure: Southeast Asian skins are different, but do you know why?

The skin is considered as an organ because it fulfills different vital functions and is the largest organ of the human body: it represents 16% of its total weight.

From a chemical point of view, the skin on average is made of :

- 70% water

- 27.5% protein

- 2% fat

- 0.5% of mineral salts and trace elements


The skin structure is composed of several layers of tissue, which forms a protective barrier for the body against the external environment, it limits dehydration and shelters the body from the sun’s rays.

But the skin also provides other vital functions as:

- perception and sensitivity, thanks to the many nerve endings it contains.

- thermal regulation by sweating

- synthesis of vitamin D under the action of solar rays

It has also a social role because it is a physical characteristic of each individual and because there is a relationship between the psyche and the immune system of the skin.

Let's discover together the structure of the skin

It is made of three layers of tissue:

  • the epidermis, the superficial layer
  • the dermis, intermediate layer
  • the hypodermis, deep layer

The epidermis is a semipermeable coating tissue, composed of three types of cells:

  • Keratinocytes, filled with keratin (a protein also used in the composition of hair and nails) and lipids
  • Melanocytes, which produce melanin responsible of the skin pigmentation
  • Langheran cells, which participate in the skin immune system

The epidermis divides itself into five layers.

  • The upper layer is called stratum corneum and its lower part constitutes a real barrier of protection against exogenous factors (pollution, sun, cold) and endogenous water loss.
  • The basal layer, the deepest layer ensures the continuous regeneration of the skin by cell division. Those cells migrate gradually to the upper layers undergoing various mutations. The melanocytes which are responsible for melanogenesis are in this layer

The dermis which supports the epidermis, protects the vascular network and nerve fibers. It has different types of cells:

  •  Fibroblasts which synthesize collagen, a protein essential to tissues elasticity
  • Cells, which play an important role in the skin immune reactions

The hypodermis is a tissue which has different functions:

  • Protector as a damper between the dermis and the bones
  • Thermal insulator
  • Morphological, as it shapes the silhouette according to the age, the sex, the nutritional state of the individual
  • Energetic, by the storage of fats.

Inside of the dermis and the hypodermis you find the glands which produce sweat, the ones responsible for body odor, the ones which secrete sebum, and hair.


Let’s see why Southeast Asian skin structure is different and what it needs.

  • Due to a thinner stratum corneum (the outermost layer of the epidermis), this skin type is less resistant to mechanical stress, therefore more sensitive to environmental aggressions and irritants (i.e. pollution) and more prone to scarring. Hence the necessity to provide your skin with a protective barrier against the effects of environmental stressors and pollutants.
  • Southeast Asian skins tends to have the highest rate of water loss (Transepidermal Water Loss). If skin loses moisture, it can become dry and appear scaly, itchy, red, and irritated. So it is important to limit water loss by an adapted cream.
  • Southeast Asian skin is much more prone to hyperpigmentation (melanin overproduction), which puts the skin at risk for melasma, freckles, and sun spots. Hyperpigmentation can be caused by sun damage, inflammation, or other skin injuries, including those related to acne. To avoid it, melanin production shall be controlled.
  • The increased presence of sebaceous gland results in excess oil, which can enlarge pores and make it easier for acne to develop. Humidity can also cause your oil glands to overact, resulting in unsightly shiny patches and increased acne. So regulate sebum production.
  • Here’s the good news! Southeast Asian skin actually ages at a slower rate, which is probably why you’ve been complimented on your youthful appearance. The secret is that Southeast Asian skin has a thicker dermis (the layer of skin that contains collagen and elastin). And the more collagen and elastin you have, the fewer wrinkles you get. But it’s important to use beauty products that take special care to preserve this innate anti-aging property.

At Cornaline, our mission is to bring an effective and simple answer to those issues.

The Day Cream protects your skin from environmental stressors like pollution and sun, and limits melanin production and water loss.

The Night Cream lessens the hyperpigmented areas, regulates sebum production, tightens the pores, and mattifies and equalizes your skin tone. It also acts against sagging, to take care of the natural anti-ageing property of your skin.
