What is Skin ?

The skin is the only organ that connects the inside of our body to the external environment around us. It plays a crucial role in interacting with the environment to protect us. It is also the largest organ of the human body. Here’s a simple and segmented explanation:

Functions of the Skin

  • Protection

Acts as a barrier against external aggressions (microbes, UV rays, pollution).

  • Thermal Regulation

Maintains body temperature through sweating and insulation.

  • Sensitivity

Contains sensory receptors that enable the perception of touch, pain, heat, and cold.

  • Vitamine D Production

Under the effect of sunlight, the skin synthesizes vitamin D, essential for bone health.

Main Layers of the Skin

  • Epidermis

The visible outer layer made of dead cells, which is regularly renewed. It contains melanocytes that produce melanin, the pigment protecting us from the sun and responsible for skin color and tanning. It also includes Langerhans cells, which ensure cellular immunity.

  • Dermis

The intermediate layer provides nutrition and hydration. It contains blood vessels, sweat glands, and hair follicles. Specifically, it is connective tissue made of fibroblast cells that produce protein fibers and essential substances such as collagen, elastin, and hyaluronic acid, which retain water.

  • Hypodermis

The subcutaneous part connecting the skin to bones, muscles, etc. This deep layer is mainly composed of fat, acting as a thermal insulator and protective cushion, giving the skin flexibility.

Skin Care

  • Regular Cleansing

Removes dirt, excess sebum, and accumulated pollution particles.
Use products suited to your skin type (e.g., our refreshing & purifying cleansing gel with altitude plants).

  • Hydration

Maintains the skin’s elasticity and barrier function.
Use a moisturizer rich in natural ingredients (such as hyaluronic acid or sweet almond oil) to deeply nourish the skin.

  • Sun Protection

Shields the skin from UV rays, the primary cause of premature aging and spots.
Apply sunscreen daily with an appropriate SPF, even on cloudy days.

Conclusion

The skin is not just a "covering"; it also reflects your overall health and habits. Take care of it by drinking enough water, adopting a balanced diet, and avoiding stress as much as possible with good lifestyle habits.
