The Science Behind Dry Skin: How it Affects Your Skin Barrier

Our skin is the body's largest organ and plays a crucial role in protecting us from environmental threats. One of the key elements that contribute to its effectiveness as a barrier is its moisture content. Multiple layers of cells, proteins, carbohydrates, acids, lipids, or fats, make up our skin. Ceramides and other lipids in particular serve as the structural glue for the body. Together, these elements help stop water loss via the skin and act as a barrier between the rest of your body and the environment.

Understanding the Skin Barrier

The skin barrier is composed of several layers, with the outermost layer called the stratum corneum.  The outermost layer of your skin, known as the skin barrier, is made up of lipids and cells. Keratin, organic moisturizers, cholesterol, fatty acids, and ceramides make up the lipid layer. The skin barrier is in charge of preventing infections and poisons from entering your body and upsetting its delicate equilibrium. Most notably, it aids in skin and internal body water retention. Skin that has been injured in these outer layers may seem dull and feel scratchy or dry. The essential compounds that maintain skin cells intact are lost or made impossible to hold onto when the protective barrier is compromised.

Why is the Skin Barrier important?

The skin barrier is crucial because it defends against external dangers such as allergies, pollutants, systemic toxicity, and infectious pathogens. However, our skin barrier is being harmed by our daily skincare regimens and external surroundings.


Several functions of the Skin Barrier:

  1. Moisture Retention - Internally, the skin supports homeostasis and guards against increased water loss from the body. Your skin barrier is a priceless ally that guards you from all the evil things in the world while also preserving water that is both priceless and vital to life. This helps maintain skin hydration, flexibility, and overall health.

  2. Protection - The skin barrier serves as a physical barrier against environmental factors including harmful microorganisms, chemicals, and UV radiation, reducing the risk of infections and skin damage.

  3. Temperature Regulation - It contributes to the regulation of body temperature by aiding in the management of sweat evaporation from the skin's surface.

  4. Sensory Perception - Nerve endings within the skin transmit sensory information, allowing us to perceive touch, temperature, and pain.

What is Dry Skin?

Dry skin, commonly known as xerosis, is a frequent condition. Your skin requires moisture to be soft and supple, but as we get older, it is harder to keep that moisture. In the cold, our skin also loses moisture more quickly. The lack of moisture causes the skin to become dry and itchy, which makes you want to scratch or rub, weakening the skin barrier even more. Insufficient synthesis of filaggrin can also affect the pH of the skin, allowing for aberrant bacterial development that may trigger allergic reactions.

Each of the three major layers of the skin has a distinct primary function.

1. The epidermis, which is compromised, serves as a barrier to stop the loss of fluid and electrolytes and to provide a defense against external insult or harm.

2. The dermis, which provides structural and dietary support

3. Insulation is provided by the hypodermis or subcutaneous fat layer.

The epidermis' primary job is to protect the skin from water loss and keep it moisturized.  Increased water loss and dry skin may be the results of barrier changes.  Lower skin cell cohesivity can result from disrupted desquamation. A compromised barrier function will also make it easier for items to penetrate the skin and cause irritating contact dermatitis. On a macroscopic level, dry skin might seem rough, uneven, flaky, cracked, or even fissured.  The skin may exhibit symptoms such as dryness, tightness, discomfort, soreness, or itching.  The combination of personal or environmental variables might also result in dryness.

How Dry Skin Develops

Many people suffer from dry skin. It occurs when the skin lacks the necessary amounts of water or naturally produced oils to sustain its own health and stay smooth and supple. Particles from the outside atmosphere can more easily penetrate thin skin. This explains why dry skin may itch.


Dry skin develops when the skin barrier is compromised, leading to increased moisture loss. Various factors contribute to this disturbance, including:

  1. Sebum, one of the skin's natural oils, aids in maintaining moisture. Dryness can result from conditions that cause less sebum production, like psoriasis and atopic dermatitis.

  2. The skin can lose its hydration and natural oils when exposed to harsh environmental factors including wind, sun, and low humidity.

  3. Prolonged exposure to hot water can weaken the skin barrier and deplete the natural oils in the skin.

  4. The pH balance of the skin can be disrupted and protective lipids removed when using harsh soaps and cleansers.

  5. As we age, our skin naturally becomes thinner and produces less oil, making it more susceptible to dryness.

Signs of Skin Damage

  • Acne.
  • Skin that is dry, scaly, or flaky.
  • Infection.
  • irritation and inflammation.
  • Itchiness.
  • rough areas.
  • stinging, particularly after using skin care products.
  • sensitivity or tenderness.

Restoring and Maintaining Skin Hydration

  • Water is essential for maintaining internal body and skin hydration.

  • Gentle Cleaning to prevent depriving your skin of its natural oils, use gentle, moisturizing cleansers.

  • Choose hyaluronic acid - ceramides, and glycerin-containing moisturizers to restore and seal in moisture.

  • Apply daily broad-spectrum sunscreen - to protect your skin from UV rays.

  • Avoid Harsh ingredients - watch out for skincare products that contain alcohol, perfumes, or other irritants that might weaken the barrier of your skin. Use natural and clean skincare in your daily regimen.

In conclusion, keeping healthy, pleasant, and radiant skin depends critically on the strength and integrity of the barrier function of our skin. A number of irritating and even painful skin conditions, ranging from minor irritation to more serious problems, can be brought on by dry skin and a damaged skin barrier. The barrier function of your skin must be prioritized if you want to achieve and keep attractive, healthy skin. You may take proactive measures to maintain your skin's hydration, resiliency, and radiance for years to come by comprehending the reasons and putting effective preventative measures in place.

Including Pure Culture products in your skincare routine may be a great way to achieve and maintain skin that is not only wonderfully nourished but also protected from environmental stresses and dryness. Pure Culture skincare items offer a chance for a skincare reset, with a fresh emphasis on creating a practical, kind, and efficient regimen.
