Causes of Dry Skin

Causes of Dry Skin

Almost everyone has dry skin at some point. Ageing, cold climates and chemical irritation all contribute to dry skin.

Dry skin, or dryness, is a common skin condition that affects people of all ages and can appear on different parts of the body. The skin needs a constant moisture content of 10-15% to maintain its condition and elasticity. Hence low moisture content negatively affects the elasticity of the skin. But what causes dry skin and how does it affect the skin?

Dry skin can cause itchiness, which can later lead to abrasions and even infections. These results can be minimized by using a humidifier in a dry space, changing toiletries, and using lotions or moisturizers that replace lipid components.

Signs of dry skin

The skin loses a lot of water and can dry out and crack when dehydrated.

  • Dryness and noticeable fine lines
  • Itching Chapped or flaky skin
  • Rough touch Erythema

Dry skin can affect any part of the body and is most common on the hands, arms and legs. Staying hydrated not only improves skin shape and function but also helps other organs in the body function properly.

Dry skin not only damages the protective walls of the organs but also makes the skin susceptible to bacterial infections.

Causes of dry skin

Scleroderma or skin disease is a skin disease that affects millions of people around the world. Sometimes it can be due to a change in an individual’s environment, new skincare products, ageing, or disease. firewood.

Most people experience dry skin at some time of the year due to internal and external factors.


Diabetes, thyroid disease, kidney disease, contact dermatitis and atopic dermatitis can cause extremely dry skin. These disorders can alter the moisture content of both the skin and eyes. In other words, they can cause annoying dry eye syndrome as well. to dry skin.

The most common symptom of dry skin is itchiness, which has persistent and sometimes intolerable side effects, so it’s important that people with these conditions continue to use moisturizers to prevent dryness.

Extreme climate

During winter, when all internal and external air dries out (e.g. a heater), the blood actually leaves the epidermis and keeps the internal organs warm. Phosphorus can dry out the skin fairly quickly because of the heat of the air and the use of air conditioners absorb moisture from the skin.

People (and visitors) living in this type of climate should use as hot water as possible and take a short shower, after which we recommend applying a moisturizer to help protect your skin.

Excessive bathing

Bathing too often is one of the most common causes of dry skinMany soaps and shower gels on the market contain surfactants that break down oil and dirt on human skinWhile this ingredient helps the skin feel refreshed and clean, it dries out the skin and can cause short- and medium-term damage.

This is because chemicals do not differentiate between important lipid barriers of the body and remove them, allowing bacteria and viruses to enter.


The process of keratinization (natural exfoliation) and changes in lipids in the outer layer of the skin increase the likelihood of developing dryness with age. At the age of approximately 40, the body rapidly reduces the production of sebum, which is responsible to keep the skin soft and young. Over the years, the production of sebum continues to decrease, making the skin more easily dry.

Drought is a common disease, but it is closely related to ageing. However, there are plenty of tips out there to help moisturize and keep your skin healthy as it ages.


Tobacco contains toxins and chemicals that can start ageing.

People who smoke cigarettes often have dry facial skin and wrinkles around the mouth. Tobacco accelerates the breakdown of skin collagen and the tiny elastic fibres that make up the foundation of the dermis. For this reason, tobacco has been linked to premature ageing.

The relationship between skin pH and dry skin

The pH scale ranges from 1 to 14. pH7 is considered neutral, below it is considered acidic and above it is considered alkaline. The outer layer of human skin has a pH value of between 4-6, indicating that it is naturally acidic.

The skin is made up of sebum, amino acids and fatty acids. As the latter two names suggest, both ingredients are acidic, which helps the skin prevent bacterial colonies. Similarly, the lipid layer consists of fatty acids, cholesterol and ceramides. that work together as natural water repellants.

Most pathogenic bacteria are easily blocked by acids in human skin, however, this protective barrier cannot work effectively when the skin is dry or damaged. The inner layer of the skin has a pH value of approximately 7.4, which is ideal for the growth of bacterial colonies, therefore dryness is a risk factor for infectious dermatitis.

Regular use of moisturizers is an easy and effective way to protect your skin.

Moisturizing dry skin

If you experience dry or dry skin, the best thing to do is to shower with lukewarm water in a short period of time and apply plenty of moisturizers immediately after drying. This is the most effective time to absorb the emollient cream needed to strengthen the skin. protective skin barrier.

Remember, itching is a classic symptom of dry skin. Even at the first sign of very little itchiness, assume that your skin needs to rehydrate and apply your favourite moisturizer.
