What is dry skin?
Dry skin, also known as psoriasis (dry itchy skin), is a condition in which the skin becomes dry and itchy. According to a study published in the journal Allergology International, this condition is caused by a disruption in the functioning of the stratum corneum (the outermost layer of the skin). This leads to a loss of fat and water in the outer layer of the skin, which reduces the skin’s protection and leads to a decrease in natural moisturizing factors (NMFs).
Thi condition can affect the beauty of the kin, ca can cause itching (dry itchy skin), and it can slow wound healing. It can also worsen other skin problems, such as inflammation and rashes.
Here are the causes of dry skin and itchy skin
1. Contact dermatitis
According to a study by Status Pearls, contact dermatitis, also known as eczema, is a skin condition that is caused by an allergy or reaction to something. A person who has this condition may experience swelling or discomfort when he or she comes in contact with some type of allergen or reactant.
This can lead to dryness and itching of the skin and can also cause blisters and redness, says dermatologist and cosmetologist Saumya.
Things that can aggravate contact dermatitis:
Nickel found in jewelry, coins and clothing fasteners.
Fragrances in soaps, perfumes, and lotions
Irritants—harsh chemicals, soaps, detergents, and solvents
Latex found in gloves, balloons, and other products
When the skin of a person with dermatitis comes into contact with these substances, their skin becomes inflamed and dry. This can cause intense itching, discomfort, and sometimes even cracking or peeling of the skin.
2.Atopic Eczema
Atopic eczema, also called atopic dermatitis, is a chronic skin condition that often causes dry and itchy skin. It causes patches of red and swollen skin, which may be dry or scaly, and sometimes ooze pus. There is no exact information about its cause, but the condition is thought to be caused by your genes and the environment around you. Both factors can combine to aggravate the condition.
People with atopic eczema have a greater sensitivity to irritants and allergens, which can trigger flare-ups and increase their skin’s dryness and itching. Constant itching further damages the skin’s protective barrier, leading to a constant cycle of dryness, itching, and inflammation.
3 Seborrheic dermatitis
Seborrheic dermatitis is a skin condition that causes patches of red, dry skin. It often affects areas with a high concentration of oil glands, such as the head, face, and chest. Although its exact cause is unknown, it is thought to be caused by an overgrowth of a type of yeast called Malassezia.
This yeast feeds on the natural oils produced by the skin, causing the skin to become inflamed and dry. Seborrheic dermatitis causes extreme dryness that can cause itching and discomfort. In severe cases, it can also affect the eyebrows, eyelashes, and behind the ears.
4. Psoriasis
Psoriasis is a chronic autoimmune condition that causes the skin to grow too quickly. This leads to the formation of thick, scaly patches that grow rapidly. These patches can be very itchy and painful, making you feel very embarrassed. The rapid growth of the skin in psoriasis weakens its natural defenses, leading to dryness and irritation.
Dryness can increase itching and make the condition even more uncomfortable. Additionally, people with psoriasis may be more susceptible to infection due to cracks in the skin, which can worsen the problem.
5. Environmental Factors
Dermatologist Dr. Neetu explains, “Environmental factors can be the main cause of dryness and itching in the skin. In cold and dry weather, the moisture from the skin is reduced, which increases dryness. Central heating and air conditioning also reduce the moisture inside, which makes the skin more dry. Staying in the sun for too long can also damage the skin’s protection, causing dryness and irritation.”
Apart from this, exposure to certain chemicals and irritants like hard soaps, detergents and solvents can also increase dryness and itching of the skin.
6. Lifestyle factors
Lifestyle factors can also contribute to dry and itchy skin. Dr. Neetu says, “Frequent bathing or showering, especially with hot water, can strip the skin of its natural oils, leading to dryness. Using hard soaps and detergents can further irritate the skin and strip it of essential moisture.
Certain medications, such as diuretics, corticosteroids, and retinoids, can also cause dry skin,” Additionally, not moisturizing regularly can also increase dryness and itching.
How to prevent dryness and itching on the skin (How to deal with dry itchy skin)
1. Moisturise regularly
This is especially important for dry skin. Immediately after showering, when your skin is still slightly damp, apply a gentle, unscented moisturizer. Choose moisturizers that contain ingredients like glycerin, urea, or ceramides, which help lock in moisture.
2. Pay attention to bath time and temperature
Long hot showers or baths can strip the natural oils from your skin. Try taking short, lukewarm showers. Use a gentle cleanser that won’t irritate your skin.
3. Protect your skin from environmental factors
Use a moisturizer with SPF when you go outside, especially in cold and dry weather or on sunny days. This will help protect your skin from harmful UV rays and help prevent dryness.
4. Avoid irritants and allergens
Identify substances that may irritate your skin and avoid them. This may include soaps, detergents, fragrances, or certain fabrics. A patch test can help you identify potential allergens.
5. Stay hydrated
Drinking enough water helps keep your skin hydrated from the inside. Try to drink at least 8 glasses of water daily to keep your skin hydrated.
6. Consider a humidifier
If you live in a dry climate, using a humidifier can increase the moisture in the air, which may be beneficial for your skin. You can also consult your dermatologist to find out if using a humidifier is good for your skin.
