Dry skin is a common condition that can be uncomfortable, irritating, and even painful. If you’ve ever experienced itchy, flaky, or rough patches on your skin, you know how frustrating it can be. But what causes dry skin, and how can you prevent it? In this blog post, we’ll explore the key factors behind dry skin and some practical tips for keeping your skin healthy and moisturized.

First, let’s take a closer look at what dry skin actually is. Dry skin occurs when your skin loses its natural moisture and becomes dehydrated. This can happen for a variety of reasons, including:

Weather: Cold, dry air can suck the moisture out of your skin, leaving it dry and flaky. Exposure to wind and sun can also contribute to dryness.

Hot showers and baths: Although it may feel relaxing to take a long, hot shower or bath, it can actually dry out your skin. The hot water can strip your skin of its natural oils, leaving it dehydrated.

Harsh soaps and detergents: Many soaps and detergents contain chemicals that can be harsh on your skin. Using these products can strip your skin of its natural oils, leading to dryness.

Medical conditions: Certain medical conditions, such as eczema, psoriasis, and thyroid disorders, can cause dry skin.

Age: As we age, our skin naturally becomes thinner and loses some of its natural oils. This can lead to dryness and itchiness.

So, how can you prevent dry skin? Here are a few tips to keep in mind:

Moisturize: Using a good moisturizer can help keep your skin hydrated and prevent dryness. Look for a moisturizer that’s formulated for your skin type and use it regularly, especially after showering or washing your hands.

Avoid hot water: Try to avoid taking hot showers or baths, as this can strip your skin of its natural oils. Instead, opt for warm water and limit your shower or bath time to 10-15 minutes.

Choose gentle products: Look for gentle, fragrance-free soaps and detergents that won’t dry out your skin. If you have a medical condition that’s causing your dry skin, talk to your doctor about treatment options.

Stay hydrated: Drinking plenty of water can help keep your skin hydrated from the inside out. Aim for at least eight glasses of water a day.

Humidify: Using a humidifier in your home can help add moisture to the air, which can in turn help prevent dry skin.

By following these tips, you can help prevent dry skin and keep your skin looking and feeling healthy. Remember, if you have persistent dryness or itching, it’s always a good idea to talk to your doctor or a dermatologist for advice.

Skin cancers are cancers that arise from the skin. They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body.[10] There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma.[1] The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC).[5][11] Basal-cell cancer grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death.[5] It often appears as a painless raised area of skin that may be shiny with small blood vessels running over it or may present as a raised area with an ulcer.[1] Squamous-cell skin cancer is more likely to spread.[5] It usually presents as a hard lump with a scaly top but may also form an ulcer.[2] Melanomas are the most aggressive. Signs include a mole that has changed in size, shape, color, has irregular edges, has more than one color, is itchy or bleeds.[3]

More than 90% of cases are caused by exposure to ultraviolet radiation from the Sun.[4] This exposure increases the risk of all three main types of skin cancer.[4] Exposure has increased, partly due to a thinner ozone layer.[5][12] Tanning beds are another common source of ultraviolet radiation.[4] For melanomas and basal-cell cancers, exposure during childhood is particularly harmful.[6] For squamous-cell skin cancers, total exposure, irrespective of when it occurs, is more important.[4] Between 20% and 30% of melanomas develop from moles.[6] People with lighter skin are at higher risk[1][13] as are those with poor immune function such as from medications or HIV/AIDS.[5][14] Diagnosis is by biopsy.[3]

Vitamin D Deficiency | Absorption & Metabolism, Purpose of Vitamin D, Causes of Deficiency

Vitamin D Deficiency is a very common worldwide condition, involving inadequate levels of vitamin D. Vitamin D refers to a number of fat soluble vitamins that are garnered from dietary sources or through endogenous synthesis. Vitamin D is absorbed in the gastrointestinal system and is also synthesized in the skin from cholesterol precursors. In this lesson, we discuss these topics in more detail, including why we need vitamin D (ex. calcium homeostasis), and a variety of causes of vitamin D deficiency.

This lesson is part 1 in a series on Vitamin D deficiency. In the next lesson, we discuss the signs and symptoms of vitamin D deficiency, along with methods of diagnosing and ways of treating Vitamin D deficiency.
