Skin Type Series ①: How to Identify and Understand Dry Skin

 

Introduction: Let's Start by Answering, "What's My Skin Type?"

In our previous articles, we learned about the fundamental "structure" and "functions" of the skin. Starting today, we're diving into a more personal topic: "skin types."

The first step to effective skincare is correctly identifying your own skin type. 

When you understand the current condition of your skin, you can confidently choose the products that you truly need from the countless options available.

In this first article of the series, we will focus on a common concern for many: "dry skin."

Whether you've always suspected you have dry skin or you simply want to re-evaluate your skin type, let's explore it together.

Do You Have Dry Skin? A Quick Self-Check

"Dry skin" is a condition where the skin is lacking in both moisture (water) and sebum (oil). Think about your own skin as you go through the checklist below.  

• □ Does your skin feel tight immediately after washing?

• □ Does your skin often feel rough or look flaky and scaly?

• □ Are fine lines more noticeable, especially around your eyes and mouth?

• □ Does your makeup sometimes look cakey or fail to apply smoothly?

• □ Is your skin texture fine, but lacking a healthy glow or radiance?

• □ Does your skin sometimes become itchy or irritated, especially during seasonal changes or in certain environments?

• □ Do you notice your skin feels particularly dry in the winter or in air-conditioned rooms? 

If you checked three or more of these boxes, there's a high probability that you have dry skin.

What are the Main Characteristics of Dry Skin?

If the self-check made you think you might have dry skin, here are its main characteristics in more detail.

• Look and Feel 

  The surface of the skin feels and looks rough, flaky, or scaly. It lacks a natural luster and can appear dull. In more severe cases, the skin may crack, peel, or even bleed.

• Pores 

  Because sebum production is low, pores are typically small and not very visible. This is a key difference between dry and oily skin types.

• Common Concerns 

  The skin's protective barrier is compromised, making it highly sensitive to external aggressors like UV rays and pollution. This can lead to itchiness, redness, and irritation. Dry skin is also more prone to developing fine lines and cracks, which can deepen over time if not properly cared for.

What Causes Skin to Become Dry?

Dry skin isn't caused by a single factor. It's often a complex interplay between "internal factors" like your lifestyle and "external factors" like your environment.

■ Internal Factors

• Aging: As we get older, our skin naturally produces less sebum (oil) and other substances like ceramides that help it retain water. Nearly everyone has dry skin by the age of 60.

• Lifestyle: Lack of sleep and stress can disrupt the skin's turnover cycle, impairing its ability to maintain a healthy barrier.

• Medical History: Conditions like eczema (atopic dermatitis) or psoriasis make you more prone to dry skin.

• Nutrition: A deficiency in certain vitamins, such as A and D, or minerals like iron and zinc, can contribute to excessively dry skin.

■ External Factors

• Environment: Cold, windy weather and low-humidity climates can strip moisture from the skin. Indoor heating and air conditioning also reduce humidity, leading to dryness.

• Bathing Habits: Taking long, hot showers or baths, and using harsh soaps or detergents, can remove your skin's natural protective oils.

• UV Exposure: Sun damage compromises the skin's outermost layer, reducing its ability to hold onto moisture. 

Conclusion: Know Your Skin to Break the Cycle of Dryness

In this article, we've covered how to identify dry skin, along with its key characteristics and causes.

• Dry skin lacks both water and oil, resulting in a weakened protective barrier.

• Key signs include tightness after washing, roughness, flaking, and visible fine lines.

• It is caused by a combination of internal factors (like aging and lifestyle) and external factors (like weather and UV exposure).

Ignoring dry skin can lead to a vicious cycle of irritation and further damage. 

The first real step toward achieving beautiful, comfortable skin is to correctly identify your skin type and begin addressing the habits that may be contributing to dryness.
