Is my skin lacking moisture? Let's try the back of the hand test.

One of the major factors that cause skin aging is 'dryness.' Learn about ways to keep the skin moisturized.

 

◇Increase water intake to improve skin elasticity

Drinking plenty of water can improve skin elasticity. The skin is composed of about 70% moisture. When the skin lacks moisture, collagen and elastic fibers are not produced well. As a result, skin loses elasticity and wrinkles form. Consuming water replenishes moisture and promotes smooth blood circulation, making the skin clearer. Additionally, water lowers skin temperature. The higher the skin temperature, the more sebum is secreted. Drinking water at this time can lower skin temperature and reduce sebum production.

 

◇Pinch the back of the hand to check fluid intake

If you usually do not drink enough fluids, drink more water to improve your skin condition. Severe dehydration reduces blood circulation, which impairs the hyaluronic acid function that maintains moisture and promotes elasticity in the skin, making the skin look dull and more wrinkled.

 

A simple method to check if you are drinking enough fluids is the "back of the hand pinching test." It involves pinching the skin on the back of the hand with your thumb and index finger for 5 seconds, then timing how long it takes to return to normal. If the skin on the back of the hand does not return to its original state within 2 seconds, it may indicate dehydration.

However, the fingertip pinch test is not effective for people with certain conditions such as the elderly or autonomic nervous system disorders.

In addition, symptoms such as ▲headache ▲dry mouth ▲severe thirst ▲dark-colored urine are also common signs of dehydration.

 

Apply moisturizer and avoid processed foods

To keep the skin moist, external moisturizing is also important. Properly use moisturizers that attract and retain moisture, and ingredients that form a barrier to trap skin moisture. Moisturizer ingredients include hyaluronic acid, while ingredients that trap moisture include substances like Vaseline or lanolin. After washing, apply moisturizer and skin barrier-forming products in order while the skin still has some water remaining.

 

 

Avoiding sun exposure is also a method. Ultraviolet rays damage skin DNA, causing wrinkles and creating freckles and dark spots. Prolonged and continuous exposure to UV rays increases the risk of skin cancers such as melanoma. To prevent premature aging, it is advisable to apply sunscreen carefully and avoid sun exposure during the peak UV hours from 10 a.m. to 4 p.m.

 

Avoiding processed foods with added sugar also helps with skin hydration. Sodium depletes a large amount of moisture from collagen in the skin, making the skin dry. When the skin is dry, its elasticity decreases, leading to the formation of fine lines. Additionally, eating sugary foods raises blood sugar levels, causing active oxygen and advanced glycation end products to accumulate in the body, which accelerates skin aging. Advanced glycation end products are simply called 'sugar toxins.' They are not easily broken down in the body, and about 10% of them accumulate in the blood or tissues.
