Usually, people look at their face to roughly estimate their skin age based on wrinkles and elasticity, but it is difficult to determine the exact skin age. In such cases, pinching the back of the hand can be a helpful method.

The longer the skin recovery time, the older you look

According to the aging measurement standards of the Korea Institute of Biological Age Medicine, you can determine skin age just by pinching the back of the hand. Gently bend the back of the hand, then use the thumb and index finger to pull the skin on the back of the hand for 5 seconds, and then measure the time it takes to return to its original state. The longer the recovery time, the lower the skin elasticity. If the recovery time is 1 to 2 seconds, it indicates skin age in the 20s to 30s; 2 to 5 seconds corresponds to the 40s to 50s; and over 10 seconds suggests a skin age in the 60s.

◇Lifestyle habits to keep your skin age young

To make aging skin look younger, you must follow the following guidelines.

▷Avoid salty and sweet foods = Eating salty and sweet foods promotes skin aging. Salt draws a large amount of moisture from collagen in the skin, making the skin dry. Dry skin loses elasticity and is prone to fine lines. Frequently consuming sugary foods is also harmful to the skin. When sugar intake raises blood sugar levels, reactive oxygen species and advanced glycation end products accumulate in the body, which accelerates skin aging.

▷Applying sunscreen = For youthful skin, you should apply sunscreen daily regardless of the season. When exposed to ultraviolet rays, the skin thickens and becomes dry to defend itself. Excess melanin pigment is produced, leading to blemishes and dark spots. Additionally, the skin ages faster, making wrinkles more likely to form.

▷Maintaining a consistent bedtime = To achieve youthful skin, you should sleep between 10 PM and 2 AM. This is because this period is when skin regeneration is most active. If you stay awake during this time or do not get deep sleep, skin regeneration may not proceed smoothly, making it easier for symptoms like wrinkles or sagging skin to develop.

▷Preventing moisture loss = During cold and dry weather like now, it is important to carefully apply basic skincare products. This is because cold and dry conditions can easily reduce skin elasticity. However, it is best to apply them before the face is completely dry after washing. Otherwise, the moisture will evaporate, causing both water and oil to be lost.
