保持肌膚健康年輕的方法

If you want your skin to look young and radiant, you need to understand the aging of the skin. Aging is mainly due to two reasons, which two reasons? One is internal aging and the other is photo aging. Simply put, too many free radicals in the body or too much stimulation from the sun will cause the skin to age and become dull, so how can we solve this?

Understanding Skin Aging

The human body begins to age after the age of 25. When we are young, our faces are full of fat, but after the age of 30, this fat shrinks, resulting in skin sagging, such as eye bags or tear troughs. Aging is related to an excess of free radicals in the body. If too many free radicals are produced, it will make people age more easily because free radicals damage cells and cause wrinkles to appear on the skin.

So how do we fight free radicals and oxidation?
Then you should eat more antioxidant-rich foods, such as colorful fruits and vegetables, to replenish anthocyanins and fight oxidation. Antioxidants work by combating free radicals generated in the body.

What exactly are free radicals?
When cells need to produce energy, they rely on mitochondria, intracellular structures, to generate energy. However, when mitochondria use glucose to produce energy, a byproduct called free radicals is produced. Free radicals are harmful waste products that can damage cells and even disrupt cellular genes. Therefore, it is necessary to eliminate these free radicals. Antioxidant enzymes in the body can convert free radicals into water and hydrogen and eliminate them. Studies have shown that phytochemicals and anthocyanins in many fruits and vegetables also have the function of eliminating these free radicals.

Why can sunscreen delay skin aging?
Light is an electromagnetic wave, and the shorter the wavelength, the greater the damage to the skin. Therefore, for the skin, the main factor affecting skin texture is short-wave ultraviolet radiation. Ultraviolet radiation can be divided into UVA and UVB, with UVB being more harmful to the skin, causing melanin production. When buying sunscreen, pay attention to the SPF index. This is the sun protection factor; the higher the SPF number, the better the sun protection effect. For example, SPF 50 means it can extend the sun protection time by up to 50 times. In addition to SPF, you should also indicate the UVA and UVB values to ensure the sunscreen lotion is suitable.

[Preventing and Improving Aging]

Sunscreen

Skin care should begin in youth, and this includes sun protection. The sun's rays we receive from a young age can influence the appearance of our skin's aging process. Proper sun protection from a young age can prevent sun damage, which makes wrinkles more noticeable. Therefore, sun protection is not only about preventing tanning but also about fighting skin aging. Besides carefully choosing a sunscreen suitable for your skin type, it's important to apply it evenly and suffice. If you're going to be outdoors for an extended period, reapply sunscreen after four hours to maintain its effectiveness.

Moisturizing

After entering your twenties, it's crucial to focus on moisturizing, especially for those with dry skin. Moisturizing involves hydration and locking in moisture. Generally, you should hydrate first, such as with a serum or toner, and then lock in the moisture, such as with a lotion, cream, or oil-based skincare product. Women in their late twenties and early thirties often rely on technology, such as skincare products or internal regulators. Diet also affects aging; eating plenty of fruits and vegetables and exercising regularly ensures sufficient oxygen in cells and helps prevent the buildup of free radicals.
