To keep your skin youthful, collagen (also known as collagen protein) is essential. Collagen in the skin is found in the dermis layer and is produced by fibroblasts. It helps lock in moisture and maintain elasticity. However, as we age and our metabolism slows down, the efficiency of collagen production decreases. After the age of 40, we lose about 1% of collagen each year, leading to rough, sagging skin, increased wrinkles, and enlarged pores.

Additionally, frequent exposure to UV light, air pollution, smoking, drinking, or an unbalanced diet can accelerate the breakdown of collagen in the body.

If you're still in your teens or early twenties, it's even more important to pay attention to collagen levels, as everyone has a limited quota. A 25-year-old who stays up late, smokes, drinks, and doesn't take care of herself can look worse than a well-maintained 35-year-old woman. Here are some tips to help maintain collagen levels:

1. Diet: To maintain collagen levels through diet, it's recommended to eat 5 to 8 ounces of meat daily. However, consuming too much animal protein can increase the burden on the kidneys or lead to osteoporosis. Foods like pig skin, pig feet, and chicken feet are high in collagen but also high in fat, so eating too much can lead to weight gain.
2. Vitamin C: Adequate vitamin C helps the body produce collagen and promotes cell growth. During the pandemic, it can also boost immunity.
3. Reduce Sugar Intake: Sugar intake should be controlled to less than 5 teaspoons per day. Excessive sugar can damage collagen structure and accelerate its loss, leading to faster skin aging.
4. Sun Protection: UV rays from the sun and blue light from phones and computers can accelerate collagen loss. Choose sunscreens that offer blue light protection for more comprehensive coverage.
5. Skincare Treatments: Choose appropriate beauty treatments and maintain regular care to delay aging.

These tips are common advice, but it's important to remember that everyone's skin is different. For a thorough solution to blackheads and acne, it's best to consult a dermatologist rather than attempting to remove blackheads yourself.
