Why Does Skin Aging Occur?
Hello, I am Dr. Sang-ju Lee, a dermatologist at Yonsei Star Dermatology Sinchon. Today, we will delve into how to reverse the age of the skin, specifically Pre-rejuvenation.
Skin aging is a natural phenomenon that simply occurs over time. However, its causes can be broadly divided into two categories:
- Extrinsic Aging (External Stimuli): The skin's biggest role is to defend our body from external factors.
- Ultraviolet (UV) Rays: The most representative cause of skin aging, it also increases the risk of skin cancer. The use of sunscreen, parasols, and sunglasses is important.
- Other Light Rays: Recently, it has been known that prolonged exposure to light rays other than UV can also be detrimental to the skin.
- Fine Dust and Pollutants: These can irritate and inflame the skin upon contact, potentially accelerating aging.
- Chemicals and Toxins: Contact with these on the skin can cause aging.
- Intrinsic Aging (Internal Factors): This is the phenomenon of our body naturally aging over time.
- Genetic Factors: There are cases where aging progresses faster or slower due to genetic predisposition.
- Hormonal Changes: Especially in women, skin aging can accelerate during menopause.
- Systemic Diseases: Not only diabetes and high blood pressure, but also certain skin conditions can speed up the rate of skin aging.
Is My Skin Aging Extrinsic or Intrinsic?
If you're curious whether the main cause of your skin aging is external stimuli or internal factors, you can easily find out by comparing your arms.
The outer part of the arm is exposed to a lot of sunlight, while the inner part is exposed less. When young, the elasticity, shape, and color of the skin on the inner and outer parts of the arm are almost the same. However, as one ages, the outer skin tends to develop more blemishes, lose elasticity, and become drier. This is because the outer part shows the sum of extrinsic and intrinsic aging, while the inner part is mainly affected by intrinsic aging. The skin on the inner buttocks, which is never exposed to sunlight, is a part where almost only intrinsic aging progresses.
If the aging on the outer part of your arm is severe, it could be a sign that you need to pay more attention to UV protection.
Main Symptoms of Skin Aging
Aging is not a disease or an accident, but a phenomenon where the structure and function of living organisms decline over time. Skin aging, unlike the aging of other organs, can be directly observed. Generally, skin aging brings about four types of changes:
- Skin Color Change: Not only do blemishes and age spots appear, but the skin can also turn yellowish or dull, unlike the clear and transparent skin of youth. This is due to changes in collagen and elastin fibers within the skin.
- Wrinkle Formation: Starting with fine lines around the eyes and on the forehead, these can gradually become deeper and thicker wrinkles through the 20s and 30s.
- Loss of Elasticity: When touching the skin, you may feel a decrease in resilience and firmness.
- Skin Sagging and Hollowing: If the loss of elasticity becomes severe, the skin may sag, such as in the nasolabial fold area, or certain areas may appear hollow.
Various Procedures for Skin Aging
In the early 2000s, there were reports that skin treatment using IPL devices was effective in improving symptoms of skin aging. This was a case where, beyond treating specific lesions, treating the entire face resulted in an overall rejuvenating effect on the skin, which subsequently led to the development of various dermatological procedures.
1. Energy-Based Procedures
- Laser: Creates microscopic injuries or stimulates the skin to induce collagen production. Recently, Fractional Laser, which stimulates only a part of the skin without ablating the entire surface, has gained popularity. This has the advantage of faster wound healing and reduced side effects.
- Radiofrequency (RF): Devices such as Thermage FLX and Oligio deliver RF energy to the inner part of the skin, generating heat. This heat stimulates fibroblasts, which produce collagen, helping to improve skin elasticity. It has the advantage of not causing damage to the skin surface, thus having minimal impact on daily life. RF microneedling devices like Potenza and Genius deliver RF energy deep into the skin through micro-needles to induce rejuvenation.
- Ultrasound: Unlike diagnostic ultrasound, HIFU ultrasound such as Ulthera concentrates ultrasound energy at a single point to generate heat. This heat stimulates fibroblasts within the skin, helping to improve the skin. It has the advantage of being able to deliver energy deep into the skin.
- Broadband Light (BBL): Broadband Light (BBL) is an upgraded device from IPL, using various wavelengths of light to simultaneously treat multiple aging symptoms such as pigmentation, redness, and skin texture improvement. In particular, BBL has been reported to prevent the progression of skin aging and increase the expression of youthful genes, restoring the skin at a molecular biological level, and is gaining attention overseas. It is known as a procedure with less pain and minimal strain on the skin.
2. Injection and Lifting Procedures
- Botulinum Toxin: Injected into the muscle layer beneath the skin to suppress the formation of expression wrinkles.
- Filler: Hyaluronic acid fillers are used relatively safely and help improve wrinkles by adding volume.
- Skin Boosters: Ingredients that help collagen production are injected into the skin to make it healthier.
- Thread Lift: If surgery is a burden, this procedure uses medical threads to pull the skin, improving sagging. Various types of threads may be used.
Each of these procedures has its own advantages and disadvantages, and the appropriate procedure may vary depending on an individual's skin condition and degree of aging. It is important to choose the right procedure for you through sufficient consultation with medical professionals.
Daily Practices for Skin Aging Prevention
In addition to medical procedures, consistent daily care and habit improvement are very important in preventing and delaying skin aging.
- UV Protection: Meticulously applying sunscreen is most important. Special attention should be paid in places with strong UV exposure, such as ski resorts or beaches. Sunglasses, hats, and parasols also help protect the skin and eyes from UV rays.
- Topical Medications: Retinoid-containing medications (e.g., Stieva) have been reported to be effective in improving symptoms of skin aging. However, as they can irritate Korean skin, it is important to use them consistently at an appropriate concentration and method under expert guidance. Retinol-containing cosmetics can also be helpful, but their effectiveness may be less than that of medications.
- Smoking Cessation: The heat and harmful substances generated during smoking cause wrinkles around the mouth and accelerate skin aging. This can be as harmful to the skin as UV rays.
- Stress Management: Stress is the root of all diseases and has a negative impact on skin health.
- Regular Exercise: Can help blood circulation and contribute to skin cell activation.
- Healthy Diet: It is important to consume sufficient nutrients necessary for skin health.
- Overall Health Management: Our entire body must be healthy to slow down the aging of all organs, including the skin.
Conclusion: Integrated Management for Healthy and Youthful Skin
Skin aging is an unavoidable natural phenomenon, but its speed can be slowed down and improved with appropriate management and effort. Already aged skin can be improved and the progression of aging can be prevented with non-surgical procedures such as Ulthera Prime, Thermage FLX, or broadband light therapy like BBL.
Along with this, consistently practicing healthy lifestyle habits such as regular exercise, a healthy diet, stress reduction, smoking cessation, and most importantly, using sunscreen, is essential for maintaining young and healthy skin. We hope you cultivate vibrant skin through integrated management tailored to your skin condition.
