Causes of Skin Problems and the Need for Rejuvenation

The aging process of the skin and the occurrence of various skin issues result from multiple internal and external factors that, over time, lead to structural and visual changes in the skin. These changes not only affect facial beauty but can also negatively impact an individual’s health and self-confidence. Skin rejuvenation through various methods, such as laser therapy, filler injections, microneedling, and non-invasive treatments, can help address these issues. Below, we examine the main causes of skin problems that necessitate rejuvenation:

Natural Aging Process

Aging is a natural biological process that gradually causes structural and functional changes in the skin over time. These changes include decreased production of collagen, elastin, and hyaluronic acid, which play crucial roles in skin firmness, elasticity, and hydration.

Decreased collagen and elastin production: Collagen is responsible for skin firmness and structure, while elastin ensures elasticity. With aging, the production of these proteins decreases, resulting in sagging, loose, and wrinkled skin.
Reduced hyaluronic acid: This substance hydrates the skin. Its reduction leads to dryness, volume loss, and the formation of fine lines.
Thinning skin: Different layers of the skin become thinner over time, losing their ability to repair themselves.

Sun Damage (Photoaging)

Continuous exposure to ultraviolet (UV) rays from the sun is one of the main causes of premature skin aging. This damage, known as photoaging, can have more profound effects than natural aging.

Collagen and elastin destruction: UV rays degrade these proteins, leading to wrinkles and skin sagging.
Dark spots (lentigo or melasma): Sunlight increases melanin production, resulting in dark spots and skin discoloration.
Dryness and roughness: Prolonged sun exposure reduces skin moisture, causing roughness and dryness.

Common Skin Problems Requiring Rejuvenation

Surface and deep wrinkles: Caused by reduced collagen and elastin.
Dark spots and skin discoloration: Due to sun damage or hormonal changes.
Skin sagging and loosening: Caused by tissue volume reduction and muscle atrophy.
Dryness and roughness: Due to reduced sebum and hyaluronic acid production.
Scars and marks: Resulting from acne or skin injuries.

Unhealthy Lifestyle

Various lifestyle factors can lead to premature aging and skin issues:

Smoking: Smoking reduces blood flow to the skin and damages collagen.
Unhealthy diet: Consuming processed foods, excessive sugar, and unhealthy fats can cause inflammation and premature skin aging.
Dehydration: Insufficient water intake causes dryness and reduced skin elasticity.

Genetic Factors

Genetics play an important role in determining skin type, collagen production levels, and the rate of aging. Some individuals experience wrinkles or sagging skin earlier due to their genetic makeup. Additionally, genetic disorders such as Ehlers-Danlos Syndrome can cause structural weaknesses in the skin.

Oxidative Stress and Free Radicals

Free radicals are unstable molecules that damage cells, proteins, and DNA. These molecules are naturally produced by the body’s metabolic processes but can also be increased by external factors such as air pollution, cigarette smoke, sunlight, and unhealthy diets.

Cellular damage: Free radicals destroy skin cells and reduce collagen production, leading to wrinkles and skin sagging.

Hormonal Changes

Hormonal changes, particularly during menopause, pregnancy, or severe stress, can significantly affect skin health. Decreased hormones like estrogen and testosterone thin the skin, reduce collagen and elastin production, and decrease skin moisture.

Menopause: During this period, a sharp decline in estrogen causes skin volume loss and wrinkle formation.
Hormonal disorders such as Polycystic Ovary Syndrome (PCOS): This condition can cause skin problems like acne and pigmentation changes.

Severe Weight Loss

Sudden and significant weight loss can lead to the loss of subcutaneous fat, which plays an essential role in maintaining skin structure and firmness. This condition causes sagging skin, particularly in areas such as the face, neck, and arms.

Chronic Stress

Continuous stress increases the production of the hormone cortisol, which can reduce collagen production and damage the skin structure. Stress also exacerbates skin conditions such as eczema, psoriasis, and acne.

Environmental Factors and Air Pollution

Air pollution contains fine particles and harmful chemicals that penetrate the skin, causing inflammation, oxidative stress, and collagen degradation. These factors contribute to wrinkles, dark spots, and skin sagging.

Improper Skin Care

Failing to use appropriate skincare products, such as sunscreens, moisturizers, and antioxidants, can accelerate skin aging. Overwashing or using unsuitable products can also damage the skin.

Skin problems requiring rejuvenation arise from various causes such as natural aging, environmental damage, hormonal changes, and unhealthy lifestyles. These factors result in structural changes in the skin, leading to wrinkles, sagging, dark spots, and loss of skin radiance. Skin rejuvenation through various methods can address these issues and restore a younger, more vibrant appearance. Proper care, prevention of environmental damage, and appropriate treatments are key to maintaining healthy and beautiful skin.

Treatment with Leading Technologies Worldwide

Cold and Warm Plasma, Carboxytherapy, and Nd:YAG Laser Technologies
Each of these technologies offers unique features and mechanisms, providing diverse options for skin rejuvenation. The choice of an appropriate technology depends on the skin type and individual needs of the patient, determined by dermatology specialists to achieve the best possible results.

Nd:YAG Laser (1064 nm)

The Nd:YAG laser, operating at a 1064-nanometer wavelength, is one of the advanced technologies for skin rejuvenation. It penetrates deeper into the skin and specifically targets underlying tissues. This laser stimulates collagen production and improves skin structure, helping to reduce wrinkles and pigmentation. The 1064-nanometer wavelength is also suitable for all skin types and, due to reduced melanin absorption, is safer for darker skin tones.

Cold and Warm Plasma

Plasma, a state of matter where gas is converted into charged ions, produces very high energy. In aesthetic medicine, plasma is used in two forms, cold and warm, for skin rejuvenation:

Warm Plasma: This type of plasma, due to its high temperature, is utilized for treating deeper wrinkles and skin laxity. Warm plasma creates controlled wounds on the skin surface, stimulating tissue regeneration and promoting new collagen production.
Cold Plasma: Cold plasma operates at lower temperatures and uses less energy, making it effective for improving skin texture without damaging deeper layers. This type of plasma is beneficial for issues like acne, skin spots, and surface tightening with fewer side effects.

Carboxytherapy

Carboxytherapy, or CO₂ gas therapy, is a natural and effective method for skin rejuvenation. This technique involves injecting carbon dioxide into skin layers, stimulating blood flow and increasing oxygen delivery to tissues. The increased oxygen promotes new collagen production and enhances skin texture, leading to reduced wrinkles, skin laxity, and improved skin tone. Carboxytherapy is highly regarded as a non-invasive treatment requiring no downtime.

Review of Modern Technologies for Skin Rejuvenation

Skin rejuvenation using modern technologies is an effective method for improving the appearance and health of the skin. Each of these technologies has unique mechanisms and is selected based on the specific needs of the patient. Below is a detailed review of each technology, its positive effects, advantages, and related scientific studies.
