Causes of skin aging

As we age, our skin undergoes various changes that can lead to the appearance of wrinkles, fine lines, and other signs of aging. Understanding the causes of skin aging is essential for developing effective strategies to maintain a youthful complexion. Many clinics offer advanced treatments like Botox, PRP, Profhilo, dermal fillers, and polynucleotides to combat these changes. This article explores the primary causes of skin aging and how you can address them with the latest aesthetic treatments.

Intrinsic Aging

Intrinsic aging, also known as chronological aging, is the natural aging process that occurs over time. It is influenced by genetic factors and is an inevitable part of getting older. Intrinsic aging leads to a gradual decline in the production of collagen and elastin, proteins that are crucial for maintaining the skin’s firmness and elasticity. As a result, the skin becomes thinner, drier, and less resilient. Fine lines and wrinkles begin to appear, and the skin may start to sag.

Extrinsic Aging

Extrinsic aging is caused by external factors that accelerate the aging process. Unlike intrinsic aging, extrinsic aging can often be controlled or mitigated through lifestyle choices and protective measures. The most significant contributors to extrinsic aging include:

Sun Exposure

Ultraviolet (UV) radiation from the sun is the leading cause of extrinsic aging, often referred to as photoaging. Prolonged sun exposure damages the skin’s collagen and elastin fibers, leading to wrinkles, sagging, and pigmentation changes. UV rays also increase the production of free radicals, which further contribute to skin aging and the development of age spots and uneven skin tone.


Living in urban areas, such as South London, exposes your skin to higher levels of environmental pollutants. These pollutants can penetrate the skin and cause oxidative stress, leading to inflammation, collagen breakdown, and premature aging. Particulate matter, smoke, and other pollutants can exacerbate the signs of aging, making the skin appear dull and tired.

Lifestyle Factors

Certain lifestyle choices can significantly impact the rate at which your skin ages. Smoking, for instance, reduces blood flow to the skin, depriving it of essential nutrients and oxygen. This leads to the breakdown of collagen and elastin, causing wrinkles and sagging. A poor diet lacking in antioxidants, vitamins, and minerals can also accelerate skin aging. Additionally, chronic stress and lack of sleep can contribute to the appearance of fine lines, dark circles, and a loss of skin vitality.

Repetitive Facial Expressions

Repetitive facial movements, such as frowning, squinting, or smiling, can lead to the formation of dynamic wrinkles. Over time, these expressions cause the underlying muscles to contract and create permanent lines on the skin. For example, frowning can lead to the development of forehead lines and glabellar lines (the vertical lines between the eyebrows), while smiling can contribute to crow’s feet around the eyes.

Genetic Factors

Genetics play a significant role in how our skin ages. Your genetic makeup determines your skin type, tone, and overall structure, influencing how quickly signs of aging appear. Some people may have a genetic predisposition to develop wrinkles, pigmentation changes, or other age-related skin concerns earlier than others. While you cannot change your genetics, understanding your predispositions can help you take proactive steps to maintain healthy skin.

Hormonal Changes

Hormonal fluctuations, particularly during menopause, can have a profound impact on the skin. The decline in estrogen levels during menopause leads to a decrease in collagen production, resulting in thinner, less elastic skin. This hormonal change can also cause dryness, sensitivity, and a reduction in skin density, making wrinkles and sagging more pronounced.

Advanced Treatments for Skin Aging

A variety of advanced aesthetic treatments are available to address the causes of skin aging and restore a youthful appearance. Here are some of the most effective options:


Botox injections are highly effective for reducing dynamic wrinkles caused by repetitive facial expressions. By temporarily relaxing the underlying muscles, Botox smooths out lines on the forehead, around the eyes, and between the eyebrows. This treatment provides a more youthful and refreshed appearance without altering your natural expressions.

PRP (Platelet-Rich Plasma) Therapy

PRP therapy uses your body’s own platelets to stimulate collagen production and promote skin regeneration. This treatment is ideal for improving skin texture, reducing fine lines, and enhancing overall radiance. PRP therapy harnesses the natural healing properties of your blood, making it a safe and effective option for rejuvenating the skin.


Profhilo is a unique hyaluronic acid-based treatment designed to hydrate and tighten the skin. Unlike traditional dermal fillers, Profhilo spreads evenly across the skin, providing a subtle lift and improving skin tone and texture. This treatment stimulates collagen and elastin production, resulting in smoother, firmer skin.

Dermal Fillers

Dermal fillers are versatile treatments that can restore volume, smooth out deep wrinkles, and enhance facial contours. Hyaluronic acid-based fillers are commonly used to plump the cheeks, lips, and under-eye areas, providing a natural-looking enhancement. Dermal fillers help to combat the loss of volume and structure that occurs with aging.


Polynucleotides are an innovative treatment that stimulates cell regeneration and repairs damaged tissue. They improve skin elasticity, reduce the appearance of wrinkles, and promote long-term skin health. Polynucleotides are particularly effective for addressing signs of aging at a cellular level, making them a valuable addition to your anti-aging regimen.
