Skin Ageing: The difference between the Intrinsic and Extrinsic Aging of Skin
Aging is a natural process, but not all signs of aging are inevitable. Understanding the difference between intrinsic and extrinsic aging is crucial for developing a skincare routine that effectively addresses the factors that contribute to premature aging. At MDRN Skincare, our approach is built around protecting and nourishing your skin, allowing you to maintain a youthful appearance despite environmental challenges.
Intrinsic Aging: The Body’s Natural Clock
Intrinsic aging, also known as chronological aging, is largely driven by genetics and the passage of time. It is the natural process that occurs as our bodies age, typically beginning in our mid-20s. This process is responsible for the gradual decline in skin elasticity, the thinning of the skin, and the development of fine lines and wrinkles.
Though intrinsic aging is unavoidable, it only accounts for about 10-20% of the visible signs of aging. The hallmark features of intrinsic aging include the slow breakdown of collagen, a reduced ability to retain moisture, and the overall thinning of the skin. These changes are subtle and occur at a relatively steady rate over time.
Extrinsic Aging: The Environmental Assault
In contrast, extrinsic aging refers to the changes in the skin that occur due to external factors such as sun exposure, pollution, smoking, and even diet. Research has shown that up to 90% of visible skin aging can be attributed to these extrinsic factors, particularly ultraviolet (UV) radiation (Lavker & Kaidbey, 1997). Chronic exposure to UV rays leads to a process known as photoaging, which causes deep wrinkles, pigmentation changes, and a leathery skin texture.
According to Yaar and Gilchrest (2007), UV exposure is the dominant factor in skin aging, especially in areas frequently exposed to the sun, such as the face and hands. Their study demonstrated that around 90% of skin aging in these areas is caused by cumulative sun damage. The effects of photoaging are far more pronounced than those caused by intrinsic aging, often leading to deep wrinkles, loss of elasticity, and dark spots.
Environmental pollution further exacerbates skin aging by increasing oxidative stress, which damages skin cells and accelerates the breakdown of collagen and elastin (Watson et al., 2014). The combination of UV radiation and pollution forms a one-two punch that speeds up the appearance of wrinkles and uneven skin tone.
Protecting Your Skin with MDRN
At MDRN, we understand the impact of these environmental factors and have designed our products to hydrate, protect, and enrich (HyPrEn) your skin. One of our most effective defenses against extrinsic aging is our SPF15 Hydrating Crème Moisturiser, which not only locks in moisture but also provides a protective barrier against harmful UV rays.
By incorporating our SPF15 Hydrating Crème into your daily routine, you can help prevent the premature aging effects of sun exposure while keeping your skin hydrated and nourished. Protecting your skin from extrinsic aging is essential, and a broad-spectrum SPF product is one of the most effective tools in your skincare arsenal.

The MDRN Difference
Our skincare system focuses on preserving the skin's natural balance while defending it against the damaging effects of external factors. We emphasize protecting your skin from over-cleansing and harsh surfactants, which can weaken the skin barrier, leaving it vulnerable to environmental stressors. Our HyPrEn Skincare System provides a holistic approach, targeting the root causes of both intrinsic and extrinsic aging.
Conclusion
While intrinsic aging is a natural part of life, the majority of visible skin aging is caused by external, preventable factors such as sun exposure and pollution. At MDRN, we are committed to helping you protect your skin from these external threats, with products designed to hydrate, protect, and nourish your skin. Our SPF15 Hydrating Crème Moisturiser is specifically formulated to help prevent premature aging while supporting your skin’s natural radiance.
