Ageing is a journey that affects every part of our body, but it’s most visible in our skin. As we age, changes occur on a cellular and structural level that lead to wrinkles, sagging, dryness, and other visible signs of getting older. To support (dis)graceful ageing, it helps to understand what’s happening beneath the surface. Here, we’ll explore the mechanisms of skin ageing, the factors that accelerate it, and how lifestyle changes can slow its progress.
What Causes Skin to Age?
1. Collagen and Elastin Decline
Collagen is a protein that gives our skin structure and strength. By our mid-20s, we start producing about 1% less collagen per year, causing skin to lose its firmness and volume over time.
Elastin provides skin with its ability to stretch and snap back, like a rubber band. As we age, elastin fibres become less efficient, leading to loose, sagging skin. Combined with reduced collagen, this decline contributes to the formation of fine lines and deeper wrinkles.
2. Thinning of the Epidermis
The outermost layer of skin, the epidermis, becomes thinner and more fragile with age. This makes it easier to see veins, gives a translucent appearance, and makes the skin more prone to injury and irritation.
3. Fat Loss and Volume Changes
Beneath the skin lies a layer of fat that provides support and a youthful contour. Over time, we lose fat in certain areas, like the cheeks and around the eyes, which contributes to hollowing and sagging. Conversely, fat may accumulate in other areas, such as under the chin or around the jawline.
4. Slower Cell Turnover
Younger skin regenerates quickly, with skin cells turning over approximately every 28 days. As we age, this rate slows dramatically, leading to a build-up of dead skin cells on the surface. This results in a duller complexion and rough texture.
5. Reduced Oil Production
As hormone levels change, especially during menopause for women, sebaceous glands produce less oil. While this may reduce acne, it also means drier, less hydrated skin. Reduced moisture exacerbates the appearance of fine lines and creates a rougher feel.
6. Changes in Pigmentation
Over the years, cumulative sun exposure and hormonal changes can cause pigmentation issues, such as sunspots, age spots, and uneven skin tone. The skin’s ability to repair damage from UV radiation also diminishes, leading to further discoloration.
Factors That Accelerate the Aging Process
Sun Exposure (Photoaging)
The number one cause of premature skin aging is ultraviolet (UV) radiation from the sun. It breaks down collagen and impairs the skin’s ability to repair itself, leading to wrinkles, sagging, and dark spots. Up to 80% of visible facial ageing is attributed to sun exposure.
Lifestyle Choices
Smoking: Smoking narrows blood vessels and depletes oxygen and nutrients that are crucial for skin health. It also accelerates the breakdown of collagen and elastin.
Diet: A poor diet high in sugar and refined carbohydrates can lead to inflammation and damage to the skin’s structure. Conversely, antioxidant-rich foods (like fruits and vegetables) protect and support healthy skin aging.
Stress and Lack of Sleep: Chronic stress and insufficient sleep increase cortisol levels, which can break down collagen and thin the skin over time.
Genetics (Intrinsic Aging)
Our genetic makeup plays a role in how we age, including when and how wrinkles form, how quickly skin loses its firmness, and whether pigmentation issues occur. This is known as intrinsic ageing, and it can vary widely from person to person.
Environmental Toxins
Exposure to pollution, chemicals, and environmental toxins can accelerate skin aging by increasing oxidative stress. Free radicals generated from pollution attack healthy cells, degrading collagen and elastin.
Supporting Your Skin Through Ageing
While we can’t stop the clock, we can make lifestyle changes to slow the aging process and maintain skin health:
Sun Protection is Essential
Wearing sunscreen with broad-spectrum SPF 30 or higher daily is critical for protecting collagen and preventing further damage.
Hydration and Moisturization
Keeping skin hydrated helps maintain its barrier function and reduces the appearance of fine lines. Drink plenty of water and use moisturizers suited to your skin type.
Nutrition Matters
A balanced diet rich in antioxidants, omega-3 fatty acids, and vitamins (especially Vitamin C and E) can support collagen production and protect against oxidative stress.
Sleep and Stress Management
Adequate sleep allows the skin to repair itself overnight. Managing stress through practices like meditation or regular exercise can also reduce inflammation and cortisol levels.
Avoid Smoking and Limit Alcohol
Both smoking and excessive alcohol consumption can dehydrate the skin and accelerate collagen breakdown.
Remember to Keep a Positive Outlook!
Ageing is a natural and beautiful process, reflecting the experiences and wisdom gained over time. While it's fine to focus on maintaining your skin, it’s also important to focus on feeling confident at every stage of life. Education, preventative care, and smart lifestyle choices can help you glow from within, making the journey through ageing a rewarding one. Treatments such as anti-wrinkle injections, fillers, peels, and skin boosters can all play a part in this maintenance and also offer a sense of control over the situation. Do remember though, you're tweaking what you have, not creating something you don't. Don't expect too much at once and enjoy your DIY journey!
