Skin Ageing

Understanding causes and risk factors for skin ageing is critical to effectively prevent and treat ageing skin.

Skin ageing is a natural process that everyone goes through. Over time the skin makes less collagen and elastin, so it becomes thinner, drier and less firm. This shows up as fine lines, wrinkles, loss of volume, large pores and uneven tone. Some ageing is down to your genes, but a great deal is driven by the sun and lifestyle. The good news is that the parts driven by external factors are largely within your control. In this guide we explain what skin ageing is, what causes it and how it shows on the skin. We also cover how how to slow down or prevent it and the best anti-ageing treatments.

City Skin Clinic is an online skincare clinic. We provide personalised medical ati-ageing skincare and do not offer in-clinic procedures such as chemical peels, laser treatment or energy-based devices. However, we have explained all the options below because we believe the public deserve clear, evidence-led information without commercial bias.

What is Skin Ageing?

Skin ageing is the gradual change in the skin’s structure and appearance over time. It is part of how the whole body ages, and the skin simply shows it more visibly. As we get older, the skin produces less collagen and elastin, the proteins that keep it firm and springy. The skin also renews itself more slowly and holds onto less moisture. As a result, it becomes thinner, drier and more prone to lines and sagging. Ageing skin is not a problem to be fixed, but its visible signs can be slowed and improved.

What Causes Skin Ageing?

There are two different causes of skin ageing causes. One is built in and the other is down to the world around us. The two causes of skin ageing are:

  • Intrinsic (internal) ageing: This is the ageing programmed in your genes. It starts earlier than most people think. From the mid-20s, collagen and elastin slowly decline, so fine lines and slackness build up over the years. Women lose collagen especially quickly after the menopause, which thins the skin and reduces firmness.
  • Extrinsic (external) ageing: This is ageing driven by the environment and lifestyle, and much of it is preventable. The sun is by far the biggest external cause, a process known as photoageing. Smoking, pollution, poor sleep and a poor diet add to it by creating oxidative stress in the skin.

What are the Signs of Skin Ageing?

Skin ageing manifests in several different signs, and most people get a mix of them. The earliest indicators are usually fine lines, followed by deeper wrinkles and structural changes over time. The main signs of skin ageing are:

  • Lines and wrinkles: Fine lines appear first, often around the eyes and mouth, then deepen into wrinkles over time. They form both from repeated expressions and from the loss of collagen.
  • Loss of volume and firmness: As collagen, fat and bone change, the face loses some of its support. This leads to sagging and slackness, especially around the cheeks, jawline and neck.
  • Rough or uneven texture: The skin can become drier and rougher, and pores may look more obvious. This reflects slower renewal and a weaker skin barrier.
  • Age spots and uneven tone: Years of sun exposure leave age spots and patchy skin tone. This kind of hyperpigmentation is a classic sign of photoageing.

How Does Skin Ageing Affect Skin of Colour?

The signs of ageing differ across skin tones. In richly pigmented skin, the extra melanin offers some natural protection from the sun. As a result, deep wrinkles and sagging often appear later than they do in lighter skin. However, uneven tone and dark patches tend to be the more prominent concern. Conditions like melasma and age spots are common, and they can be slow to fade. So an anti-ageing routine for deeper skin tones often centres on sun protection and even tone as much as it does on lines.

What are the Best Treatments for Skin Ageing?

Skin ageing cannot be stopped, but the right treatments slow it and improve how the skin looks. Most plans build up in layers, starting with skincare and sun protection. The most effective anti-ageing treatments are:

Skincare takes time to work, so it is worth giving any routine at least a few months before changing it. Professional skin procedures and injectables can augment the effects of skincare but require repeat treatments for maintenance. Surgery can yield the most dramatic results but it is expensive and carries many potential risks. As always, seek professional advice regarding the best options for your specific concerns, goals and lifestyle.

Can You Reverse Skin Ageing?

You cannot reverse skin ageing but it is possible to improve how your skin looks and feels. Sun protection and a good routine prevent further damage and can even repair some of it. Retinoids like tretinoin can help rebuild collagen as part of an anti-ageing skincare routine as well as certain professional treatments can help soften lines that have already formed. So although you cannot turn the clock back, you can slow it down and look your best at any age.

How Can You Prevent Skin Ageing?

Prevention is the most powerful anti-ageing tool, and it is never too early or too late to start. The single most important step is daily sunscreen, since the sun drives most preventable ageing. Wear SPF 30 or higher every day, even when it is cloudy. A healthy lifestyle helps too, so it is worth not smoking, eating well and sleeping properly. A consistent anti-ageing skincare routine with antioxidants and a retinoid can help improve skin quality and address wrinkles, texture and uneven skin tone. Starting these habits early gives the biggest payoff, but they help at any age.

Frequently asked questions

Skin begins to age earlier than most people expect. Collagen production starts to decline from the mid-20s, although the first visible fine lines often appear in the late 20s or 30s. How quickly it shows depends on your genes, your sun exposure and your lifestyle.

While you cannot entirely reverse skin ageing, you can significantly reduce and manage its visible signs. This can be achieved through a combination of a healthy lifestyle, a well-tailored skincare routine, and in some cases, dermatological treatments.

Exposure to the sun's ultraviolet (UV) light accounts for approximately 90% of the symptoms of premature skin ageing. UV light damages the elastin fibers in the skin, causing it to sag, stretch, and lose its ability to snap back after stretching.

Smoking can accelerate the skin ageing process. The toxins in smoke can damage collagen and elastin, leading to wrinkles and a dull, sallow complexion.

Staying hydrated is good for your skin and your overall health, but drinking water alone does not prevent wrinkles. Wrinkles are driven mainly by collagen loss and sun damage. Topical actives and daily sun protection do far more to keep skin smooth.

Yes, diet can significantly impact skin ageing. Eating a diet rich in antioxidants, vitamins, and proteins can help combat oxidative stress that contributes to skin ageing.

Creams with proven actives do make a real difference, within limits. Retinoids, vitamin C and sunscreen can soften fine lines, even out tone and slow further ageing. They will not match the results of a procedure, but they are the foundation of any anti-ageing routine.

Many people start a retinoid in their late 20s or early 30s, as collagen begins to decline. There is no strict rule, and starting later still brings clear benefits. Sun protection, on the other hand, matters from childhood onwards.

It's never too late to start a skincare routine. While prevention is ideal, many skincare products and treatments can help improve the appearance of your skin at any age.

Retinoids such as tretinoin and retinol have the strongest evidence for improving fine lines and texture. Vitamin C, peptides and exfoliating acids are useful supporting actives. Daily sunscreen, though, is the one product that does the most to keep skin looking young.

Fine lines are shallow and usually the first sign of ageing, often around the eyes and mouth. Wrinkles are deeper, more set creases that develop over time. Both are signs of skin ageing, driven by collagen loss and sun damage.

Yes, the same anti-ageing actives work for men. Men's skin tends to be thicker and can show lines a little later, but it ages in the same way. A simple routine of sunscreen and a retinoid suits most men well.
