How skin ages (collagen & volume)

How skin changes with age? Collagen, elastin and facial volume, and the factors that influence it. 

How skin ages: collagen, volume and what's really happening

Skin ageing is often talked about as if it’s just about lines. In reality, several things are changing at once — in the skin, and in the structures beneath it. Understanding how skin ages makes it much easier to have a realistic, unhurried conversation about what, if anything, you’d like to do.

This is general information, not medical advice. How your skin ages is individual and best reviewed in person.

The building blocks: collagen and elastin

Two proteins do a lot of the heavy lifting for firm, resilient skin. Collagen gives skin its structure and support; elastin allows it to stretch and spring back. Together they act like the scaffolding and the elastic of the skin.

From our mid-twenties onward, we gradually produce less of both, and the fibres we already have become less organised over time. There’s also a slow decline in the skin’s ability to hold water, which is why skin can feel drier and less plump as the years pass. The cumulative result is skin that’s a little less firm, less bouncy and less dewy than it once was — a gradual shift rather than a sudden change.

The face is more than skin

Here’s the part that surprises people: much of what we read as “ageing” isn’t happening in the skin at all. The face is built in layers — skin on the outside, then fat pads, muscle, and bone underneath.

With time, the fat pads that give the face its softness and support shift downward and lose some of their volume. Muscle activity leaves its mark, and even the underlying bone changes subtly. So the things people commonly notice — softening along the jawline, deeper folds between the nose and mouth, a flatter or more tired look around the eyes — are often about structure and volume, not just surface lines. That’s an important distinction, because surface concerns and structural concerns are understood quite differently.

Intrinsic vs extrinsic ageing

It helps to split ageing into two kinds:

  • Intrinsic ageing is the natural, genetically programmed process — the gradual decline in collagen, elastin and volume that happens to everyone over time. You can’t stop it, and there’s nothing wrong with it.
  • Extrinsic ageing is the part driven by external factors — sun, lifestyle and environment. This is the portion you have the most influence over.


Most of what we see in the mirror is a blend of the two, but the extrinsic share is often larger than people expect — which is actually good news, because it’s the part that responds most to everyday habits.

What speeds it up

Genetics set the baseline, but lifestyle has a real say. The biggest external factor by far is sun exposure, a leading contributor to visible skin ageing and especially relevant in the Queensland climate. Beyond the sun, the usual suspects all play a part:

  • Smoking, which affects collagen and circulation.
  • Poor sleep and high stress over long periods.
  • Dehydration and diet.
  • Repeated, unprotected UV — the common thread through much of the list.

The encouraging flip side: the factors that speed ageing up are largely the same ones you can soften with consistent basics.

Signs people commonly notice

Everyone’s experience is different, but the changes people tend to mention include a loss of firmness, fine lines becoming more visible, a duller or uneven tone, dryness, and a general sense that the face looks more tired or less “lifted” than before. None of these are problems to be fixed — they’re simply changes, and how much any of them matters is entirely up to you.

What genuinely helps day to day

Long before any treatment enters the conversation, a few habits do more than most people realise:

  • Daily broad-spectrum SPF — the closest thing there is to a foundation for healthy skin over time.
  • A simple, consistent skincare routine, suited to your skin rather than to trends.
  • Sleep, hydration and not smoking, which quietly support the skin’s own repair.

This isn’t a treatment plan and it doesn’t promise a particular outcome. It’s the baseline that makes everything else more worthwhile.

A few common myths

  • “It’s all about wrinkles.” As above, structure and volume are often the bigger story.
  • “Expensive creams rebuild collagen dramatically.” Good skincare supports the skin, but claims should be treated with healthy scepticism.
  • “Ageing is something to fight.” It’s a normal process. Whether you do anything about it is a personal choice, not an obligation.

Why it's personal

  • Two people the same age can be ageing quite differently, and how much any of it matters is entirely individual. There’s no “should” here. What’s realistic and worthwhile depends on your skin, your features and your goals — which is why it’s reviewed clinically and in person, never from a page.

How it's assessed at Refine

  • A consultation starts with understanding what you’re noticing, and why. A clinical assessment looks at your skin quality, firmness and facial structure as a whole — not one feature in isolation. From there, any options are discussed privately and conservatively, with honest, realistic expectations and the risks explained. Nothing is decided on the spot, individual results vary, and suitability is always assessed first.

A better first step

  • If you’re curious about how your skin is changing, the most useful thing isn’t a treatment — it’s an assessment and an honest conversation, in your own time.
