Collagen & elastin: your skin's scaffolding
If skin were a mattress, collagen would be the springs and elastin the elastic that lets it bounce back. Together they're why young skin looks firm and plump — and why we notice the change as they decline.
Why skin loses firmness
From our mid-twenties, the skin's own collagen gradually declines — which is what eventually shows as softening and early laxity. Firming treatments are designed to support that natural collagen over a course.
What they each do
Collagen is the most abundant protein in the body and the main structural fibre in the dermis — it provides strength and firmness, like scaffolding. Elastin is the stretchy partner that lets skin recoil back into place after it moves.
Woven through them is hyaluronic acid, which holds water and keeps the whole structure plump and hydrated. When all three are abundant, skin looks smooth, firm and dewy.
Why they decline
From our mid-twenties, the skin's own collagen production gradually slows — and existing fibres break down faster than they're replaced. Sun exposure is the single biggest accelerator (much of what we call ‘ageing’ is really sun damage), along with smoking, high sugar, stress and sleep.
As firm scaffolding is lost, skin softens, fine lines settle and it bounces back a little less readily — most visibly along the jawline, cheeks and neck.
Can it be supported?
You can't stop the clock, but you can support the skin's own renewal. Daily sun protection is the most powerful thing of all — it protects the collagen you have. Beyond that, collagen-stimulating treatments are designed to prompt the skin to make fresh collagen over a considered course, and good skincare and habits help hold it.
The honest framing is ‘support and maintain’, not ‘restore to twenty’ — realistic, gradual, and kept up over time.

Common questions
At what age does collagen start to decline?
Generally from the mid-twenties, gradually — it isn't a sudden drop. Sun exposure and lifestyle strongly influence how quickly it shows.
Does collagen powder or drinks rebuild my skin's collagen?
The evidence is mixed and modest. Ingested collagen is broken down in digestion, so it isn't delivered straight to your skin. It may play a supporting role, but it's not a substitute for sun protection and good skin habits.
What protects the collagen I still have?
Diligent daily sun protection, above everything else — plus not smoking, managing sugar, and sleeping well. These preserve existing collagen far more than any single product.
