Skin longevity comes down to understanding what's happening beneath the surface, and giving your skin the support it needs to keep doing its job well, for longer.
That starts with two proteins: collagen and elastin.
What is collagen?
Collagen is the most abundant protein in your skin. Think of it as scaffolding, it gives skin its structure, thickness and firmness. Without enough of it, skin loses shape and starts to look thinner and less supported.
What is elastin?
Elastin is what lets skin stretch and return to its original shape. The easiest way to picture it: paper versus a rubber band. Crease a piece of paper and it stays creased. Stretch a rubber band and it snaps back. Elastin gives your skin that rubber band quality, the ability to move without holding onto every expression or crease permanently.
Together, collagen and elastin keep skin structurally young.
Why does collagen decline?
From around age 25, collagen production naturally starts to slow, dropping by approximately 1% each year. It's not dramatic in year one, but it compounds. By 40, that's roughly 15% of your peak collagen already gone, showing up as thinner skin, fine lines settling in, and a gradual loss of firmness.
It's a normal part of ageing. Understanding the timeline is what lets you support your skin ahead of time, rather than reacting to changes after they've shown up.
Can that decline be reversed?
Collagen decline compounds against you over time. Treatment works the same way, just in your favour.
Skin needling (also known as Collagen Induction Therapy) works by creating controlled micro-channels in the skin. This triggers your skin's own repair process, stimulating new collagen and elastin production from within, no toxins, no shortcuts.
Collagen and elastin production is a continual process, and results build session on session. That's why consistency, not a single treatment, drives skin longevity.
What does the research show?
Here's what the clinical research says about skin needling, after a full course of treatment:
Studies show that a course of skin needling increases:
-
- 400% collagen and elastin deposition
- 101% dermal density
- 28% skin elasticity
Sources: Aust et al., Plastic and Reconstructive Surgery, 2008. Kenkel et al., Aesthetic Surgery Journal, 2021. Results measured after a full course of treatment, not a single session.
How do we approach it?
At The Skin Bar, skin needling is our speciality, not one treatment on a long menu. Every plan is built around your skin's actual needs, typically 3 to 6 sessions, spaced 4 weeks apart, with a 6-session series as our clinical and commercial recommendation for the best, longest-lasting results. Once a course of treatments is complete, we recommend monthly sessions to continue to improve and compound your results.
You'll usually notice a glow within days. Real, structural change, the kind driven by new collagen and elastin, builds over 4 to 12 weeks as your skin rebuilds from within.
So what does this mean for you?
Collagen and elastin decline is inevitable. What you do about it isn't.
Skin longevity isn't a single appointment, it's a compounding investment in your skin's structure, built one session at a time.
