Collagen Breakdown & Ageing Timelines
WHY STRUCTURE COLLAPSES
Decline, Damage Patterns & Collagen Loss Over Time
Collagen Loss — Exactly How Much
Yearly collagen loss (average adult):
1% per year
Menopause →
30% loss in the first 5 years
Perimenopause → accelerated weakening
Smoking → up to
20% faster breakdown
High sugar → stiffens collagen via glycation
UV damage → breaks collagen fibres instantly
This is why some clients age faster than others.
Collagen Types Affecting Your Skin
Your dermis contains primarily:
Type I Collagen
- 80–90% of total collagen
- strength, firmness, structure
Type III Collagen
- youthful collagen
- elasticity, softness
- high in younger skin
- declines dramatically with age
Rejuvenation treatments aim to:
- increase Type I collagen
- restore Type III collagen
This combination creates:
- lifting
- firming
- smoothing
- long-term rejuvenation
Collagen Maturation — The Timeline
After stimulation:
- Weeks 0–2 → inflammatory phase
- Weeks 2–6 → new collagen formation
- Weeks 6–12 → remodelling and strengthening
- Months 3–9 → maturation
- Months 9–18 → long-term structural lifting
This is why clients see:
✔ immediate tightening (due to heat contraction)
✔ progressive lifting over 3–9 months
✔ long-term structural improvement up to 18 months
Youthful vs Ageing Collagen
YOUTHFUL COLLAGEN
- tightly woven
- uniform
- hydrated
- resilient
- strengthened by Type III
- fast to repair
AGEING COLLAGEN
- loose
- disorganised
- dehydrated
- brittle
- sparse
- slow to repair
Treatments like HIFU and RF Microneedling force fibroblasts to rebuild collagen in a younger pattern, not an aged pattern.
THE AGEING OF COLLAGEN — A BIOLOGICAL TIMELINE
Collagen ageing is not random.
It follows a predictable biological timeline driven by hormones, inflammation, lifestyle, genetics and environmental damage.
AGE 20–25
- Peak collagen density
- Strong Type III collagen
- Fast healing
- Minimal elastin damage
- Thick dermal structure
AGE 25–35
- Collagen begins declining 1% per year
- Early micro-fragmentation starts
- First fine lines form under the eyes
- Barrier slows slightly
- Mild crepey texture in some clients
AGE 35–45
- Collagen decline accelerates
- Pigment inconsistencies appear
- Stiffened collagen (“glycated collagen”) increases
- Deeper wrinkles form in expression zones
- Early volume changes
- Neck texture becomes noticeable
- Hormonal shifts intensify breakdown
AGE 45–55
- Perimenopause causes sharp collagen decline
- Oestrogen drops alter skin hydration
- Elastin quality decreases
- Jawline softens
- Neck-laxity becomes more evident
- Crepey texture around eyes dramatically increases
AGE 55–70
- Up to 30–50% collagen loss
- Dermal thinning
- Fibroblasts partially dormant
- Lifting changes are more structural than superficial
- Skin responds beautifully to correct stimulation, but slower
- Long-term maintenance becomes essential
Fibroblast Decline — The Core of Structural Ageing
Fibroblasts age faster than almost any other skin cell.
WHY THEY DECLINE
- oxidative stress
- hormonal decline
- UV damage
- chronic inflammation
- glycation
- mitochondrial exhaustion
- low ATP
- mechanical stress
- sleep deprivation
WHAT HAPPENS WHEN THEY DECLINE
- collagen production drops
- elastin becomes sparse
- ECM weakens
- wound healing slows
- inflammation increases
- texture becomes rough
- crepey skin emerges
- sagging accelerates
DORMANT FIBROBLASTS
After age 50–60, fibroblasts may become senescent:
- alive
- present
- BUT inactive
This is one of the reasons aged skin seems to “stop responding”.
💡 BUT GOOD NEWS:
Fibroblasts can be reactivated with correct stimulus —
through heat, micro-injury, ATP increases, and mechanical energy.
ECM Damage Patterns
The ECM is highly sensitive to:
- UV Damage
- breaks collagen
- disrupts elastin
- weakens hyaluronic acid
- increases MMP enzymes that dissolve collagen
- Glycation (Sugar Damage)
- stiffens collagen
- makes fibres brittle
- accelerates lines & crepey texture
- common in diets high in sugar, alcohol, white carbs
- Inflammation
- chronic inflammation degrades the ECM
- increases enzymes that break down collagen
- causes premature ageing
Hormonal Decline
- less oestrogen = weaker collagen
- less testosterone = reduced density
- HRT changes collagen behaviour depending on protocol
Oxidative Stress
- pollution, smoking, stress
- causes micro-fibre breaks
- makes collagen weaker
Mechanical Stress
- repetitive movement
- compression during sleep
- rubbing
- poor facial posture
All of these accumulate over decades.
The ECM collapses in micro-regions, not evenly.
This is why:
- nasolabial region weakens faster
- jawline weakens faster
- under-eye region collapses more quickly
- neck ages differently from face
Elastin Ageing — Why Crepey Texture Forms
Elastin fibres behave differently to collagen:
- they do not regenerate easily
- damage shows as fine, crinkled crepey texture
- especially on the eyes, neck and upper chest
- glycation stiffens elastin
- UV destroys elastin rapidly
Elastin also declines more rapidly in:
- lighter ethnicities
- clients with high UV exposure
- post-menopausal women
- clients with high sugar intake
- clients with chronic inflammation
- clients with high cortisol stress
Crepey texture is the signature symptom of elastin decline.
Hyaluronic Acid — The Water Matrix of Youth
HA binds water into the ECM.
HA:
- gives plumpness
- smooths surface texture
- supports collagen fibres
- keeps the dermis hydrated
- improves glow
With age:
- HA declines
- water escapes
- ECM dries
- skin appears thin
- texture becomes rougher
LED + microneedling can increase HA through fibroblast stimulation.
The Collagen Ageing Triangle
Three processes drive visible age-related changes:
🔺
- Fibre Breakdown
(collagen dissolves faster)
🔺
- Fibre Weakening
(collagen becomes disorganised)
🔺
- Fibre Stiffening
(glycation hardens collagen)
These create:
- deeper wrinkles
- sagging
- jowls
- hollows
- crepey texture
- dullness
The goal of Aeternitas treatments is to reverse all three.
Fibroblasts do not activate spontaneously.
They only rebuild collagen and elastin when triggered by:
- controlled thermal injury
- mechanical stimulation
- electrical/EM field excitation
- ATP-boosting light energy
- micro-injury to the dermis
- SMAS-level tissue contraction
This is why skincare alone cannot repair structural ageing.
Aeternitas technologies create the exact biological environment fibroblasts require to awaken, multiply, reorganise and rebuild the ECM.
