Renewal, Healing & Scar Behaviour

CELLULAR RENEWAL, HEALING CYCLES, SCAR BEHAVIOUR & LONG-TERM YOUTH PRESERVATION

How your skin regenerates, repairs injury, reverses damage, clears imperfections and maintains youth across decades

THE SECRET TO SKIN AGEING IS NOT HOW MUCH COLLAGEN YOU HAVE… BUT HOW WELL YOU RENEW.

Every aspect of youthful skin — clarity, firmness, glow, even tone, smooth texture and strong barrier function — comes from ONE biological ability:

your skin’s capacity to renew itself.

Youthful skin renews fast.

Environmentally stressed or ageing skin renews slowly.

Clients often describe:

“My skin just doesn’t heal like it used to.”

“Marks stay for ages.”

“Breakouts leave long-lasting marks.”

“Lines appear faster.”

“My texture feels uneven.”

“My under-eyes look thinner.”

These are not random changes.

They are symptoms of slowed cellular renewal and disrupted healing cycles.

This page explains:

how your skin regenerates
why healing becomes slower with age
why scars form differently in different people
how inflammation changes healing outcomes
how hormones affect wound repair
how circulation controls speed of recovery
how stress impacts tissue renewal
how technology accelerates regeneration
how youth preservation depends on repair efficiency

Every treatment at Aeternitas works by enhancing the skin’s natural healing intelligence, not forcing artificial change.

THE 4 PHASES OF SKIN HEALING

Your skin repairs damage through a strict, beautifully coordinated 4-phase cycle.

When this cycle slows, ageing accelerates.

PHASE 1 — HEMOSTASIS (0–60 minutes)

The moment skin experiences stress (UV, injury, inflammation, irritation):

micro-capillaries constrict
clotting cascade activates
platelets release growth factors
immune cells activate
ATP demand increases

A healthy hemostasis phase prevents scarring and excessive inflammation.

PHASE 2 — INFLAMMATION (0–72 hours)

This phase is essential — small amounts of inflammation heal you.

Problems occur when:

inflammation lasts too long
inflammation becomes too intense
cytokines (IL-1, IL-6, TNF) rise excessively
melanocytes react and create PIH
collagen becomes damaged instead of repaired

Modern lifestyles cause chronic low-grade inflammation, slowing renewal.

PHASE 3 — PROLIFERATION (Day 2–21)

This is the “building” phase.

fibroblasts create new collagen
endothelial cells form new vessels (angiogenesis)
keratinocytes rebuild the epidermis
skin begins resurfacing
hydration pathways activate
barrier starts repairing

When this phase is efficient, skin looks:

clear
smooth
bright
firm

If sluggish → dullness + pigment + rough texture + slower healing.

PHASE 4 — REMODELLING (Day 21–1 year)

Collagen reorganises, strengthens and aligns.

scars flatten
texture becomes smoother
firmness increases
elasticity improves
structural youth is restored

This is the phase most people underestimate.

Aeternitas devices amplify this phase dramatically — which is why results continue improving for months.

AGEING IS ACTUALLY SLOWED HEALING

Clients believe ageing = loss of collagen.

This is only partly true.

The deeper truth:

Ageing = slower healing, slower turnover, slower collagen repair.

After age 25:

cell turnover slows
fibroblasts become weaker
antioxidant capacity decreases
inflammatory responses intensify
mitochondrial ATP decreases
melanin becomes dysregulated
barrier recovery slows

This page shows how Aeternitas reactivates these systems.

CELL TURNOVER SPEED (THE REAL AGE INDICATOR)

Youthful skin renews every 28 days.

Ageing skin renews every 45–90 days.

Turnover speed affects:

glow
pigmentation
smoothness
breakouts
scarring
moisture
texture
radiance
overall youthfulness

Aeternitas accelerates turnover by restoring mitochondrial function, improving oxygenation and stimulating controlled regeneration.

SCAR BEHAVIOUR

Not all scars behave the same.

Atrophic Scars

acne scars
ice-pick scars
boxcar scars
rolling scars

Caused by:

collagen loss
poor fibroblast activity
inflammation
delayed proliferation phase

RF + Secret RF + HIFU = strongest combination.

Hypertrophic Scars & Keloids

Caused by:

excessive fibroblast activity
genetic predisposition
increased TGF-β signalling
high inflammation

980+ + LED + targeted RF reduces thickness and inflammation

Pigmented Scars

Caused by:

post-inflammatory hyperpigmentation
melanocyte activation
slow turnover
hormonal triggers

RF + LED + 980+ = pathway correction.

COLLAGEN QUALITY VS QUANTITY

Ageing is not just “less collagen.”

It is disorganised collagen.

Environmental stress, hormones, inflammation and glycation all damage:

fibre alignment
fibre strength
elasticity
hydration matrix (GAGs)

Aeternitas devices create younger-quality collagen — tighter, stronger, more resilient.

THE EPIDERMAL BARRIER & RENEWAL

Barrier recovery is essential to long-term youthfulness.

A weak barrier:

increases inflammation
slows healing
worsens pigmentation
increases redness
reduces hydration
accelerates surface ageing

Aeternitas:

strengthens ceramides
increases barrier proteins
reduces inflammation
supports healthy renewal

GENDER DIFFERENCES IN HEALING & RENEWAL

Female Skin

heals slower during hormonal shifts
higher PIH risk
more inflammation during PMS/perimenopause
barrier becomes weaker post-menopause
pigment becomes more reactive

Male Skin

heals faster initially
but environmental damage accumulates deeper
deeper wrinkles form suddenly
sebum oxidation slows renewal

Transgender Clients

Oestrogen therapy:

increases pigment sensitivity
reduces oil production
increases dehydration risk
slows wound healing slightly

Testosterone therapy:

increases sebum oxidation
increases inflammation → more PIH
strengthens dermis → deeper scar risk

All of this informs Aeternitas treatment planning.

DEEP BIOLOGY OF RENEWAL & REGENERATION

Fibroblasts • Keratinocytes • Growth Factors • ECM • SMAS Healing • Gene Expression • Scar Biology • Ageing Repair Decline

FIBROBLASTS: “THE ARCHITECTS OF YOUTH”

Fibroblasts build and maintain your skin’s deeper structure.

They produce:

Collagen types I & III (firmness + strength)
Elastin (elasticity + recoil)
Glycosaminoglycans (hydration + plumpness)
Matrix proteins (support network)
Growth factors (healing signals)

When fibroblasts are healthy:

wounds heal faster
fine lines fade
texture improves
structure becomes firmer
scars flatten

AGEING AFFECTS FIBROBLASTS SEVERELY

After age 25:

fibroblasts become smaller
their energy (ATP) declines
collagen production slows
the ECM becomes fragmented
elastin becomes disorganised
damaged fibroblasts replicate weakly

This is why ageing accelerates after 30–35.

KERATINOCYTES: “THE SURFACE RENEWAL SYSTEM”

Keratinocytes repair and regenerate the epidermis.

Their job:

rebuild the surface
restore barrier proteins
close breaks in the skin
shed pigment
create a smooth, even texture

Keratinocyte turnover controls:

glow
pigmentation fading
smoothness
brightness
softness
hydration

AGEING IMPACT

With age:

keratinocyte turnover slows
pigment stays longer
texture looks uneven
healing slows
surface dullness becomes constant
barrier recovers more slowly

This is why marks linger for weeks rather than days.

GROWTH FACTORS (THE ORDER-GIVERS)

Growth factors are the “commands” that tell cells what to do.

Key growth factors:

TGF-β → controls collagen building
EGF → increases renewal + healing
VEGF → blood vessel formation
PDGF → recruits fibroblasts
FGF → elasticity + hydration
IGF → accelerates repair
KGF → strengthens the epidermis

AGEING IMPACT

Growth factor signalling weakens:

fewer signals → slower renewal
weaker collagen rebuilding
less elastin repair
poorer wound quality
higher risk of scarring
pigment persists longer

EXTRACELLULAR MATRIX (ECM): “THE SKIN’S INTERNAL SCAFFOLD”

The ECM is the support network that holds everything together.

It includes:

collagen
elastin
hyaluronic acid
proteoglycans
water
structural proteins

Environmental ageing, UV and inflammation damage the ECM through:

fragmentation
dehydration
stiffening (glycation)
inflammation
oxidative stress

A weak ECM = sagging, wrinkles, dullness, poor healing.

WOUND HEALING GENETICS

Healing is controlled by gene expression.

Key healing genes:

COL1A1/COL1A2 → collagen formation
HAS2 → hyaluronic acid production
ELN → elastin formation
MMPs → collagen breakdown
TIMPs → inhibit MMPs
IL-1, IL-6, TNF → inflammation
MITF → pigment regulation

AGEING = GENE BEHAVIOUR CHANGES

With ageing:

collagen genes decrease
elastin genes become unstable
MMP genes increase (more breakdown)
pigment genes over-activate
inflammation genes stay elevated
antioxidant genes weaken

All of this slows repair and increases visible ageing.

THE SKIN BARRIER & REPAIR BIOLOGY

Barrier repair requires:

ceramides
cholesterol
fatty acids
tight junction proteins
filaggrin
hydration

Damage to the barrier slows everything:

inflammation rises
redness increases
healing slows
sensitivity increases
pigment worsens
dryness becomes chronic
texture becomes rougher

Barrier repair is a central part of youth preservation.

SCAR FORMATION: WHY SOME PEOPLE SCAR & OTHERS DON’T

Scars form when the healing phases become unbalanced.

ATROPHIC SCARS

(indented)

Caused by:

weak fibroblasts
low collagen production
chronic inflammation
poor angiogenesis
delayed proliferation phase

HYPERTROPHIC SCARS

(raised)

Caused by:

excessive TGF-β
excessive fibroblast activity
poor ECM organisation
excessive inflammation

KELOIDS

(expanding raised scars)

Genetically driven abnormalities:

hyperactive fibroblasts
abnormal collagen deposition
excess growth factors
stronger inflammatory response

PIGMENTED SCARS

Caused by:

melanocyte activation
inflammation
slow turnover
vascular activity under pigment
hormonal influence

All scars result from healing imbalance.

ANGIOGENESIS (BLOOD VESSEL FORMATION)

Healthy healing requires new blood vessels.

Angiogenesis:

delivers oxygen
brings nutrients
supports fibroblast activity
speeds wound closure
removes waste
reduces risk of scarring

With age:

angiogenesis becomes slower
oxygen delivery drops
healing weakens
scars worsen
pigment becomes darker over scars

This is why older skin heals differently.

MITOCHONDRIA & REGENERATION

Healing requires energy.

Mitochondria supply ATP — the currency cells use for repair.

When ATP is low:

healing slows
fibroblasts work poorly
pigment stays longer
inflammation lasts
scar risk increases
renewal slows
texture worsens

LED + RF + HIFU all restore mitochondrial capacity.

AGE, HORMONES & RENEWAL

Female Biology

Perimenopause → major repair decline:

less oestrogen → weaker collagen
slower healing
pigment more reactive
barrier more fragile
higher PIH risk

Male Biology

Men retain collagen longer but:

environmental oxidation is higher
sebum oxidation affects healing
sudden deep wrinkles form later

Transgender Clients

Oestrogen therapy:

increases melanocyte sensitivity
increases vascular activity
increases hydration needs
slows barrier recovery

Testosterone therapy:

increases inflammation → slower healing
increases PIH risk
thickens dermis → deeper scars

Aeternitas protocols must adjust per biological profile.

HOW AETERNITAS TECHNOLOGY ACCELERATES RENEWAL & CORRECTS SCAR BEHAVIOUR

Collagen remodelling • controlled micro-injury • ATP restoration • fibroblast activation • angiogenesis • scar flattening • long-term youth preservation

EXFU 11D HIFU

Structural Healing • Deep Collagen Renewal • Long-Term Regeneration

HIFU accelerates renewal by stimulating controlled thermal coagulation zones at precise depths (SMAS, deep dermis, mid-dermis).

BIOLOGICAL EFFECTS

activates fibroblasts at multiple layers
increases collagen I and III
re-aligns collagen fibres
encourages long-term remodelling
stimulates SMAS tightening (improves contour healing)
improves oxygen delivery → better wound repair
improves circulation → better regenerative surface outcomes
reduces fine lines caused by poor healing

WHY THIS MATTERS

Healing requires coordinated collagen production and alignment.

HIFU restores the architecture that makes healing smoother, scars flatter and ageing slower.

BEST FOR

long-term rejuvenation
improving scar texture (rolling/boxcar)
accelerating healing in ageing skin
neck and jawline structural repair
restoring firmness after pigment or inflammation damage

EXFU 980+ RF MICRONEEDLING

Controlled Regeneration • Fibroblast Activation • Scar Remodelling

RF Microneedling is the most powerful regeneration tool in the Aeternitas Suite.

BIOLOGICAL EFFECTS

stimulates controlled dermal micro-injury
forces rapid fibroblast activation
increases growth factor release (PDGF, FGF, VEGF)
accelerates proliferation → faster healing
breaks down scar tissue
remodels collagen fibres
flattens atrophic scars (ice-pick, rolling, boxcar)
strengthens epidermal–dermal junction
increases angiogenesis (new vessels = faster renewal)

WHY THIS MATTERS

Ageing skin heals slowly because it lacks stimulus.

RF re-trains the skin to behave like younger tissue.

BEST FOR

acne scars
uneven texture
prolonged healing
pigmentation sitting over scars
deeper fine lines
enlarged pores
slow turnover

SECRET RF

Targeted Healing for Thin, Sensitive, or High-Risk Skin Types

Secret RF delivers RF energy more gently, making it ideal for:

under-eyes
thin skin
reactive skin
melasma-prone skin
sensitive post-inflammatory scars

BIOLOGICAL EFFECTS

improves fine texture
gently remodels atrophic scars
strengthens fragile skin
accelerates epidermal renewal
reduces vascular redness sitting under scars
improves dermal structure without harsh downtime

WHY THIS MATTERS

Some clients require precise, non-disruptive regeneration to prevent PIH or redness.

Secret RF is the safest advanced regeneration tool.

DERMALUX LED

ATP Enhancement • Inflammation Control • Wound Healing Acceleration

LED is the backbone of renewal therapies because it targets the energy system that powers healing.

BIOLOGICAL EFFECTS

increases ATP → speeds every phase of healing
reduces inflammatory cytokines (IL-1, IL-6, TNF)
accelerates keratinocyte turnover
improves pigment shedding
reduces redness & swelling
promotes angiogenesis
supports collagen remodelling
strengthens the barrier

WHY THIS MATTERS

Slow healing = slow results.

LED amplifies every other Aeternitas technology.

BEST FOR

sensitive skin
inflammation-prone skin
scarring with redness
post-RF or post-HIFU healing
clients with slow recovery cycles

CRYO COLD HAMMER

Heat Regulation • Inflammation Reduction • Post-Treatment Healing Stability

Cryo is essential for controlling inflammation during healing.

BIOLOGICAL EFFECTS

reduces post-treatment heat
calms microvascular dilation
reduces inflammation
reduces PIH risk
stabilises sensitive or reactive skin
reduces swelling
improves comfort
enhances surface healing

WHY THIS MATTERS

Chronic heat and inflammation slow renewal dramatically.

Cryo ensures a healthy inflammation window without overheating.

BEST FOR

melasma-prone clients
high PIH-risk clients
sensitive skin
post-RF cooling
reducing redness during regeneration

EXFU 980+ VASCULAR & PIGMENT CORRECTION

Scar Colour Correction • Redness Reduction • Vascular Healing Support

Scars, especially new ones, often contain:

excess blood vessels
redness
inflammatory cytokines
heat
uneven pigment

980+ corrects all of these.

BIOLOGICAL EFFECTS

collapses overactive scar vessels
reduces redness
reduces heat-driven pigment
calms inflammation around scars
increases oxygenation
prevents pigment from settling in scars
improves scar colour blending

WHY THIS MATTERS

Scar appearance is 40% colour, not just texture.

Correcting vascular behaviour is essential for scar refinement.

THE AETERNITAS REGENERATION SEQUENCE

The only complete multi-layer regeneration approach:

STEP 1 — CONTROL INFLAMMATION

LED + Cryo → regulate inflammation to avoid damage.

STEP 2 — ACTIVATE FIBROBLASTS

RF Microneedling → controlled regeneration at depth.

STEP 3 — CORRECT SCAR COLOUR

980+ → reduce redness + prevent PIH.

STEP 4 — RESTORE STRUCTURE

HIFU → improve dermal/SMAS architecture for long-term support.

STEP 5 — ENHANCE ENERGY

LED → increase ATP to drive fast, clean healing.

STEP 6 — MAINTAIN THE RESULT

LED + Cryo → protect new tissue from environmental triggers.

WHY AETERNITAS REGENERATION IS SUPERIOR TO SINGLE-TECHNOLOGY APPROACHES

Most clinics treat scars or renewal with one device.

This misses half the biology.

Scars involve:

collagen
elastin
pigment
inflammation
vascular triggers
oxygenation
fibroblast behaviour

Aeternitas treats ALL layers:

✔ Structure (HIFU)

✔ Deep regeneration (RF)

✔ Sensitive-area repair (Secret RF)

✔ Energy + mitochondria (LED)

✔ Heat + redness control (Cryo)

✔ Vascular correction (980+)

This is why clients experience:

smoother texture
faster healing
flatter scars
lighter pigmentation
stronger barrier
visibly younger skin

CLIENT LEARNING — “Why Your Healing Slowed, Why Scars Behave Differently Now, and How You Can Regain Youthful Regeneration.”

Clients often tell us:

“My skin doesn’t heal like it used to.”

“Marks stay for months instead of days.”

“I break out and the mark stays for ages.”

“My scars are more visible than before.”

“My texture is getting rougher.”

“I feel like the smallest thing leaves a mark now.”

These concerns are not imagined.

They are real biological changes happening inside your skin — and they can be reversed.

This page explains why your healing slows, why scars behave differently, and why renewal is the true source of youthfulness.

YOUR SKIN IS NOT “WEAK.” IT IS WORKING HARDER THAN EVER.

As we age, the body deals with:

more inflammation
more hormonal fluctuation
more stress
less sleep
more environmental damage
reduced antioxidant capacity
slower cell turnover
weaker circulation

Your skin is not failing you — it is overloaded.

This overload slows down every step of healing.

WHY MARKS STAY LONGER NOW

You may have noticed:

spots leaving brown marks
scratches turning into pigmentation
irritation leaving longer redness

This happens because:

turnover is slower
melanocytes become more reactive
inflammation lasts longer
circulation slows
collagen rebuilds more slowly
the barrier is weaker

As a result, any small disruption leaves a visible “memory.”

WHY SCARS FORM DIFFERENTLY AS YOU AGE

In younger years, wounds heal smoothly.

With age:

fibroblasts weaken
collagen becomes disorganised
inflammation increases
angiogenesis slows
pigment becomes more reactive
healing phases become unbalanced

This leads to:

deeper lines
uneven texture
atrophic acne scars
pigmentation inside scars
redness that won’t settle
“hollowed” healing
poorly blended scars

This is not your fault — it is biology.

WHY YOU HEAL SLOWLY WHEN STRESSED, TIRED OR HORMONALLY CHANGING

If you’ve ever noticed:

“I heal slower when I’m stressed.”

“My skin acts differently around my cycle.”

“Healing is worse during menopause.”

“My scars look darker when life is hectic.”

It’s because:

cortisol slows healing
stress increases inflammation
hormones activate pigment
sleep loss reduces growth factors
circulation drops
immune activity alters
barrier weakens

Your healing speed is directly tied to your lifestyle and hormone rhythm — not just age.

WHY TEXTURE GETS ROUGHER WITH TIME

Rough texture comes from:

slower cell turnover
poor collagen alignment
weakened hyaluronic acid levels
accumulated environmental damage
past inflammation
micro-scarring
barrier dehydration

This creates the appearance of:

enlarged pores
rough patches
uneven tone
bumpy surface
fine lines
dullness

Technology restores smoothness by accelerating renewal.

WHY UNDER-EYES APPEAR THINNER

The under-eye area heals slower because:

collagen is naturally low
skin is thin
circulation is weaker
environmental stress is higher
hormonal shifts reduce elasticity
pigmentation or vascular reactivity increases

With age, these changes amplify quickly.

WHY AGEING IS REALLY “SLOW HEALING”

Most visible ageing is not age — it is slow repair.

When healing slows:

pigment stays
lines deepen
scars form
texture worsens
glow fades
barrier weakens
redness increases
collagen breaks down
elasticity drops

This is why Aeternitas treatments focus on accelerating healing, not just adding collagen.

HOW AETERNITAS RESTORES YOUTHFUL HEALING

Aeternitas uses a multi-layered regeneration system:

✔ RF Microneedling

deep regeneration + fibroblast stimulation

✔ Secret RF

safe regeneration in sensitive/thin areas

✔ LED

ATP boost + inflammation control + faster healing

✔ Cryo

heat control + reduced redness + reduced PIH risk

✔ 980+

vascular correction + redness reduction + scar colour blending

✔ HIFU

deep structural renewal + improved oxygenation + long-term collagen organisation

Combined, these restore youthful healing patterns.

REAL AGEING CONTROL STARTS WITH RENEWAL, NOT PRODUCTS

Skincare can support your surface.

Regeneration resets your biology.

When your healing accelerates:

scars fade
marks disappear faster
texture smooths
pigment lightens
collagen becomes organised
wrinkles soften
elasticity improves
youthfulness returns

Clients often describe the change as:

“My skin feels alive again.”

“That hollow, tired look has gone.”

“Everything heals so much faster now.”

That is regeneration in action.
