The Healing Cycle & Turnover Speed
The 4 Phases of Healing — And Why Ageing is Slower Repair
Fibroblasts • Keratinocytes • Growth Factors • ECM • SMAS Healing • Gene Expression • Scar Biology • Ageing Repair Decline
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.
