GENETICS, DNA & EPIGENETIC AGEING – Aeternitas Cosmetics

Genetic Traits That Shape Ageing

GENETIC TRAITS THAT SHAPE SKIN AGEING

(How your inherited blueprint shapes your skin — and how your environment, hormones, stress and treatments can modify it)

GENETICS — YOUR SKIN’S ORIGINAL BLUEPRINT

Your DNA determines your baseline for:

collagen density
elastin quality
fibroblast productivity
pigment behaviour
sensitivity threshold
vascular reactivity
oil activity
pore size
wound-healing capacity
inflammation behaviour
barrier strength

Genetics explain why:

some people naturally have thicker skin
some wrinkle early
some rarely break out
some develop pigment easily
some scar more easily
some flush strongly
some stay youthful for decades

However:

Genetics determine the starting point.

Epigenetics determine the outcome.

GENETIC VARIATION IN COLLAGEN & ELASTIN

Your genes decide how your collagen behaves:

how tightly fibres are organised
how resistant they are to breakdown
how active your fibroblasts are
how densely collagen is packed
how elastic your elastin fibres remain

Some people are genetically “high collagen responders.”

Their fibroblasts:

produce collagen faster
repair injuries more efficiently
resist glycation
maintain firmness longer

Others are genetically “low responders,” meaning:

slower collagen production
quicker breakdown
early fine lines
earlier laxity
thinner dermis
more rapid structural decline

But even low responders can dramatically improve through epigenetic activation — which is precisely what HIFU, RF Microneedling and LED do.

GENETIC VARIATION IN PIGMENT BEHAVIOUR

Genetics influence:

how melanocytes respond to light
how quickly pigment forms
how long it stays
how deep it travels
how inflammation affects pigment
how easily melasma develops

Clients genetically prone to pigment often:

develop sun spots younger
experience PIH more often
have stronger melanin rebound
see slower fading of marks

However:

Pigment genes can be stabilised.

Energy-based vascular, LED and RF modalities can interrupt the pathways that trigger pigmentation.

GENETIC VARIATION IN INFLAMMATION & REDNESS

Inflammation genes determine:

how strongly the skin reacts
how long inflammation lasts
whether redness becomes chronic
sensitivity levels
immune system overactivity
tendency toward rosacea-like behaviour

Some clients naturally mount strong inflammatory responses.

Others remain calm even under stress.

Hormones can intensify genetic inflammatory tendencies — especially progesterone, cortisol and testosterone.

LED and Cryo are essential modulators for genetically reactive skin.

GENETIC VARIATION IN SCARRING & WOUND HEALING

Your wound-healing genes influence:

how easily you scar
how collagen is laid down
whether scars become raised or indented
how smooth healing is
how long redness remains
whether pigmentation appears

This is critical for RF Microneedling and Secret RF clients.

However:

Epigenetic treatment sequencing can override slow genetic healing

by increasing ATP, fibroblast signalling and vascular repair.

GENETIC VARIATION IN OIL & BREAKOUT PATTERNS

Oil-production genes determine:

pore size
breakout likelihood
jawline acne severity
textural thickening
response to hormones
degree of inflammation
skin barrier density

Clients with genetically active sebaceous glands:

experience more hormonal acne
scar more frequently
struggle with persistent congestion

RF + LED + Cryo + 980+ are particularly effective for high-oil genetic profiles.

EPIGENETICS — HOW LIFE REPROGRAMS YOUR DNA

Epigenetics decide how your genes behave.

They turn genes:

ON (active)
OFF (silent)
UP (stronger behaviour)
DOWN (weaker behaviour)

Epigenetic triggers include:

stress
sleep
diet
sun exposure
pollution
inflammation
hormones
medication
trauma
smoking
alcohol
chronic dehydration
UV damage
emotional stress
long-term illness

In the skin, epigenetic triggers change:

collagen production rates
elastin quality
wound-healing speed
barrier function
pigment activity
vascular behaviour
inflammation signalling
sensitivity
breakout likelihood

This means:

Your skin at 40 is not simply the result of your genes — it is the result of gene expression choices made over 10, 20, 30 years.

And the most important insight:

Energy-based treatments can reverse negative epigenetic changes.

HOW STRESS AND CORTISOL MODIFY GENE EXPRESSION

Stress increases cortisol, which epigenetically:

switches ON inflammatory genes
switches ON pigment-activating genes
switches OFF collagen-building genes
switches OFF antioxidant genes
weakens barrier function
reduces fibroblast activity
accelerates overall biological ageing

This is why stress causes clients to say:

“I aged so quickly this year.”

“My skin just changed suddenly.”

“My face collapsed during stress.”

LED, Cryo and RF are essential in reversing cortisol-driven gene expression.

HOW HORMONES MODIFY GENE EXPRESSION

Hormonal changes influence:

collagen transcription genes
pigment-related genes (TYR, MITF pathways)
fibroblast signalling genes
elastin-assembly genes
inflammatory genes (IL-6, IL-8)
barrier lipid-production genes
wound-healing genes

This is why perimenopause and menopause cause sudden visible changes —

the genetic instructions have changed.

HIFU + RF + LED help restore youthful gene expression.

AGEING GENES VS BIOLOGICAL AGEING

Chronological ageing = your age in years.

Biological ageing = how your DNA behaves right now.

Biological ageing is influenced by:

mitochondrial efficiency
collagen transcription levels
inflammation load
epigenetic damage
hormonal environment
oxidative stress
immune balance

Some clients at 50 have a biological skin age of 35.

Some clients at 35 have a biological skin age of 50.

Aeternitas technologies aim to lower biological age, not just improve the surface.
