Cycles, Gender & Ethnic Patterns
HORMONAL CYCLES, GENDER & ETHNIC PATTERNS
(Why hormonal ageing affects every client differently — and what patterns always repeat)
HORMONAL CYCLES SHAPE SKIN BEHAVIOUR MORE THAN AGE
Unlike chronological ageing, hormonal ageing is:
- cyclical
- fluctuating
- variable
- episodic
- predictable
- biologically forceful
This is why clients often say:
“My skin changes every month.”
“My skin looks different every morning.”
“My skin looks amazing some days and awful the next.”
“I aged in just one year — what happened?”
“I react to things I never reacted to before.”
Hormonal cycles explain it.
FEMALE HORMONAL CYCLES & THEIR EFFECTS ON THE SKIN
Female skin changes every 28 days, with four biologically distinct phases:
Menstrual Phase (Days 1–5)
Hormones: low oestrogen + low progesterone
Skin effects:
- dullness
- dryness
- sensitivity
- slower healing
- increased redness
- low resilience
- mild swelling
- reduced glow
Best supportive treatments:
- LED
- Cryo
- gentle RF (if skin is stable)
Follicular Phase (Days 6–13)
Hormones: rising oestrogen
Skin effects:
- improved firmness
- stronger barrier
- hydration improves
- glow increases
- best repair window
Best treatments:
- RF Microneedling
- Secret RF
- HIFU
- LED
This is the most collagen-responsive part of the cycle.
Ovulation Phase (Days 14–16)
Hormones: peak oestrogen + LH surge
Skin effects:
- highest luminosity
- tightest pores
- best healing
- reduced inflammation
- increased collagen potential
Best treatments:
- HIFU (excellent results window)
- RF Microneedling
- LED
Luteal Phase (Days 17–28)
Hormones: rising progesterone, fluctuating oestrogen
Skin effects:
- increased oil
- inflammation increases
- redness
- breakouts
- pigment risk increases
- slower healing
- PMS-related flushing
Best treatments:
- LED
- Cryo
- Vascular 980+ (if redness patterns worsen)
During this phase, avoid aggressive RF or HIFU if the client is inflamed or sensitive.
MALE HORMONAL STABILITY — AND HIDDEN AGEING TRIGGERS
Men do not have a monthly cycle.
However, they do experience:
- testosterone fluctuations (daily + weekly)
- stress-related cortisol spikes
- sleep-related skin changes
- slow, steady reduction in collagen
- later but more dramatic sagging
- deeper folds due to heavier fat pads
Men typically require higher energy and deeper penetration in collagen-focused devices, but they are also:
- more vascular
- more redness-prone post-procedure
- more prone to “heavy-set” ageing in the lower face
RF + HIFU are particularly effective in men.
TRANSGENDER CLIENT HORMONAL PATTERNS
MTF (Male-to-Female)
Oestrogen therapy shifts:
- skin becomes thinner
- barrier strengthens
- pigment may increase
- inflammation increases temporarily
- oil reduces
- under-eye area becomes fragile
- dermis resembles female biology
- structural ageing pattern becomes feminine
Skin behaviour becomes more sensitive and needs:
- LED
- Secret RF
- controlled RF energy
- tailored HIFU
FTM (Female-to-Male)
Testosterone therapy shifts:
- oil increases
- acne may worsen
- jawline inflammation increases
- collagen density increases
- barrier becomes stronger
- thicker dermal structure develops
Skin becomes more resilient but also more:
- breakout-prone
- inflamed
- scar-prone
RF Microneedling + Vascular + LED are essential.
ETHNICITY & HORMONAL INTERACTION — HOW DIFFERENT SKINS REACT
Different ethnic groups have different hormonal-skin responses because:
- melanin concentration
- collagen fibre thickness
- ECM hydration
- oil activity
- genetic inflammatory pathways
- vascular reactivity
- fibroblast density
- barrier behaviour
…all vary by skin type.
Fitzpatrick I–III (lighter skin types)
Hormonal effects include:
- more visible redness
- more flushing
- more vascular sensitivity
- thinner dermis
- less melanin protection
- higher progesterone sensitivity
Hormonal phases cause dramatic visible changes.
Fitzpatrick IV–VI (medium–deep skin)
Hormonal effects include:
- deeper inflammation
- less visible flushing
- higher pigment response
- stronger fibroblast signalling
- slower resolving brown marks
- increased PIH risk
Hormone-triggered pigmentation is common:
- pregnancy
- menopause
- stress
- insulin fluctuations
RF + LED must be used with pigment-safe protocols.
THE THREE UNIVERSAL HORMONAL AGEING PATTERNS
Across all genders and ethnicities, ageing follows three predictable hormonal pathways:
The Oestrogen Decline Pattern
Seen in:
- women 35–65
- MTF on long-term oestrogen
Results in:
- collagen loss
- laxity
- under-eye thinning
- crepey skin
- deeper wrinkles
- rapid neck ageing
The Cortisol-Inflammation Pattern
Seen in:
- all genders
- high-stress clients
- sleep-deprived clients
- burnout
- perimenopause
- chronic illness
Results in:
- redness
- sensitivity
- accelerated ageing
- slow healing
- pigment worsening
- tired appearance
Aeternitas technologies focus heavily on correcting Pattern 3.
HORMONES DICTATE HOW THE SKIN RESPONDS TO TREATMENT
This is one of the most important truths:
Different hormonal profiles = different treatment responses.
Oestrogen decline → needs structural rebuilding
Best:
- HIFU
- RF Microneedling
- LED
Androgen dominance → needs inflammation & oil regulation
Best:
- RF Microneedling
- 980+ Vascular
- LED
- Cryo
Cortisol elevation → needs immune stabilisation
Best:
- LED
- Cryo
- gentle RF
- vascular support
Thyroid imbalance → needs circulation + barrier support
Best:
- LED
- Cryo
- lymphatic support
