How Hormonal Changes Affect Skin Ageing

Last updated: 9 August 2026

The hormonal influence on skin health

The relationship between hormones and skin is significant and multifaceted. Skin is the body’s largest endocrine organ, it both responds to circulating hormones and produces its own. Understanding how hormonal fluctuations across the lifespan affect skin ageing is essential for both practitioners and patients seeking to optimise aesthetic outcomes.

Practitioners consider hormonal status as a fundamental factor when designing treatment plans. A treatment protocol that works beautifully for a 35-year-old with stable hormones may need significant modification for a perimenopausal patient experiencing rapid oestrogen decline.

Key hormones and their effects on skin

Oestrogen

Oestrogen is arguably the most important hormone for skin health. Its effects are mediated through oestrogen receptors (ER-alpha and ER-beta) present on fibroblasts, keratinocytes, melanocytes, and sebaceous glands. Research published in the American Journal of Clinical Dermatology (2023) documents oestrogen’s critical roles:

• Collagen synthesis: Oestrogen stimulates type I and type III collagen production. Premenopausal women have approximately 30% more dermal collagen than age-matched men.
• Skin thickness: Oestrogen maintains dermal thickness by supporting fibroblast activity and extracellular matrix production.
• Hydration: Oestrogen promotes glycosaminoglycan (including hyaluronic acid) production, maintaining dermal water content and skin plumpness.
• Elasticity: Oestrogen preserves elastic fibre integrity and supports the production of elastin-associated microfibrils.
• Wound healing: Oestrogen accelerates wound healing by modulating inflammatory responses and promoting re-epithelialisation.
• Sebum regulation: Oestrogen counterbalances androgen-driven sebum production, which adds to pore size and skin texture.

Testosterone and Androgens

Androgens, including testosterone, dihydrotestosterone (DHT), and dehydroepiandrosterone (DHEA), exert significant effects on skin throughout life:

• Stimulate sebaceous gland activity and sebum production
• Influence hair follicle behaviour (promoting facial hair growth, which adds to androgenetic alopecia)
• Support collagen density in men (partially explaining thicker male skin)
• Decline gradually in men from age 30 (approximately 1% per year) and in women from perimenopause

Progesterone

Progesterone influences skin through multiple pathways:

• Increases sebum production during the luteal phase (explaining premenstrual breakouts)
• Has anti-inflammatory properties that can benefit skin healing
• Influences melanin production, which adds to pigmentary changes during pregnancy (melasma)

Cortisol

The “stress hormone” has well-documented detrimental effects on skin when chronically elevated:

• Degrades collagen and elastin through upregulation of matrix metalloproteinases
• Impairs skin barrier function by reducing ceramide and lipid production
• Suppresses immune function, increasing susceptibility to infections
• Increases blood glucose, promoting glycation (cross-linking of collagen with sugar molecules)

Thyroid Hormones

Thyroid hormones (T3 and T4) regulate epidermal turnover, hair growth, and sebaceous gland function. Hypothyroidism causes dry, pale, cool skin with delayed wound healing, whilst hyperthyroidism can cause warm, moist skin with increased pigmentation.

Hormonal milestones and skin ageing

Puberty

The surge in sex hormones during puberty transforms the skin, increasing sebum production, triggering acne in many individuals, and beginning the sex-specific differentiation of skin characteristics. This hormonal surge also supports peak collagen production, establishing the dermal foundation that will be drawn upon in later decades.

The menstrual cycle

Cyclical hormonal fluctuations affect skin on a monthly basis. Research in Skin Research and Technology (2023) used objective measurement tools to demonstrate that skin hydration peaks during the ovulatory phase (high oestrogen), sebum production peaks during the luteal phase (high progesterone), and skin barrier function is weakest during menstruation (lowest oestrogen and progesterone).

Pregnancy

Dramatic hormonal shifts during pregnancy can cause melasma (the “mask of pregnancy” affecting up to 70% of pregnant women), linea nigra and areolar darkening, increased skin sensitivity, and changes in skin texture and oil production. Most pregnancy-related skin changes resolve postpartum, though melasma can persist and may require professional treatment.

Perimenopause and Menopause

This represents the most significant hormonal shift in terms of skin ageing. The rapid decline in oestrogen has dramatic consequences, which have been documented extensively in dermatological literature:

• Collagen loss:
• Skin thickness: Decreases by approximately 1.13% per year after menopause.
• Hydration: Reduced hyaluronic acid and glycosaminoglycan levels lead to increased transepidermal water loss and clinical dryness.
• Elasticity: Elastic fibre degradation accelerates, which adds to skin laxity.
• Healing: Wound healing slows significantly, with important implications for post-procedure recovery times.

Andropause

While less dramatic than female menopause, the gradual decline in testosterone in men from age 30 onwards affects skin quality. Men experience slower collagen loss than women (approximately 1% per year consistently, rather than the rapid post-menopausal decline), but ultimately reach similar endpoints by their 70s and 80s.

Aesthetic implications and treatment modifications

Understanding hormonal influences allows practitioners to tailor aesthetic treatments more effectively:

For perimenopausal and menopausal patients

• Collagen-stimulating treatments become priority: Biostimulators (poly-L-lactic acid, calcium hydroxylapatite), microneedling, and radiofrequency treatments are particularly valuable during this period of accelerated collagen loss.
• Hydration-focused protocols: Skin boosters and hyaluronic acid treatments address the loss of dermal hydration.
• Modified recovery expectations: Slower healing means longer intervals between treatments and more conservative parameters for energy-based devices.
• Skincare adjustments: Richer formulations, barrier-repair ingredients, and phytoestrogen-containing products (topical isoflavones) may support skin during hormonal transition.

For patients with hormonal acne

• Treatment timing around the menstrual cycle can optimise results (peels and microneedling during the follicular phase when skin is less reactive)
• LED blue light therapy can address active breakouts without hormonal disruption
• Niacinamide and azelaic acid help regulate sebum without the photosensitivity risk of retinoids during summer months

For patients on hormone replacement therapy (HRT)

Research published in Maturitas (2023) demonstrates that systemic HRT partially preserves skin collagen and thickness. Patients on HRT often have better baseline skin quality and may respond more robustly to collagen-stimulating treatments. This information helps practitioners set appropriate expectations and design treatment timelines.

Lifestyle strategies for hormonal skin health

Complementary lifestyle measures can support hormonal skin health:

• Phytoestrogen-rich diet: Soy, flaxseed, and legumes contain isoflavones that weakly bind to oestrogen receptors.
• Stress management: Reducing chronic cortisol through meditation, exercise, and adequate sleep protects against cortisol-mediated collagen degradation.
• Regular exercise: Moderate exercise supports healthy hormone balance and improves skin circulation.
• Adequate sleep: Growth hormone release during deep sleep supports tissue repair and collagen synthesis.
• Limiting alcohol and refined sugar: Both promote inflammation and glycation, accelerating hormonal skin ageing.

Key Takeaways

• Hormones fundamentally influence skin structure, function, and ageing trajectory
• Oestrogen decline at menopause causes the most rapid phase of skin ageing
• Treatment plans should be modified based on hormonal status and life stage
• Collagen-stimulating treatments are particularly valuable during periods of hormonal transition
• Lifestyle factors can meaningfully support hormonal skin health
