How Hormonal Changes Affect Skin Ageing

Last updated: 9 August 2026

The hormonal blueprint of skin health

Your skin is one of the largest endocrine target organs in the body, densely populated with hormone receptors that respond to fluctuations in oestrogen, progesterone, testosterone, cortisol, thyroid hormones, and growth hormone. Throughout life, hormonal shifts, from puberty through pregnancy, perimenopause, and beyond, leave visible signatures on the skin that influence how we age and how we respond to aesthetic treatments.

Understanding the hormonal dimension of skin ageing is essential for both practitioners and patients. It explains why some individuals age more rapidly during specific life stages, why certain treatments work better at different times, and why a truly effective anti-ageing strategy must account for endocrine health.

Oestrogen: The skin's protector

Oestrogen is arguably the most important hormone for skin health. It influences virtually every aspect of skin structure and function:

• Collagen synthesis: Oestrogen stimulates fibroblast activity and collagen production. Research published in the American Journal of Clinical Dermatology demonstrates that oestrogen directly upregulates type I and type III collagen gene expression.
• Skin thickness: Oestrogen maintains dermal thickness. Skin thickness decreases by approximately 1.13% per year after menopause, a rate that accelerates to 2.1% per year in the first five post-menopausal years.
• Hydration: Oestrogen promotes hyaluronic acid and glycosaminoglycan production, maintaining the skin’s water-binding capacity and plumpness.
• Elasticity: Elastin fibre integrity is oestrogen-dependent. Reduced oestrogen leads to decreased skin elasticity and increased susceptibility to gravitational changes.
• Wound healing: Oestrogen accelerates wound repair, a factor that influences recovery from aesthetic procedures.
• Sebum production: Oestrogen modulates sebaceous gland activity, helping to maintain skin barrier function.

The oestrogen cliff at menopause

The most dramatic hormonal shift affecting skin occurs at menopause, when oestrogen levels decline by approximately 75-80%. Professor Nick Lowe, consultant dermatologist at the Cranley Clinic London, describes this as “the most significant single event in female skin ageing”: “In the first five years after menopause, women lose approximately 30% of their dermal collagen. This is a rate of loss that no topical product alone can fully counteract.”

This collagen cliff explains why many women notice a sudden acceleration in visible ageing around their late 40s to early 50s, it is not gradual decline but a precipitous drop triggered by hormonal change.

Progesterone and Skin

Progesterone plays a more nuanced role in skin health. During the luteal phase of the menstrual cycle (after ovulation), elevated progesterone levels can:

• Increase sebum production, potentially triggering premenstrual breakouts
• Promote water retention, temporarily affecting facial contour
• Support skin barrier function through its influence on ceramide synthesis
• Provide mild anti-inflammatory effects that protect against UV damage

During pregnancy, dramatically elevated progesterone (alongside oestrogen) contributes to the “pregnancy glow” through increased blood flow and oil production, and to melasma (the “mask of pregnancy”) in susceptible individuals.

Testosterone and Androgens

Both men and women produce testosterone, though in different quantities. Androgens influence skin ageing through several mechanisms:

• Sebaceous gland activity: Testosterone drives oil production. This is why male skin tends to be oilier and thicker than female skin, and why men often show signs of ageing slightly later.
• Collagen density: Testosterone maintains collagen density, which is approximately 20% greater in male skin.
• Hair growth patterns: Dihydrotestosterone (DHT) causes androgenetic alopecia in genetically predisposed individuals and drives unwanted facial hair growth in women.
• Acne: Androgen excess or sensitivity is the primary driver of hormonal acne, particularly along the jawline and chin.

Cortisol: The ageing accelerator

Chronic stress elevates cortisol, the body’s primary stress hormone, with significant consequences for skin health:

• Cortisol activates matrix metalloproteinases (MMPs) that break down collagen and elastin
• It impairs the skin barrier by reducing lipid synthesis in the stratum corneum
• Elevated cortisol suppresses immune function, increasing susceptibility to infection and slowing wound healing
• It promotes glycation, the cross-linking of sugar molecules with collagen that makes skin stiff and sallow
• Chronic cortisol elevation has been shown to reduce skin thickness by up to 15% over sustained periods

A 2023 study in Brain, Behavior, and Immunity found that participants with chronically elevated cortisol levels appeared an average of 4.7 years older than their chronological age, as assessed by blinded dermatologists.

Thyroid Hormones

Thyroid dysfunction, affecting approximately 5% of the UK population, has notable dermatological manifestations:

• Hypothyroidism: Dry, coarse, pale skin; hair thinning; brittle nails; slow wound healing; puffiness (particularly periorbital myxoedema)
• Hyperthyroidism: Warm, moist, thin skin; excessive sweating; hair loss; flushing

Undiagnosed thyroid dysfunction can undermine the effectiveness of aesthetic treatments and should be screened for in patients presenting with unexplained skin changes.

Hormonal considerations in aesthetic treatment planning

Understanding a patient’s hormonal status allows practitioners to optimise treatment timing and selection:

Perimenopausal and menopausal patients

• Collagen-stimulating treatments (microneedling, RF microneedling, polynucleotides, biostimulators) become particularly valuable during and after menopause to counteract accelerated collagen loss
• Skin boosters help address hyaluronic acid depletion and dehydration

Patients with hormonal acne

• Addressing the hormonal root cause (often with spironolactone, combined oral contraceptives, or natural anti-androgen supplements) improves treatment outcomes
• Aggressive skin treatments during active hormonal flares risk post-inflammatory hyperpigmentation
• Timing treatments to the follicular phase (days 1-14) of the menstrual cycle may reduce sensitivity and improve healing

Patients on hormonal medications

• Oral contraceptives can increase melasma risk, IPL and laser treatments require careful patient selection
• Testosterone therapy in men may increase sebum production and acne
• Bioidentical hormone therapy requires monitoring for skin changes

A whole-body approach

We recognise that effective aesthetic medicine cannot operate in isolation from hormonal health. Our consultations include questions about menstrual cycle, menopausal status, thyroid function, stress levels, and hormonal medications. When appropriate, the evidence supports hormonal assessment by an endocrinologist or menopause specialist alongside our aesthetic treatment plans.

This integrated approach ensures that treatments are not fighting against hormonal headwinds, but working in concert with the body’s endocrine system for optimal, lasting results.
