In Episode 18 of The Lifestyle Prescription with Pharmacy Planet, host Rena Dipti Annobil is joined by Dr Mandy Leonhardt (DRCOG MRCGP DFFP), a GP and women’s health specialist, for a powerful and evidence-based conversation on perimenopause, hormone health, skin ageing, and overall wellbeing.

Perimenopause is a stage that affects every woman — yet many feel unprepared for the physical and emotional changes that come with it. From dry skin, acne, hair thinning and brain fog to mood changes and sleep disruption, symptoms are often misunderstood or dismissed.

In this episode, Dr Mandy explains how hormonal imbalances affect the skin, hair, brain and body, and shares practical, evidence-based advice on HRT, skincare, lifestyle changes and healthy ageing.

Whether you’re navigating perimenopause symptoms, exploring HRT options, or simply want clarity on women’s health and hormone balance, this episode offers trusted guidance grounded in medical expertise.

Why Women’s Hormonal Health Is Still Misunderstood

Despite affecting millions of women in the UK, perimenopause and menopause remain under-discussed in mainstream healthcare.

Dr Mandy explains that medical training often focuses on reproduction — not long-term hormonal health. As a result, many women are left searching for answers about symptoms like:

  • Brain fog
  • Mood changes
  • Skin issues
  • Hormonal acne
  • Sleep disruption

This lack of awareness contributes to delays in diagnosis and treatment — particularly in areas like menopause care, HRT access, and women’s health support in the UK.

How Hormones Affect Skin Ageing

Hormones play a central role in skin health and ageing.

Key hormones include:

  • Estrogen – maintains hydration, elasticity and collagen
  • Testosterone – regulates oil production
  • Cortisol – impacts inflammation and stress response

As Dr Mandy explains, the skin itself is an endocrine organ — meaning it both produces and responds to hormones.

When these hormones fluctuate, particularly during perimenopause, the effects become visible in the skin.

Perimenopause Skin Changes Explained

During perimenopause, estrogen levels fluctuate and gradually decline, leading to common symptoms such as:

  • Dry, itchy or sensitive skin
  • Increased skin reactivity
  • Hormonal acne (especially around the jawline)
  • Rosacea and redness
  • Uneven skin tone and pigmentation

Many women also notice that skincare products they’ve used for years suddenly stop working — or begin causing irritation.

Hair Loss, Stress & Iron Deficiency

Hair thinning is one of the most common — and distressing — symptoms of perimenopause.

Dr Mandy highlights that iron deficiency is a leading cause, particularly in women with heavy periods or post-pregnancy depletion.

Stress also plays a major role. Elevated cortisol levels, combined with lifestyle pressures, can trigger telogen effluvium — a form of temporary hair shedding.

Brain Fog & Sleep Disruption

Many women worry that brain fog may be something serious — but in most cases, it’s linked to poor sleep quality.

Symptoms include:

  • Forgetfulness
  • Difficulty concentrating
  • Word-finding issues

Sleep disruption is one of the biggest drivers of cognitive symptoms in perimenopause.

Improving sleep can significantly improve mental clarity, energy levels and overall wellbeing.

Anhedonia & Mental Health in Perimenopause

One lesser-known symptom is anhedonia — the loss of enjoyment in activities that once felt pleasurable.

This is often mistaken for depression, but it can present differently:

  • Feeling disconnected
  • “Going through the motions” socially
  • Struggling to feel joy

Dr Mandy emphasises the importance of emotional health, boundaries, and reducing mental load during this stage of life.

HRT Explained: Benefits, Risks & Myths

Hormone Replacement Therapy (HRT) is one of the most effective treatments for menopause and perimenopause symptoms.

Benefits may include:

However, HRT is not suitable for everyone — particularly those with certain hormone-sensitive cancers.

Dr Mandy also clarifies the confusion around:

  • Bioidentical vs body-identical hormones
  • NHS vs private HRT options
  • Topical estrogen vs systemic HRT

The key message: HRT should be individualised and evidence-based.

Collagen Loss & Skin Ageing Truths

One of the most important insights from this episode:

  • Women lose up to 30% of collagen in the first five years after menopause

This contributes to:

  • Fine lines and wrinkles
  • Loss of skin elasticity
  • Thinner, drier skin

While skincare can support skin health, collagen loss cannot be fully reversed — making early intervention and prevention key.

Skincare Trends: What Works & What Doesn’t

From collagen supplements to LED face masks, the skincare industry is full of trends — but not all are backed by evidence.

Dr Mandy’s perspective:

  • Collagen powders: limited evidence, often poor value
  • LED masks: minimal proven benefit
  • Expensive skincare: often similar formulations to cheaper products

The takeaway: focus on evidence-based skincare, not marketing.

The Best Skincare Routine for Perimenopause

A simple, effective routine includes:

Morning

  • Gentle cleanse (or water only)
  • SPF 50 daily

Evening

  • Cleanse (remove makeup/SPF)
  • Optional exfoliation (e.g. glycolic acid)
  • Moisturiser (look for ceramides or niacinamide)
  • Optional: Vaseline to lock in moisture

Consistency matters more than complexity — and more than cost.

Lifestyle Changes to Support Hormone Health

When it comes to healthy ageing and hormone balance, lifestyle plays a major role.

Dr Mandy highlights:

  • Sleep qua
  • Stress management
  • Nutrition (especially protein and micronutrients)
  • Reducing alcohol intake

One of the biggest contributors to visible ageing?

Sun exposure — not hormones

Daily SPF is one of the most effective anti-ageing habits.

Dr Mandy’s Lifestyle Prescription

Dr Mandy’s top three recommendations:

  • Use SPF daily
  • Minimise alcohol consumption
  • Prioritise restorative sleep

Simple, practical, and evidence-based.
