ADULT DERMATOLOGY

Pregnancy & Skin (including Melasma)

Specialist care at Ready Dermatology, North Shore Health Hub, St Leonards

Introduction

Pregnancy involves significant hormonal, immune, and physiological changes, and it is common for the skin to change during this time. Some pre-existing skin conditions may flare, while new skin concerns can develop. Accurate assessment is important to ensure appropriate management while prioritising maternal wellbeing and foetal and infant safety.

When to see a dermatologist

  • New or worsening skin rashes during pregnancy

  • Significant itch, pain, or skin discomfort

  • Pigmentary changes, including melasma, that are spreading or distressing

  • Flares of pre-existing skin conditions such as eczema or acne

  • Uncertainty about the diagnosis or safety of treatments during pregnancy or breastfeeding

  • Concern that a rash may be pregnancy-related or associated with systemic symptoms

Why specialist assessment matters

Skin conditions arising during pregnancy can appear similar but have different implications and management considerations. Some pregnancy-specific skin conditions may mimic other inflammatory or medical disorders.

Dermatological assessment helps clarify the diagnosis, identify conditions that may require closer monitoring, and guide management that balances effectiveness with pregnancy and breastfeeding safety.

Specialist review also helps avoid unnecessary or potentially inappropriate treatments during pregnancy.

Frequently asked questions

  • Pregnancy-related hormonal and immune changes can affect the skin in many ways. These changes may lead to:

    • Increased skin sensitivity

    • Flares of existing inflammatory skin conditions

    • New rashes or pigmentary changes

    • Changes in vascular appearance or skin texture

    The pattern and timing of skin changes often provide important diagnostic clues.

  • Common skin changes and conditions include:

    • Eczema or dermatitis flares

    • Acne or acne-like eruptions

    • Pigmentary changes, including melasma

    • Stretch marks and vascular changes

    While many of these are benign, assessment is important to exclude less common pregnancy-specific dermatoses.

  • Medical review may be helpful to:

    • Confirm the diagnosis of a pregnancy-related skin condition

    • Exclude conditions associated with pregnancy complications

    • Discuss safe management options

    • Clarify expectations regarding resolution after pregnancy

  • Assessment involves a careful history and skin examination, considering:

    • Onset and progression of symptoms

    • Distribution and morphology of the rash or pigmentation

    • Stage of pregnancy or breastfeeding status

    • Medical history and current medications

    Where appropriate, further investigation may be considered to clarify the diagnosis.

  • Management is individualised and guided by:

    • Pregnancy and breastfeeding safety profiles

    • Severity and impact of symptoms

    • The balance of potential risks and benefits

    Care may be coordinated with the GP or obstetrician where appropriate. Patients may also be advised to use MotherSafe, an evidence-based resource, to confirm medication safety during pregnancy and breastfeeding.

  • Melasma is a common pregnancy-associated pigmentation condition. Management focuses on preventing progression and selecting appropriate measures during pregnancy and breastfeeding.

    Sun protection is central to managing melasma. In addition to ultraviolet (UV) radiation, visible light (including blue light) may worsen pigmentation. Physical (mineral) sunscreens, particularly tinted formulations containing iron oxides, are often recommended for pigmentary concerns as they provide broader light protection.

    Treatment is individualised, with attention to pregnancy and breastfeeding status and realistic expectations. Melasma may gradually improve after pregnancy, although ongoing sun protection remains important.

  • Dermatologists are trained to assess skin conditions occurring during pregnancy and distinguish benign changes from conditions requiring closer monitoring. Specialist review supports accurate diagnosis, safe management, and evidence-based guidance tailored to pregnancy and breastfeeding.
