Retinoids Explained: Myths, Purging, Irritation & How to Use Them Properly

Listen Later

Are retinoids ruining your skin, or transforming it?

From viral misinformation to real clinical evidence, this episode tackles the biggest retinoid myths, like whether they thin your skin or cause inflammation.

Consultant dermatologists Dr Emma Craythorne and Dr Ellie Rashid give you a step-by-step guide to using prescription retinoids safely and effectively.


What You’ll Learn in This Episode:

  • Do retinoids thin the skin? (Spoiler: no. This episode covers what they actually do)
  • The difference between retinol vs prescription retinoids like tretinoin and adapalene
  • Why retinoids are the gold standard for anti-ageing and acne
  • What “retinization” and retinoid dermatitis really looks like

    • How to manage:

    • What purging is (and how long it lasts)
    • Why your skin might react differently in cold UK weather
    • The biggest skincare mistake: combining retinoids with exfoliating acids
    • Why SPF is essential when using retinoids

      • How to Use Retinoids (Dermatologist-Approved Routine)

      A step-by-step approach to minimise irritation:

      1. Apply to dry skin (wait 20–30 minutes after washing)
      2. Avoid sensitive areas (corners of nose, mouth, eyes)
      3. Start slowly and build consistency
      4. Use the “moisturiser sandwich” technique if needed
      5. Try short-contact therapy for sensitive skin
      6. Keep your routine simple—avoid over-exfoliating

        7. Retinoid Side Effects Explained

        Retinoid dermatitis: dry, red, flaky patches (often around nose/mouth)

        Purging: temporary breakouts as skin turnover increases
        Sensitivity changes due to environment, illness, or product changes
