Understanding Eczema and Your Skin’s Needs

Eczema (also called atopic dermatitis) is a skin condition that causes dryness, inflammation, and itching. The skin barrier in people with eczema is often more fragile, meaning it loses moisture faster and is more vulnerable to irritants.

One of the simplest ways to support your skin barrier is to use a soap that:

  • Cleans gently without stripping natural oils

  • Is free from harsh chemicals, synthetic fragrances, and SLS/SLES

  • Contains nourishing plant-based oils and butters

  • Maintains skin hydration after washing


What to Avoid in Soap for Eczema

If you have eczema, steer clear of these common irritants:

  • Sodium Lauryl Sulfate (SLS) & Sodium Laureth Sulfate (SLES) – harsh foaming agents that can dry and irritate skin.

  • Synthetic Fragrance Oils – may cause allergic reactions or skin sensitivity.

  • Artificial Dyes – unnecessary colourants that can trigger flare-ups.

  • Alcohol-based Cleansers – can strip away moisture rapidly.


Why Natural Soap Can Help with Eczema

Natural soaps made using the cold process method keep the skin-loving glycerin naturally produced during soap-making. This glycerin acts as a humectant, drawing moisture into the skin and helping to prevent dryness.

Plant-based oils like olive oil, shea butter, and castor oil provide a gentle cleanse while feeding the skin with fatty acids and vitamins. Essential oils such as chamomile, lavender, or calendula can add soothing, anti-inflammatory benefits—although those with highly reactive skin may prefer fragrance-free options.


If you’re looking for a handmade, eco-friendly soap that ticks all the boxes, Dainty Soap Nest’s Fragrance-Free Natural Soap is a perfect choice for eczema-prone skin.

Why it works:

  • Fragrance-free & colour-free – reduces risk of irritation.

  • Made with plant-based oils & butters – gentle, nourishing cleanse.

  • Palm-oil free & vegan – eco-conscious and skin-friendly.

  • No SLS, SLES, or harsh chemicals – only pure, natural ingredients.

This soap is crafted in small batches in the UK, ensuring quality and freshness. Each bar is rich in natural glycerin, helping to lock in moisture and keep skin feeling soft long after you’ve rinsed.

💡 Tip: Pair this with a fragrance-free moisturiser right after washing to help seal in hydration.


How to Use Soap Safely for Eczema

Even the best soap won’t help if it’s overused. To reduce irritation:

  • Use lukewarm, not hot, water when washing.

  • Keep showers short (5–10 minutes).

  • Pat skin dry gently with a soft towel.

  • Moisturise immediately after washing.
