Why Dermatologists Recommend Castile Soap for Sensitive Skin

If you have sensitive skin, you know the struggle, redness, itching, dryness and irritation often follow after using the wrong product.

That’s why dermatologists frequently recommend Castile soap as a gentle, safe and natural cleanser.

But what makes Castile soap so special? Why is it trusted by skin professionals? In this blog, we’ll explore why dermatologists recommend Castile soap for sensitive skin, its ingredients, benefits, and how to choose the right one for your routine.

What Is Castile Soap?

Castile soap is a plant based, biodegradable soap originally made from 100% olive oil in the Castile region of Spain. Today, it often includes a blend of olive oil, coconut oil, hemp oil, or other vegetable oils, but it remains free from synthetic detergents, animal fats and harsh chemicals.

Common Characteristics of Castile Soap:

-100% plant-based

- No artificial fragrances or preservatives

- Biodegradable and eco-friendly

- Often vegan and cruelty-free

- Can be used on skin, hair, household surfaces, and even pets!

Why Dermatologists Recommend Castile Soap for Sensitive Skin

1. Free from Harsh Chemicals

Many commercial soaps contain:

- Sodium lauryl sulfate (SLS)

- Parabens

- Artificial fragrances

- Alcohol

- Dyes and preservatives

These ingredients are known irritants for sensitive skin. Castile soap avoids all of these, offering a clean, simple formula that reduces the risk of irritation and allergic reactions.

 

2.  Gentle, Non-Stripping Formula

Unlike many soaps that strip away your skin’s natural oils, Castile soap:

- Maintains the skin's moisture barrier

- Cleanses without overdrying

- Leaves the skin feeling soft and balanced

This is crucial for those with eczema, psoriasis, or other sensitive skin conditions.

3. Dermatologist-Backed Simplicity

Dermatologists often recommend minimalist skincare routines for sensitive skin. Fewer ingredients = fewer chances of a bad reaction.

Castile soap often contains fewer than 10 recognizable ingredients, most of which are natural oils and alkali (e.g., potassium hydroxide) used for saponification.

Tip from Dermatologists: Avoid heavily scented or colored soaps if you have sensitive skin. Always patch-test new products!

4. Environmentally Friendly

Sensitive skin often goes hand-in-hand with a sensitivity to the environment. Castile soap is:

- Biodegradable

- Non-toxic

- Comes in sustainable packaging (often recyclable or refillable)

Dermatologists who promote holistic wellness often favor brands that are good for both your skin and the planet.

 Who Should Use Castile Soap?

Castile soap is ideal for:

- People with eczema, dermatitis, or rosacea

- Those with fragrance allergies

- Babies and children with delicate skin

- Anyone undergoing dermatological treatments (e.g., Retin-A, Accutane, laser therapy)

- Individuals following a clean or organic lifestyle

How to Use Castile Soap for Sensitive Skin

Castile soap is highly concentrated, so a little goes a long way.

 For Face & Body:

- Dilute with water (1:2 or more)

- Apply gently using clean hands or a soft washcloth

- Rinse thoroughly with lukewarm water

 For Babies:

- Use an unscented, diluted formula

- Patch test on a small area first

For Handwashing:

- Add a few drops to a foaming soap dispenser with water

- Shake before use

Castile Soap: Potential Considerations for Sensitive Skin

While Castile soap is generally safe, here are a few things to keep in mind:

1. High pH

Castile soap has a natural pH of ~9, while healthy skin prefers a pH of 4.5–5.5. Most people tolerate this well, but if you notice dryness, try:

- Diluting further

- Following with a pH-balancing toner or moisturizer

 

2. Essential Oils

Many Castile soaps are scented with essential oils like lavender or peppermint. While natural, some essential oils can still trigger reactions.

Best for Sensitive Skin: Look for unscented or baby formulas (e.g., Dr. Bronner’s Unscented Baby Mild or Yein&Young Organic Castile Soap).

Morning:

1. Cleanse: Gentle wash with diluted unscented Castile soap
   

2. Tone (optional): Alcohol-free toner
   

3. Moisturize: Fragrance-free, non-comedogenic moisturizer
