Natural solid soap for face and body: how to choose the right formula for your skin

A natural solid soap for face and body can simplify your daily routine, reduce packaging, and suit several family members. But the word "natural", a pleasant fragrance, or the promise of soft skin isn't enough to guarantee the right choice.

Some mistakes are particularly common:

  • Confusing natural origin with organic certification: a formula can contain plant-derived ingredients without having an organic label.
  • Choosing a scented soap for the face when the fragrances and allergens listed in the INCI list may be poorly tolerated by reactive skin.
  • Neglecting to dry the soap after use: a soap left sitting in water softens quickly, even if its formulation is impeccable.
  • Relying solely on the term "superfatted": the percentage of added oils or butters, the full ingredient list, and the intended use also deserve your attention.

Criteria to check before buying

1. The INCI list and intended use

The INCI list shows ingredients in descending order of concentration. For a soap intended for the face, look for cleansing agents derived from vegetable oils, glycerine, or vegetable butters. A formula designed for body and hands won't necessarily offer the same comfort on the face.

A vegetable soap can be made from olive, coconut, palm, or other oils. The presence of a plant-based ingredient doesn't automatically mean the product is vegan. If this matters to you, also check for the absence of animal-derived ingredients and the information provided by the brand.

To choose an organic soap, look for a clearly displayed label on the packaging or product page. The mere presence of vegetable oils or botanical extracts isn't enough to establish certification.

2. Lipid richness and skin type

A superfatted soap contains a proportion of fats that haven't been transformed during saponification, depending on the process used and the formulation. Shea butter, as well as sweet almond, jojoba, or hemp oils, are often associated with a more comfortable feeling after rinsing.

For dry or sensitive skin, choose a clear formula and avoid piling on exfoliating or heavily fragranced products. A rich formula doesn't rule out an individual reaction: test the product on a small area first and stop using it at the first sign of discomfort.

3. Usage, fragrance, and storage

An exfoliating soap containing plant particles, rice powder, clay, or charcoal shouldn't be used as often on the face as on the body. The Pelican soap, for example, contains more exfoliating particles than its classic version and recommends use on the hips, thighs, and body.

To preserve a hydrating solid soap, rinse it after use and place it on a slotted soap dish away from the direct stream of water. This simple habit reduces wastage and helps a 80 g or 100 g bar last longer. Also remember to check the best-before date, batch number, and usage precautions.

Frequently asked questions about natural solid soap

Can a solid soap be used on both face and body?

Yes, provided the product page indicates both uses and your skin tolerates it. A facial soap is generally chosen for its gentler lather and formula enriched with oils or butters. For the body, scented or exfoliating versions can work, as long as you follow the usage recommendations.

How long can you keep a solid soap after opening?

It depends on how often you use it, the weight of the bar, and how well it dries. After each wash, rinse it, shake off the excess water, and place it on a slotted surface. Check the date and batch number printed on the packaging, especially if it's a French artisanal soap or a product containing plant-based ingredients that may vary slightly in colour or fragrance.

Is a superfatted soap suitable for all skin types?

A superfatted soap can provide a feeling of comfort for dry skin, but it isn't necessarily right for everyone. Tolerance depends on the composition, fragrance, frequency of washing, and the area being washed. If your skin is sensitive, start with spaced-out uses, avoid the eye area, and stop immediately if irritation occurs.
