Find the Ideal Soap for Sensitive Skin: Complete Guide and Advice

Having sensitive skin can make the search for the perfect soap complicated. Irritation, tightness when you get out of the shower, dry skin: you need softness and repair!

In this article, find out how to choose the right liquid or solid soap or shower gel for sensitive skin, to soothe, soften and moisturize it.

Hypoallergenic formulation: La Base Essentielle

When looking for the perfect soap for sensitive skin, choose a "hypoallergenic" formulation, free from allergens or potentially irritating ingredients.
These soaps are specially designed to minimize the risk of allergic reactions, offering a gentle, safe option for all skin types.

Fragrance-free: Gentle is better

Strong perfumes can trigger skin irritations. Opt for fragrance-free or lightly scented soaps that are allergen-free.

Soothing Natural Ingredients: Gentle skin nourishment

Look for soaps containing soothing natural ingredients such as plant oils and butters. These components calm irritation, moisturize the skin and promote a gentle cleansing experience.

Dermatologically tested: The guarantee of skin tolerance

Make sure the soap has been dermatologically tested. This guarantees that the product has been assessed by experts for safety and efficacy, offering added reassurance for sensitive skin.

pH Balanced: Soap, syndet, dermatological bar. We explain it all

The pH of our skin is slightly acidic: around 4.7 to 5.75.

A pH-neutral skin cleanser (physiological pH) is one that has the same pH as the skin and therefore respects its natural balance, which is essential for maintaining a healthy skin barrier and helping to prevent irritation and dryness.

But what's the difference between soaps, superfatted soaps and syndets or dermatological loaves? What should you choose?

Here we explain why, while a traditional or superfatted soap is perfectly suitable for more robust skin, a pH-neutral syndet or dermatological bar is the ideal choice for sensitive skin that feels tight after a shower or suffers from discomfort.

- Traditional soaps: An alkaline pH

Traditional soaps are obtained by a saponification reaction (soda + fat). Whether the manufacturing process is cold or hot, and whether noble raw materials or low-cost oils and fats are used, the result is an alkaline product with a higher pH than that of the skin.
Although they cleanse effectively, their frequent use can disrupt the skin's natural pH, potentially leading to skin imbalances, dryness and discomfort.

- Surgras soap: Alkaline pH, but enriched with superfatting agents

A superfatted soap is a type of soap that contains a higher proportion of oils or fats than traditional soaps. Superfatting means that the soap formula contains more oils than are needed to react with the caustic soda during the saponification process. In other words, some of the oils in the soap are not transformed into soap during manufacture, remaining in the final product.

Superfatted soap doesn't respect the skin's physiological pH, but does add moisture.

- Syndets et pains dermatologiques: La Solution Douce with physiological pH

Syndets (liquid or solid forms) and dermatological lotions (solid forms) use foaming agents of various origins and are formulated to have a pH as close as possible to that of the skin. This makes them gentle and less likely to upset the natural balance, especially for sensitive skin.

Natural or synthetic in origin, their formulations vary from one product to another, so you can select the one that suits your particular needs.
