Dry, normal or oily, sensitive skin is skin that is physiologically or mechanically weakened. It is therefore easily irritated, having a low reaction threshold to an external stimulus.
The main ingredients that are aggressive for the skin are:
– certain surfactants or cleansing agents: in fact, due to their dual polarity, they can damage the hydrolipidic film. Without protection, the skin becomes more sensitive to aggressions. The “surgras” agents contained in certain cleansers restore the damaged hydrolipidic film.
– fragrances, colourants, preservatives and some excipients can also cause reactions, either irritation or allergies. As regards fragrances, we formulate our products using specific fragrances selected to limit the risk of intolerance.
They can pose two risks to the skin
– irritant reactions
These reactions may occur when the products contain harsh surfactants which damage the hydrolipidic film. This is why it is important to use suitable, well-formulated and preferably surgras cleansers to prevent this type of irritation. In addition, one to two showers a day is ample. In fact, washing yourself too often can unbalance the skin’s protective flora.

– allergic reactions
Like any product applied on the skin, cleansers can cause allergic reactions. It is therefore important when developing a new product to avoid using any ingredient that is a known allergen, such as certain fragrances, preservatives and colourants, and to ensure clinical tests are conducted to confirm the product’s hypoallergenicity.
“Syndets” or “dermatological bars” are soap-free cleansing bars comprised mainly of gentle synthetic surfactants. Their use is justified on the face or body when soap is poorly tolerated or in the case of certain skin conditions. Soaps are produced by means of a saponification reaction, where a mixture of fats (commonly called triglyceride fatty acids) are treated with a strong base. They are more detersive. “Superfatted” soaps are enriched with lanolin, sweet almond oil and glycerine to restore the hydrolipidic film.
From a chemical perspective, the dirt that deposits on the skin is closer to oil than water. Water alone is therefore not enough. Only cleansers are capable of lifting the dirt from the skin, which can then be removed by rinsing with water.
Rogé Cavaillès, the body care expert, continuously innovates to care for and protect the delicate and sensitive skin of the whole family, based on its renowned formulation: the addition of suitable “surgras” agents.
Our skin benefits from a natural protective layer called the hydrolipidic film, which protects the skin in several ways:
• It helps form the cutaneous barrier, shielding against external aggressions.
• It keeps the skin hydrated and supple by retaining moisture.
• It fights germs by protecting the skin’s beneficial flora.
The effectiveness of surgras agents
Hard water, temperature changes and the use of drying treatments and overly harsh cleansers can damage this film. The skin can then no longer serve as a protective barrier: it loses moisture, becomes dry, and is no longer supple.
Surgras agents form a special bond with the skin that prevents them from being rinsed off, leaving a protective layer on the skin.
Benefits to sensitive skin
Improved natural protection against external aggressions.
• Optimal hydration.
Your baby’s skin is different to that of an adult. It is therefore important to wash it with a specific product which has:
– a very gentle cleansing base.
– a light fragrance.
– no colourant.
– surgras agents which will help protect your baby’s skin.
Specific products have proven their very high tolerance on babies’ skin, making them completely safe to use.
If you’re suffering from a fungal infection, consult a doctor. At the same time, wash your underwear thoroughly at 60°C to destroy the fungi. Also, use a specific intimate hygiene product with an alkaline pH, which will help calm the irritation and itching associated with the infection.
The most common fungus is Candida Albicans. This is why fungal infections are also referred to as candidiasis. And again, it all boils down to whether the vaginal ecosystem is balanced or unbalanced. All it takes is a course of antibiotics, an unsuitable hygiene product or sometimes poorly-controlled diabetes, and the fungi start to grow. 70% of cases of candidiasis (thrush), or fungal infection are due to internal causes: an imbalance of the vaginal flora.
Excessive intimate hygiene with an unsuitable cleanser weakens the mucous membranes. The vulvovaginal flora then changes and no longer performs its defensive role, allowing the growth of certain microbes which are responsible for causing unpleasant local irritation. To preserve the flora’s natural balance, there is no need to wash the area more than once or twice a day.
– Avoid clothes that are too tight-fitting between the legs, plastic-coated sanitary towels and panty liners which increase the likelihood of maceration.
– Choose cotton rather than synthetic underwear.
– Change your underwear daily.
– Do not irritate your mucous membranes by using an unsuitable hygiene product.
– If you are sensitive to vulvar itching or irritations, consider switching the laundry powder you use to wash your underwear for a hypoallergenic one.
– Avoid the local use of fragrances (scented toilet paper, intimate deodorants or eau de toilette), which are unsuitable and potential irritants for your skin and mucous membranes.
The main thing is to avoid maceration. Whether you prefer tampons or sanitary towels, you should change them at least every four hours. If you leave the blood and secretions to stagnate for too long, they can become a breeding ground and encourage proliferation of a bacteria called Gardnerella.
To maintain healthy vulvovaginal flora, the pH must be kept at a certain leval of acidity (pH 5.5). It is therefore important to use products with a physiological pH (5.5) that enables the lactobacilli (or Döderlein bacilli) to grow properly and prevent the proliferation of pathogenic bacteria. It is equally important to use a product with a very gentle cleansing base which does not attack the mucous membranes and preferably one that is also hypoallergenic.
The Döderlein bacillus (or Lactobacillus) can secrete certain substances such as hydrogen peroxide (H2O2) and lactic acid, which protect against infections. In fact, these two substances prevent the proliferation of pathogenic bacteria. They also help maintain the vagina’s correct level of acidity, which is between pH 3.8 and 4.5. If for any reason the Döderlein bacilli are destroyed or their numbers drop to an insufficient level (after taking antibiotics or with inappropriate hygiene, for example), then the other vaginal bacteria start to grow and this imbalance causes an infection. The best form of protection of this fragile ecosystem is to wash the intimate area with a suitable product that has a soap-free gentle cleansing base and a physiological pH.
The vulvovaginal flora is an ecosystem that needs to be protected. It is composed of a community of protective bacteria. When all is well, all of these protective bacteria live together in harmony. In fact, when girls are born, their vagina is colonised by a beneficial bacterial flora. During puberty, the vaginal secretions increase and the flora changes to become that of a woman. The most important bacteria is called Döderlein bacillus, also called lactobacillus.
