The epidermis is made up of a large proportion of water. When this water is lacking, the skin becomes vulnerable. This level of hydration must therefore be restored.
Make-up and sensitive skin do not always go hand in hand. A minor error in the choice of product, and the skin instantly retaliates: redness, irritation, allergic reactions, etc.
Do you hesitate in cleaning your skin every evening for fear of causing irritation?
Beyond that of managing your dermocosmetic arrangements, La Roche-Posay has come to understand the undeniable importance of managing your personal life.
A true epidemic, allergies have continued to increase develop in all countries over ...
"My skin will no longer tolerate anything".
Currently, one in two persons claims to be allergic and/or intolerant.
Atopic eczema or atopic dermatitis is a common skin disorder, which often appears at around the age of three months, but can also develop at an earlier age. To reduce the number of outbreaks, avoid contact with allergens and regularly apply emollient creams.
Daily exposure to external aggressors and irritants weakens the skin on the hands and lips, and this has repercussions.
When the skin is dry, it is more sensitive to external aggressors. As a result, it is irritated, feels tight, and becomes really uncomfortable.
With strong expertise in treating atopic skin, the La Roche-Posay Dermatological Laboratory presents LIPIKAR, a range of products suitable for sensitive, atopy-prone skin. More than just products, this skincare range helps to improve the quality of life not only of children affected by this pathology, but also their families.
The result of a true technological revolution, LIPIKAR Baume AP+ is the latest product in the Lipikar range, the reference range of emollients for very dry and atopy-prone skin for over 25 years.
Currently, more than 20% of children suffer from "atopic" eczema (also known as atopic dermatitis). Usually non-serious, this cutaneous complaint is nonetheless a genuine source of discomfort for children… and parents.
However, this itching and its impact on everyday life can be avoided. Discover a life-changing routine.
When women speak about being concerned by the first signs of aging, the eye contour is mentioned first.
Often intolerant of conventional anti-wrinkle skincare products, sensitive skin is less well prepared for resisting the passage of time. In addition to wrinkles and loss of firmness, it is subject to persistent redness that makes it less uniform. Today, specific treatments have been developed to meet all the anti-aging needs of sensitive skin.

True or False ? >  results
When worn for too long, nail polish can make nails turn yellow
Unless you wear a transparent or treatment base coat. This base coat offers a layer of protection between the nail and the pigments in your varnish. Nevertheless it is still a good idea to let your nails breathe and wear nothing for a few days. Some varnishes have anti-migration pigments to limit yellowing of the nails.
Products for sensitive eyes do not offer optimal results
Thanks to a rigorous selection of ingredients, make-up for sensitive eyes ensures optimal comfort. At the same time, it also delivers an outstanding beauty impact: intense colours for eye shadows, volume and/or length for mascara... and in all cases, the products have impeccable hold and colours that do not fade.
You should always use a moisturising cream before for applying make-up
For a successful, luminous, even and long-lasting make-up result, it is advisable to moisturise the skin, regardless of whether you use a foundation. Moisturised skin also makes it easier to apply make-up and evens the skin's texture.
Make-up prevents the skin from breathing and causes blemishes
Choosing make-up products with a hypoallergenic, purified formula minimises the risk of intolerance and skin sensitivity and ensures maximum comfort for the epidermis. Certain products are even enriched with sebo-regulating zinc to fight the overproduction of sebum.
Lips are dryer in the winter than in the summer
In both summer and winter, lips are confronted with external stress: sun, seawater, dust and chlorine on the one hand and cold, wind and pollution on the other. Unlike the rest of the body, lips have no corneal layer, sebaceous glands or melanin supply to protect them.
Cutting your hair makes it stronger
This is a myth that is widespread, yet absolutely false. Our hair, which is embedded in the hair follicles underneath the scalp’s surface, grows from its roots. Cutting a strand of hair at the surface of the scalp will have no strengthening effect on the hair whatsoever.
Make-up can worsen my skin problems
TRUE and FALSE
Certain ingredients in make-up products can potentially be allergenic. However, there are products that provide high dermatological and ophthalmological tolerance. With these you can avoid dryness and roughness of the epidermis as well as tightness and redness.
Baldness only affects men
Both men and women can lose their hair. However, women experience diffuse hair loss and tend to lose the hair on the top of their head. For men, hair loss may be much more extensive, leaving only a thin crown of hair above the neck and receding temples.
Psoriasis is linked to stress
We are still unsure as to what precisely causes this skin disease. Nevertheless, the link between psoriasis and stress has been clinically proven. In fact, stress can trigger outbreaks of psoriasis in individuals who have a genetic predisposition to the disease.
Dry and sensitive skin treatments are not pleasant to use
A woman who did not get pigmentation marks during her first pregnancy is not at risk for her second pregnancy
All women are at risk for pigmentation marks and pregnancy mask, regardless of whether they had them during their first pregnancy.
Artificial UV tanning sessions let you tan in complete safety
Tanning is the skin's defence mechanism against UVB rays. Yet UV tanning beds diffuse UVA rays in doses higher than those in sunlight: insidious because they are painless, they only provide a superficial tan and encourage the production of free radicals which are responsible for skin ageing and alterations in the cellular system. Therefore UV tanning beds speed up premature skin ageing and increase the risks of developing skin cancer.
If I have a tan, I no longer need any protection
The skin has defense mechanisms to fight the effects of UV rays: it thickens and produces a pigment (melanin) which partially filters UV rays and gives colour to the complexion-- your tan. However, this "natural" protection against the harmful effects of UV rays is superficial because it only partially filters out UV radiation. A tan therefore does not exempt you from using a sun production product.
Sun protection products prevent vitamin D absorption.
UV rays are required to synthesise vitamin D, which is essential in fixing calcium in the bones. In the summer, even if the sky is overcast, brief periods of exposure (15 minutes) twice a week are all it takes to ensure absorption. Therefore, sun protection does not interfere with this process in any way.
Dandruff is caused by a lack of hygiene
Dandruff is caused by the proliferation of microscopic yeast in the scalp, called Malassezia. Harsh hair care products, stress, a poor diet and even wearing a hat for long periods of time may also play a role in the formation of dandruff.
Anti-dark spot products can be dangerous for the skin
TRUE & FALSE
“Whitening” products sold by unauthorised vendors can contain illegal and dangerous substances (hydroquinone, mercury). Anti-dark spot products sold in pharmacies, however, comply with strict formulation standards and are subject to rigorous testing. These are safe.
Vitamin C is a powerful anti-aging active ingredient, perfectly suited to sensitive skin
Some skin types restore better than others
Certain factors can indeed influence the reconstruction of the skin. Skin heals quicker in young people for example. Morevover, smoking, taking certain medicines or even certain nutritional deficiencies, can impair the healing process.
Sebaceous scaly patches appear during times of stress
FALSE (and TRUE)
They do not only appear during times of stress. However, like other factors that lower the immune defences, stress may aggravate the problem.
Light textures do not provide optimal hydration for dry and sensitive skin
It is normal to experience tight, pulling sensations after a shower
Dry skin feels tight, especially after a shower and particularly in regions with hard water. To minimize skin discomfort, we recommend that you use a gentle, soap-free cleanser and shower in lukewarm water.
Tight, pulling sensations are much more frequent during the winter.
Our skin tends to become drier during the cold months. As a result, pickling and tight, pulling sensations are more common during the winter. This is why it is important to effectively moisturise our skin when the temperatures are low. This is particularly true for our hands, which are increasingly exposed to the cold.
Dermocorticoids are recommended for treating itchiness.
Creams that contain corticoids, called dermocorticoids, treat skin lesions as soon as they appear. In a remission phase, intensely moisturising emollient creams help restore the skin barrier and fight against cutaneous dryness.
Men's skin is thicker than that of women.
Men have thicker skin than women, both in the dermis and the epidermis. On average, the skin on men's faces is 22% thicker.
The sun cures acne
The sun is a false friend. In the summer, its slight anti-inflammatory effect temporarily improves the appearance of imperfections. Yet UV rays greatly stimulate sebum production and thicken the skin leading to blocked pores. In the autumn the opposite happens: the imperfections reappear in even greater numbers.
A deterioration in the quality of the complexion is a sign of ageing
Loss of radiance and evenness in the complexion are the first ravages left by time. From the age of 30, melanin, which gives the skin its colour, is more unevenly distributed. The skin’s surface appears dull and uneven. It doesn’t reflect light as well and the complexion looks more uneven.
Retinol can be used on sensitive skin
Dehydrated skin and dry skin mean the same thing
FALSE (and TRUE)
Dehydrated skin is skin that lacks water. Dry skin is skin that is lacking in lipids. However, some dry skins can also lack water and therefore be both dry and dehydrated.
Sensitive skin is allergenic skin
The hyper-reactivity of sensitive skin is not linked to an allergy but to an abnormal excitability of the skin’s nerve endings. It can be of environmental, vascular or contact origin or be linked to an atopic skin.
