Sweating is a natural mechanism that regulates body temperature. However, in some cases, it can become excessive. How can you tell if your perspiration is excessive? Let’s take a closer look together.

Perspiration is a natural mechanism that is essential for regulating the body’s temperature. However, when it becomes excessive, it can be disruptive in everyday life. How can this phenomenon be limited without disturbing the skin’s balance? This article explores several approaches to reducing perspiration.

In winter or during the intense heat of summer, on public transport or in the street, under a jumper or in lighter clothing, everyone sweats. Sweat does not necessarily smell unpleasant. However, its odour can be disagreeable in some individuals. What is the cause of this? Discover some answers here.

Facial sweating can quickly become troublesome in daily life, even though it is a natural phenomenon. Why do some people sweat more from the face than others? How can facial perspiration be reduced? Learn more in this article.

Although night sweats are quite common, their origin and causes are poorly understood. Why does the body sweat more during the night? When should night sweats become a cause for concern? And above all, what can be done to reduce them? Read on to find out more about nocturnal sweating.

Perspiring is often perceived as an everyday inconvenience. Yet this phenomenon is essential for the proper functioning of the body. Why exactly do we sweat? Let us examine this process and its causes.

The skin continuously loses water, even when we are not perspiring. This natural phenomenon, known as transepidermal water loss (TEWL), contributes to the skin’s equilibrium. When it intensifies, the skin becomes more fragile and more reactive. But what exactly is transepidermal water loss? Let us explore this mechanism together to better understand skin hydration.

Parabens, UV filters and phthalates: these names often recur when discussing endocrine disruptors. While some have been restricted or banned, others remain authorised under certain conditions. Between suspicion and evidence, it is not always easy to see clearly. What should we know about endocrine disruptors in cosmetics and their potential dangers? Let us explore this topic together.

The skin is not supported solely by collagen and elastin. Other extracellular matrix proteins, such as fibronectin, play an important role in the three-dimensional organisation of skin tissue. As a true interface between cells and their environment, fibronectin contributes to dermal dynamics. How does this protein influence the physiology and appearance of the skin? Let us take a closer look at fibronectin.

Melanoma is one of the most aggressive skin cancers, notably because it can exploit its microenvironment to proliferate and withstand treatments. A team of researchers has shed light on previously unknown mechanisms by which these cells adapt to tissue rigidity. But how does this adaptive capacity influence the evolution of the cancer? Let us explore the details of this scientific advance together.

Free radicals are highly reactive molecules capable of damaging the skin’s cellular components, thereby accelerating skin ageing. Fortunately, our body has a natural antioxidant system responsible for neutralising them. How does this defence mechanism operate? And what role do antioxidants play in protecting the skin? Find out in the rest of this article.

Oxidative stress is often cited as one of the skin’s greatest enemies, yet how it operates remains little known. What happens inside our cells when free radicals take over? Here, discover what oxidative stress actually is, its impacts and the ways to curb it.

The skin is a living ecosystem populated by bacteria, fungi and yeasts. These micro-organisms have a beneficial effect on the skin by strengthening its barrier function and limiting inflammation. However, the balance of the skin microbiome can be disrupted by various factors such as stress, UV radiation or pollution. How can the skin microbiome be preserved on a daily basis? Find all our recommendations here.

Fungi, bacteria, yeasts… our skin harbours a complex flora that acts as a natural shield, yet its balance is fragile. How does the cutaneous microbiota function and what role does it play? What should you do if it becomes disrupted? Read on to discover everything you need to know about the skin microbiota.

If your skin has been unusually sensitive, dry or irritated, you should take the time to assess its defensive strength. The barrier shields your skin from environmental stress, but when compromised it can cause considerable problems. The good news is that damage to this layer of skin can be repaired if the correct approach is taken. Let us see how you can restore this defence system and return it to a healthy state.

The skin is continuously renewed by the division of epidermal cells. However, with advancing age, this process becomes less efficient. What is the relationship between cellular renewal and skin ageing? Discover more about this subject below.

The skin serves as a living interface between our body and the environment. It protects, regulates, and constantly communicates with our cells. But do you truly understand the full extent of its functions? Discover here the various roles of the skin and how it safeguards the body’s equilibrium.

Skin is far more than a mere covering: it is a complex organ that protects, regulates and communicates with our environment. Its three layers – the epidermis, dermis and hypodermis – fulfil complementary and essential functions. How do they interact to maintain skin homeostasis? Continue reading to gain a clearer understanding of skin structure.

Everyone’s skin reacts differently to sun exposure, and these differences are not accidental. The Fitzpatrick classification categorises skin types according to their sensitivity to ultraviolet radiation. How was this scale established, and how is it used today? Discover in this article everything you need to know about the Fitzpatrick classification.

The skin barrier is one of the most fascinating and vital components of your body. It is often taken for granted until something goes wrong. What is this powerful shield that protects us from the rigours of the outside world while keeping us intact? Let’s take a closer look at what makes this barrier so important.

Often associated with sebum production and oily skin issues, the sebaceous glands are, however, more complex than commonly believed. What are their physiological characteristics? How do they interact with the skin? Let us explore together the various facets of the sebaceous glands.

While sunlight is essential to synthesise vitamin D, it can damage the skin after surgery. What risks arise from sun exposure following an operation? Read on to learn why sun exposure after surgery is not recommended.

Despite progress in oncology, some cancers remain resistant to chemotherapy, radiotherapy, and immunotherapy. This impasse prompts researchers to seek alternative approaches. A recent discovery concerns a molecule that induces an atypical form of cell death, ferroptosis, by exploiting an unexpected iron dependency in cancer cells. What is this new treatment strategy and how might it be applied? We will explore these questions.

Menopause is an unavoidable stage in women’s lives. It can cause fatigue, hot flushes, sleep disturbances, and increased skin laxity. Could it be delayed? One compound is drawing attention: rapamycin. First studied for its effect on lifespan, it may also postpone the onset of menopause. Discover the latest scientific advances on this topic.

The production of collagen, a protein crucial for skin elasticity and firmness, has long been considered primarily linked to the activity of fibroblasts. However, a study recently published in Nature Communications suggests that keratinocytes could play a significant role in collagen synthesis. This raises the following question: should pro-collagen cosmetics target keratinocytes instead? Let's explore this question together.
