NoNot only do we want to clear up any doubts about microflora and the microbiome, but we also explain how important they are to healthy skin and life-changing skincare.
How many times have you heard of microbiome in advertisements skin care or read about some packaging microbiome science and similar words?
“There’s been a lot of talk about the microbiome lately, and it’s one of the biggest innovations we’re facing in medicine,” says Dr. Vera Tengattini, dermatologist and aesthetic physician.
The subject is not simple and it is also quite new, but what we can tell you is that we are also talking about bacteria. Yes, you understand, let’s talk good bacteria which have always been associated with bowel functions – you will surely have heard of it intestinal microbiome in the past – but for some years the issue was fundamental to her skin care and health.
But before we dive into the topic, let’s try to clarify some terms that will be repeated often.
Germ and Microbiome: What’s the Difference?
“Just like the gut, our skin hosts a set of bacteria, fungi and viruses that make up its microbiome,” explains doctor Vera Tengattini.
Much has been said about the benefits of being healthy balance of intestinal microflorabut who knows why, when it comes to skin, bacteria is only seen as something negative.
However, studies in recent years are changing this narrative, proving that It is precisely the balance of these organisms that affects the health of the skin.
“There dysbiosis it is the alteration of this balance that it causes in predisposed subjects skin diseases which are due to the fact that the skin loses its function of integrity,” says the dermatologist.
“Diseases like acne are precisely due to dysbiosis. The Propionibacterium acnes it’s the bacteria responsible for acne and we all have it, but in tiny amounts. However, when it is highly present in the microflora, it secretes lipases, metalloproteases and porphyrins and hyalurondases that degrade hyaluronic acid and cause an inflammatory reaction that produces free radicals and damages keratinocytes, but mainly activates Toll-like receptors. The immune system That alter the skin barrier”, explains Tengattini.
“The study of microflora has changed the approach of medicine to certain types of diseases, so the goal is being achieved non-dysbiosis to keep the microflora intact and healthy.”
“The microbiome is instead of the genetic heritage possessed by the microflora, i.e. the set of genes expressed by the microorganism”.
Skin barrier: what it is and what it is used for
“The skin is the largest organ of the human body and has numerous functions, primarily that of a shield, to protect us from external attacks. That’s why when we talk about skin we say skin barrier“.
“The skin barrier not only prevents us from coming into contact with pathogenic microorganisms, but also protects us from trauma and heat, both in terms of burns and protection from the sun’s rays. The skin also acts as a contact with the external environment. It is thanks to the skin that sweating and perspiration occur and that we maintain a constant body temperature.’
“When we talk about skin care and skin care in general, we refer above all to the skin barrier of the face and it is genetics that determine the type of skin we have“, begins the dermatologist.
“Skin consists of keratinocytes, especially those of the stratum corneum, ceramides, cholesterol and fatty acids. What determines the microflora and therefore the balance of the skin barrier are proteins such as filaggrin, loricrin and cladin, but it has been studied that the type of birth you were born with also affects the microflora, but there are actions we can take to improve it and keep it in balance,” explains Dr. Tengattini.
“The failure to use it sun protection it alters the skin barrier, because the sun damages the skin in the form of drying, increasing the permeability and transpiration of the skin, resulting in drier skin.”
“Also Cleansing is a critical factor for the skin barrier and microflora. Failure to cleanse, poor cleansing, or even too aggressive cleansing causes problems with the skin barrier. In the first cases why are the traces of dirt, pollution and sebum that we produce not removed. in the second because we risk removing the good bacteria found in our microflora and therefore spoiling it.”
“The same applies to exfoliation: when it is excessive – whether it is mechanical or enzymatic – the risk is always that of changeskin balance“.
Prebiotics, probiotics and prebiotics: what they are, what they are for and what’s the difference
“There are many prebiotic sugars used in skin care because they are usually the ones that help respect the balance of skin flora and become the focus of many formulations on the market.”
THE prebiotics they are substances that feed the bacteria and contribute to our well-being. So they strengthen the so-called good bacteria. THE probiotics are living microorganisms that are believed to have a positive effect on the skin. THE prebiotics are metabolic products of bacteria produced through a fermentation process and no longer contain living bacteria.
Skin barrier and hydration
“Skin hydration is measured through instruments that provide specific data, such as the cerasiometer, which also helps to understand whether the barrier function is intact. It is also used to measure the level of skin moisture loss (TEWLor Trans Epidermal Water Loss), another indicator of proper barrier function.
How to protect and maintain the skin barrier
“The ideal is to use detergents that contain softeners. As for day creams for the face, in summer prefer those with a light texture, but which have soothing and anti-inflammatory substances in the formula, fatty acids such as omega 3, 6 and 9, vitamin E, shea butter, thermal waters, panthenol (vitamin B ) and niacinamide’.
