What is the acid mantle of the skin? Functions and tips for keeping it healthy

Find out here what the skin's acid mantle is and why it is so important to take it into account when establishing our daily skin care routine.

Did you know that your skin is the largest organ in your body? In fact, it accounts for between 5% and 10% of our body weight.The thickness varies depending on the area.

For example, you may have noticed that any wound on the face heals much faster than if it had occurred on the legs. This happens because the area of the face is much more vascularised than the lower limbs, so healing becomes faster. 

Despite this, our skin is very sensitive to change, much more so than we think. As soon as we change our diet, the climate we live in or even the water we use to cleanse our face, it alters, causing imperfections due to this very process of adaptation.

This is precisely where the skin's acid mantle comes into play. What is it and what functions does this natural barrier perform? We'll tell you about it below: 

What is the acid mantle of the skin?

The acid mantle of the skin is a film that is found on the surface of our dermis. Our skin has a barrier called the "hydro-lipid barrier"Thus, the acid mantle corresponds to the aqueous medium through which this barrier performs its function: acting as the first line of defence against external aggression.

This aqueous medium has a lot of beneficial bacteria for our skin, it is that film of water that we can sometimes feel when we run our fingers over our forehead or cheeks. It is what gives it firmness, elasticity and keeps it in balance in all its processes. 

Keep in mind that this acid mantle, as the word suggests, has a pHThe face, as well as the other areas of our skin. In the case of the face, its approximate pH is 5.5slightly acidic (considered acidic below a value of 7). 

What does this mean? That with this pH we will have a balanced and well cared for skin, since there will be perfect regulation of water evaporation from the dermis and coexistence of beneficial bacteria. Hence its barrier function, external aggressions are easily combated with a balanced and well cared for pH.

To give you a better understanding of its importance, let's talk about its functions.

Functions of the acid mantle of the skin

The acid mantle of the skin has a number of tasks within the ecosystem of this large organ that enable it to fulfil its purpose efficiently:

  • Thanks to him, ceramides, fatty acids, cholesterol are formed and, in short, the lipids responsible for moisturising the skin and holding the cells of our dermis together.
  • He is also in charge of inducing the skin's desquamation processIs this a good thing? Yes, because peeling means that your body is getting rid of dead cells, which helps the regeneration process of your dermis. As a curiosity, you should know that you lose approximately one and a half kilos of skin per year. 
  • Keeps in balance the micro-organisms that live with us and are beneficial to usThe skin of your face heals faster than other (external) parts of your body. This is one of the reasons why the skin on your face heals faster than other (external) parts of the body.

As you can see, the skin's acid mantle is responsible for protecting the skin, the first line of defence against the outside world. And like all elements that need to be balanced, it is also something that it is very easy to break away from factors such as:

  • make-up;
  • pollution;
  • hormonal changes;
  • dehydration;
  • harmful products, etc.

Another curious fact is that, although the average pH value of the skin is 5.5, it is variable. according to gender and skin type. A man, because he produces more sebum, has a lower pH than a woman. Oily skin also has a lower pH than dry skin. 

That is why it is so important to take proper care of your face and to know at all times what type of skin you have to be able to treat it as it deserves and with an optimal balance. Pimples, redness, irritation or blemishes are nothing more than external elements that have unbalanced our pH.

How to keep the skin's acid mantle in balance?

In fact, if you want your skin to be balanced and your hydro-lipid barrier in perfect condition, you just need to pay attention to certain details:

  • The first thing, beware of products that are too alkalineThese profoundly alter the pH. Alcohol is not bad per sebut in combination with certain soaps or scents it can have an adverse effect to the one we are looking for.
  • Don't exfoliate your skin too hard or too often.. Obviously, it also depends on your skin type (oily skin needs more exfoliation than dry skin), but facial skin is easily broken and vulnerable to external aggressions. If you are going to exfoliate, it should be done with firm circular movements, but without excessive pressure. Once a day (for oily skin) or three times a week for dry skin is enough.
  • Neither cold nor hot water: lukewarm water. Both extremes are excessive, because in the end they burn the skin to some extent. Warm water, on the other hand, is perfect so that your skin does not suffer in the slightest.
  • Don't go to bed without cleansing your skin first.. We are in the habit of washing our face only in the morning and throughout the day we are subjected to factors such as the weather or pollution, as well as certain products such as make-up. If we do not remove them before going to bed, the harmful bacteria we mentioned earlier start to proliferate and the acid mantle becomes unbalanced and loses its barrier function. So: routine cleansing at night and your skin will be radiant the next day.

In our Sam Parfums catalogue we have all kinds of products for the facial care that will allow you to maintain the balance of your skin's acid mantle.
