Although traditionally there are four types of skin, at Typology, we have developed a scientific methodology based on three universal criteria, thus revealing 24 skin typologies. In this article, we will discuss in more detail about the AE(+) skin. What does this mean?

What lies behind the initials AE(+) ?
Skin ageing ABSENT
Oxidation Factor OVERVIEW
Sebum Production HIGH (+)
The letter "A" for Absence of signs of ageing.
The letter "A" signifies thatno signs of ageing are visible on the skin. Indeed, three main manifestations can affect the appearance of the face, namely wrinkles, a skin sagging (loss of volume) and loss of density. Generally, the first signs of skin ageing appear around the age of 25, reflecting the changes that occur in the different layers of the skin (slowing of cell renewal, reduction in lipid production, decline in the production of collagen, elastin and hyaluronic acid, decrease in the size and number of fat cells...). Although ageing is an inevitable process, it is possible to prevent and exert some control over the various factors affecting the speed of ageing, and thus delay the onset of ageing signs.
The letter "E" for Exposure to oxidation factors.
The second letter (E) defines the level of exposure and protection of the skin against the multitude of aggressions throughout the day, such as solar radiation, atmospheric pollution, tobacco, stress, thealcohol, etc. Indeed, these external sources generate free radicals, unstable and highly reactive molecules that can have a lasting impact on the skin. However, this biochemical reaction is normal in all living organisms that consume oxygen.
However, in the event of an imbalance between the production of free radicals and the body's ability to naturally eliminate them, oxidative stress sets in and problems arise. Indeed, these reactive forms of oxygen contribute to the degeneration of skin cells, both at the level of the epidermis and the dermis. All the essential constituents of the skin (collagen, hyaluronic acid, elastin, lipids, DNA) find themselves under attack, thereby inducing damage and dysfunctions.
Cellular oxidation can thus affect the structure of the skin, causing a speeding up of the skin ageing process or a cancer. Visible signs of ageing may start to appear such as initially superficial wrinkles that become increasingly deep, less toned skin and a duller complexion, and this can occur prematurely. To curb their action and thus prevent premature skin ageing, the daily application of antioxidant-based treatments (vitamin C, ferulic acid, resveratrol...), in addition to an appropriate sun protection , is recommended.
The symbol "+" for high sebum production.
The AE(+) skin type is characterised by a production of sebum that is naturally high (hyperseborrhoea). This excessive secretion is primarily physiological, determined by hormonal activity, although it is also influenced by environmental factors (body temperature, circadian rhythm, intake of certain medications, diet rich in fats and sugars, stress...). Although this skin type is well protected by a lipid-rich hydrolipidic film that covers the entire skin surface, this imbalance in sebum production can be a source of concern, with a greasy and shiny appearance in all circumstances, an increased risk of developing spots and blackheads, an enlargement of the pores, an irregular skin texture due to imperfections that create a micro-relief, and a dull complexion due to poor light reflection. However, being thicker and more resistant to aggressions, it is less prone to premature ageing.
Be cautious if you are AE(+), as being daily exposed to external factors without real protection, could increase the secretion of sebum and also contribute to accelerating the appearance of ageing signs.
