What are the characteristics of DE(+) skin?

Skin is not solely defined by its sebum secretion. Other factors must be taken into account in order to best adapt one's skincare routine to the needs of the skin. Based on this observation, we have identified 24 skin typologies, including the DE(+) profile. Let's explore in this article what lies behind these initials.

I have DE(+) skin, what do these initials mean?

Skin Aging BEGINNER

Oxidation Factor OVERVIEW

Sebum Production HIGH (+)

The letter "D" for Beginner regarding skin aging.

The letter (D) indicates the emergence of the first visible signs of aging when the skin is in motion . Fine lines are the first to appear and are the easiest to spot. They are typically located at the outer corners of the eyes. Changes in skin texture or a lack of radiance can also be observed. These are generally visible around the age of 25. Indeed, from this age, we see the start of a decline of about 1% each year in the production of collagen, one of the structural components of the skin, leading to a disorganization of the skin's connective tissue and a change in skin elasticity. A slowdown in the renewal of epidermal cells has also been noted, gradually leading to a thinning of the skin's barrier function. As a result of this phenomenon, water evaporates more and more: the skin then loses its luminosity and wrinkles become more pronounced. A decrease in the production of hyaluronic acid by an average of 6% per decade adds to this.

The letter "E" for Exposure to oxidation factors.

The second letter (E) defines the level of exposure and protection of the skin against a multitude of aggressors throughout the day, such as solar radiation, atmospheric pollution, tobacco, stress, alcohol, 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 aging process or a cancer. Visible signs of aging can start to appear such as wrinkles that are initially superficial but become increasingly deep, less toned skin, and a duller complexion, and this can occur prematurely. To curb their action and thus prevent premature skin aging, 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 characterized by a production of sebum that is naturally high (hyperseborrhea). 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 under all circumstances, an increased risk of developing pimples 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 aging.
