I have PE(+) skin, what does this mean?
PE(+), what does this mean?
Skin Ageing DECLARED
Oxidation Factor OVERVIEW
Sebum Production HIGH (+)
The "P" for Pronounced Signs of Ageing.
The first letter "P" indicates that skin ageing is well established. On mature skin, after the age of fifty, expression lines that appeared earlier (crow's feet at the corners of the eyes, frown lines...) become increasingly pronounced, with loss of firmness being the cause. Cellular degeneration continues, coupled with a reduction in the number and size of fat cells in the fatty tissue of the hypodermis, the deepest layer of the skin. This reduction leads to a loss of volume and firmness, which will hollow out the cheeks.
Furthermore, in women, at the time of menopause, deficiencies in oestrogen and progesterone exacerbate the chronological ageing of the skin. Indeed, oestrogens stimulated keratinocytes, the synthesis of hyaluronic acid and collagen, and inhibited the growth of hair follicles. However, with this abrupt drop in the secretion of female hormones, we observe an increased skin dryness, a modification of the barrier function and a loss of radiance.
The letter "E" for Exposure to oxidation factors.
The "E" indicates that the skin is highly exposed to external aggressions (solar radiation, air pollution, tobacco, stress, thealcohol...), as well as insufficient sun protection habits relative to the phototype and exposure rhythm. These factors promote the production of free radicals, highly unstable and reactive molecules that can have a lasting impact on the skin. However, this action 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 natural ability to neutralise them, oxidative stress sets in and skin damage occurs. Indeed, these reactive oxygen species contribute to the degeneration of skin cells, both at the level of the epidermis and the dermis. All vital components of the skin such as collagen, hyaluronic acid, elastin, lipids and DNA find themselves under attack, thereby causing damage and malfunctions.
This oxidation process can thus affect the structure of the skin, leading to premature skin ageing or even cancer. Initially superficial wrinkles that gradually deepen, less toned skin and a duller complexion can start to appear, even before old age. To slow down their action and thus prevent premature skin ageing, the daily application of antioxidant-based treatments, 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 at all times, 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.
