What exactly is PP(+) skin?
Skin ageing PRONOUNCED
Oxidation Factor PROTECTED
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 "P" for Protect against oxidation factors.
The letter "P" signifies that the skin is well protected against the sun's UV rays. Beyond these beneficial effects on mood or vitamin D secretion, excessive sun exposure is the main cause of premature skin ageing and the onset of skin cancers. Indeed, UVA rays can cause dermal changes especially in the elastic tissue and UVB rays lead to epidermal damage. Activation of free radicals, alteration of the cell membrane, DNA modification... UV rays act differently within skin cells to generate damage, which can alter the cell's function, cause its death or provoke DNA mutations leading in the long term to the formation of cancerous cells. Thus, even though the skin has some defences against UV rays (melanogenesis, endogenous antioxidant system...), it is important to regularly apply an adequate amount of a sunscreen product suited to one's phototype and sun exposure conditions for reasonable exposure while limiting risks.
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, particularly due to a greasy and shiny appearance under 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 damage, it is less prone to premature ageing.
