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 point "." for Balanced Sebum Secretion.
The "." indicates a balance in sebum production. Naturally produced by the sebaceous glands, the sebum is a fatty substance that helps the skin protect itself against external aggressions and fight against dryness by contributing to the composition of the hydrolipidic film. Comfortable and soft to the touch, this skin type has a matte appearance without a shiny or "crocodile skin" effect, and its skin texture is regular and uniform with pores that are tightened. It is naturally well hydrated, protected, and blemishes are rare. However, despite this skin balance, it also requires specific care to maintain its abilities and strengthen its regulation mechanisms.
