Even though the terms "oily skin", "dry skin", "combination skin", and "normal skin" are still in use, new classifications are emerging based on criteria other than the level of sebum secreted, thus expanding the list of different skin types. According to a more advanced scientific methodology, we have established not 4 but 24 different skin profiles. So, what does it mean to have DP(.) skin?
What do we mean by having DP(.) skin?
What does having a DP(.) profile imply?
Skin Aging BEGINNER
Oxidation Factor PROTECTED
Sebum Production BALANCED (.)
The letter "D" for Beginner regarding skin aging.
The letter (D) indicates the appearance 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. A change 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 observe the beginning 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 brightness 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 "P" stands 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 aging 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 trigger DNA mutations that eventually lead to the formation of cancerous cells. Thus, even though the skin has some defenses against UV rays (melanogenesis, endogenous antioxidant system...), it is important to regularly and adequately apply 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 effect or "crocodile skin", and its skin texture is regular and uniform with pores 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 regulatory mechanisms.
