The Meaning of the VE(-) Skin Profile.

Skin Aging VISIBLE

Oxidation Factor OVERVIEW

Sebum Production LOW(-)

The "V" for Visible signs of aging.

The letter "V" indicates that the signs of aging have become visible and are becoming more frequent. Indeed, the small wrinkles at the corners of the mouth and at the corners of the eyes deepen with age, becoming more and more defined, meaning they are now visible both in motion and at rest. Additionally, new folds appear on new areas of the face such as the wrinkles between the eyebrows (frown lines) or the horizontal forehead wrinkles, depending on individual expressions. Apart from wrinkles, the complexion is uneven with pigmentation defects. These various marks that appear on the surface are the result of different changes that occur within all layers of the skin over the years.

A slowdown in the rate of keratinocyte renewal and a decrease in the adhesion of corneocytes are observed starting in our thirties, which impairs the skin's barrier function, making the epidermis more vulnerable to external aggressions, particularly UV rays. Aging is also marked by a decrease of 8 to 10% every 10 years in the cells that produce melanin, a pigment that protects against UV radiation, along with changes in their morphology and distribution, which results in irregular pigmentation on the skin's surface and the appearance of age spots. At the dermis level, the fibroblasts that synthesize collagen, hyaluronic acid, and elastin undergo changes in their morphology and activity, leading to a decrease in the production of essential proteins for skin firmness and elasticity. These phenomena result in the formation of wrinkles.

The letter "E" for Exposing 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 neutralize 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 aging or even cancer. Initially superficial wrinkles that gradually deepen, less firm skin, and a duller complexion can start to appear, even before aging. To slow down their action and thus prevent premature skin aging, the daily application of antioxidant-based treatments, in addition to an appropriate sun protection , is recommended.

The symbol "-" for Low Sebum Production.

The "-" indicates a decrease in the efficiency of the sebaceous glands to produce enough sebum (sebaceous hyposecretion), as well as a discrepancy in the synthesis of natural moisturizing factors by keratinocytes, which give the skin the ability to retain water. Tightness, irritation, dehydration fine lines, redness, flaking, dull complexion... are characteristic of this skin type.

Indeed, this lack of lipids reduces the effectiveness of the hydrolipidic film. The skin then becomes vulnerable to all forms of aggression (UV rays, pollution, bacteria, etc.), triggering inflammatory responses, and no longer effectively prevents transepidermal water evaporation. Additionally, this alteration in the barrier function leads to a dysregulation of Langerhans cells (cells of the immune system), which begin to induce disproportionate inflammatory responses when they are overly stimulated.

Several factors can influence this low sebum secretion, leading to these disturbances: frequent washing, certain medications, inappropriate care, seasonal variations, tobacco, UV radiation, genetics... However, although this skin type is more prone to wrinkle formation due to its less flexible nature, it is, on the other hand, less susceptible to skin sagging since its thinner epidermis suffers less from the effects of gravitational pull.
