If the beauty and youthfulness of the skin is often talked about in the magazines, most of the time they only describe a few tricks to mask the symptoms of aging. This is not the spirit of aesthetic medicine where two elements remain essential, as for any medical act: a good diagnosis and a good prevention. In aesthetic medicine, the skin is treated as an organ in its own right, thus the beauty and youthfulness of the skin goes far beyond the aesthetic framework alone: it is a systemic approach, which aims at preventing the causes and at correcting the symptoms. Keeping a young skin means first and foremost keeping the skin functional.
What is young skin?
Understanding how to preserve the youthful beauty of a skin presupposes a good understanding of where its youthful qualities come from.
It is a beautiful firm skin
It is the collagen fibers of the dermis that give the skin its firmness and part of its tone. These very resistant proteins are produced by the fibroblasts which are the "factory cells" of the dermis. When their cellular activity decreases, the production of collagen decreases in quantity and quality, resulting in less firm and less toned skin. This is how skin slackening develops, because the skin stretches under the effect of gravity.
It is a young and supple skin
Beautiful skin is contoured and full: this is linked to the hydration of the dermis and the presence of hyaluronic acid. This macromolecule acts as a chemical sponge, being able to fix up to 1000 times its weight in water. The bigger the hyaluronic acid "sponge" is, the more supple and curved the skin is.
One should not confound poorly hydrated skin (dermis) and dry skin (epidermal film with a lipidic surfactant of poor quality).
It is an elastic skin
The youthfulness of a skin is also characterized by its elasticity, without skin folds: this is linked to the presence of special protein fibers called elastin fibers. They are also found in the connective tissue that envelops the skin muscles, or aponeurosis of the SMAS (Superficial Muscular Aponeurotic System).
An elastic and young skin does not look creased or wrinkled, because it immediately regains its tension at the slightest skin fold.
It is a luminous and radiant complexion.
Young skin is characterized by a radiant and glowing appearance.
This radiance of the skin implies a homogeneous reflection of light and thus a very regular and smooth skin texture.
The more even and smoother the skin texture is, the more luminous the skin will be.
What is skin aging?
The cellular metabolism that changes with age will affect both fibroblasts (factory cells of the dermis) and melanocytes (cells that produce melanin pigments).
How do fibroblasts participate in skin aging?
Fibroblasts are the conductors for all the components of the dermis. The alteration of hyaluronic acid synthesis results in a less hydrated dermis, hence a skin that loses its radiance.
Above all, however, it will lose volume, leading to the creation of wrinkles, where the epidermis collapses because the underlying support tissues have softened. This is how the nasolabial fold is formed, which gives the lower face a severe or tired look.
This loss of volume also causes the skin to become thinner: in places where it is already naturally thin (eyelids, hands...), it can become "transparent", revealing bony areas or veins: this is the skeletonization of the hands or dark circles.
This loss of volume finally hollows out the face, for example on the forehead or temples.
The alteration of collagen fibers results in a less toned and firm skin, causing skin slackening. Under the effect of gravity, the tissues stretch, with skin sagging and displacement of volumes, as can be seen on an eyebrow ptosis or the sagging of the oval of the face, which gives an inverted V shape.
Skin folds may fall downwards, in the form of baleen on the neck or arm (bat-like arms). If sagging skin is severe and coupled with excess skin, cosmetic medicine must give way to surgery, with a facelift type method.
The alteration of the elastin fibres means that the skin or connective tissue will keep the persistent folds. This is the mechanism of dynamic wrinkles, which combines the hypercontraction of the skin muscles with the loss of the skin's elastic fibers and SMAS. These expression wrinkles mainly affect the upper part of the face (forehead wrinkles, frown lines, crow's feet...) and give you a severe, weary or worried expression.
How do melanocytes alter the youthfulness of a skin?
Melanocytes tend to accumulate melanin pigments with age : thus age spots or brown spots (lentigos) appear, which cause the skin to lose its radiance and luminosity.
What are the key points for keeping a young skin?
Your aesthetic doctor at the Clinique des Champs Elysées will carry out a diagnosis to suggest the best strategy.
It is then possible to perform a facial check-up.
Stimulate your spontaneous rejuvenation
These techniques presuppose that the skin is still of good quality, in order to take advantage of its natural capacities associated with normal healing (self-healing of the skin). Medical LED phototherapy, medical waves, tissue inducers, medium peeling, lasers or growth factor injections thus use these cell renewal properties, via stem cells and growth factors, injected or induced.
Remove the signs of aging
Your aesthetic doctor can remove superficial imperfections with a vascular laser, cryolipolysis, injections of hyaluronic acid or botulinum toxin, a gentle peeling, a facelift without surgery...
It is a set of methods to smooth wrinkles and regain soft skin.
Restore the volume of the face
To recreate volumes, the physician chooses a resorbable filler, either alone (hyaluronic acid injections) or combined with tissue inducers.
