Recent marks, old scars… every skin has its own story. To help your skin gently regenerate, Soin-et-Nature offers specialized treatments to minimize facial scars. Thanks to formulas containing hyaluronic acid, silicone, or reparative active ingredients, these products promote skin suppleness, fade visible marks, and support the skin’s natural healing process .
More detailsScar formation can take up to two years—this is known as the maturation period. During this time, you can positively influence the appearance of the scar. The sooner you start, the better the results. Scars that are treated with care are generally much more supple, lighter in color, and less raised.
External scars typically form after an injury to the deeper layers of the skin. A small cut or minor laceration often affects only the uppermost layer of the skin, the epidermis. In this case, a new, intact layer of skin forms from the lower layer of the epidermis and closes the wound.
This is not the case when the injury reaches the dermis, the middle layer of the skin: In this case, it leaves behind scar tissue composed of collagen fibers that lack elasticity. When a scar forms, protection takes precedence over aesthetics, because when the skin is damaged, pathogens can easily enter the body. It is therefore not surprising that the body’s defenses attempt to close the wound as quickly as possible. It is therefore not uncommon for an irregular scar to form. Scar formation is the final, visible stage of the healing process.
Skin injuries that leave a more or less visible scar after healing are, unfortunately, unavoidable throughout life. Effective wound care, infection-free healing, and each person’s genetic predisposition are key factors in minimizing the marks left by the injury.
Most of the time, a fresh scar is red and raised. Over time, the scar tissue fades and flattens slightly. The affected area remains pale and hairless, and generally has a smooth appearance. This substitute skin is less elastic and continues to change for about two years. To improve the appearance of scars from the very first signs of skin repair, regular use of cosmetic dermatology products formulated for cellular regeneration can promote optimal healing while reducing redness, thickness, and irregularities. This can eventually lead to hardening and adhesions. The scar remodeling process can cause typical symptoms such as
Furthermore, depending on their size and location, scars can be bothersome for aesthetic reasons. It is not always possible to cover them with clothing. In sensitive areas such as the face, proper scar management is therefore crucial.
To better manage skin lesions and prevent the formation of unsightly scars, it is necessary to understand the different phases of wound healing.
The vascular response is the body’s immediate reaction to skin injury. It is accompanied by rapid vasoconstriction, which promotes hemostasis. Blood that leaks from damaged blood vessels into the injured tissue coagulates to form a scab, which temporarily isolates the skin tissue from the surrounding environment. As soon as the wound appears, regional vasodilation occurs. Vascular permeability increases, triggering a cascade of inflammatory reactions characterized by erythema, edema, pain, and local hyperthermia. Fibrin deposits and clots rapidly cover the wound bed to promote hemostasis. This phase results in the formation of a red thrombus: the clot.
The inflammatory phase begins rapidly and lasts approximately 3 days. Neutrophils appear as early as the first hour of wound healing. This phase is essential for combating surrounding bacteria and for creating an environment conducive to healing. The primary purpose of inflammation is to attract polymorphonuclear cells (microphages) to the injured area, followed by macrophages (phagocytosis) and plasma proteins, which can:
During this inflammatory phase, leukocytes infiltrate the site, remove waste products (clots and damaged cells), and release growth factors and pro-inflammatory cytokines that trigger the proliferation phase.
After a few days, the influx of neutrophils stops, giving way to macrophages, which will remain predominant for the remainder of the inflammatory process.
The second stage involves rebuilding tissue and blood vessels. The process of new blood vessels growing from preexisting onesis called angiogenesis . This phase begins 2 to 3 days after cleansing. Reconstruction of the dermis begins 3 to 4 days after the injury. This tissue is called granulation tissue because of its granular appearance. These granules correspond to the numerous blood vessels that make up the tissue. During its formation, a coordinated migration of macrophages, fibroblasts, and blood vessels within the lesion is observed. The wound is red, shiny, moderately exudative, and appears “fleshy.”
Epidermalization (or epithelialization) is centripetal: it proceeds from the outside toward the inside. Through the proliferation and confluence of keratinocytes, it begins both by multiplication from the wound edges and by migration within the granulation tissue. Certain factors, such as the smoothness of the wound surface, are critical for the contiguous colonization of keratinocytes. A definitive basal membrane forms, with proliferation in the thickness of the wound to restore a normal epidermis. This process takes up to 21 days (the average time for a wound to close). The wound is often pinkish in color, with minimal exudate and is superficial.
Once epidermalization is complete, the tissue is referred to as scar tissue. Between the 25th and 30th day, the collagen in the primary scar breaks down and the scar remodels, becoming more flexible, smoother, and softer to the touch. This remodeling leads to the formation of the scar, which will be permanent after 6 to 12 months. Note that the new tissue remains fragile (its tensile strength will not exceed 70–80% of what it was before the wound appeared) and is highly sensitive to ultraviolet rays, hence the need to use broad-spectrum sunscreen on a scar for at least 2 years.
