HOW TO MAKE A SCAR DISAPPEAR?
B. TYPES OF SCARS
1. Atrophic scars:
these are the most frequent scars. Due to a loss of dermal thickness at the site of the lesions, they appear as a depression at the level of the skin surface. These scars do not naturally recede. There are three types of atrophic scars, classified according to their shape, their contour, their depth: ice pick scars, called Icepick or V-Shaped, depressed scars with shallow edges called Boxcar or U-Shaped and depressed scars with pronounced edges called Rolling or M-shaped.
2. Hypertrophic scars:
these lesions are raised (but less than keloid scars) and red. Simple hypertrophic scars disappear naturally after 12 to 18 months.
3. Keloid scars:
the cheloid scar does not go away on its own and is often associated with pain and / or itching. It appears as a raised lesion, slightly colored between white, red, brown and pink. Its specific form is due to an abnormal proliferation of skin tissue.
Acne problems, surgery, a burn or even an accident can leave marks on the skin of the face or body. Stigmata of these events, scars can be a source of psychological suffering. To reduce or remove a scar, surgery is not necessarily necessary. There are aesthetic medicine techniques that can remove a scar.
A. WHAT IS A SCAR? T
he appearance of a scar results from a phenomenon of tissue repair of a skin lesion. As soon as the dermis is affected (burn, wound, pimples), the skin activates a physiological healing mechanism. Starting immediately after trauma, this process aims to deeply repair skin tissue and takes place in several stages. Variable according to the extent of the lesion, the overall healing time can reach between 1 year and 1.5 years.
The healing phases are as follows:
- The coagulation phase: a blood clot forms as a result of the bleeding and turns into a scab
- The inflammatory phase or debridement phase: leukocytes activate to clean the lesion and destroy any foreign bodies in the tissue.
- This phase results in an inflammatory reaction leading to possible redness and swelling (edema) and an increase in temperature in the affected area.
- The proliferative phase: the dermis and the epidermis begin to rebuild.
- These neo-tissues are initially very imperfect.
- The remodeling phase:
the structure and strength of the wound improves as does its visual appearance. Gradually, the scar becomes more flexible.
The quality of healing changes depending on the size of the lesions, the quality of the skin, the state of health of the person. Indeed, the regenerative capacity of the skin depends on several factors (age, vascular pathologies, nutritional deficiencies, smoking).
When abnormalities affect the healing phenomenon, visible and permanent scars form on the affected area. There are several techniques in non-invasive aesthetics and aesthetic medicine to reduce a scar.
D. TREATMENT OF SCARS: HOW TO MAKE SCARS DISAPPEAR
- Diabetes or severe insufficiencies such as renal failure, heart failure ...
- The pregnancy Wearing a pacemaker or cardiac defibrillator Isotretinoin treatment stopped for less than a year or anti-acne treatment in progress
- Skin infection or herpes
- Recent cosmetic intervention such as surgery, laser, dermabrasion
- Dark phototypes
- Skin contact allergies
For the laser, the consequences of the session and the side effects depend on the technique used and vary from the simple feeling of being overheated to greater swelling and the appearance of scabs
