What are stretch marks, and where do they come from?

Stretch marks or striae are red, sometimes purplish or white stripes on the body, several centimetres long by a few millimetres wide. They develop when part of the body grows too fast. Too fast for the skin. This causes the connective tissue to tear inside. These cracks are also visible on the surface and can sometimes be painful. Stretch marks are actually subcutaneous scars. Over time, the redness decreases and becomes white, which is also when the stretch marks are most difficult to treat.


The reference treatment for scars, and in this case for stretch marks, is based on fractional radio frequency. At Skincenters we chose Lurtronic’s Infini. The technique consists of destroying the damaged fibres and then stimulating the production of new collagen in the scar to make the scar more supple and less thick. To do this, applicators equipped with microneedles are used to treat the areas in depth and ensure the best possible results. The treatment is carried out in 3 to 6 sessions of 30 to 60 minutes. Secondly, other technologies can be used, such as Laser, and more specifically a combination of an ND:Yap and an ER:Yag laser: The first go deep inside the skin to stimulate the production of collagen while the Erbium laser will puncture the epidermis to cause both a collagen stimulation and a skin renewal, with these treatments the scar will close from the inside out.

Note: the duration and results of a treatment can vary from person to person and are therefore only indicative.
