A very nice video which will show you how we can treat stretch marks. The injection is made into the dermis. Each stretch is supposed to blow during a few minutes. When the CO2 gas is absorbed by the body, a redness aspect remains visible for a few minutes to 1 or 2 hours.
Stretch marks will progressively fade. With a collagen synthesis stimulated, their aspect is smoothed. Pigmentation seems to return to normal.
