For a few years now, injections of hyaluronic acid have gradually become more accessible: these days it's not just the celebrities on the red carpet who can get their hands on them, even men have succumbed to using this almost painless treatment! There's no doubt that these intradermal injections have an incredible effect on frown lines, those on your forehead, crow's feet and the smile lines around your mouth and near your nose. And all of that without any scalpels! In 30 short minutes, and after a few small pricks in your skin, only a few millimetres deep, all the lines are filled, your skin is smoother and the contours of your face appear firmer for 6 to 9 months.
