The patient's state of health - illnesses, regular medication, any known problems with healing scars, should always be communicated to the practitioner. If the acne scars are in a clearly visible place, after the laser treatment the skin will be swollen and reddened for some time, the skin must be carefully protected from the sun and it is necessary to apply special creams. Therefore, it is not recommended to have the treatment right before you go on holiday if you plan to sunbathe or take part in a photo shoot. Laser treatment is not performed during pregnancy.
