ACI (Advanced Cosmetic Intervention) has approval to sell their new GFX device for glabellar wrinkles. Right out of a science fiction film, this radiofrequency ablation tool uses a nerve stimulator to identify the nerves that innervate the frown muscles between the eyebrows and then uses energy to block the action of these nerves. How long does is last? Studies have proven that it lasts at least 8 months (twice as long as Botox) but could potentially last for years and years. That's a lot fewer trips to the medspa for the Botox junkie!
