It’s a physiological fact…your neck muscles are just like every other muscle in your body. They respond to resistance exercises in exactly the same way. If you exercise your neck, chin and jaw muscles they will firm and lift, if you don’t they will weaken and sag..just like any other muscle, whether its your butt, thighs or abs. But you need to stick with the exercises for 6 to 8 weeks to get the best results. All the ladies I used in the before and after shots are local mums in my home town…their results are genuine and living proof that the Neckline Slimmer works. Best Regards. Paul Younane, England, UK
