What I actually liked most about the v-line chin shaping masks was something that surprised me - It made me more aware of my posture and of how I sit with the way I hold my neck and align my chin with my clavicle. I know it has actually more instant benefits than postural awareness, like moisturization, collagen and elastin replenishment, and a more smooth and defined jawline, but I honestly thought it was the most helpful thing to be made aware of how greatly just the way I align my neck and jaw makes not only the appearance and contours of the chin better, more nourished and slender, but it actually makes you FEEL BETTER and less pain, shoulder and neck and jaw pain and stress and muscle tension, from just having the heightened awareness that using the v-line masks provides to you, in a purely structural and physiological way.There is a whole science of how having good posture kind of is its own impetus for creating future posture that is more correctly anatomical aligned, and thus HEALTHY - and I think that these masks really do that in a way that I wasn’t at all expecting. It’s kind of relaxing to go to bed after wearing one for 20-30 minutes, because it’s as if it removes a large percentage of my jaw/neck/even shoulder pain, and for someone with TMJ and chronic migraines, I really appreciate that aspect of the masks. Of course, I love the natural dermatological nourishment, as well as the cosmetic enhancement of having a tighter and firmer, structured chin and jawline, as everyone would, but the postural awareness side effects of wearing the masks are really a massive unexpected bonus that I believe anyone could really get help from that kind of experience. It’s like the mask works double time. I love it!!!
