I have become concerned about my neck. I am starting to see the first signs of sag and I am not happy about it. Not at all. I think nothing makes you look older than a loosening jaw line. Well that and aging hands. So when I heard about Perricone MD Cold Plasma Sub-D cream and the effects it has on the neck…I was more than willing to give it a try. I mean I had nothing to lose right?Cold Plasma Sub-D offers a non-invasive treatment to sculpt and tighten the appearance of skin along the chin and jaw-line. This cream uses a revolutionary patented delivery system of DMAE and caffeine for optimal firming and toning benefits. It also helps soothe, hydrate and brighten dull, sagging skin with essential amino acids. Yet, it is specifically targeted for the delicate area of the neck and chin to help address the loss of elasticity. Better still, it’s free of parabens, sulfates, phthalates, synthetic dyes and synthetic fragrances. So according to Perricone MD studies; 82% felt the appearance of their chin/jaw-line was more well toned and tight; more firm and saw a decrease in the appearance of a double chin or sagging under the chin/jaw-line. And 79% noticed their chin/jaw-line looked crisper and more defined. Well that sounded good enough for me. At least to give it a try. So I been following the recommended application and have been using Cold Plasma Sub-D twice a day (applied along the contours of my jaw-line, chin, neck, décolletage, and behind the ears). Now, I will tell you…it smells a little funky at first. Like sulfur (rotten eggs). However, the smell fades quickly. Besides, if it works…I don’t care what it smells like! So does it work? Well after a week of use I can tell you I do see an improvement. Thank God. Now is it an 82% improvement? Not yet, but I’d say at least a 30% and I’m going to keep using it.
