I have used this for three years. I have been a sun worshipper and a smoker in some of my 58 years. I do believe the results speak for themselves. My skin is very nice and surprisingly not very wrinkled. I know genes play a part but I truly believe in this serum. I will use it as long as I'm alive
Have only used it a week and my face seems to be smoother and more; dare I say supple?? I think it will be my new best friend!
I've been using their PRO LS All-In-One Face Treatment and had fantastic results. While I always had high marks for the Jack Black RxSeries Protein Booster Serum, I thought I would give this product a try. I've been using it for about a week now and I can already see and feel a significant change. My skin has a smoother, all-around tone and looks and feels well moisturized. I will definitely be adding this to my daily face-car regimen. For what it's worth, I'm 45 years old and this stuff keeps my looking fresh)
This little bottle packs a whole lot of punch! This is a powerful serum I've noticed an improvement in my complexion after about a week
Incredible serum that boosts skin and awakens worn-out skin caused by years of smoking and not getting enough sleep
