One of the best skin serum products I have used, leaves skin smooth and minimizes wrinkles.
As far as anti-aging serums go, this is one of the best. And it's a great value. I have used some of the more expensive serums like Cellex-C and Dr. Gross. Jack Black is right up there with them, it only costs less. The Protein Boost Serum works really well. You will see and feel some tightening right away but you will see a noticeable improvement in your skins overall appearance in about a week. I highly recommend this product. Give it a try, you won't be disappointed.
The more i read the more it seems a serum is a necessity in a skin care routine and this one is amazing! Ive been using it for a year and it really works wonderful. jack black in general is pretty amazing also per ounce this is a great deal, most serums are 50 dollars an ounce
I’ve been using the jack black skin serum for years It is a very good product for keeping your skin healthy and looking youthful. I recently purchased the skin serum and the bottle leaked inside. Grooming lounge rectified the problem fast
Really great serum.. been using it for years
