Jack Black Protein Booster Skin Serum for Men, 2oz.

This is my daily skincare regimen, and has been for more than a decade. There is nothing better for men.

I am a man with melon in my skin. I started using this product after a recommendation from a friend. This stuff works! Smells good and makes my skin feel....simply clean and smooth. It's clearly a bit pricey, but worth the price. Plus it last for months. A little goes a long ways. Definitely recommend for us guys that want to do the bare minimum with the BEST results when it comes to maintaining our looks. Use it with some good cleanser prior to serum, and a moisturizer after using the serum.

I use this product everyday. Love how it smooths out my face and feels great

This is my third time buying. My skin looks and feels healthy.

A must product for everyday use. I apply this prior to the Dry Erase. The combination is ultra moisturizing without any greasy residue or excess shine.

[This review was collected as part of a promotion.] I love this serum and largely give it most of the credit for why I've managed to currently look ten years younger than the folks I graduated with from college lol

I think this is one of the best anti-aging products out there. It has all the necessary ingredients, goes on light, and doesn't irritate my skin. It's improved the look of my skin. I'll never stop using this.

I'm uncertain but a number of years ago, this formula used to be so effective. Now it seems a bit 'blah'. The consistency and the scent are the same, the softness gained by the ingredients is there, but the effectiveness in the long term is nothing spectacular and doesn't work as good as it did a number of years ago. It seems as if it's an overpriced 'after shave balm' now, perhaps the company reformulated or added more 'fillers' or 'slip agents' thereby diluting the 'recipe'? I have used this for almost two months now and it's not working, its a bit of a waste of money, wish I could return it. Again, overpriced after shave balm....the 'effective ingredients' suffered in whatever changes were made to the formula.

I've been using Jack Black Daily Clean Face Wash, SPF Moisturizer, and Line Smoother for 8+ years and decided to add this to my regimen a couple years ago. Something recently changed with this product and it looks, smells, and feels completely different. I don't know that I'll keep using it after I finish this bottle but it would be nice to get a little warning that it's not the same product anymore. This bottle isn't cheap.

This is a different formula. Have used for many years. Not the same product as before. Not worth the money now
