Kiehl's Age Defender Power Face Serum for Men, Anti-Aging Firming Serum, Retinol-Free, with Cypress Extract & Adenosine, 2.5 fl oz

Finally a serum made for men! I've been using this for two months, and my skin looks firmer and more rested. It absorbs fast and doesn't leave any greasy residue. Love that it's retinol-free, so no irritation. Worth every penny.

I'm 45 and this serum has definitely helped with fine lines on my forehead and around my eyes. It's not a drastic change, but noticeable. The bottle lasts a long time, and it doesn't clash with my moisturizer.

I was skeptical about an anti-aging serum, but my wife noticed a difference in my skin texture. It feels smoother and more elastic. No irritation, and the scent is light and masculine. I've already ordered a backup.

It's a decent serum, but I didn't see much of a change. Maybe I need to use it longer. It feels nice on the skin though, and I like that it's fragrance-free. Might repurchase if on sale.

This serum has reduced the look of my crow's feet a bit. It's lightweight and doesn't clog my pores. The price is steep, but I got it on sale. I'd recommend it for men over 40.

I've struggled with fine lines and dull skin. This serum has transformed my skin. It's now smoother, more even, and definitely looks firmer. The fact that it's retinol-free is perfect because I have sensitive skin. Very pleased.

I like how my skin feels after using this serum—smooth and moisturized. However, it takes a minute to absorb, and my face feels slightly tacky at first. But that goes away after I put on sunscreen. Overall, good product.

I broke out after using this for a week. Maybe I'm allergic to something in it. It's too bad because I liked the texture. If you have sensitive skin, patch test first.

I've been using this for three months, and I can see a slight improvement in my skin's elasticity. It's easy to incorporate into my morning routine. The pump dispenser is convenient, and a little goes a long way. Would recommend.

At first, I thought the price was ridiculous, but after 4 weeks, my skin looks noticeably better. The fine lines around my mouth are fading, and my skin feels stronger. This is now a staple in my skincare. Buy it.
