Why Are My Knees So Wrinkly? The Main Cause & 3 Easy Treatment Tips

We tend to focus all our time and attention on our facial skin care routines. But the truth is that wrinkles can show up anywhere—skin is skin, after all. And sometimes the most unexpected of places can bring us anxiety.

I was recently reminded of this when a friend asked me if her knees looked "old." She's my age, which is to say the very young age of 32. We had a good laugh at the somewhat silly question, but for me, it echoed a sentiment I know all too well: I'm always jumping at the chance to talk about my "old-looking hands" because they're, well, freakishly beyond my years. I'm actually not too hung up on their appearance. I figure all I can do is be diligent with my trusted hand cream, wear sunscreen, and not stress too much about it. 

But I still understand the gist of what she was getting at. And honestly, it's very normal to be conscious of an otherwise benign area of the body, knees included. 

First things first is that wrinkles and a crepey appearance happen for the same reason, no matter where it is on the body: loss of collagen and elastin, thinning dermis, and cell damage from environmental stressors like the sun. The knees are no different.

However, what makes the skin on the knees unique is their function. The skin over the knees experiences tons of movement and stretch. It's not necessarily the movement that's the problem—creases and lines are part of a well-functioning face—but as you lose vital skin components like collagen, your skin isn't as able to bounce back from these movements. 

It's actually the same reason places like your mouth, eyes, and forehead develop fine lines before more stationary parts of the face. 

"When your skin barrier is compromised, there is a greater loss of water, resulting in decreased skin turnover, which ultimately leads to crepey skin," board-certified dermatologist, dermatologic surgeon, and founder of Spectrum Skin and Laser Jeremy Brauer, M.D., told us about crepey skin.

Not only will hydration help in the long term, but it offers immediate benefits too. Flooding the skin with moisture can help plump fine lines and make skin appear smoother. 

Sunscreen is the easiest and best way to keep your skin looking healthy and glowing. Given sun damage is accountable for up to 80% of all visible signs of aging1, it's vital that we take protective measures to avoid that damage in the first place. 

In addition, look for antioxidants to help skin neutralize free radical damage, another source of aging. There are plenty of high-quality antioxidants out there, but some of my favorites are vitamin C, E, CoQ10, niacinamide, and panthenol. 

The above two steps are daily must-do's. Meaning: In order to have healthy, vibrant skin, these need to be part of your skin care routine. Treatment steps are add-ons but can really amp up your results as long as you have the basics down.

For fine lines and crepey skin, retinol is the gold-standard ingredient. Retinol can help skin look younger by increasing cell turnover and activating collagen production. 

It's actually become quite the popular ingredient for body formulas, but you can also just apply a facial serum to the area once or twice a week. (Check out our favorite retinol serums here.)
