Body Skin in Midlife: Crepey Arms, Knees, and What Actually Helps

Most midlife skincare conversations stay focused on the face, but plenty of women notice the same crepey texture creeping into their upper arms, elbows, and knees. It’s easy to pour all our attention into our faces, myself included, while body skin quietly gets left out of the routine entirely. But, it deserves just as much care as facial skin does.

Today I’m breaking down why body skin crepes differently than facial skin, and which ingredients and products actually help.

What Crepiness and Laxity Actually Mean

Crepiness refers to skin that has taken on a thin, finely wrinkled texture, similar to crepe paper. Laxity is a related but slightly different concept, referring to skin that has lost its ability to snap back into place and instead sits looser against the body. The two often show up together, since both come down to the same underlying loss of collagen, elastin, and hydration. I go into the biology behind this in much more depth in my post on why skin feels drier, thinner, and crepey in midlife, and most of what applies to facial skin applies here too.

Why Body Skin Crepes Differently Than Facial Skin

Arms and knees actually tend to show crepiness earlier and more visibly than the face for a few specific reasons. The skin on the upper arms and around the knees is thinner to begin with and has fewer oil glands, so it holds onto moisture less efficiently. Knees also sit over bony, mobile joints with very little underlying fat padding, which makes any loss of elasticity more visually obvious every time you bend or straighten your leg.

Sun exposure plays a large role too. Arms and legs spend decades absorbing UV exposure, often with far less sunscreen attention than the face ever gets. That cumulative damage breaks down collagen over time in the exact same way it does on facial skin, just with less product intervention along the way to help offset it.

Exfoliation for Body Skin

Gentle exfoliation helps smooth crepey texture by clearing away the buildup of dead skin cells that accumulates as cell turnover slows. When that surface layer is cleared regularly, the skin underneath reflects light more evenly and looks smoother, which reduces the appearance of fine crepey lines even though it isn’t rebuilding collagen directly.

Glycolic acid is a great option for the body specifically. It’s a smaller molecule than lactic acid, so it penetrates more effectively, and the skin on your arms, legs, and knees can generally tolerate a strength that would be too aggressive for facial skin. I like starting simple with Naturium’s Smoother Glycolic Acid Exfoliating Body Wash in the shower a few times a week, which builds gentle exfoliation right into your routine without adding an extra step. If you want something more concentrated, Prequel’s Multi-Acid Milk Peel combines glycolic, mandelic, and lactic acids at a higher strength and works well applied after showering on nights you want a deeper treatment.

Retinoids for Body Skin

Retinoids work on body skin the same way they work on the face, by encouraging faster, healthier cell turnover and supporting collagen production over time. Because body skin is thinner in these areas and typically gets far less consistent retinoid exposure than the face, introducing one can make a real difference in texture and firmness with consistent use over months.

If you already use tretinoin on your face, know that the same prescription can generally be used on the body, and the approach is identical: start slowly, two to three nights a week, and let your skin build tolerance before increasing frequency. If you’d rather use an over-the-counter option, Gold Bond Age Renew Retinol Overnight Body & Face Lotion and Paula’s Choice Skin-Smoothing Retinol Body Treatment are both solid, easy ways to introduce retinol to the body without a prescription. Whichever route you choose, expect gradual improvement rather than an overnight transformation. Retinoids soften and refine the look of crepey skin, but they don’t rebuild lost elastin, which is part of why realistic expectations matter here.

Moisturizer and Sunscreen for the Body

A well-formulated body moisturizer with humectants and emollients helps plump the skin temporarily and makes crepiness less visible day to day, even though it isn’t a structural fix. Applying it right after showering, while skin is still slightly damp, helps lock in more hydration. La Roche-Posay’s Lipikar AP+M Triple Repair Cream is one I genuinely reach for, it’s rich without feeling heavy, and works well as a nightly layer on areas that need extra support.

Naturium’s Urea 5% Body Serum also earns a place in this step, even though it’s a serum rather than a moisturizer, since urea helps soften rough, thickened texture on top of hydrating, which makes it especially useful on knees and elbows specifically. I like applying it right before my body cream for an extra layer of hydration, so it works alongside your moisturizer rather than replacing it.

Sunscreen matters just as much on the body as it does on the face. Arms in particular take on enormous cumulative sun exposure over a lifetime, and consistent SPF is one of the few things that actually slows down further collagen breakdown rather than just masking the surface. A few body sunscreens that feel good enough to actually use daily: Supergoop’s PLAY Everyday Lotion SPF 50, Sun Bum’s Daily Body Sunscreen SPF 50, and Coola’s Hydrating Sunscreen Lotion SPF 30. If your arms and hands are still exposed during the day, spending a few extra seconds applying sunscreen there is worth it. 

Realistic Expectations

None of these steps will fully reverse crepiness, and that’s worth saying plainly. Elastin in particular doesn’t regenerate well once it’s damaged, which means the goal here is improving skin quality and slowing progression rather than restoring skin to how it looked decades ago. I go into this more in my post on why skin starts to sag, if you want the fuller picture. With consistent use, most women do see softer texture and slightly firmer-feeling skin, just gradually and modestly.

It’s Okay Either Way

Crepey skin on your arms and knees is a completely normal part of getting older, and there’s nothing wrong with it showing up. It’s absolutely fine to put some effort into a body routine if it makes your skin feel more comfortable or if you simply enjoy the process. It’s equally fine to do nothing at all. Neither choice needs justifying, and your skin doesn’t need fixing to be worth taking care of.

In next week’s post, I’ll be covering morning versus night routines in midlife, and how to structure each one so your skin actually benefits from what you’re using and when.
