From Inflammaging to Everyday Practice

Hi, Bob Root here, Keys Scientist.

I want to connect the dots between a technical term—inflammaging—and the practical daily routines you can control.

Inflammaging is the idea that, as we get older, a low-level fire of inflammation slowly burns in the background. It is subtle; you do not feel sick, but your body is constantly responding to small ongoing irritations. One of those irritations may be right on the surface: your skin.

When the skin barrier is compromised—dry, thin, itchy, or constantly irritated—it becomes a source of those signals. The body reads that as damage and responds by releasing inflammatory molecules into the bloodstream. Over years, that adds up.

Here is where everyday habits matter. Using a well-designed barrier moisturizer on a large portion of your body is not just about comfort; it is about quieting that signal. At Keys, when we created our barrier-focused products, we chose ingredients and textures specifically for mature, reactive, and sensitive skin. The idea is simple: hydrate, nourish, and support the barrier without introducing new irritants.

For example, after a shower, pat your skin dry—don’t scrub—and apply a Keys® moisturizer while the skin is still slightly damp. Focus on areas that tend to be driest: legs, arms, back, and torso. This helps lock in water, support the lipid matrix, and reduce the tiny cracks and micro-injuries that can drive irritability and inflammation.

The emerging research suggests that, especially in adults over 70, this kind of consistent barrier support may help reduce inflammatory markers in the blood and stabilize the skin microbiome. My goal at Keys has always been to give you tools that fit into your daily life but are rooted in that deeper science.

You cannot control every aspect of aging, but you can choose to treat your skin barrier as an important part of your whole-body health strategy.
