What if a workout also changes the skin?

A small 2023 study asked a surprisingly direct question. Researchers assigned 61 sedentary, middle-aged Japanese women to aerobic or resistance training for 16 weeks; 56 completed the study.

Both groups improved measured skin elasticity and aspects of upper-dermal structure. Resistance training also showed an increase in dermal thickness.

Interesting. Early, too.

There was no non-exercising comparison group. The study was short, involved one narrow population, and included researchers affiliated with a cosmetics company. It does not establish visible age reversal or a replacement for dermatologic care.

What makes it worth following is the connection: skin biology may respond to changes that begin elsewhere in the body.

That is a richer research question than whether one more product belongs on the shelf.

The Arising follows these connections carefully—what changed, how it was measured, and what still needs to be tested.

Skin is living tissue. There is much more to learn about how we care for it.

A closer reading

The investigators did more than measure the skin. They also exposed cultured human dermal fibroblasts to participants’ plasma collected before and after training and examined expression of genes related to the extracellular matrix. Those experiments offered possible biological explanations, but they did not directly establish the entire causal pathway in people.

The absence of a non-exercising group matters. Comparing two exercise programs can identify differences between them, yet changes that appear in both groups may have other explanations. The intervention also involved supervised training, which may not resemble the way every person exercises outside a study.

Dermal thickness and elasticity are measurements. They are not interchangeable with fewer wrinkles, improved skin disease, slower whole-body aging or longer life. Even the paper’s use of the word “rejuvenates” in its title should be read against the outcomes and design.

The useful next step is replication: larger and more diverse groups, a suitable comparison condition, longer observation and outcomes that matter to people. The connection to strength and movement is biologically interesting. Its clinical significance remains an open question. This is a look back at a 2023 experiment, not a new 2026 breakthrough.
