Skin Lift. We know that exercise benefits our muscles, brain, heart and other organs but does it improve our skin? A new study published in Scientific Reports says yes. Exercise scientists at Ritsumeikan University in Kyoto, Japan found that both aerobic and weight training changed gene expression and improved the underlying health of facial skin cells and tissue but the most significant effects happened when people lifted weights.

For the study, 56 sedentary, middle-aged women either cycled for 30 minutes, twice a week or lifted weights for 30 minutes, twice a week. Before they began their assigned exercise program, the scientists used ultrasound and other measures to assess the elasticity, thickness, and dermal layers of the women’s facial skin. The researchers also took blood, checking it for various substances and added it to isolated facial skin cells in Petri dishes.

They repeated all the tests after 16 weeks of exercise and found that the participants’ facial skin had improved elasticity. The skin’s extracellular matrix, which is the biological foundation that gives skin tissue structure, was also denser and genes that are part of the creation of skin collagen were more active. These are all factors of skin rejuvenation and happened in both groups.

But only the weight training group saw an increase in the thickness of the skin’s dermal layer. The team believes this was due to resistance training increasing the activity of several specialized genes that create proteins that build and strengthen connective tissue. (The team did not assess the appearance of the women’s skin).

According to the study’s lead author, the findings suggest that the skin “is strongly influenced not only be external factors such as UV radiation and dryness but also by internal factors” like gene expression and inflammation, which exercise can change.

Some limitations: The study was small, short and only included middle-aged, Japanese, sedentary females with no control group so more and larger experiments are needed.
