A 12-week investigation indicates that pomegranate extract may boost skin elasticity by influencing gut bacteria, presenting a possible alternative to supplements that rely on collagen.
How the study worked
The research team examined two dosages of Pomanox, a pomegranate-derived extract, in a group of 64 women ranging from 30 to 65 years old. One half of the participants received a low dose of 367 mg each day, another half took a high dose of 700 mg, and the remaining participants were given a placebo. All volunteers followed the regimen daily, and the investigators recorded skin elasticity, hydration levels, and microbial composition at the beginning, after four weeks, and at the conclusion of the trial.
Results showed that the lower dose often matched or even surpassed the higher dose in effect, challenging the notion that a larger amount automatically yields greater benefit. This pattern mirrors the behavior of several plant-derived compounds, whose impacts do not increase in a straight-line fashion with intake.
Gut bacteria as the key
Pomegranate’s active molecules are not readily absorbed in their original form; instead, gut microbes convert them into substances called urolithins, especially urolithin A. Urine analyses demonstrated that the levels of this metabolite rose in 62 of the women during the trial. Participants who exhibited an increase in urolithin A showed a 12% greater gain in skin elasticity compared with the placebo group after the 12-week period.

This finding points to a partial dependence of the extract’s benefit on the gut microbiota’s capacity to process it, establishing a direct link between intestinal health and skin firmness. The investigators also observed alterations in both gut and skin microbial populations over the course of the study.
Unlike most oral beauty products that depend on collagen, the extract did not modify blood markers associated with collagen synthesis. That outcome suggests that other physiological pathways may contribute to the observed improvements in skin condition.
Skin health therefore involves more than topical applications or collagen intake; inflammation within the gut and the balance of microbes appear to play a significant role, and this trial adds to the growing body of evidence that internal factors affect elasticity and hydration.
The trial was not originally designed to assess elasticity; it primarily targeted dark-spot reduction, which showed no notable change. The skin-related benefits emerged as secondary observations, and the modest sample size limits the ability to generalize the results. Additional, larger-scale investigations are required to verify whether the effects persist in broader populations.
