A large scientific review and multiple clinical trials suggest that microbiome-targeted approaches, including probiotics and prebiotics, may improve inflammatory skin conditions and visible signs of aging.

New scientific research is expanding the understanding of how probiotics and prebiotics influence skin health, with evidence suggesting benefits for conditions ranging from eczema and acne to wrinkles and ultraviolet-related skin damage. A comprehensive scoping review published in Nutrition Reviews analyzed more than 500 studies examining the relationship between the gut and skin microbiomes, finding consistent associations between microbiome modulation and improved dermatological outcomes.
Probiotics, defined as live beneficial microorganisms such as Lactobacillus and Bifidobacterium species, and prebiotics, which are nondigestible compounds that support the growth of these microbes, have traditionally been studied for digestive health. The review found that their effects extend beyond the gut, influencing systemic inflammation and immune regulation that are closely tied to skin function.
Across studies focused on atopic dermatitis, commonly known as eczema, approximately 72% reported improvements in disease severity following probiotic supplementation, while more than half showed preventive benefits when probiotics were administered during pregnancy or early infancy. These findings suggest that early microbiome support may reduce the likelihood or severity of inflammatory skin conditions later in life.
Evidence was also reported for acne, where probiotics and synbiotics—formulations combining probiotics and prebiotics—were associated with reductions in lesion counts and overall severity. Researchers noted that these effects may result from decreased systemic inflammation and suppression of pathogenic bacteria implicated in acne development.
Anti-aging outcomes were examined in a smaller but notable set of trials. In one double-blind, placebo-controlled study lasting eight weeks, participants who received prebiotic supplementation experienced significant reductions in wrinkle length and depth compared with placebo recipients. Improvements in skin hydration and overall appearance were also documented, suggesting that supporting beneficial microbial activity may influence skin structure and resilience.
The review identified several challenges within the current body of research, including wide variation in probiotic strains, dosing regimens and study designs, which complicates direct comparisons across trials. Additionally, many studies lacked detailed reporting on participants’ dietary patterns, age distribution and ethnic background, factors that can influence microbiome composition and skin health outcomes.
Researchers emphasized the need for larger, standardized clinical trials to determine which strains and dosages are most effective for specific skin conditions. They also highlighted gaps in data for older adults and for conditions such as rosacea, pigment disorders and skin cancer, where evidence remains limited.
Prebiotics emerged as a particularly promising area of investigation due to their role in promoting the production of short-chain fatty acids, compounds known to support skin barrier function and reduce inflammation. Unlike some conventional cosmetic or dermatologic interventions, prebiotics were generally well tolerated in the studies reviewed.
The findings add to a growing body of literature examining the gut–skin axis and suggest that microbiome-focused strategies may complement existing approaches to skin care and disease management. Authors of the review concluded that while current evidence supports meaningful associations between probiotics, prebiotics and skin health, further research is required to establish causation and develop clear clinical guidance.
