Clear your skin with prebiotics, not probiotics.

Clear your skin with prebiotics, not probiotics.

Prebiotic supplements have been shown to have potential in improving skin health by modulating the gut-skin axis and promoting the growth of beneficial gut bacteria, which in turn may reduce inflammation and improve skin barrier function. Here are 8 bullet points discussing the evidence:

  • Promoting healthy skin microbiome: Prebiotics can selectively promote the growth of beneficial skin microbiota, such as Staphylococcus epidermidis, which have been associated with healthy skin and protective immune response (1).
  • Reducing inflammation: Prebiotic supplements have been shown to reduce inflammatory markers in the body, which may lead to improvements in skin health. A study in 2014 demonstrated that supplementation with fructooligosaccharides (FOS) led to a reduction in pro-inflammatory cytokines in healthy adults (2).
  • Improving skin barrier function: Prebiotics have been shown to improve skin barrier function by promoting the growth of beneficial gut bacteria, such as Bifidobacterium and Lactobacillus, which may improve skin hydration and reduce transepidermal water loss (3).
  • Reducing symptoms of atopic dermatitis: Prebiotic supplementation has shown promise in reducing symptoms of atopic dermatitis, a common inflammatory skin condition. A study in 2014 found that supplementation with galactooligosaccharides (GOS) resulted in a reduction in eczema severity in infants with atopic dermatitis (4).
  • Reducing symptoms of acne: Prebiotics may also have potential in reducing symptoms of acne by reducing inflammation and improving skin barrier function. A study in 2013 demonstrated that supplementation with a combination of FOS and GOS led to a reduction in acne lesions in adults with acne vulgaris (5).
  • Improving wound healing: Prebiotics have been shown to improve wound healing by promoting the growth of beneficial gut bacteria and reducing inflammation. A study in 2018 found that supplementation with FOS and inulin improved wound healing in rats by reducing inflammation and increasing collagen deposition (6).
  • Reducing photodamage: Prebiotic supplementation may also have potential in reducing photodamage, which can lead to skin aging and skin cancer. A study in 2018 showed that supplementation with lactulose and inulin reduced markers of photodamage in mice exposed to ultraviolet radiation (7).
  • Enhancing skin hydration: Prebiotic supplementation may improve skin hydration by promoting the growth of beneficial gut bacteria, which in turn may improve skin barrier function. A study in 2015 demonstrated that supplementation with GOS led to improved skin hydration in healthy adults (8).

Overall, while more research is needed to fully understand the potential benefits of prebiotics on skin health, the available evidence suggests that they may have promise in improving skin barrier function, reducing inflammation, and reducing symptoms of certain skin conditions such as atopic dermatitis and acne.
