Probiotics are live microorganisms that offer several health benefits when consumed in adequate amounts. While most people associate probiotics with gut health, several studies have shown that probiotics can benefit your skin as well. In this article, we will discuss the surprising benefits of probiotics for skin health and healing.
The Connection Between Gut and Skin Health
Your gut and skin interact with each other through a complex network of cells, molecules, and biochemicals. There is mounting evidence that the gut microbiome – the community of microorganisms that live in your intestines – plays a crucial role in maintaining skin health.
For example, a study published in the Journal of Investigative Dermatology found that mice with a healthy gut microbiome had better skin hydration, barrier function, and wound healing compared to mice with an imbalanced gut microbiome.
In humans, several skin conditions such as eczema, acne, and rosacea have been linked to an imbalance in gut bacteria. Therefore, maintaining a healthy gut microbiome through probiotics and a balanced diet can improve your skin health in several ways.
Probiotics for Acne
Acne is a common skin condition that affects up to 50 million Americans annually. While there are several causes of acne, it is primarily driven by an overgrowth of bacteria called Propionibacterium acnes (P. acnes) on the skin.
Several studies have shown that consuming probiotics or applying them topically can reduce the growth of P. acnes and improve acne symptoms. For example, a randomized controlled trial published in the Journal of Dermatological Science found that consuming a probiotic drink containing Lactobacillus acidophilus for 12 weeks reduced the severity of acne lesions in participants compared to a placebo group.
Similarly, a study published in the International Journal of Dermatology found that applying a lotion containing Lactobacillus fermentum for four weeks reduced the number of P. acnes bacteria on the skin and improved acne symptoms in participants.
Probiotics for Eczema
Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, itchy, and inflamed skin. It is caused by a complex interplay of genetic and environmental factors and is often associated with an imbalance in gut bacteria.
A study published in the Journal of Allergy and Clinical Immunology found that infants who were given a probiotic supplement containing Lactobacillus rhamnosus for six months had a significantly reduced risk of developing eczema compared to a placebo group.
Similarly, a systematic review of 31 studies published in the British Journal of Dermatology found that probiotics can improve eczema symptoms in both children and adults. The researchers concluded that probiotics can be a safe and effective option for managing eczema.
Probiotics for Wound Healing
Wound healing is a complex process that involves multiple stages, including inflammation, cell migration, and tissue regeneration. Several factors can affect wound healing, including gut bacteria.
A study published in the Journal of Investigative Dermatology found that mice with a healthy gut microbiome had faster wound healing compared to mice with an imbalanced gut microbiome. The researchers attributed this effect to the anti-inflammatory properties of probiotic bacteria.
Similarly, a study published in the International Wound Journal found that applying a probiotic cream containing Lactobacillus plantarum to diabetic foot ulcers improved wound healing and reduced inflammation in participants compared to a placebo cream.
Conclusion
Probiotics offer several surprising benefits for skin health and healing. They can improve acne symptoms, reduce the risk of eczema, and promote faster wound healing. Therefore, consuming probiotics through food or supplements and using topical probiotic products can improve your skin health in several ways. As always, it is essential to consult with your healthcare provider before starting any new supplement or skincare routine.
