You can't talk about gut health without mentioning probiotics, and if this latest innovation catches on, these good bacteria could become synonymous with skin health, too.
In the same way that fermented foods are helpful to the natural, good bacteria in your stomach, probiotics can help sort out the bacteria on your skin.
If you are picturing kombucha and yoghurt on your face, stop. Probiotic skincare looks (and smells) just like your regular products - with one big advantage.
According to Sara Quilter, founder of Tailor skincare, probiotics act as the body's peacekeepers, helping to keep things in a delicate balance or symbiosis. She first discovered the benefits of probiotics in skincare after learning how they could unlock minerals in soil and help plants grow.
She's since released Tailor Renew Probiotic Serum, which contains lysate to stimulate the skin's natural renewal process.
"Your skin has its own microbiome [community of microbes] and, much like the gut, it's important to keep this in balance so that pathogenic bacteria don't take over or become imbalanced," she explains.
Using probiotics in skincare dates back to ancient Egypt where Cleopatra is said to have bathed in sour milk – these 21st-century innovations, though, offer a much more pleasant experience and the results don't lie.
