Prebiotics have become one of the most talked-about ingredients in modern skincare — and for good reason. But what actually are they?
The skin microbiome, briefly
Your skin is home to a community of microorganisms known as the skin microbiome. When this community is balanced, skin tends to feel calmer and more comfortable. Prebiotics are ingredients that help support and maintain that balance.
What prebiotics do
Think of prebiotics as supportive nutrients for your skin's natural ecosystem. In skincare formulas, they're used to help support the microbiome and maintain a sense of balance — which is why they pair so well with hydrating ingredients like hyaluronic acid and sodium PCA.
Who they suit
Because they're gentle and supportive rather than active and intense, prebiotic formulas are a comfortable choice for most skin types, including sensitive skin. You'll find prebiotics across the Replēn range, from our Jelly Serum to our Face Mist.
