DESCRIPTION
Skin has its own microbiome, and the idea behind this serum is to work with it rather than stripping and rebuilding as most actives do. It uses the same spore-based technology as the rest of the Gutsi range, applied topically instead of taken by mouth, which is a genuinely unusual approach in skincare. The texture is a light silken liquid that absorbs quickly, so it layers under a moisturiser without pilling. Fifteen millilitres is small, but it is a serum used by the drop rather than the pump. A reasonable option if strong actives have left your skin reactive.
