HIDAKA KOMBU & SHIRAKABA OIL IN SERUM

A light, fluid oil-in-serum that helps minimise the appearance of pores and leaves skin feeling smooth A two-phase serum that combines the benefits of oil and lotion in one. The upper layer brings together a highly moisturising oil-extracted Hidaka Kombu extract and Kalahari melon oil, whilst the lower layer is formulated with birch sap harvested from birch trees, distilled water drawn from fresh young birch leaves, and a water-extracted Hidaka Kombu extract. The birch sap — which can be collected only during a brief window before the snow melts, just once a year — together with distilled water from the fresh young leaves and the concentrated essence of Hidaka kombu from the sea, are all held within a single bottle. In summer, skin can feel oily from sweat and sebum, making dryness seem unlikely — yet the skin's inner layers are often more parched than we realise. Wiping away sweat also removes the skin's natural oils and moisture, which is why it matters to replenish and maintain the skin's balance of water and oil. This serum helps to restore moisture to skin that has become dry, balance its water and oil levels, and encourage a firmer, more luminous-looking complexion. Light and non-sticky — a welcome companion for summer skin. POINT 1 A fresh, hydrating texture — comfortable to use even through the heat of summer We set out to create the freshest and fluid texture of any SHIRO oil-in-serum.
