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.\u003c\/p\u003e\n\u003cp\u003eIn 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.\u003cbr\u003eThis 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr class=\"hr-1\"\u003e\n\u003cdiv class=\"item-stack\" style=\"row-gap: 0.8rem; margin-top: 3.2rem;\"\u003e\n\u003cdiv class=\"point-title\" style=\"margin: 0;\"\u003e\u003cstrong\u003ePOINT 1\u003c\/strong\u003e\n\u003cp class=\"u-fw-medium\" style=\"margin: 0;\"\u003eA fresh, hydrating texture — comfortable to use even through the heat of summer\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp style=\"margin-top: 0;\"\u003eWe set out to create the freshest and fluid texture of any SHIRO oil-in-serum.

It is rich in vitamins and minerals, and is said to contain higher levels of vitamin A and B vitamins (B1, B2, and folate) — nutrients that support healthy-looking skin — compared to Gagome Kombu. Its natural thickening component, fucoidan, is known for its moisture-retaining properties, helping to maintain hydration and protect skin from dryness. At SHIRO, we use kombu that, despite being highly nutritious, receives a low market grade and cannot be sold at a fair price. Rather than let it go to waste, we put it to good use in our products.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/shiro-shiro.jp\/ec\/product_images\/ingredients-shirakaba-03.jpg\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBirch (Shirakaba)—Aibetsu \/ Horokanai \/ Etanbetsu , Hokkaido\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSensitive to heat and dryness, birch trees thrive in cold climates and grow widely across Hokkaido in Japan. Resilient by nature, they are among the first to take root and grow, even on barren ground, drawing nutrients from the soil before other plants can. The sap collected before the snow melts — drawn up to nourish the tree's first young leaves of spring — is known as the 'water of life'. The bark and young leaves are also rich in vitamin C, flavonoids (a type of polyphenol), and tannins, which are said to help address a range of skin concerns.\u003c\/p\u003e\n\u003cp\u003eSize：60mL\u003c\/p\u003e","brand":"SHIRO Online Store | Hong Kong","offers":[{"title":"Default Title","offer_id":43690489741425,"sku":"101-900034-00042","price":380.0,"currency_code":"HKD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2409\/3297\/files\/13442_aacdfbbd-1778-4aad-ba8d-95106c3e29dc.jpg?v=1784858210","url":"https:\/\/shiro-shiro.hk\/en\/products\/2026-hidaka-kombu-shirakaba-oil-in-serum","provider":"SHIRO Online Store | Hong Kong","version":"1.0","type":"link"}
