Anua Birch 70% Moisture Boosting serum 30ml

Anua Birch 70% Moisture Boosting Serum is a lightweight, fast-absorbing daily hydration serum from Anua, built around one of skincare’s most compelling functional bases: 70% Japanese White Birch Water (Betula Platyphylla Japonica Juice) — a naturally sap-derived ingredient that replaces plain water in the formula and sets it apart from conventional hydrating serums from its very first ingredient. The formula is subacidic by design, formulated at a slightly acidic pH that closely mirrors the skin’s own natural pH range, making it uniquely effective at maintaining the skin’s acid mantle, supporting the microbiome, and reinforcing the moisture barrier without disrupting the skin’s internal balance. The serum’s consistency is refreshingly watery yet substantive — it spreads effortlessly, absorbs almost instantly without any sticky or occlusive residue, and leaves the skin feeling noticeably soft, smooth, and hydrated from the first use. It can also be layered two to three times for more concentrated moisture delivery on particularly dry or dehydrated days. Fragrance-free, non-comedogenic, hypoallergenic, vegan, and cruelty-free. Suitable for all skin types including sensitive, oily, dry, and combination. Made in South Korea.

Betula Platyphylla Japonica Juice — Japanese White Birch Water — is the defining ingredient of this formula and functions as both the primary solvent and the primary active, constituting 70% of the total formula by weight. Birch sap is a naturally occurring spring harvest collected from Japanese white birch trees; it is rich in naturally occurring sugars (xylitol, fructose, glucose), amino acids, vitamins, minerals, and antioxidant polyphenols. In skincare, birch water acts as a highly effective natural humectant and moisture-barrier protectant — it hydrates the skin’s surface layers, helps prevent transepidermal water loss, and delivers a concentrated supply of skin-compatible nutrients with every application. Its subacidic nature contributes directly to the formula’s pH-balancing function, making it particularly beneficial for skin whose acid mantle has been compromised by harsh cleansers, environmental stressors, or over-exfoliation. The ABC Complex is the formula’s dedicated soothing and balancing system, comprising three synergistic ingredients: Allantoin, Betaine, and Cucumis Sativus (Cucumber) Fruit Extract. Allantoin is a naturally derived skin-conditioning agent with well-documented emollient, wound-healing, and anti-irritant properties — it softens and smooths the skin, encourages healthy cell turnover, and calms reactive or sensitised skin. Betaine, derived from sugar beet, is a naturally occurring osmoprotectant and humectant that adds additional skin-soothing, hydration-boosting, and barrier-supportive properties, while simultaneously contributing to the formula’s pleasant, non-sticky skin feel. Cucumber Fruit Extract is a cooling, antioxidant-rich extract known for its astringent and oil-balancing properties, its ability to calm redness and irritation, and its contribution to maintaining the skin’s water-oil balance — making the formula equally effective for oily and combination skin types that need hydration without adding excess weight or shine. The 10-type Hyaluronic Acid complex delivers comprehensive multi-depth humectant hydration throughout all layers of the stratum corneum. Sodium Hyaluronate is the standard salt form of hyaluronic acid — a powerful humectant that attracts and holds up to 1,000 times its weight in water on the skin surface. Hydroxypropyltrimonium Hyaluronate is a cationic, positively-charged derivative of HA that binds strongly to the negatively charged skin surface, forming a substantive, wash-resistant moisture film that provides durable hydration with exceptional retention. Sodium Acetylated Hyaluronate (Hyaluronan Acetylate) is a lipophilically modified form of HA with enhanced skin retention and longer-lasting moisture delivery compared to standard HA. Hydrolyzed Hyaluronic Acid has a reduced molecular weight that enables deeper penetration into the upper layers of the epidermis. Hyaluronic Acid in its free acid form provides direct, highly potent humectancy. Sodium Hyaluronate Crosspolymer is a high-molecular-weight cross-linked HA that sits on the skin surface forming a durable moisture-sealing film. Hydrolyzed Sodium Hyaluronate offers enhanced dermal penetration for deeper-layer moisture replenishment. Potassium Hyaluronate, the potassium salt form, contributes further surface hydration and electrolyte balance. Together these eight confirmed HA forms — alongside additional HA variants in the full proprietary blend — work at multiple molecular weights, penetration depths, and skin retention times to deliver sustained, multi-layer hydration that persists long after application. Panthenol (Pro-Vitamin B5) strengthens the skin barrier, soothes inflammation and irritation, and delivers continuous conditioning moisture to keep skin feeling comfortable, soft, and non-reactive throughout the day. Glycerin and Diglycerin are both skin-identical humectants that draw moisture into the skin and prevent transepidermal water loss, contributing to long-lasting surface hydration and smoothness. Trehalose is a naturally occurring disaccharide sugar with exceptional water-binding and cryoprotective properties, well documented for its ability to protect skin cell membranes from dehydration-induced stress and environmental damage — a functional ingredient that adds meaningful depth to the formula’s moisture retention system. Dipotassium Glycyrrhizate is a potassium salt of glycyrrhizinic acid derived from liquorice root, known for its potent anti-inflammatory, soothing, and redness-reducing properties — a key ingredient for calming reactive, sensitised, or irritation-prone skin. Biosaccharide Gum-1 is a fermentation-derived polysaccharide with humectant, soothing, and film-forming properties that contribute both to moisture retention and to a silky, comfortable skin feel. Gluconolactone is a polyhydroxy acid (PHA) that provides very gentle surface exfoliation at a skin-compatible level, subtly refining skin texture and smoothness over time without irritation, while also contributing to the formula’s pH stability. Malachite Extract, derived from the gemstone mineral malachite, is a rich source of copper and naturally occurring antioxidants that help neutralise free radical damage, support collagen synthesis, and improve skin clarity and tone. Tocopherol (Vitamin E) provides antioxidant protection against oxidative stress and reinforces the skin’s natural lipid barrier. The formula also incorporates four plant botanical extracts: Gardenia Florida Fruit Extract (Cape Jasmine — brightening and antioxidant), Ulmus Davidiana Root Extract (Korean Elm Root — deeply hydrating polysaccharides), Pueraria Lobata Root Extract (Kudzu Root — isoflavone-rich botanical with firming and antioxidant properties), and Pinus Palustris Leaf Extract (Longleaf Pine — antioxidant and skin-conditioning), as well as Oenothera Biennis (Evening Primrose) Flower Extract which provides gamma-linolenic acid-related barrier-nourishing and anti-inflammatory support.
