Anua Birch 70% Moisture Boosting Serum 30ml

Anua built its reputation on clean, minimal Korean skincare that actually delivers — and the Anua Birch 70% Moisture Boosting Serum is a strong example of what that looks like in practice. The formula replaces the standard water base with 70% Japanese White Birch Water, a naturally harvested birch sap loaded with amino acids, vitamins, minerals, and antioxidants that hydrate the skin at a deeper level than plain water. Its subacidic pH (approximately 5.0–6.0) also means the serum actively works with the skin’s own acid mantle rather than disrupting it — which is one of the reasons it sits so comfortably in sensitive and reactive routines. The texture is genuinely watery and absorbs without any trace of stickiness, making it one of those serums you’ll actually want to layer. Anua Birch 70% Moisture Boosting Toner 250ml

But the birch water is really just the starting point. What gives the Anua Birch 70% Moisture Boosting Serum its staying power is the 10-type Hyaluronic Acid complex, which pulls moisture in at multiple depths — from the surface down into the deeper layers of the epidermis. Panthenol reinforces the barrier so that hydration doesn’t simply evaporate. And the ABC Complex — Allantoin, Betaine, and Cucumber Extract — keeps things calm, balanced, and comfortable, especially for skin that tends toward redness or irritation. Best for anyone dealing with dehydration, barrier disruption, or a generally lackluster complexion that needs a consistent, no-fuss hydration anchor in the routine.

Key Benefits

• Intense, Multi-Depth Hydration — 10 types of Hyaluronic Acid work across different molecular weights to draw moisture into the skin at every layer, from the surface down, delivering a visibly plumper, smoother complexion.
• pH-Balancing Birch Water Base — The Anua Birch 70% Moisture Boosting Serum uses 70% Japanese White Birch Water as its primary base, maintaining the skin’s natural pH while delivering antioxidants, amino acids, and minerals with every drop.
• Soothes and Calms Reactive Skin — The ABC Complex (Allantoin, Betaine, Cucumber Extract) immediately calms irritation, reduces redness, and helps maintain the water-oil balance of sensitive and easily reactive skin types.
• Strengthens the Skin Barrier — Panthenol and Gluconolactone (a gentle PHA) support the moisture barrier, reducing transepidermal water loss and improving overall skin resilience with regular use.
• Fragrance-Free, Vegan, and Non-Comedogenic — Clean formulation with no artificial fragrances, no parabens, no harsh alcohols, and no silicones — safe for sensitive skin and won’t block pores.

Key Ingredients

Here’s what powers the Anua Birch 70% Moisture Boosting Serum:

Betula Platyphylla Japonica Juice (Japanese White Birch Water, 70%) The foundational ingredient that replaces ordinary water in this formula. Japanese White Birch Sap is collected from the Asian white birch tree and contains a naturally occurring profile of sugars, amino acids, organic acids, Vitamins B and C (including naturally occurring niacinamide), and minerals. It hydrates, tones, and creates a light film on the skin’s surface that slows moisture evaporation. Its mildly acidic nature also keeps the formula’s overall pH in the skin-compatible subacidic range, which directly benefits barrier health and ingredient absorption.

10 Types of Hyaluronic Acid Complex What makes this approach to HA genuinely useful is the variety. Different molecular weights of hyaluronic acid behave differently on the skin — high-molecular-weight forms sit at the surface and create a plumping, moisture-locking film, while lower-weight forms and hydrolyzed versions penetrate into deeper epidermal layers to attract and bind water from within. The eight confirmed forms in this formula include Sodium Hyaluronate, Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Sodium Hyaluronate Crosspolymer, Hydrolyzed Sodium Hyaluronate, and Potassium Hyaluronate — together covering the full spectrum of hydration depth.

Panthenol (Pro-Vitamin B5) One of skincare’s most dependable barrier-supporting ingredients. Panthenol converts to pantothenic acid in the skin, directly nourishing the cells that maintain the moisture barrier. It reduces transepidermal water loss, soothes inflammation, and improves the skin’s ability to hold onto the hydration the rest of the formula delivers.

ABC Complex — Allantoin, Betaine, Cucumis Sativus (Cucumber) Fruit Extract Anua’s signature soothing trio. Allantoin is a wound-healing, skin-softening botanical compound that helps speed up the skin’s natural renewal process while calming irritation and redness. Betaine is a sugar beet-derived osmolyte that draws water toward skin cells and protects them from osmotic stress — it also gives the formula a noticeably smooth, non-sticky application feel. Cucumber Fruit Extract rounds things out with instant cooling, anti-inflammatory action and a very high water content that adds another layer of surface hydration.

Gluconolactone (PHA) A gentle polyhydroxy acid that provides mild exfoliation at the skin surface without the sensitivity risk of traditional AHAs. In this formula its primary role is improving skin texture, supporting cell turnover, and helping the skin absorb the hydrating ingredients that follow. PHAs also have humectant properties, so they hydrate as they exfoliate.

Trehalose A naturally occurring sugar that functions as a powerful humectant and osmoprotectant. Trehalose is particularly valued in Korean skincare for its ability to stabilize cell membranes and proteins under stress — it quite literally protects the skin’s structural integrity while pulling moisture in.

Dipotassium Glycyrrhizate (Licorice Root Derivative) A well-regarded anti-inflammatory and brightening agent derived from licorice root. It calms sensitivity, reduces the appearance of redness, and over time can contribute to more even skin tone — complementing the overall soothing tone of this formula.

Tocopherol (Vitamin E) A lipid-soluble antioxidant that protects the skin from free radical damage caused by UV exposure and environmental stressors. It also supports moisture retention and works synergistically with the birch water’s own antioxidant profile.

Biosaccharide Gum-1 A fermentation-derived polysaccharide with excellent skin-calming and long-lasting moisturization properties. It forms a flexible, breathable film on the skin that helps seal in the hydration delivered by the HA complex and birch water.

Best For:

• ✅ Dry and Dehydrated Skin — the 10-HA complex and birch water base deliver sustained moisture to skin that constantly feels tight or parched
• ✅ Oily and Combination Skin — the water-light, non-comedogenic formula hydrates without adding grease or blocking pores
• ✅ Sensitive and Reactive Skin — fragrance-free, hypoallergenic, and built around soothing botanicals
• ✅ Normal Skin — works beautifully as a daily maintenance step that keeps the complexion consistently soft and balanced
• ✅ Post-Procedure or Compromised Barrier Skin — the gentle PHA and barrier-strengthening ingredients support skin recovery

Targets These Concerns:

• Dehydration and persistent skin tightness
• Dull, uneven skin texture from moisture deficit
• Redness and sensitivity triggered by environmental stress
• A weakened or disrupted skin moisture barrier
• Fine lines and plumpness loss caused by dehydration
• Oil-moisture imbalance in combination and oily skin types

Not Recommended For:

• ⚠️ Anyone with a confirmed butylene glycol sensitivity — this ingredient appears high in the formula; patch test before full use
• ⚠️ Skin that is actively broken, raw, or severely inflamed — allow the skin to heal fully before introducing any new serum

How to Use

1. Cleanse and Tone First — Begin with your cleanser and toner to ensure the skin is clean and slightly damp — the Anua Birch 70% Moisture Boosting Serum absorbs best into freshly prepped skin.
2. Dispense and Apply — Take 2-3 drops (or a small pump if using with a dropper) and spread across the entire face using fingertips; start at the centre and blend outward in gentle upward motions.
3. Pat for Absorption — Use light patting motions across the skin to encourage full absorption — do not rub, as the light texture absorbs quickly and patting helps drive it into the skin more effectively.
4. Layer if Needed — For more intensive hydration on particularly dry days or dehydrated skin, wait 30 seconds and apply a second layer; the formula layers beautifully without pilling or feeling heavy.

Use: AM / PM / Both Where in routine: After toner, before moisturizer — as the serum/treatment step Pro Tip: On days when your skin feels especially stripped or reactive, try the 7-skin method — apply the Anua Birch 70% Moisture Boosting Serum in 5-7 thin layers back to back, patting each layer in fully before the next. It’s a well-loved Korean technique for rapidly restoring hydration to a depleted skin barrier.
