Twilight Birch Nighttime Serum

Restore. Rejuvenate.

30ml · 1 fl oz

In Finnish autumn, the light drops fast. One hour the forest is copper and amber; the next it has turned inward — dark, concentrated, still. This is the hour when everything accumulated through the long summer is present. The lingonberry holds its color through the first frost. The birch stands patient. This serum was made for exactly this — the hours when skin does its most considered work.

Skin that wakes up more than it went to sleep. A nighttime serum built on the highest Chaga concentration in the range, with Nordic lingonberry in two forms for overnight renewal and protection — and bakuchiol, clinically studied to deliver retinol-comparable results without retinol's sensitivity.

From Forest to Formula

Twilight Birch begins with over 73% birch — Finnish birch sap as the base, and wild Chaga mushroom extract at its highest concentration in the Kasvi Beauty range. At night, when skin's renewal activity rises and the contact window is longer, a base that carries actives deeper becomes not a preference but a purpose.

The Nordic Botanical Complex — yarrow, nettle root and leaf, plantain — is read differently at night. Nettle root and nettle leaf are not the same ingredient: the leaf brings mineral density, silica, and anti-inflammatory compounds; the root carries distinct phytochemical fractions with their own traditional applications. Both are here because both are needed. The complex settles the skin before the active layer begins its work.

Then, Nordic lingonberry in two forms. Lingonberry stem cells at 2% — studied for their ability to support the appearance of firmness and even tone. Lingonberry seed oil at 2% — exceptional antioxidant protection for the skin. One defends. The other rebuilds. They were chosen to reinforce each other.

Bakuchiol is present as both fruit extract and isolated active at the clinically studied concentration. It is considered a natural alternative to retinol, with similar studied results. For skin navigating hormonal change, this is not a compromise. It is the considered path.

The same galactoglucomannan emulsifier from upcycled Finnish spruce sawdust creates the texture — ECOCERT COSMOS certified, film-forming, biologically active. The silk-derived humectant complex holds overnight hydration without stickiness.

How to Use

Each evening, after cleansing. 1–2 pumps pressed gently into face, neck, and décolletage. The warm color can transfer if over-applied — less is right. Let absorb fully, then follow with Bilberry Dream Cream.

Evening ritual: Twilight Birch → Bilberry Dream Cream → Nordic Renewal Elixir (2–3 evenings per week)

Or simply: Twilight Birch → Nordic Renewal Elixir

Hero Ingredients +

Birch Sap + Wild Chaga Mushroom Extract · The Overnight Foundation

Betula alba juice · Inonotus obliquus · Highest Chaga concentration in the range

What it does:

Finnish birch sap replaces water entirely, carrying minerals, amino acids, and xylitol deeper into skin. Wild Chaga mushroom extract at the highest level in the range — betulinic acid, melanin complex, and polysaccharides with antioxidant activity among the most extensively studied in the fungal world. The warm brown of this serum is the extract. Not a colorant — evidence of concentration. Independently assessed for antioxidant capacity, this extract demonstrated potent free radical neutralization even at low concentrations — and the effect increases with concentration.

Why it's here:

At night, the contact window is longer and renewal activity rises. A base that carries — rather than dilutes — changes what the actives can do. What is here is here with purpose, at the highest level in this range.

Nordic Lingonberry · Two Forms, One Berry

Vaccinium vitis-idaea stem cells · Vaccinium vitis-idaea seed oil · Nordic origin · 2% + 2%

What it does:

Stem cells at 2%, studied for their ability to increase the skin's own antioxidant mechanisms, protect against UV and infrared damage, and support the appearance of firmness and even tone. Seed oil at 2% — the highest alpha-linolenic acid content of any berry seed oil, plus gamma-tocotrienol, a form of vitamin E of exceptional antioxidant potency. It nourishes and rebuilds the barrier through the overnight hours in which renewal is possible.

Why it's here:

Two mechanisms. One ingredient. The stem cells defend the conditions that allow renewal. The seed oil nourishes the barrier through which renewal expresses itself. This is the hero of Twilight Birch — and it belongs to the Nordic forest in a way that cannot be borrowed.

Nordic Botanical Complex

Yarrow · Nettle root and leaf · Plantain · Proprietary blend

What it does:

Three boreal plants. Nettle root and leaf are distinct — the leaf brings mineral density, silica, and anti-inflammatory compounds; the root carries different phytochemical fractions with their own traditional applications. Yarrow for calming. Plantain for allantoin.

Why it's here:

Skin navigating hormonal change is more reactive. Before the actives can do their overnight work, the skin needs to be settled enough to receive them. This complex creates those conditions. Quietly.

Bakuchiol · The Considered Alternative

Psoralea corylifolia fruit extract + isolated active · Clinical concentration · Two forms

What it does:

Not a retinoid — chemically unrelated to vitamin A. A 2019 randomised double-blind study in the British Journal of Dermatology showed comparable results to retinol on wrinkle surface area and hyperpigmentation, with significantly less scaling and stinging. Present as both fruit extract and isolated active for depth of delivery.

Why it's here:

Retinol is frequently not tolerated by skin navigating hormonal change. Bakuchiol delivers the same functional outcome through a different pathway — without photosensitivity, without the irritation that interrupts consistency. Consistency is where results come from.

Silk-Derived Humectant Complex

Fibroin glycoside · Two forms · Upcycled, naturally derived

What it does:

A clinically studied silk-derived humectant complex, in two complementary forms, clinically proven to deliver up to 24-hour hydration comparable to mid and high molecular weight hyaluronic acid — without HA's humidity-dependence. Binds to skin keratin and stays through the day. No stickiness. No tackiness.

Why it's here:

The renewal work overnight requires a hydration environment that holds. This provides it — upcycled, naturally derived, staying on skin while everything else does its work.
