Twilight Birch Nighttime Serum

Curated with Nordic plant wisdom, this definitive overnight serum is your first step after evening cleansing to target loss of elasticity and hormonal skin shifts. This formula leads with the regenerative power of the arctic forest, utilizing Nordic lingonberry in two potent forms—antioxidant-dense seed oil and cellular-level stem cells—to deeply renew the skin matrix. To supercharge this botanical active, bakuchiol acts as a secondary, plant-derived retinol alternative to smooth fine lines without the classic overnight irritation. Built on a living base of birch sap and chaga mushroom, it delivers a cushioned, plump complexion that is perfectly prepped for your nightly cream or oil.

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.
