From Forest to Formula — The Serum Duo

Two serums. The same Nordic foundation. Completely different hours.

In the morning it needs defending. By evening it needs renewing. Most serums ask you to pick one. The Serum Duo covers the full 24-hour cycle your skin actually works on — one formula for what the day demands, one for what the night makes possible.

Both begin with Finnish birch sap — at over half the formula by weight in each. Not water. A living base that carries minerals, amino acids, and naturally occurring xylitol deeper than water reaches. In harmony with the birch sap: concentrated Chaga extract, carried deeper by that living base, delivering antioxidant defense before the day has asked anything of your skin.

From that foundation, each serum divides the day.

Birch Dew Daytime Serum — the morning defense and luminosity layer.
Arctic cloudberry leads — one of the rarest berry oils in Nordic nature, its omega fatty acid profile almost singular in the plant world. Its natural vitamin C works alongside a stabilized vitamin C derivative and biofermented niacinamide — three brightening mechanisms building quietly, in the same direction, over time. A probiotic complex supports the skin's own microbiome. The Nordic Botanical Complex settles everything before the actives begin.
This is the protection layer. What goes between clean skin and the world.

Twilight Birch Nighttime Serum — the overnight renewal layer.
Nordic lingonberry leads — in two forms, doing two different things. Lingonberry stem cells at 2% for the appearance of firmness and even tone. Lingonberry seed oil for deep antioxidant protection while skin does its most considered work. One rebuilds. One defends. They were chosen to reinforce each other.

Alongside them: Bakuchiol, as both fruit extract and isolated active, for the appearance of renewal without retinol's photosensitivity or irritation. For skin navigating hormonal change — where sensitivity often increases — this is not a compromise. It is the more considered path to the same destination. The Nordic Botanical Complex, with both nettle root and nettle leaf, settles the skin before the active layer begins. Two forms of the same plant. Two distinct phytochemical fractions. Both needed.

This is the renewal layer. What your skin does with the night, supported.

† We're committed to fragrance transparency. The Bilberry Dream Cream scent is over 99% natural — a blend of pure essential oils and a botanical absolute. The remaining trace (less than 0.01%) consists of nature-identical fragrance molecules that mirror compounds found in nature, used to round out the scent profile.
*Contains botanical extracts and essential oils. As with all active botanical formulas, individual sensitivity varies. Patch test recommended for reactive skin. Discontinue use if irritation occurs. Not for use on broken or compromised skin. Consult a healthcare professional if you are pregnant, nursing, or have a known skin condition.
