If you’ve been browsing our range and keep seeing the same ingredients crop up, there’s a reason. Nordic skincare draws on a very specific botanical vocabulary — plants that have survived, and thrived, in extreme cold, low light and short growing seasons. That stress gives them unusual protective compounds, many of which are clinically validated for their effects on the skin barrier, antioxidant defence, and hydration. Here are three ingredients you’ll encounter throughout our collection, and why they matter.
Arctic Cloudberry (Rubus chamaemorus)
Cloudberry grows wild above the treeline across Scandinavia and Finland, hugging boggy, peat-rich ground at altitudes where few other fruiting plants survive. It’s extraordinarily slow to ripen — the narrow window lasts just a few weeks each Arctic summer — and the seeds must endure freeze-thaw cycles that would destroy most plant tissue. The oil cold-pressed from those seeds is the reward for that endurance.
Cloudberry seed oil is one of the richest plant sources of tocopherols (vitamin E), including the rare alpha and gamma forms. Tocopherols are lipid-soluble antioxidants that integrate directly into cell membranes, neutralising reactive oxygen species before they can disrupt skin-cell DNA and collagen structures. Research published in Skin Pharmacology and Physiology confirms that topical vitamin E significantly reduces UV-induced oxidative stress — relevant context for Irish skin that often receives UV exposure in diffuse, unpredictable bursts rather than prolonged sun.
Beyond antioxidant defence, cloudberry oil contains a balanced ratio of omega-3 and omega-6 essential fatty acids — specifically alpha-linolenic (omega-3) and linoleic acid (omega-6). These are integral components of the skin’s lipid matrix. When that matrix is depleted — as it often is in Irish climates where wind and central heating strip moisture constantly — the skin barrier becomes permeable: water escapes (transepidermal water loss, or TEWL), irritants enter, and redness follows. Topically applied linoleic acid helps restore that barrier by replenishing the ceramide-adjacent lipids that hold skin cells together.
You’ll find cloudberry featured in several face oils and treatment formulas in our range, particularly from Nörre Nordic, whose formulations are built around Finnish botanicals.
Birch Sap (Betula pendula)
In early spring — sometimes as early as February in Finland — birch trees begin drawing up sap from the soil before a single leaf opens. The window during which this sap flows is brief, often less than two weeks, and it must be collected by tapping the trunk and catching the flow in vessels. Traditionally consumed as a tonic drink across Scandinavia and the Baltic states, birch sap has found a second life as a high-performance skincare base.
What makes birch sap interesting as a skincare ingredient is its composition. Unlike purified water — which serves as an inert solvent in most formulas — birch sap contains xylitol (a naturally occurring polyol and humectant), vitamins B1, B2, B6, and C, minerals including calcium, magnesium, potassium and manganese, and amino acids. Xylitol in particular is noteworthy: it draws moisture from the environment into the skin, similar in mechanism to glycerin and hyaluronic acid, but with a lighter skin-feel. Studies on xylitol’s moisturising properties have shown it helps maintain epidermal hydration, making it especially valuable in low-humidity environments.
For Irish skin, the relevance is direct. Ireland’s Atlantic climate means the air can be both damp and wind-dry simultaneously — high humidity outdoors, but central heating and open fires create dry indoor air that dehydrates skin overnight. A birch sap base in a moisturiser or serum works with the skin’s own hydration mechanisms rather than simply sitting on top.
When birch sap is used to replace water in a formula, it’s not just a marketing point. Every water molecule in that product carries with it a complement of micronutrients and the humectant activity of xylitol. That’s a different category of base ingredient — and one that makes sense for products positioned around skin health rather than sensory experience alone.
Sea Buckthorn (Hippophæ rhamnoides)
You’ll know sea buckthorn by its vivid colour. The bright orange berries of this thorny shrub, which grows across coastal dunes and river valleys from Scandinavia to Central Asia, contain one of the most concentrated arrays of skin-active nutrients found in any plant. The oil — which can be extracted from either the berries or the seeds — ranges in colour from deep amber to vivid orange, and it will stain if applied undiluted.
Sea buckthorn’s most distinctive contribution is omega-7, or palmitoleic acid. This fatty acid is rare in plant sources — it occurs naturally in human sebum, which is why it integrates so well with skin. Palmitoleic acid plays a role in skin repair, wound healing and the maintenance of the stratum corneum. Clinical evidence reviewed in the Journal of Cosmetic Dermatology supports sea buckthorn’s efficacy in improving skin elasticity and reducing transepidermal water loss in dry and mature skin types.
Beyond omega-7, sea buckthorn berry oil is extraordinarily high in carotenoids — the compounds that give it its vivid orange colour. Beta-carotene, lycopene and zeaxanthin are all present in significant concentrations. These act as antioxidants within the skin, reducing the cellular damage caused by UV exposure and environmental pollution. For those living in Irish cities, where traffic pollution is a real skin stressor, this antioxidant burden matters.

Why These Ingredients Matter Specifically for Irish Skin
Ireland’s climate is deceptively challenging for skin. The combination of Atlantic wind, soft water (which can disrupt the skin’s acid mantle over time), variable UV index, and the drying effect of central heating creates a particular set of stressors. Most mainstream skincare is formulated for European continental climates or US coastal climates — neither maps well to the west coast of Ireland.
Nordic botanicals, by contrast, evolved in conditions that share several characteristics with the Irish climate: cool temperatures, high wind exposure, damp air, and significant seasonal light variation. The protective mechanisms those plants developed — dense antioxidant profiles, high essential fatty acid content, natural humectants — translate directly to what human skin needs in similar environmental conditions. We explore this in more detail in Why Nordic Skincare Suits Irish Skin.
How to Incorporate These Ingredients Into Your Routine
Cloudberry oil: Best applied in the evening as part of a face oil or treatment step. Apply after water-based serums and before your moisturiser, or blend 2–3 drops into your moisturiser for a hybrid texture. See our full face oils range.
Birch sap: This is most often a background ingredient rather than a standalone product — it replaces water in the formula. Look for Betula alba juice or Betula pendula juice high on the INCI list. See our serum collection for products built around Nordic botanical bases.
Sea buckthorn: Given the intense pigment, look for products where it appears mid-to-low in the INCI list — typically 1–5% concentration. Browse our face oil range for suitable options. For a full routine context, see How to Build a Nordic Skincare Routine.
Frequently Asked Questions
Is cloudberry oil suitable for oily or acne-prone skin?
Yes — cloudberry seed oil has a relatively high linoleic acid content. Research suggests that acne-prone skin is often deficient in linoleic acid, which contributes to comedone formation. Unlike oleic acid-heavy oils (which can clog pores), linoleic-rich oils are generally non-comedogenic and light enough for most skin types.
What’s the difference between sea buckthorn berry oil and sea buckthorn seed oil?
Both come from the same plant but differ in colour, composition, and use. Berry oil is vivid orange, extremely high in carotenoids and omega-7, but intensely pigmented. Seed oil is pale yellow, lighter in texture, and contains more omega-3 and omega-6. Most skincare formulations use seed oil or a careful blend of both to balance efficacy with usability.
Can birch sap cause allergies?
People with birch pollen allergy should exercise caution. Birch pollen is one of the most common aeroallergens in Ireland and Northern Europe, and some individuals exhibit cross-reactivity to birch-derived ingredients. If you have a confirmed birch pollen allergy, patch-test any birch sap product on the inner arm for 24 hours before facial use.
Are these ingredients safe during pregnancy?
All three — cloudberry oil, birch sap, and sea buckthorn oil — are generally considered safe for topical use during pregnancy. They are botanical oils and plant waters with no known teratogenic compounds at typical skincare concentrations. Consult your midwife or GP if you have any concerns, particularly regarding other active ingredients in the same formula.
