Whole-herb infusion. Sea buckthorn fruit oil.
Slowly infused herbs
Harmony’s wild-foraged yarrow flowers, Douglas fir tips, nettle and horsetail, with locally grown organic comfrey leaf and marshmallow root, steep directly in the moisturizing oils for several weeks.
Guided by herbal practice, ethnobotany and modern research, we select the blend for the plants’ properties, suitability for oil extraction and natural aroma. Slow infusion draws their oil-soluble constituents and aromatic compounds into the oils before filtering.
Why sea buckthorn fruit oil?
Fruit-pulp oil is an unusually rich botanical source of palmitoleic acid—an omega-7 fatty acid also found in skin lipids. Its carotenoids are plant pigments with antioxidant properties that also give Harmony its warm golden-orange color.
Research into sea buckthorn oils includes their effects on skin cells, oxidative stress and moisture retention. Fruit-pulp oil has also been investigated in laboratory studies of skin-cell responses to UVB exposure. Its distinctive composition and this developing body of research inform its place alongside Harmony’s herbal infusion and richer moisturizing oils.
Sea buckthorn—composition and research
Sea buckthorn—composition and research
A distinctive fruit oil
Compositional studies show that sea buckthorn pulp oil contains substantially more palmitoleic acid than its seed oil. High concentrations of this omega-7 fatty acid are uncommon among plant oils. Fruit oil also contains carotenoids, including compounds studied for their antioxidant properties.
Research in skin cells
In a 2024 laboratory study, sea buckthorn pulp oil reduced collagen breakdown following UVB exposure in cultured human skin cells. The researchers also examined palmitoleic acid as a contributor to the observed effects.
Together, compositional and experimental research helps explain the interest in sea buckthorn fruit oil as a skincare ingredient.

How to use
How to use
After cleansing, mist your face and neck with a hydrosol or leave your skin slightly damp with water.
Apply the serum to damp skin, gently pressing it into your face and neck. Adjust the amount to your skin’s needs and preferred feel. Apply a little more to areas that feel dry or tight.
Use morning or evening. If using sunscreen, apply it after the serum.
Pair with a hydrosol: Hydrosols hydrate the skin, while the serum softens it and helps retain moisture. Apply the serum while your skin is still damp.
Ingredients
Ingredients
These organic oils form Harmony’s moisturizing foundation. Together, they soften roughness, help retain moisture and create its rich, comforting feel.
Foundation oils
- Organic jojoba oil — Jojoba is a liquid plant wax with a composition distinct from most botanical oils. It conditions the skin and helps maintain a soft, supple feel.
- Organic argan oil — Argan contributes conditioning fatty acids and helps skin retain moisture, bringing richness and comfort to the blend.
- Organic apricot kernel oil — Apricot kernel oil provides conditioning fatty acids and helps soften dry skin. It contributes to Harmony’s smooth, supple feel.
- Organic rosehip oil — Rosehip contributes essential fatty acids, including linoleic and alpha-linolenic acids. We choose it to condition dry, rough-feeling skin and help leave it softer and smoother.
- Organic castor oil — Castor oil is naturally thick and rich in ricinoleic acid. It gives Harmony body and contributes to the lasting, enveloping feel that distinguishes it from Glow.
Slow herbal infusion
- Wild-foraged yarrow flowers — Yarrow flowers contain volatile terpenes and sesquiterpene lactones. The flowering herb was traditionally prepared as an external wash or compress.
- Wild-foraged Douglas fir tips — Douglas fir tips contain aromatic monoterpenes, including pinenes. They contribute a crisp conifer scent to Harmony's otherwise earthy herbal blend.
- Organic comfrey leaf — We use locally grown comfrey leaves rather than the roots. Comfrey has a long history in European salve-making; leaf constituents include allantoin and rosmarinic acid.
- Organic marshmallow root — Marshmallow is a perennial in the mallow family with roots rich in mucilage, a group of polysaccharides valued for their silky texture. Herbalists have traditionally used the root in preparations for dry, sensitive skin.
- Wild-foraged nettle — Known for its sting, nettle is also a familiar herb in traditional skin and hair care. Its deep-green leaves contain chlorophyll and carotenoids, and we wild-forage them in Washington for Harmony’s infusion.
- Wild-foraged horsetail — Horsetail is a spore-producing plant from a lineage older than flowering plants. Its finely ridged, jointed stems are naturally rich in silica, and the herb has a long history in traditional skin and hair preparations.
Added after infusion
- Sea buckthorn fruit oil — Selected for its distinctive fatty-acid composition, including omega-7 palmitoleic acid, and naturally occurring carotenoids with antioxidant properties.
- Vitamin E — An oil-soluble antioxidant that helps protect the blend from oxidation.
