Ursa Major Mountain Glow Golden Serum, 1 fl oz

A rich oil-serum hybrid that melts from a cream-like texture into a dry-finish oil with the warmth of your skin — 44 botanical actives drawn from Vermont forests and global plant traditions, built around a base of coconut oil, jojoba, argan, and rosehip. The result: deep hydration, visible glow, and an extraordinary sensory experience that smells like a forested hillside after rain.

This serum is specifically suited to dry, dull, mature, and resilient skin that needs more than standard hydration. It is not the right fit for acne-prone or highly comedogenic-sensitive skin (coconut oil base), or for skin that reacts to complex botanical formulas. If you're building a glow routine and your skin drinks up rich plant-based formulas, this is GUSU's deepest nourishment pick.

Why people use it

• Delivers an immediate visible glow and dewy, plumped appearance from deep plant-oil nourishment of the barrier
• Phytosterols (plant-derived barrier lipids) reinforce the skin's natural lipid matrix — one of the most effective clean ingredients for barrier repair
• Black Tea + Mushroom ferment complex supports skin renewal and antioxidant protection
• 44 forest-derived botanicals including adaptogens, bark extracts, mushrooms, and lichen — a sensory ritual, not just a product
• B Corp certified, Plastic Negative — for every bottle sold, two plastic bottles are removed from the environment via rePurpose Global

What's inside

• Cocos Nucifera (Coconut) Oil + Argania Spinosa (Argan) Kernel Oil + Rosa Canina (Rosehip) Seed Oil – a three-oil foundation that delivers omega-3, omega-6, and beta-carotene (natural vitamin A precursor) from plants; forms the primary nourishing base
• Phytosterols – plant-derived lipids that are structurally similar to the cholesterol in your skin's barrier; evidence-backed for barrier lipid replenishment
• Cladonia Stellaris (Star-Tipped Lichen) Extract – an Arctic lichen extract with antioxidant activity; one of Ursa Major's hero forest ingredients, sourced sustainably
• Gleditsia Triacanthos (Honey Locust) Seed Extract – a polysaccharide-rich seed extract that provides humectant hydration and soothing film-forming properties on the skin surface
• Fomes Officinalis (Agarikon Mushroom) + Poria Cocos (Poria Mushroom) Polysaccharide – adaptogenic mushroom extracts traditionally used for immune support; in skincare, provide antioxidant and skin-soothing activity
• Saccharomyces/Xylinum/Black Tea Ferment (Kombucha) – a fermentation-derived active that provides skin-conditioning postbiotics and antioxidant compounds
• Vermont Forest Bark Complex – Black Spruce, Jack Pine, Yellow Birch, Silver Birch, Red Maple, Sugar Maple bark and sap extracts; antioxidant polyphenol-rich botanicals from the same forests that inspired the brand
• Populus Tremuloides (Golden Aspen) Bark Extract – a natural source of salicin (a BHA relative) and tannin polyphenols; supports mild cumulative brightening and antioxidant protection
• Sodium Hyaluronate – foundational surface hydration
• Hydrolyzed Viola Tricolor (Wild Pansy) Extract – a flower extract traditionally associated with calming visible redness and supporting an even complexion
• Fusanus Spicatus (Sandalwood) Wood Oil – source of the warm, subtle honeyed-wood botanical scent; natural origin, no synthetic fragrance
