Ursa Major Mountain Glow Serum (30ml)

Forty-one clean plant actives, one extraordinary serum. Mountain Glow is Ursa Major's most complex formula - a honeyed, buttermilk-hued cream that melts into a silky oil on contact, delivering a concentrated hit of forest-sourced botanicals that work together to firm, brighten, and deeply nourish skin. Star-Tipped Lichen and Honey Locust Seed support the appearance of firmer, tighter skin and smooth fine lines. Moss Stem Cells restore barrier health and reduce visible signs of dryness. Golden Aspen Bark gently exfoliates for a radiant, lit-from-within glow. Wild Indigo Seed targets redness. Agarikon Mushroom tightens pores. The scent is warm and honeyed with notes of Linden Flower and fresh Birch - like golden hour in the forest. A few drops morning and night is all it takes.

Who's It For

Formulated for anyone looking to address multiple signs of ageing in a single step - fine lines, loss of firmness, dullness, uneven tone, and barrier damage. Particularly well-suited to normal, dry, and mature skin types, or anyone whose skin needs a serious replenishment boost. Lightweight enough to layer under Moisturizer without heaviness.
