Ursa Major Brighten Up Vitamin C Serum (30ml)

A brightening serum that actually stays bright. Most Vitamin C formulas lose potency before you're halfway through the bottle - Brighten Up solves that with two highly stable forms of Vitamin C, Tetrahexyldecyl Ascorbate and Ascorbyl Glucoside, that maintain maximum potency from the first pump to the last. Together they target dullness, dark spots, and uneven tone, while Edelweiss Stem Cells deliver antioxidant protection, Organic Rose Hip adds a natural hit of skin-nourishing Vitamin C, and Golden Aspen Bark gently exfoliates to keep texture smooth and pores clear. Lightweight, silky, and finished with a fresh-squeezed citrus scent. Sunshine in a bottle.

Who's It For

Why MASC Recommends This

Vitamin C is one of the most researched brightening ingredients in skincare - and stability is everything. Brighten Up uses two forms that won't oxidise and lose efficacy halfway through the bottle, which means you're getting consistent results every single day. The formula is clean, the ingredient list is short and purposeful, and the fresh citrus scent makes it genuinely enjoyable to use every morning. Ursa Major is a certified B Corp and Plastic Negative brand - this is brightening done with intention.
