Ursa Major Forest Water Hyaluronic Serum (30ml)

Hydration, taken seriously. Forest Water is a lightweight serum built around a multi-depth moisture system - Hyaluronic Acid draws water into the skin, Tremella Mushroom holds onto it (up to 500 times its weight in water), and Beech Tree Extract and Sequoia Leaf Extract lock it all in for lasting plumpness and firmness. Lupine Peptides support the skin barrier and help smooth the appearance of fine lines, while forest-sourced botanicals round out a formula that's as grounded as it is effective. Layers effortlessly under Moisturizer with a nearly weightless finish. The scent is a soft, woodsy whisper of Fir, Birch, and Bergamot - present but never pushy.

Who's It For

Anyone whose skin needs a serious drink of water. Particularly well-suited to dry, dehydrated, or dull skin, or anyone looking to add a dedicated hydration step to their routine. Lightweight enough for oily and combination skin types too. Works morning and night under Moisturizer, and pairs well with other serums for a hydration boost.

Why MASC Recommends This

A hyaluronic acid serum is one of the highest-impact additions you can make to a daily routine, and Forest Water builds on that foundation with a full cast of forest-sourced hydrators that most formulas don't bother with. Tremella Mushroom, Beech Tree, and Sequoia Leaf are doing serious work here alongside the Hyaluronic Acid - this isn't a one-trick formula. Ursa Major is a certified B Corp and Plastic Negative brand, and Forest Water reflects that commitment to clean, effective ingredients with real results behind them.
