Ursa Major Vitamin C Brightening Serum — 1 oz, Stable Ascorbic Acid Polypeptide, Gentle Vegan Formula

Ursa Major Brighten Up Vitamin C Serum is a lightweight, vegan treatment that visibly brightens, hydrates, and helps even skin tone using a stable ascorbic acid polypeptide formula.

This concentrated 1-ounce serum blends naturally derived Vitamin C with soothing and protective botanicals to refresh dull complexions without harsh additives. The gel-serum texture sinks in quickly, layering smoothly under moisturizers or acting as a solo corrective step in morning or evening routines. Formulated to avoid parabens, synthetic fragrances, sulfates, silicones, PEGs and other suspect chemicals, it’s designed for people who want results from cleaner ingredients.

How does this serum brighten and even skin tone?

The formula uses ascorbic acid polypeptide, a water-soluble Vitamin C derivative engineered for improved stability and skin compatibility. Rather than relying on strongly acidic vitamin C that can oxidize quickly, this preparation maintains potency longer and supports a more balanced appearance over time.

• Contains ascorbic acid polypeptide for sustained brightening action
• Rose hip provides natural hydration and nourishing fatty acids
• Edelweiss extract contributes antioxidant support
• Light gel-serum texture allows even layer and quick absorption

Will this work for sensitive or reactive skin?

The Brighten Up serum is formulated to be gentler than traditional, highly acidic Vitamin C serums while still delivering corrective benefits. It omits common irritants like synthetic fragrance and harsh solvents, making it a suitable option for many people with reactive skin; patch testing is still recommended.

• Fragrance-free and vegan formulation reduces irritation risk
• Aspen bark helps soothe and calm skin during application
• Lower-risk Vitamin C derivative improves compatibility for sensitive skin
• Use sparingly at first to assess tolerance

How should I use Ursa Major Brighten Up in my skincare routine?

Apply a few drops to cleansed, dry skin once or twice daily, then follow with your moisturizer and sunscreen in the morning. The serum layers well beneath heavier creams or makeup and can be used alone for a featherweight feel when you prefer minimal steps.

• Morning: cleanse, apply 2–3 drops, moisturize, then sunscreen
• Evening: cleanse, apply serum, follow with night cream if desired
• Layer under oils or creams for extra hydration without pilling
• Introduce gradually if combining with active acids or retinoids

What ingredients make this serum clean and effective?

The Brighten Up formula balances effective actives with botanical support while avoiding a long list of suspect chemicals. It pairs a durable Vitamin C form with hydrating and protective extracts to support smoother, more luminous-looking skin.

• Ascorbic acid polypeptide — stable, water-soluble Vitamin C
• Rose hip — hydrates and conditions skin
• Aspen bark — soothing botanical extract
• Edelweiss — antioxidant protection from alpine plant

Who is this for? Ursa Major Brighten Up is best suited for people seeking a cleaner, non-irritating Vitamin C step to brighten and hydrate their complexion. It appeals to vegans and anyone avoiding parabens, synthetic fragrances, sulfates, silicones, and other common additives, and works well for both women and men who want a fast-absorbing daily corrective serum that layers easily with other skincare products.
