After 15 years in the beauty world, I was fed up. Toxic ingredients, false promises, and over-priced products. So we moved to Vermont and started Ursa Major: skincare that uses clean, forest-infused ingredients for real results, without all the BS of traditional beauty.

    FAQs

    What is Hyaluronic Acid?  

    Hyaluronic Acid is a powerful hydrator that works by attracting water into your skin. It can hold up to 1,000x its own weight in water, making it incredibly effective at restoring moisture, so skin looks plump and replenished.

    Is this the serum for me?  

    Whether you use one, two, or all four of our serums is totally up to you and your skin needs!

    Forest Water Hyaluronic Serum is our go-to for deep hydration. It plumps skin, helping it appear firmer with fewer visible fine lines.

    Mountain Glow Serum is our go-to for an instant dewy boost. It restores moisture and supports collagen & barrier health, so skin looks youthful and firm.

    Brighten Up Vitamin C Serum is our go-to for brightening dull-looking skin. It targets stubborn dark spots and uneven texture and tone.

    Lunar Bloom Retinal Serum (for PM use only) is our go-to for dialing back the look of fine lines & wrinkles by promoting collagen production and skin renewal.

    Still need some help making a decision? Check out our Serum Quiz or send us a message.

    How and when do I use this product?  

    For best results, apply 1–2 pumps to clean, slightly damp skin. Use morning, night, or both—following with your favorite moisturizer to help seal in hydration.

    Is this safe for sensitive skin?  

    Though not tested for sensitive skin, we have designed our products to work for a variety of skin types and have heard awesome feedback from folks with sensitive, reactive skin. If you have extra-sensitive skin, we might recommend a patch test on the inner wrist before applying to the full face for extra precaution.

    Can I use this around my eyes?  

    While the product is formulated with gentle ingredients suitable for most skin types, we recommend applying it around the eye area carefully, avoiding direct contact with your eyes, eyelids, and immediate eye contour. If you have extra-sensitive skin, we suggest performing a patch test on the inner wrist before applying to the full face for extra precaution.

    Does this contain fragrance?  

    Forest Water has a subtle, woodsy aroma that comes entirely from real plant extracts—never synthetic fragrances.

    What if I don’t love it?  

    We totally understand that skincare is not one-size-fits-all and that everyone’s skin is unique. If you are not satisfied with your Ursa Major products, you may return your product for a full refund or store credit within 30 days of receiving your order.

    Do you offer free shipping?  

    We happily offer free standard shipping via DHL/USPS for all domestic orders $40+ placed on our website. Orders below $40 will ship via DHL/USPS for a flat $7 fee. 

    How do I start a return?  

    Super easy! Just head on over to our Returns Portal, where you’ll just need your order number (the one starting with UM) and your email address or zip code to get started.

      It’s effective!

      This serum seems to be helping my skin “shed” in a way that is subtle. I’m enjoying the process of attending to my skin in an advanced way in winter. The scent, the glide are so refreshing! Using Forest Water with Fortifying Gel Moisturizer hydrates and I love this bundle!

      A nice addition to quickly boost your skin’s hydration.

      I have seen a lot about hyaluronic acid on social media and based on my past experience with Ursa Major products decided I might as well go with a brand I trust unequivocally. This serum works well in the a.m. to give my skin an instant lift and a subtle healthy sheen.
