    • Massage 1-2 pumps into clean skin before applying your favorite moisturizer. Use AM or PM—or whenever your skin needs an extra boost of hydration.

    Q: What is the benefit of Hyaluronic Acid?

    A: Hyaluronic Acid is a powerful hydrator that helps attract moisture to the skin to keep it looking plump and replenished. It can hold up to 1,000x its weight in water, making it incredibly effective for locking in moisture and helping skin appear more smooth and bouncy.


    Q: How does Forest Water compare to other Ursa Major serums? Can I combine Forest Water with other Ursa Major serums?

    A: Our Forest Water is designed to quench your skin’s thirst! While our dynamic lineup targets brightening and evening your complexion, Forest Water complements the range as a true hydration powerhouse.


    Yes! We recommend starting slow—use a small amount of product and give each layer time to fully absorb before applying more. Everyone’s skin is different, so it’s helpful to experiment and see what works best for you. For optimal results, layer your skincare in order of consistency, starting with the thinnest product and working your way to thicker creams and oils.


    Q: Can I use Forest Water under or around my eyes?

    A: Avoid direct contact with the eyes. While the product is formulated with gentle ingredients suitable for most skin types, we suggest applying it around the eye area carefully, avoiding the eyelids and immediate eye contour. Always perform a patch test prior to applying any new product near sensitive areas to ensure compatibility with your skin.


    Q: Can I use Forest Water both day and night?

    A: Absolutely! Forest Water is versatile enough to be used both morning and night. Its lightweight texture makes a perfect daytime hydrator and its replenishing properties also make it ideal for nighttime use to restore moisture while you sleep.


    Q: Can I use Forest Water under makeup and SPF?

    A: Yes! Forest Water is a great base under makeup and SPF. It hydrates and preps your skin, creating a smooth canvas for makeup, while also giving you an extra layer of moisture. Let it sit for a moment before applying and you’re all set!


    Q: Is the serum safe for sensitive skin?

    A: Our serum is crafted with sensitive skin in mind, but we always recommend conducting a patch test before use, especially if you have highly sensitive skin.


    Q: Is Forest Water pregnancy safe?

    A: Ensuring the safety of our ingredients is our top priority at Ursa Major. While this product does not contain any ingredients that are commonly avoided during pregnancy, we always recommend checking in with your healthcare provider about ingredient lists.


    Q: What is the aroma?

    A: A soft, grounding aroma with warm, woodsy notes of Fir, Birch and Bergamot.


    Q: How do I recycle this product?

    A: When you finish the product, simply rinse out the glass container and recycle it at home. However, the plastic pump is made from 50% post-consumer plastic and isn’t widely recyclable at this time.

      like dew drops on a mossy log

      I'm loving Forest Water - it is now officially my favorite Ursa Major serum. As someone who is very picky about scents, this is absolutely perfect: subtle, natural and refreshing. It actually smells like dew drops on a mossy log in the forest, in the best possible way! It's silky and light and goes on smoothly. It feels so fresh and hydrating and it seems to make the fine lines around my mouth less noticeable immediately upon application.

      Silky and Cooling Hydration

      This concoction is such a treat to put on the face; it melts into the skin quickly and feels cooling and protective right after washing my face. Before receiving this product, I was dealing with a bout of what I think was/is a form of Rosacea, and I feel like once I incorporated using this product into my facial routine, it helped bring down the inflammation!

      Just what my dry skin needed!

      I've suffered from dry skin my whole life, but as I inch closer to 50, it's gotten worse. Forest Water Hyaluronic Serum has been a game changer. It pumps my skin and makes it feel hydrated. It stood up to plane travel and a week spent in the sun and deserts of Arizona. My skin glowed and the dryness was gone!

      Love this hydrating serum!

      I love this serum! - It's perfectly light and sinks into my skin easily without leaving it feeling sticky. It's a great serum for layering with other serums and even better I've paired it with the Ursa Major mineral polish to help let it truly sink in. My skin feels nicely hydrated and it's easy to use morning or night. This is a perfect core product to keep in rotation!

      LOVE this new serum, it's a game changer!

      This serum feels like a drink of water for my skin, I actually look forward to using it everyday (twice a day!). I have sensitive skin and I've had no reaction whatsoever, it just leaves my skin hydrated and happy and it has a very light "woodsy" fragrance that I love..

      Ursa Major has become my FAVORITE skincare line, I now use the entire line and my 56 year old skin has never been happier!
