  • 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! Our dynamic serum lineup targets a range of concerns from fine lines, to firming, to brightening, and you can think of Forest Water as the true hydration powerhouse.


    And, yes! You can absolutely use Forest Water with our other serums. We recommend giving each layer time to fully absorb before applying more. For optimal results, layer your skincare products in order of consistency, starting with the thinnest product and working your way to thicker creams and oils. Everyone’s skin is different, so it’s helpful to experiment and see what works best for you.


    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.

      Hydration You Can See and Feel

      I receive this product for free in exchange for a review, but I've been purchasing (and obsessing over) other Ursa Major products for close to two years now. I have very sensitive skin that gets dry and irritated during Vermont's long cold winters and this serum helped revive my skin as spring arrived. I could immediately feel my skin plump up after the first use and my skin has only looked better with each use. I will be reaching for this year round!

      Does what it says!

      I'm skeptical of anything that says it will make my skin "plump" or "firm," but this serum truly does! I saw immediate results after one day, and now have been using it for two weeks, and my skin still looks awesome. This is my new go-to serum, for sure! Plus, it smells nice =)

      Effective and fast-absorbing hydration

      I was thrilled to receive this product for free in exchange for a review, as I've been purchasing other Ursa Major products for awhile now and enjoying them very much.

      Hydration is a constant issue for my skin, because I live at altitude most of the time (~6k feet), and my hobbies include scuba diving, skiing and mountain biking. That means my already dry skin is exposed to dry mountain air, frigid salt water, lots of sun, and general neglect on a regular basis. I'm also in my mid-30s, so I can't get away with the neglect anymore, but I want to consume responsibly-produced products that are good for me and the planet, thus the exploration of Ursa Major products.

      For the past few weeks, I've been using the Forest Water Hyaluronic Serum 1-2x per day after cleansing and using toner. The scent is very nice, but not overwhelming. The first thing I noticed about this product is that is absorbs very quickly, but leaves my skin feeling noticeably more hydrated without any oiliness. I've noticed a decrease in fine lines, and my skin generally looks more healthy. I haven't had any breakouts or negative reactions to this product, which is important to me given that in addition to being very dry, my skin is quite sensitive. I would compare the results of this product to what I generally expect from a sheet mask, but without the 20 minutes or so of sitting with the mask on, which is great for me since I live a busy life.

      Overall, I'm very pleased with the product, and plan to…
