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.

    Hydrated Skin For Sure

    Love the wonderful feeling of hydration this serum offers. Once applied, I notice a bit of tightening to the skin that feels really good... a bit of an uplift if you will. My face drinks in the serum and brightens up as well. I use it in layering finishing with the Mountain Glow Serum.

    It's the real deal, worth every penny

    I am so impressed with the quality of this moisturizer. I only need a pea size and it covers my entire face.

    It stays on all day and makes my aging skin feel dewy again.

    I have very dry skin and now my foundation glides on.

    I am a devotee now.

    Forest water

    My skin looks better, less fine lines. Very happy with it. My only negative comment would be that it reminds me of nasal drainage in appearance
