Yellow bottle of Ursa Major Mountain Glow Serum on a white background
Mountain Glow Serum

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.

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?  

Mountain Glow’s unique cream-to-oil texture melts into your skin on contact for instant absorption and radiance. Use it morning, night, or both, either as the first step before your favorite moisturizer, or in place of a face oil for an extra glowy finish.

Is this suitable for oily skin?  

Yes! We understand there may be some hesitation around using an oil-based product if you have oily, combo, or acne-prone skin; however, the Jojoba and Rosehip oils in Mountain Glow closely resemble our skin’s natural oils, helping balance sebum, without clogging pores.

Is this product pregnancy-safe?  

Mountain Glow Serum does not contain any ingredients that are commonly avoided during pregnancy, like vitamin A or high doses (+2%) of salicylic acid. That said, we always recommend checking in with your healthcare provider about ingredient lists and any new products during pregnancy.

Does this contain fragrance?  

Mountain Glow has a soft honeyed 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.

    The packaging is amazing - I was able to get every last drop out via the pump, didnt even have to open the top. Seems like a small thing but it shows how much they care about the end product in its entirety. Will be re-buying.
