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

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!

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.

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.

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.

    Lasting moisture for extremely sensitive skin

    I have rosacea and react with either redness or acne to most serums. I was desperate to find a moisturizing product to help soothe my dry skin through the cold winter. This product hits the mark! Skin looks slightly dewy and no redness or acne. Skin looks and feels restored!
