create accountAfter years of living in NYC and working in the beauty industry, Ursa Major co-founders Emily and Oliver made the move to beautiful Vermont. It wasn’t long before they were inspired to take everything they knew about big beauty (toxic ingredients, fear-mongering, and more), and flip it all on its head. Soon, Ursa Major was born: delightfully effective, forest-infused skincare essentials—made with zero harmful ingredients—so your skin and your spirit can truly thrive!

"My skin feels smoother, more moisturized, the scent is subtle, not greasy or sticky."
— Meghan F. (5/5)
"The cornerstone of my nightly ritual. Luxurious texture, absorbs quickly, doesn’t dry out my skin, and mitigates the effect of sun damage. I put it all over my face and décolletage and let a good night’s sleep do the rest."
— Chelsea T. (5/5)
"I am on my second container of this product and really think it's helping my skin and reducing the look of the dark spots. I realized the other day that they are not as dark as they were."
— Tina P. (5/5)
"Non irritating, not harsh, but feels effective and more easily handled by my skin that other retinals I've tried."
— Ellen B. (5/5)
"Been using this serum once a week and my skin has been tolerating it very well! I have very sensitive skin that is prone to irritation and flare ups, and so far I have no complaints! I'm fairly conservative with my usage, just one pump and once weekly :)"
— Emma H. (5/5)
"All of Ursa Major's serums feel great soaking into my skin. I'm not sure if the Lunar Bloom Retinal Serum works as intended. But it still feels great, doesn't make my face red, and makes me feel like I'm doing something nice for my face."
— Margaret S. (5/5)
"My skin feels smoother with fewer lines."
— Coleen G. (5/5)
"I was skeptical when you guys changed the branding but the product is still my favorite before I go to bed. The retinal does wonders for my skin and the smooth texture is fantastic to apply. This is the best serum that I have and it's not going anywhere anytime soon."
— Chuck H. (5/5)
"I have been using this alone each night. I worried that it might cause issues, since I have had them in the past with retinal products but this has caused no issues. I don't feel the need to follow with a moisturizer. Happy with this product."
— Carol M. (5/5)
