Why It's Special

Lightens & brightens

If you’ve soaked up a little too much sun over the years, it might be time for a Vitamin C serum. Ours includes a concentrated form of Vitamin C, along other powerhouse natural actives that brighten dull-looking skin and lighten stubborn dark spots.

Balances tone & texture

Active ingredients like Aspen Bark (a natural source of BHA) add a conditioning and gently renewing effect, while Aloe and Rose soothe skin and reduce redness. You’ll start to notice smooth, even, and all-around radiant skin.

Effective to the last drop

Not all Vitamin C serums are created equal. In fact, most lose their potency by the time they get to your shelf. Ours features a highly stable form of Vitamin C, to ensure peak freshness and potency over time.


A step you’ll never skip

Its silky, featherweight texture (and heavenly scent) makes it easy to work into your routine. Add it as a hydrating layer under SPF in the morning, beneath your heavier moisturizer at night, or both. Whatever works best for your skin.

Apply 1 pump to clean, dry skin. Use alone as a lightweight moisturizer or layer beneath your favorite face lotion, sunscreen or night cream. 

Q: Is Vitamin C, Mountain Glow, or Lunar Bloom (or all three) the serum for me?

A: Good question! Whether you use one, two, or all three serums is totally up to your own skincare goals and routine preferences.


Brighten Up Vitamin C Serum is our lightweight and layerable brightening treatment, designed to target hyperpigmentation, even out skin tone, and give dull skin that extra boost of radiance.


Mountain Glow Golden Serum is our do-it-all super-serum designed to deeply nourish and restore lasting moisture to your skin, combat visible signs of aging, and reveal a healthy, dewy glow.


For PM use only, Lunar Bloom Retinal Serum is a supercharged powerhouse that helps rewind the look of fine lines and wrinkles while you sleep. It works by promoting renewal and boosting collagen in mature or lackluster skin. 


If you opt for using all three serums, our recommendation would be to use Vitamin C in the morning and layer Mountain Glow over Lunar Bloom at night, or alternate between these two serums every other night.


If you want more help with your decision, check out our Skincare Quiz or drop us a message. 


Q: How and when do I use this product? 

A: For best brightening results and combating of free radical damage, apply this serum to clean, dry skin before moisturizing. 


Pair Vitamin C with Force Field SPF 30 before heading outdoors to treat the skin you’re in, while protecting it against future harm.


Q: Is this product suitable for sensitive skin?

A: Because we decided to go just slightly below the maximum ingredient dosage, our Vitamin C Serum retains all the power without risking unnecessary irritation. Of course, as with any product, if you have extra-sensitive skin, we might recommend doing a patch test to check before applying to the full face. 


Unlike other Vitamin C serums, Brighten Up Vitamin C does not cause photo-senstivity, but we absolutely encourage pairing with an SPF before heading outdoors!


Q: What makes this formula so potent?

A: We formulated our Vitamin C Serum with ascorbic acid polypeptide, a version of Vitamin C that retains its potency far longer than traditional formulas. We included it at a concentration that's less likely to cause unnecessary irritation, while maintaining efficacy.


Q: Is there any chance of oxidation?

A: We’ve conducted rigorous testing of this product efficiency and ingredient stability prior to launch to ensure that your serum is totally fresh when it reaches your hand. This serum is protected against any potential degradation thanks to special UV-coated glass packaging. We also chose a stabilized version of Vitamin C (ascorbic acid/orange/citrus limon/citrus aurantifolia polypeptide) and added additional antioxidants like rosemary extract to further delay oxidation.


Q: How do I recycle this product? 

A: When you run out, just give the glass container a rinse and recycle it at home. The plastic pump is mixed material and cannot be recycled at this time. 


Q: What is the aroma?

A: Fresh-squeezed citrus topped with herbaceous rose hip and sour rose. Due to the natural sourcing of our Vitamin C ingredients, some variation in scent from batch to batch is normal and can be expected.

    Vitamin C Serum review

    I use several of the Ursa Major products daily so it is difficult to definitively describe how the Vitamin C serum has improved my skin. Overall, I am beyond thrilled! I have always taken good care of my skin but noticed a year or so ago that I needed to up my game. At age 64 I am frequently told I appear to be in my late 40s or early 50s. My skin tone and skin firmness have greatly improved. Thank you! I’m a loyal customer!!
