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.

How to Use

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 a hint of sour rose.

    Refreshing and cooling

    I love Brighten UP Vitamin C Serum. I use it primarily in the morning to give me a refreshing splash. I have been using it for at least a year now and look forward to using it for a long time. Only critique: I wish it had a little sight gauge on the side of the bottle so you could see the level of serum remaining. And it could come in a slightly larger bottle!

    Works extremely well

    I have dark spots and gave the Brighten Up Vitamin C Serum a try after I saw it on Instagram. I cannot believe how great this product makes my skin feel and look. My dark spots have noticeably diminished, not in an astonishing dramatic way, but I have noticed how much lighter and not so embarrassing they are. One thing I didn’t expect though was how the texture of my skin has improved. I used to have flaky, dry skin on my nose, this serum has eliminated that problem. I was so amazed by this improvement.

    I’m about half way through my second bottle. This second bottle has a different smell that’s not as pleasant as my first one, but the serum is still giving me great results. I am excited to see if my dark spots will improve with continued use.
