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.

Potent 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 includes a concentrated form of Vitamin C, along other powerhouse natural actives that brighten dull-looking skin and lighten stubborn dark spots.

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.

FAQ

Q: Should I use Vitamin C or Mountain Glow (or both)?

A: Good question! While both are serums at heart (vs. moisturizers), they do differ in their individual product design and intention. 


Our Vitamin C Serum is a specialized treatment product designed to lighten dark spots and hyperpigmentation, evening out skin tone and boosting overall radiance.


Mountain Glow is the techier, all-in-one super serum, focused on improving skin's appearance by combatting the visible signs of aging — especially wrinkles and sagging skin — while also boosting moisture and glow.


Depending on your skincare goals, you could use both serums together. You can layer Vitamin C underneath Mountain Glow, Vit C in the AM and Mountain Glow at night, or just use one of them, or mix them together! 


Q: How often / at what point in my routine do I use it?

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


Q: Is this safe 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 is the percentage / concentration of Vitamin C?

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. It's in there at a concentration of 1.5% (the maximum dose for this ingredient is 2.0%). We decided to go just slightly below that maximum to avoid any unnecessary irritation without sacrificing 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.

    It really works!

    After only a few days, I could see a lightening of sunspots on my jawline and the whole area was brighter. Thank you for such a great product that actually does what it’s advertised to do.
