Liquid gold for the face!
I have never left a review for a skincare product before, but feel the need to exclaim my appreciation. My skin is noticeably brighter and I have noticed a visible improvement in my old acne scars that have hung around for their dear life for years. It also feels light and clean. It's really the product that I didn't know I desperately needed, and I'm so glad I tried it.
Will Always Need This Serum
Maria F
This vitamin c serum is so unique with a milky smooth texture that instantly sinks into my skin. It gives a beautiful glow and hydrates while battling my dark spots from past breakouts. They are actually fading so quickly. My skin is so smooth already!
Best Vitamin C for sensitive skin
Kelly O.
This is my favorite vitamin C serum ever! I’ve used L ascorbic acid kinds for years and struggled with occasional redness and the bottle would always oxidize before I could finish it. This serum is amazing. Has a beautiful texture and finish, and I can see the difference already. My skin is much more even and bright.

Use after our First of All Cleanser. Follow with our Last But Not Least Moisturizer. 


If you're using our Sleep Tight Bakuchiol Serum, only use Next Up Vitamin C serum in the morning. 

Does this form of Vitamin C oxidize?
No. It's an oil-soluble form of Vitamin C that is highly stable. Unlike water-soluble L-ascorbic acid, this ingredient does not begin to degrade as soon as it comes into contact with light and air so it will be effective down to the last drop!
Can I use this day and night?
Yes! Because we use a gentler form of Vitamin C, you can use it both day and night. If you use our bakuchiol serum at night, we suggest only using our Next Up Vitamin C during the day.
How long will it take to see results?
As with all skincare, consistency is key! Many of our customers see results in a few days (especially for brightening!) but for more complex skin concerns (i.e. hyper-pigmentation), if you apply to your skin regularly you can expect to see results within four to six weeks.
Key Ingredients
TETRAHEXYLDECYL ASCORBATE The latest clinically-researched form of vitamin C is lipid-soluble so it can penetrate better than other forms of Vitamin C and is gentler on skin since it’s not an acid. It’s also very stable, so it won’t lose its efficacy over time.

VITAMIN E A powerful antioxidant that can be effective at reducing UV damage in skin, it helps nourish and protect from damage caused by free radicals.

GRAPESEED EXTRACT A great source of antioxidants that’s packed flavonoids which improve skin’s texture and help reverse or reduce the signs of aging.

What makes THD Ascorbate so special is not only is it 50X more effective than L-ascorbic acid, but it is also ultra-stable and non-irritating. It also is formulated with vitamin E, which on its own is a powerful antioxidant that can reduce skin damage - but when paired with vitamin C, they amplify each other’s antioxidant effects."
