The NuFountain difference
A gentler dose, still fresh and fully active
Starting lower is the smart way to introduce vitamin C — but a low strength that's also gone stale barely does anything. We blend your C10 to order and hand-date it, so a gentle 10% still delivers real, active vitamin C to your skin.
Typical shelf serum
- Mixed weeks or months before you buy it
- No way to know how old the vitamin C really is
- Potency quietly drops as it oxidizes
- Often padded with fillers and fragrance
NuFountain C10 Gentle 3-Pack
- Blended the day your order ships
- Hand-dated so you see exactly how fresh it is
- A gentle 10% that's still fully active
- Short, transparent ingredient list — nothing you don't need
What it does
An easy introduction to vitamin C
All the core benefits of vitamin C, dialed to a strength sensitive skin can live with daily.
Gentle enough for daily use
At 10%, most sensitive and reactive skin can use it every day with little to no tingle.
Brightens & smooths
Helps fade dullness and dark spots for a clearer, more even, more youthful glow.
Supports collagen
Vitamin C helps your skin build collagen, softening the look of fine lines over time.
What's inside
Simple, gentle, transparent
The same clean approach as our stronger serums, at a strength that's kind to sensitive skin.
10%
L-Ascorbic Acid
A gentler dose of the active form of vitamin C — effective for brightening and antioxidant support with less risk of stinging.
+
Glycerin
A soothing humectant that keeps the serum hydrating and comfortable.
Full ingredient list
Purified Water, 10% L-Ascorbic Acid, Magnesium Sulfate, Glycerin.
What to expect
Real results run on consistency
Even a gentle serum rewards consistency. Here's an honest timeline — results vary, and daily sunscreen protects your progress.
Weeks 1–2
Comfortable start
Skin adjusts easily and often already looks a touch brighter and smoother.
Weeks 4–6
Brighter tone
Dullness fades and skin looks clearer with steady daily use.
Weeks 8–12
Ready to level up
Many people graduate to our C20 once their skin is comfortable with daily vitamin C.
How to use
Four gentle steps
1
Cleanse
Start with clean, dry skin.
2
Apply 5–6 drops
Pat gently over the face and neck. Little to no tingle at this strength.
3
Let it absorb
Give it a minute to dry before your next step.
4
Moisturize + SPF
Follow with moisturizer, and always sunscreen in the morning.
Perfect for beginners. You can usually use C10 daily right away, but patch test first if your skin is very reactive. Keep the cap tight and store cool and dark — refrigerate unopened bottles. If the serum turns deep amber, it's oxidized and time for a fresh one.
Protect your results
Vitamin C works best with daily sunscreen
We don't sell sunscreen — so this isn't an upsell. It's the single most important thing you can do to protect what your serum is working toward, and it's worth getting right.
Without daily SPF
- UV light breaks vitamin C down and undoes your brightening
- New dark spots and sun damage keep forming
- Collagen breakdown speeds up, so fine lines deepen
- Your serum is left fighting an uphill battle
Vitamin C + daily SPF
- Locks in and protects your brightening progress
- Helps stop new dark spots before they start
- Guards the collagen your serum is helping build
- The two work together for visibly better results
What to look for in a sunscreen
Broad-spectrum
Look for the words “broad-spectrum” — it protects against both UVA (aging) and UVB (burning) rays.
SPF 30 or higher
SPF 30 blocks about 97% of UVB. Go higher if you're outdoors a lot — just don't drop below 30.
Every single morning
Apply as the last step of your morning routine, over your serum. Reapply every two hours in direct sun.
A texture you'll wear
Mineral (zinc oxide, titanium dioxide) or a modern chemical filter — pick one that feels good so you use it daily.

Questions, answered
Will all three bottles stay fresh?
Yes. Each bottle is blended fresh and hand-dated, and unopened bottles keep their potency for months in the refrigerator. Open one at a time and use it within about three months of opening.
Who is C10 best for?
Anyone with sensitive or reactive skin, or anyone brand-new to vitamin C. The lower 10% strength gives you real brightening and antioxidant benefits with much less chance of tingling or irritation.
Should I start with C10 or go straight to C20?
If your skin is sensitive or you've never used vitamin C, start with C10. Once your skin is comfortable using it daily, you can graduate to our 20% C20 for a stronger dose.
Will I still see results at 10%?
Yes — because it's blended fresh and fully active, a gentle 10% still brightens, supports collagen and helps target dark spots. It just works a little more gradually than 20%.
How should I store it, and how long does it last?
Keep the cap closed and store in a cool, dark spot; refrigerate unopened bottles to extend freshness. Once opened, use it within about three months. A deep amber color is your signal it has oxidized and it's time for a fresh bottle.
What if it doesn't work for me?
You're covered by our 30-day money-back guarantee — no need to return the bottle. If you're not happy, contact us for a full refund.
Zero risk
