Three takes on fresh 20% vitamin C
Every serum in this pack is built on the same fresh-blended, hand-dated 20% L-ascorbic acid. What changes is the supporting cast — pure simplicity, added ferulic antioxidants, or niacinamide for dark spots — so you can feel the difference and settle on the one your skin loves.
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

Real results run on consistency
Try one at a time or rotate them. Here's an honest timeline for any 20% vitamin C — results vary, and daily sunscreen protects the progress.
First glow
Skin often looks brighter and smoother as it adjusts to daily vitamin C.
Find your favorite
Enough time to feel how each formula suits your skin and settle on a go-to.
Deeper change
Dark spots and fine lines typically show their most visible improvement here.
How to use the pack
Cleanse
Start with clean, dry skin.
Apply 5–6 drops
Use one serum at a time morning or night, or alternate. A mild tingle is normal.
Let it absorb
Give it a minute to dry before your next step.
Moisturize + SPF
Follow with moisturizer, and always sunscreen in the morning.
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.
