Morning use or don’t bother. That’s it.
Vitamin C burns off in sunlight if you layer it wrong — but this one actually stabilizes. I’ve had bottles go brown on me in two weeks. This one lasted three months on my bathroom counter like a champ.

CellFusion C Advanced Serum, $85 for 1oz. The claim that got me: “circadian-aligned delivery system” — which is fancy-speak for “works with your skin’s clock, not against it.”
THD Ascorbate (not L-Ascorbic)
Stable. No fridge required. Doesn’t sting like the cheap stuff.
Time-Release Spheres
They burst in waves over 8 hours — not all at once like a frat party.
pH 5.5 Balanced
Won’t wreck your barrier like those acidic vitamin Cs that leave you peeling.

Three actives that don’t hate each other — rare in skincare. The formula is built for morning use specifically, which is smarter than 90% of vitamin Cs on the market.
- THD Ascorbate: Brightens without the burn — absorbs in 10 seconds flat
- Ferulic Acid: Doubles the C’s power, stops it from oxidizing on your face
- Vitamin E: Locks moisture in so you don’t get that tight, papery feeling
- Hyaluronic Acid: Low molecular weight — actually penetrates, doesn’t just sit on top

Watery-gel. Smells like a fresh orange peel — no fake candy scent. Disappears into skin so fast I thought I forgot to apply it. Zero tackiness under SPF.
Week 3 hit and my forehead lines looked… softer? Not gone. But my makeup stopped settling into them. That’s when I stopped being skeptical.

Dark spots from last summer’s breakout session — 40% lighter in 4 weeks. Pores didn’t shrink (nothing does) but they looked less… crater-y. Texture evened out around week 5.

AM use only. Skip the PM retinol fight entirely. This is the vitamin C your derm actually meant when they said “use it in the morning.”
