You don’t wear vitamin C at night. That’s like putting on sunscreen to go to bed.
Its entire job is to sacrifice itself to free radicals from UV and pollution — a shield you build before you leave the house. At night, there’s nothing to fight.
This is SkinCeuticals C E Ferulic. $182 for 1 oz. I tried it because derms swear the patented 15% L-ascorbic acid formula is the only one proven to penetrate.
The Smell
Hot dog water. No, really. It fades fast.
The Feel
Watery texture — absorbs in 15 seconds, leaves a slight tack.
The Bottle
Amber glass with a dropper. It oxidizes if you’re slow — turns dark yellow.

It’s not just vitamin C. It’s a trio. C neutralizes free radicals, E doubles C’s efficacy, and ferulic acid stabilizes both while boosting protection.
- 15% L-ascorbic acid: The only form with decades of data for photoprotection
- 1% Vitamin E: Repairs and reinforces the skin barrier
- 0.5% Ferulic Acid: Boosts stability and doubles UV protection

Apply to clean, dry skin. It tingles for a minute — that’s the acid working. The tacky layer is your primer. Let it dry completely before sunscreen.
By week two, my foundation stopped oxidizing (turning orange) by noon. A legit, unexpected win for makeup wearers.

My skin looked more “even” by week 4 — not radically brighter, just less tired. Zero new dark spots all summer. Did not magically erase old ones.
It’s expensive sunscreen insurance. Not a miracle worker, but the most credible daytime defense you can buy.
