You’re wasting it at night. Seriously.
The whole point is to create a shield against pollution and UV light — things you encounter during the day. Using it at night is like wearing sunscreen to bed.
The infamous C E Ferulic from SkinCeuticals. It’s $182. I tried it because their patented pH formula is the one all the derm studies use.
The Smell
Hot dog water. No one tells you that upfront.
The Feel
Absorbs in 30 seconds — leaves a dry, slightly tacky finish.
The Bottle
Opaque, airless pump. Crucial for keeping the vitamin C from oxidizing.

It’s not just vitamin C. It’s a specific 15% L-ascorbic acid cocktail at a pH under 3.5. That’s the magic window for skin penetration.
- 15% L-ascorbic acid: Neutralizes free radicals from UV light
- 1% Vitamin E: Boosts C’s antioxidant power by 4x
- 0.5% Ferulic Acid: Stabilizes the formula, doubles photoprotection
- Hyaluronic Acid: A hint of hydration
Watery, oily texture that disappears fast. The tackiness is real — you feel it until you put moisturizer over it.
By week three, my sunscreen glided on better. Zero pilling. Surprise: it didn’t irritate my sensitive spots at all.
My midday skin looked less tired. No new dark spots all summer. Did it erase old ones? No. But it definitely held the line.
It’s a brilliant, boring workhorse. Use it in the AM. Don’t expect miracles — expect a superior defense system.
