You’re wasting it at night. Seriously. The whole point of vitamin C is to act as a sacrificial shield against your day.
It neutralizes free radicals from pollution and UV *before* they can damage collagen. At night, there’s nothing to fight. You’re just letting it oxidize on your shelf.
This is SkinCeuticals C E Ferulic. It’s $182. I tried it because derms swear its specific 15% L-ascorbic acid formula is the only one proven to penetrate.
The Golden Standard
The pH is precisely 3.5 for actual efficacy.
The Sticky Part
Yes, it feels like thin maple syrup. For about 45 seconds.
The Smell
Like hot dog water. No one talks about this enough. You get used to it.

It’s not just vitamin C. It’s a trio. The vitamin E and ferulic acid aren’t just extras—they recycle the C, making it last 8x longer on your skin.
- 15% L-ascorbic acid: The only form that sinks in deep enough to rebuild collagen
- 1% Vitamin E: Stabilizes the C, boosts photoprotection
- 0.5% Ferulic Acid: Doubles the formula’s free radical defense
- Pure Vitamin C: Unstable on its own—this combo fixes that.

Warm 4 drops in your palms. Pat, don’t rub. It’s slick, then it’s gone—dries to a faint, tacky film. That’s your protective layer.
By week two, my foundation stopped oxidizing. My skin looked brighter by noon, not dull. The surprise? It didn’t pill under sunscreen. A miracle.
My existing hyperpigmentation faded faster. New acne marks vanished in days, not weeks. Zero effect on deep wrinkles—that’s not its job.
It’s overpriced, smells weird, and is non-negotiable for morning use. The only serum I’ve seen deliver on the “antioxidant shield” promise.
