You’re putting your vitamin C on at night? That’s like wearing a raincoat to bed.
Its main job is to neutralize free radicals from UV and pollution *before* they damage your skin. It’s a shield, not a repair crew. Using it at night wastes its superpower.
This is SkinCeuticals C E Ferulic. It’s $182. I tried it because every derm cites their specific, patented pH formula as the one that actually works.
Texture
Watery, oily-feeling serum that absorbs in under a minute.
Smell
Like hot dog water — a sign of pure L-ascorbic acid, they say.
Packaging
Opaque airless pump — crucial to prevent oxidation.
It’s not just vitamin C. It’s a trio that works together. The ferulic acid is the key — it makes the vitamins twice as stable and effective.
- 15% L-ascorbic acid: The antioxidant that quenches free radicals
- 1% Vitamin E: Repairs the skin barrier and boosts C
- 0.5% Ferulic Acid: The stabilizer that doubles protection
- pH of 3.0: Allows for actual penetration
It feels slick going on — a thin layer of cooking oil. Slight tingle. That weird smell fades fast, promise.
By week two, my sunscreen glided on smoother. The real surprise? My foundation stopped oxidizing and turning orange by noon.
My skin looked more “even” in a diffuse-light kind of way. No major brightening of old sun spots. But my skin felt tougher, less reactive.
It’s the most effective antioxidant serum I’ve used, but it’s not magic. It’s a brilliant, expensive bodyguard for your skin. Use it in the AM or don’t bother.
