Skincare’s Most Expensive Serum Just Got Dupable — C E Ferulic Patent Has Expired

SkinCeuticals C E Ferulic Patent Has Expired

Hot Dog Water Chic? Why Everyone’s Talking About SkinCeuticals’ Vitamin C Serum

As of now, other brands can legally dupe the $182 cult-favorite vitamin C serum, thanks to the expiration of its patent. What that means? A wave of copycats, more price points, and maybe fewer burnt garlic vibes.

“Yes but will it also smell like burnt garlic hot dogs?”
“Hot dog water is what I called it.”
“It’s the worst delivery system. Sunlight ruins it, but ok.”

The comments are going down in history as some of the funniest beauty commentary of the year — and also, kind of a warning label.

The Science: What Made It Iconic

The OG C E Ferulic combined 15% L-ascorbic acid (vitamin C), 1% vitamin E, and 0.5% ferulic acid — a cocktail that stabilizes antioxidants and boosts photoprotection.

That formula became iconic in clinical circles and editorial favorites lists alike — despite the smell and the $182 price tag.

What Happens Now?

L’Heir’s Take:

The memory of this serum may forever smell like garlic and regrets, but it’s also a reminder of how beauty legends age — and how science (and social media) shape their legacy.

Would you still use it? Or are you team “dupe it, but deodorize it”?
