Marin Skincare, the Portland, Maine brand, launched the Cider Donut Lip Treatment on 29 September 2026 as a limited-edition addition to its lip line, priced at $19.99. The brand says the product has been in development for two years. It uses Marin's Marine Glycoprotein formula with a scent the brand bases on an autumn orchard in New England.
What's New: Fall in a Tube
The scent is the new element. Marin describes Cider Donut as a sweet, nostalgic blend of freshly fried cider donuts, warm baked apples, cinnamon and sugar, and calls it "the magic of fall captured in a tube." It joins Marin's regular lineup:
- Unscented
- Mint
- Strawberry Rhubarb
- Blueberry French Toast
- Campfire S'mores
- Gingerbread
- A Tinted Lip Treatment in Cranberry
The Formula: Marine Glycoproteins
Cider Donut uses the same formula as the rest of the line. According to Marin, its founders are bioengineers who worked with lobster scientists to find a regenerative glycoprotein that lobsters use to regrow limbs. The brand says the protein also helps repair the skin barrier. Marin states that the ingredient is upcycled from lobster processing, using a byproduct that would otherwise be thrown away.
According to the brand, the lip treatment:
- Deeply hydrates and helps repair dry, weathered lips
- Soothes and protects lips when temperatures drop
- Soaks in while staying on for hours
- Uses a minimalist formula for sensitive skin, including lips prone to eczema or dermatitis
Because the glycoprotein comes from shellfish, Marin advises a patch test before use. This is especially important for anyone with a shellfish allergy.
How to Use
The brand gives these directions:
- Apply as needed during the day, whenever lips need hydration.
- Use it overnight as a lip mask.

A single tube costs $19.99. Cider Donut is also sold in bundles:
