Pros
- Dries noticeably fast, with multiple people saying they could apply a second coat quickly.
- Goes on smooth and even; two thin coats are enough for full, opaque coverage.
- Smell is present but milder than conventional polish.
- Lasted about a week for several people, with wear showing more as grow-out than heavy chipping.
Cons
- Bottles are small relative to the price.
- Durability is inconsistent; a few people saw chipping within the first day, especially with heavy hand use.
- One person found the brush lumpy and tubular, making it impossible to get a streak-free application.
- Conventional nail polish (not gel, not peel-off) with a crème finish in a deep burnt umber shade. The base of the formula is plant-derived, sourced from sugarcane, cassava, cotton, and corn rather than fully petroleum-based solvents.
- Most non-toxic nail polishes reformulate by removing certain chemicals. Sienna's formula also excludes nano-particles, which is uncommon in the category and relates to how pigments are milled and processed.
- A dedicated lab with 40 nail polish researchers develops the formulas, so this isn't a white-label product with custom branding on top. The bottles are finished with sustainably sourced timber caps.
- Two to three coats for full coverage, paired with a base coat and top coat (sold separately). It's a standard air-dry formula, not UV-cured.
- Started at the Byron Bay community markets in 2013 with 13 shades and now sold in 20 countries. The brand still operates out of Byron Bay, Australia, which shapes its emphasis on plant-based sourcing and eco-conscious production.
