Ingredient review
Spilanthes Leaf Extract
INCI: Spilanthes Acmella Leaf Extract
A plant extract that may temporarily tighten and smooth skin, but research is limited and effects are subtle.
In plain English
Spilanthes leaf extract comes from a flowering plant sometimes called the toothache plant because chewing its leaves numbs the mouth. In skincare, it's used for a temporary tightening or firming sensation on the skin, similar to a mild, natural Botox-like effect. However, this effect is not permanent and varies from person to person. The extract is generally gentle and unlikely to clog pores or cause irritation for most people.

What it is
Spilanthes acmella leaf extract is a botanical ingredient derived from the leaves of the Spilanthes acmella plant, a member of the sunflower family. It contains active compounds like spilanthol, which is known for its numbing and muscle-relaxing properties.
How it works
In cosmetic products, spilanthes extract is thought to work by temporarily relaxing facial muscles when applied topically, which can reduce the appearance of fine lines and wrinkles. It may also stimulate collagen production and improve skin elasticity, though these effects are less well-documented.
Pros
Gentle firming effect
Provides a temporary tightening sensation that can make skin look smoother, especially around the eyes and mouth, without irritation.
Natural origin
Derived from a plant source, making it appealing for those seeking botanical alternatives to synthetic firming agents.
Cons and cautions
Temporary results
The firming effect wears off within hours, so it requires consistent daily application to maintain any visible benefit.
Limited research
Most evidence comes from small studies or anecdotal reports; large-scale clinical trials confirming its efficacy and safety are lacking.
Best for
- Individuals looking for a gentle, plant-based option to temporarily soften fine lines
- Those with sensitive skin who cannot tolerate stronger anti-aging actives
- People interested in natural or botanical skincare ingredients
Use caution if
- Anyone expecting dramatic, long-lasting wrinkle reduction similar to injectables
- Individuals with known allergies to plants in the Asteraceae family (e.g., daisies, ragweed)
