Ingredient review
Chelidonine
INCI: CHELIDONINE
Chelidonine is a plant alkaloid with potential soothing effects, but its use in cosmetics is rare and lacks strong safety data.
In plain English
Chelidonine is a compound found in the greater celandine plant. In skincare, it's sometimes added to products meant to calm irritated skin, but it's not a common or well-studied ingredient. Because it's an alkaloid, it can be potent, and there isn't enough research to confirm it's safe for regular use on skin. Most products use it in very tiny amounts, if at all.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Chelidonine.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

What it is
Chelidonine is a benzophenanthridine alkaloid extracted from the greater celandine plant (Chelidonium majus). It has a long history in folk medicine but limited modern cosmetic use.
How it works
In cosmetic formulations, chelidonine is thought to interact with certain skin receptors to reduce signs of irritation, though the exact mechanism is not well understood. It is typically used at very low concentrations to minimize potential toxicity.
Pros
Natural origin
Derived from a plant source, appealing to those seeking botanical ingredients.
Potential soothing effect
May help reduce visible redness or irritation when used in very low concentrations.
Cons and cautions
Limited safety research
There are very few studies on chelidonine in skincare, making it hard to assess long-term safety.
Possible skin sensitivity
As an alkaloid, it may cause irritation or allergic reactions in some individuals, especially at higher concentrations.
Best for
- Those interested in plant-based skincare ingredients
- People with occasional skin sensitivity looking for natural soothing options
Use caution if
- Anyone with known allergies to poppy family plants (Papaveraceae)
- Pregnant or nursing individuals due to lack of safety data
Usage tips
Safety summary
Chelidonine has limited safety data for cosmetic use. It may cause skin sensitivity in some people, and its alkaloid nature warrants caution. More research is needed to confirm its safety profile.
Research notes
Research on chelidonine in cosmetics is sparse. Most studies focus on its pharmacological properties in internal medicine, not topical application. Evidence for its soothing effect is largely anecdotal.
Common label clues
- Typical concentration
- Very low (typically under 0.1%)
- Regulatory status
- Not specifically regulated as a cosmetic ingredient in most regions, but subject to general safety requirements for cosmetic ingredients.
- Common uses
- Soothing creams, Calming serums
- Environmental note
- Greater celandine is a common wild plant, but sustainable harvesting practices should be ensured to avoid overcollection.
Good to know
- Chelidonine is not a common ingredient in mainstream skincare; you'll most often find it in niche or herbal formulations.
- The greater celandine plant has a history of use in traditional medicine, but its topical safety is not well established.
