Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A water- or solvent-based extract derived from the above-ground parts of Hemerocallis sempervirens, a perennial daylily species. The extract contains various plant compounds like flavonoids and phenolic acids that have antioxidant activity.
How it works
When applied to the skin, the antioxidant compounds in the extract can help neutralize free radicals—unstable molecules that can damage skin cells and accelerate signs of aging. It may also have mild soothing effects by calming minor surface inflammation.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without irritating sensitive skin, making it suitable for daily use in serums or moisturizers.
Soothing potential
May help reduce minor redness or irritation, offering a calming effect that complements other soothing ingredients.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so the real-world benefits are not yet fully proven.
Low typical concentration
Often used at low levels in formulas, meaning its impact may be subtle and not as powerful as more established antioxidants like vitamin C.
Best for
- Anyone looking for extra antioxidant support in their routine
- People with sensitive or reactive skin who want gentle protection
Use caution if
- Those with known allergies to daylilies or related plants (rare)
Usage tips
Safety summary
Considered safe for topical use with a low risk of irritation or allergic reaction. As with any plant extract, patch testing is recommended for those with very sensitive skin or plant allergies.
Research notes
Preliminary lab studies suggest antioxidant and anti-inflammatory activity, but clinical evidence in humans is sparse. More research is needed to confirm its effectiveness in skincare.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, with no specific restrictions beyond standard cosmetic ingredient regulations.
- Common uses
- Serums, Moisturizers, Toning Lotions
- Environmental note
- Daylilies are hardy, low-maintenance plants that can be grown without heavy pesticide use, making this extract relatively sustainable when sourced responsibly.
Good to know
- This extract is not the same as the more common daylily flower extract; it comes from the leaves and stems.
- It is often found in products marketed as 'natural' or 'botanical' due to its plant origin.
