Humulus Lupulus (Hops) Extract is a plant-derived ingredient rich in polyphenols and flavonoids (such as xanthohumol) used in skincare for its antioxidant, anti-inflammatory, and antimicrobial properties. It is also valued for soothing and conditioning effects on the skin.
| Reported effect | How often | Notes |
|---|---|---|
Contact dermatitis / allergic skin reaction | Uncommon | Hops can act as a contact allergen, particularly in individuals sensitized through occupational exposure (e.g., brewery workers). |
Skin irritation or redness | Rare | Mild localized irritation possible, especially with concentrated extracts or sensitive skin. |
Cross-reactivity in those allergic to related plants | Rare | Hops belongs to the Cannabaceae family; sensitized individuals may react to related botanicals. |
Phytoestrogenic activity concerns | Very rare | Hops contains compounds with estrogen-like activity; topical relevance is minimal but noted in research. |
