Allium Cepa Bulb Extract

Allium cepa bulb extract is derived from onion bulbs and contains bioactive compounds including polyphenols and quercetin flavonoids. These are naturally occurring antioxidants that onions produce as part of their defensive chemistry.In skincare formulations, this extract functions as a skin conditioning agent. The antioxidant profile suggests it may help protect skin from oxidative stress, though the specific mechanisms by which these compounds benefit skin remain an area of ongoing research.

Reduces Irritation. Reduces Redness. For the Look of Scars

Onion bulbs contain sulphur-based compounds and flavonoid antioxidants that form when cells are damaged or processed. These bioactive molecules can help reduce oxidative stress — an imbalance of free radicals that contributes to skin ageing and inflammation.When applied topically in extract form, these compounds may help condition the skin barrier and provide antioxidant protection. However, the bioavailability of these compounds when applied to skin (rather than ingested) is not yet well established through clinical research.

Allium cepa bulb extract is typically found in concentrations below 0.1% in skincare products, often as one of several soothing or conditioning agents. Use as directed on your product; there is no specific guidance for optimising results beyond consistent application. If combining with other actives, observe your skin's response.

Onion extract is generally well-tolerated in skincare. Those with known onion sensitivity or allergy should avoid products containing this ingredient.
