What Is Bisabolol? Evidence for a Soothing Ingredient from Chamomile

Bisabolol, which you see near the end of cream ingredient lists, is a lightly scented, colourless, oily liquid. Its alpha form is also known as levomenol and is obtained from the essential oils of plants. It is presented as "reduces redness"; where does this claim come from?

Does it come from chamomile or from the tree?

Bisabolol was first obtained from German chamomile (Matricaria chamomilla). A review gives its share in the essential oil of this genus as 29-81%, and in the candeia tree (Eremanthus erythropappus) of South America as 66-91%. The candeia is cited as a species under threat, so the source is also debated in terms of sustainability. The name Bisabolol on the label does not state the source; you can learn whether it is plant-derived or synthetic only from the manufacturer.

Where is the evidence for its soothing effect?

The strong part is in the laboratory. Bisabolol reduced inflammatory signals such as TNF-α and IL-6 in immune cells, and reduced ear inflammation in mice. In old mice, a 0,5% and a 2% gel applied for 30 days increased barrier measurements and collagen content. These data explain why it is considered soothing, but they do not tell the size of the effect in human skin.

So the sentence "reduces redness" describes a possibility, not a proven result. No large study compares bisabolol alone with placebo, and the review authors call for clinical studies. If redness persists, do not try to handle it with a cream; see a dermatologist about the possibility of rosacea.

Allergy and absorption: Two things to watch in bisabolol

The independent expert panel's assessment considers bisabolol safe at its current use in cosmetics, and this view was maintained in the subsequent re-evaluation. Still, there are two points.

• Allergy: Rare but possible. A severe contact dermatitis case due to bisabolol in a face cream was published in 2024. A "soothing" label does not mean it will not react. So before applying it to the face, test it on the inner arm or elbow crease, for 7-10 days, twice a day. If you are allergic to chamomile, be careful; the relation between that allergy and bisabolol is not clear.
• Absorption: The same assessment warns that bisabolol may increase the penetration of other ingredients in the formula. So in products containing strong acids or retinoids, do not assume that a soothing ingredient means no irritation.

The EU cosmetics regulation's restricted substances annexes have no separate record for bisabolol. It is not surprising to find it in the same product as ingredients used as soothing agents, such as centella or panthenol.
