Surprising
In a trial of 132 breast cancer patients, olive oil cream prevented severe skin reactions as well as a prescription steroid — cutting the rate of grade 3 dermatitis from 61% to 27.9%.
This suggests that a simple kitchen staple might offer a non-drug alternative for a specific, harsh side effect of radiotherapy — but the result comes from a single study in a clinical population, so it doesn't yet apply to everyday skin care or other types of dermatitis.
Researchers compared a olive oil cream against both a topical steroid (betamethasone) and an unmedicated cream base in women undergoing radiation for breast cancer. The olive oil cream lowered the odds of developing the most severe (grade 3) skin damage by more than half compared to the plain cream, and performed on par with the steroid — though the study found no benefit in delaying when milder skin reactions first appeared.
Where this fits in the evidence
This is among the first studies we've indexed on Olive Oil for Reduced Incidence of Dermatitis — treat it as an early signal until more research accumulates.
