* Tea Tree Oil (Melaleuca alternifolia): In recent years it has become increasingly popular as an antimicrobial agent and has also been demonstrated to possess anti-inflammatory properties. Tea tree oil should be used with caution, however, as it has been associated with a wide variety of side effects including allergic contact dermatitis, systemic contact dermatitis, erythema, and systemic hypersensitivity reactions as well as conditions such as linear immunoglobulin A disease.
* Camphor Oil (Cinnamonum camphora) : Recently, camphor oil has been evaluated for its efficacy in treating the demodicoses that are frequently comorbid with rosacea. In a study by Morsy, marked reduction in the infestation density were noted following application of diluted camphor oil at concentrations of 20% to 25%. Caution is warranted with the use of camphor oil, however, as it is a known skin irritant.
