Acne is the most prevalent chronic skin condition in the ages of puberty and adolescence, which manifests itself as either non-inflammatory (whitehead and blackhead comedones) or inflammatory (papule, cyst and nodule) lesions. Acne and its dermal impressions have psychological effects on suffering individuals. Clinically, acne is categorized into two groups: in the first group, the condition is mild to moderate and lesions are present only in the visage and no scarring exists. In the second group, the condition is usually moderate to severe and the lesions affect the trunk as well and scarring might be present. Causes of acne include: increase in sebum production, blockage of follicular duct, follicular hyperkeratinization, Propionibacterium acnes and inflammation. According to the results of various researches, ferula has antimicrobial and antifungal properties. According to the results of studies on laboratory animals, lavender has anti-inflammatory and analgesic properties. Furthermore, it has been topically used to treat acne and prevent scarring and spot formation in the visage and body. Lavender is one of the most valuable oils in treatment of acne. Lavender inhibits the bacteria responsible for skin infections, relieves skin, helps balance sebum production and prevent scarring.
