Acne vulgaris is a common skin condition that affects individuals of all ages. Conventional treatments for acne can have various side effects and may not be effective for all individuals. This study aimed to investigate the effect of rosemary extract in the treatment of acne vulgaris. The study was conducted on a group of individuals with acne vulgaris who were treated with rosemary essential oil in a gel product twice daily for a period of four weeks. The efficacy and safety of rosemary oil were evaluated by measuring the reduction in acne lesions and improvement in overall skin condition. The results of the study showed that rosemary oil was effective in reducing acne lesions and improving overall skin condition in individuals with acne vulgaris. The study also found that rosemary oil was well-tolerated and had minimal side effects. These findings suggest that rosemary extract could be a safe and effective natural alternative for managing acne vulgaris.
