I've suffered from acne for years. I've gone to the dermatologist, tried proactive, X out, and a ton of other products. Personally my skin really seemed to improve after incorporating this into my skin care routine. Just apply the oil to the desired affected area and leave on over night. I used mine only at night, however it can be used more frequently. It does smell like tea tree oil (sorta minty) but I like the smell personally. This product wasn't too harsh or drying on my skin. Just helped clear up my breakouts and improve the clarity of my skin.
