I'm new to aromatherapy, having tried so many high street brands! None of them work for me, as I have sensitive, combination skin. I'm also trying to heal existing acne as well as reduce scars, so I am thinking of buying tea tree or lavender oil to add to sweet almond oil. I wanted to try the natural approach so I wasn't overloading my skin with chemicals. Does aromatherapy work, in particular lavender oil? Thanks x
