Lemon EO is cold-pressed from the lemon rinds. It supports healthy pH level, it is uplifting and revitalizing. I take a drop in my water daily, it is detoxifying and even increases mental focus and clarity! I definitely need that! This is also in my Ageless Night Serum as well is in the “Allergy Trio”. Did I mention it takes a black sharpie marker off your wall??? Amazing!
