After extensive research I have read that Licorice Extract is good for lightening redness on the cheeks area. I purchased a bottle and am not sure if the best way to use it is directly after toning and before moisturizing a.m and p.m? Or add it to products used a.m and p.m? Not sure, so any info is appreciated!I currently have been mixing it with 10 drops of extract and 5 drops Jojoba oil at night after Kassy's C-Serum. During the day just directly before moisturizer. Is it ok to use after the C-Serum????
