I am a beauty therapist and have been using ARK products in my salon & on myself for just over a year now. I love this product and have been using it once a week (twice when I'm really good). I like to leave it on overnight for an extra special boost. My skin looks and feels amazing in the morning. I've got a toddler and a preschooler as well as running my own beauty business so life is pretty hectic and tiring - thankfully it doesn't show on my face!
