Skin Up Logical Tan is the new active ingredient of Phil Pharma for tanning and moisturizing the skin. The key elements of Logical Tan are Hyaluronic Acid and DHA, an extract of sugar cane that can color our skin in a completely natural way. A tan for every skin. Skin Up Logical Tan offers a tan completely identical to that obtained from exposure to the sun. But we always start with a basic skin color, which can be more or less clear depending on the person. To offer a tan quite similar to the natural one, Phil Pharma has devised 2 different combinations of Logical Tan: the Light, for lighter skins, and the Dark, for those who have naturally darker skin.
