It is a build up of these carotenoids in the skin that causes a colour change. The active carotenoid in these tanning pills is a substance called canthaxanthin. Once the tablet is taken the canthaxanthin is distributed through the body and is absorbed were it attaches itself to the subcutaneous layer that is found on the skin. This layer is darkened by the pigment and shows through the skin to give you a natural glow, it only takes 10 days for colour to show. Directions: Take two tanning tablets daily with a little sun exposure. Tablets should be taken after meals. Do not exceed dose.
