This tailor-made tanning system works with your skincare routine by transforming your favorite moisturizer, serum, or oil into a custom self-tanner - creating a natural-looking, radiant glow. **How To Use**: Mix 1-12 drops of self-tanner into your moisturizer, serum, or oil in the palm of your hand and apply evenly to the face. Choose your shade based on your skin-tone, not your desired end-result; additional drops will create a deeper end-result color.
