This tailor-made tanning system works with your skincare routine by transforming your favorite moisturizer, serum, or oil into a custom self-tanner - resulting in 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. Apply more drops for a deeper end-result color. Choose your shade based on your skin-tone, not your desired end-result, and wash hands thoroughly after application.
