The St Moriz Advanced Pro collection brings you our most advanced range yet! Our Radiant Glow Tanning Serum will give you a made-to-measure fabulous glow with salon active ingredients. Designed to be mixed with your existing skincare, a few drops of our tanning serum will provide a radiantly glowing tan without losing the benefits of your skincare. Mix 3-6 drops of St Moriz Radiant Glow Tan Boosting Serum into your chosen skincare in the palm of your hand, and massage all over the face and neck. The self-tan will develop evenly without patchiness or visible marks, resulting in a truly natural-looking tan.
