Use Summer Tan Hydrating Tan Extender with any of Summer Tan's tanning products to intensify or extend the life of your tan whilst nourishing and toning your skin. If used alone it can build a tan gradually over several days or will replenish an existing tan. Added bronzers along with Aloe Vera, Vitamin E and Jojoba provide an all-day skin hydration treatment, and keep your tan for longer.
