Sun protection is the final step of a daytime routine, and many people place an antioxidant such as vitamin C before it.
A typical order is: hydrating step, vitamin C, moisturiser, then sunscreen. Apply sunscreen generously, and reapply when you are outdoors for long periods.
d.nuvo's Aqua C Dual Sun Serum (50 ml) is designed as the last daytime step. Always follow the directions on the pack.
