The serum is the first Nourishplus step. It is the lighter layer that goes on clean, dry skin before moisturizer.
Layer it simply
Apply a small amount of serum, let it settle, then use the cream as the second step. In the morning, finish with SPF.
When to choose the set
If you are starting from scratch, the set is usually the cleaner first order because it includes both the serum and the cream in one routine.
