What SPF can I use if my ARTISTRY® moisturiser has no SPF?

An application of ARTISTRY Exact Fit® Beauty Balm Perfecting Primer will give you SPF 25.  Apply after your ARTISTRY moisturiser.  Alternately, Illuminating CC Cream provides SPF 25, Exact Fit Longwearing foundation provides SPF 15 and Youth Xtend Lifting Smoothing Foundation & Exact Fit Powder Foundation provide SPF20.  For high sun protection we suggest Suntime SPF50.
