Our strongest formulation, Effiulgere Ultra is used at the direction of your skin care specialist to provide "pulsed stimulation" of the skin. Typically Effulgere Ultra is applied on a daily basis or every other day. Effulgere Ultra is formulated to provide the deepest level of penetration to stimulate dermal tissues. Because of its potency some patients experience some redness and mild irritation after using Effulgere Ultra and should adjust their activities accordingly.
