Day Solution Spf

So I have been using the Neutrogena Advanced Solutions Acne Therapy System
with the 3 bottles.
well. im on day 4. i have been seeing changes. which is good.
in the morning i use each bottle as directed.
but at night i only use the cleanser and the acne control lotion as it says. but the acne control lotion leaves my face feeling tight and dry. like i cant even move it.
but this only happens at night cuz i dont apply the other lotion that i use in the morning which has SPF 15 so they were would be no purpose in using that at night.
my question is. if the tightness and dryness will go away after i keep using it. or if i could buy the Oil Free Acne Moisuturizer also from neutrogena bought seperately with this 3 step kit. but i would only use it at night.
if that makes sense. haha
