I have two 4 GB sticks in my current build , similar to this one , and have never had any issues . Even with two monitors . Why do you say it ' s necessary ? <| sep |> So Aquaphor is an occlusive , which means it helps seal in moisture . I ' m assuming that you ' re probably dealing with some peelingdryness from the treclin , so if I were in your place , my routine would bewash faceapply treclinapply moisturizerapply AquaphorThe healing ointment is the version of Aquaphor that people are so fond of here . FYI it takes very little Aquaphor to cover your face think a dime or nickel sized blob shit I just realized you ' re in the EU around the size of a pound coin or less . Warm it a bit between your fingers for easier spreadability . You ' ll definitely want to give your face at least a water rinse in the AM to get off any residue that remains as well .
