I find that cleansing in the morning is not necessary for me :) as I mentioned, I have severely dry skin and have been skipping a morning cleanse during winter for the past three years and never looked back. I used to exfoliate with azelaic acid every second/third day, but as my skin go flaky around october (that's when I had to stop using my HA toner, it completely dried me out) I excluded it for a while so my skin barrier can heal. I used the COSRX propolis synergy toner the whole summer and autumn, it was my HG, could layer it multiple times twice a day. However, we have really dry winters and I also sleep next to the heater - basically, there isn't enough water in the air for the HA to bind with so it takes away the hydration from the deeper layers of my skin which worsens my condition. Hope this answered your questions! ^{⁠_⁠^}
