I'm not using Sebutape, just eyeballing it based on how much oil appears on the blotting sheets that I use. I know I could be more scientific about it and use Sebutape, but if the improvement from a product is so minor that I can't see a difference on a regular blotting sheet then it's useless as far as I'm concerned.
I'm applying the 5 Alpha Avocuta cream to only the right side of my nose (I always apply these kinds of topicals to just one side). I haven't noticed any changes from that yet. I didn't have much faith in it to begin with, but I'll still keep it up for at least a month.
