The 7 skin method

I’ve tried the 7 skin method for two days now and my skin feels so good and hydrated! The deal is that you put seven layers of hydrating toner (without alcohol or any acids) on top of each other and let them absorb in between layers. I think this has helped with my pores as well which makes me to think, that my skin maybe have been really dehydrated and just in need for more moisture instead of BHA and daily exfoliation. Why do you think this works?

I use the Pyunkang Yul Essence Toner, with this very short ingredients list: Astragalus Membranaceus Root Extract, 1,2-Hexanediol, Butylene Glycol, Bis-PEG-18 Methyl Ether Dimethyl Silane, Hydroxyethylcellulose, Carbomer, Arginine.
