I love both brands, but I wanted to know which one actually hydrated my skin more.
I ran a split test for 2 weeks. Left face: Hada Labo Premium. Right face: Cosrx Snail Mucin 96.
I used a skin analysis app (Skintale) to measure the "Hydration/Texture" score of both sides every morning.
Data:
Hada Labo side: Hydration score increased by ~12% on average.
Cosrx side: Hydration score increased by ~8%, but "Redness" decreased more.
It seems Hada Labo wins on pure moisture, but Cosrx is better for calming.
Thought this sub might appreciate the geeky breakdown!
