I tend not to reach for serums that are thick or stay sticky for a long time in the morning, but this one absorbed lightly, so it felt less burdensome. After absorption, it left a subtle hydrated glow rather than an oily shine.

For me, since sticky or heavy skincare feels burdensome, the watery application was its biggest advantage. I was also happy with the hydrated glow it left after absorption, so I have been consistently using it in my morning-and-night routine lately.
