Not great for my skin
I tried several serums from the Inkey List and this one did not work great for me. The texture was a bit sticky and did not settle into my skin and caused pilling. The polyglutamic acid serum works much better for my skin.

Strengthen and supports skin barrier
I use this day and night, and it plays perfectly in both routines:
AM: keeps my skin calm, hydrated, and resilient under sunscreen and makeup
PM: seals everything in and helps my skin recover overnight
This is the product I reach for when my skin feels stressed, overworked, or just needs extra love. Consistent use has made my skin feel more stable and less reactive overall.
