Questions

Common questions

Is the Haruharu Wonder Black Rice Hyaluronic Serum or the The Inkey List Hyaluronic Acid Serum better?

They share 70% active-ingredient overlap based on published INCI lists, so one can stand in for the other on the actives that matter — chiefly Hyaluronic Acid. A dupe matches the hero actives, not the full sensory experience, so expect differences in texture, fragrance and exact concentrations.
Can I use the Haruharu Wonder Black Rice Hyaluronic Serum and The Inkey List Hyaluronic Acid Serum together?
They both fill the serum slot in a routine, so you'd normally pick one rather than layer both. If you want to use both, treat one as your daytime option and the other for evening, and patch-test when introducing anything new.
