For your skin
Liquid microneedling in a bottle. It causes a temporary prickly sensation but creates tiny pathways in your skin so all your other expensive serums can actually penetrate deeper.

Microscopic needle-like structures harvested from marine sponges that embed in the stratum corneum for up to 72 hours, creating microchannels that dramatically boost the absorption of subsequent actives while stimulating microcirculation.
