Dr. Jart Ceramidin Serum

Dr. Jart is always so generous with samples.

If you buy one pack at Olive or buy 10 at a time from 11st, you can get various pouch and tube types

They include a sample, and it makes you want to buy the full-sized product after trying it.

Especially since this serum replenishes moisture deep within, it is so hydrating.

It was good, but... it's been discontinued now.
