This is, by far, my personal favorite Essence. It feels so rich without the annoying stickiness. My skin type is a bit sensitive + dry.
I would just replace moisturizer with this essence in a hot day. My skin does feel cleaner and healthy after 1 bottle usage. This will definitely be the only one for me when it is available!
People are saying that Tony Moly's first essence is as good as a SK II 's treatment essence, which cost around 150 USD. If you read through their ingredients, you will find they actually have certain similarities. So... I guess $38 Essence is definitely a steal for skincare lovers!
Her skin type is more towards Oliy type I believe. I agree with her that Tony Moly might works better with Dry Skin and it is the most close one to SK II. Tony Moly part starts at 5:10 in below video
