lovely first essence [SEP] this is kind of like a cross between a toner and a serum i have been using it kind of like klairs moisturizing toner even though it is a little thinner than that it slaps on and seems to spread over my face nicely sinks in very quickly and provides a nice boost of moisture prior to putting on a thicker serum and then moisturizeri had been reading about this product for really long time before trying it and it is kind of a cult favorite in the k beauty world i can see why it is not flashy but as a first thing to splash on your face and hold in some of that moisture it works well and does not clash with other products
