What is the difference between essence and serum?

What is the difference in practice?

In a ten step Korean routine, essence is its own step after toner, followed by a face oil, serum or ampoule aimed at a main skin concern. A simpler routine treats serum, essence or ampoule as one optional choice. The names do not define a reliable strength ranking, so check what the product is for and how its label says to use it. Ten steps take time and money, and no routine awards a certificate for completing them.13

Should you use essence or serum first?

If you use both, put essence before serum: the Korean routine example places essence after toner and serum after essence. In general, layer products from thinnest to thickest. If you use a medication or other skin treatment, apply it right after cleansing, before optional products. In the morning, finish with moisturizer and sunscreen; sunscreen is the final step.145

Can you use essence and serum together?

Yes. A ten step routine includes both, while a shorter routine uses one or the other. Cleveland Clinic advises using only one serum at a time, because using more products raises the chance of side effects. Both can fit, but the product aisle does not get to cast every bottle in a starring role.14

Introduce new products slowly, especially if your skin is sensitive. For anti aging products, the American Academy of Dermatology advises testing a small amount on the inner forearm twice a day for four to five days before applying it to your face. Stop using a product that stings, burns or tingles. If a dermatologist prescribed it, ask whether that reaction is expected.13

Is essence necessary for skin?

No. A basic morning routine can be cleanser, moisturizer and sunscreen, and the shorter Korean routine lists serum, essence or ampoule as a choice rather than a required step. If you want one product for a particular concern, choose according to its ingredients and directions; skip essence if it would only add another step.14
