After cleansing, prepare the skin with toner. Remove the sheet mask from the pouch and apply evenly over the face, adjusting around the eyes and mouth.

Leave on for 10–20 minutes, then remove the mask and gently pat or massage the remaining essence into the skin until fully absorbed. Do not rinse.

Use whenever the skin looks dull, tired or uneven, or before an event when you want an extra bright and hydrated-looking finish. Because the formula contains Vitamin C and Retinol among its ingredients, customers with sensitive skin should patch test first and avoid combining it in the same routine with strong exfoliating acids or other intensive retinoid treatments if irritation occurs. Apply sunscreen during the daytime.
