Always use it over a face oil or serum. The tool should glide, never drag. If it catches, add another drop. Hold it almost flat against your skin, at about 15 degrees, and use light pressure. Firmer is not better on the face. Always stroke outwards and upwards, from the centre of the face towards the ears, then down the sides of the neck. Three to five strokes per area is enough. It is stainless steel, so it stays cool. Pop it in the fridge for a few minutes first for an extra de-puffing effect in the morning. Five minutes, three or four times a week, is a good routine. It is a relaxing ritual as much as a skincare step. Wash it with warm, soapy water after each use.
