Gently apply the firming Flay Serum in a thin layer after cleansing in the morning and evening. If you only use the serum for the eye and mouth area, then apply the Moisturizing and Toning Gel or the Extra Moisturizing and Toning Gel to your skin. If you use the serum for the whole face, you can do without the gels and apply the day or night care straight away.
