WHAT IS THE PURPOSE OF A SERUM AND WHEN SHOULD I USE IT?

Serums are specially formulated to boost skin cell activity. They work in synergy with creams to produce a strong multiplier effect. Match your soothing serum with a hydrating cream. Any combination is possible, depending on your specific skincare needs. Never use a serum on its own. How much should you use? Dab on before apply cream morning and evening.
