I love these ampoules. If your skin is looking tired and/or dull, the Energising Oyygen fluids give it a new lease of life. They are simple to use and brighten the skin immediately giving it a freshly revitalised and hydrated finish that lasts throughout the day while feeding the lower layers of your skin for longer term accumulative results. Fantastic during a season change, post illness, during a stressful time or leading up to a special occasion. Use every day in the morning under your moisturiser and use a whole one at a time for optimum results ... enjoy!
