"As the Esse Probiotic Serum touches your face, 50 million live probiotics per drop are activated by the moisture on your skin. These living cells complement your natural microbial diversity and help to slow the ageing process.
Directions for use: Use in the evenings for a week or until an improvement is seen. Thereafter, reduce usage to every other day for a week and then even further to 1 or 2 times a week for maintenance only."
