Since OUMERE products elicit a true biological response through gentle yet effective methodology, you will not see results overnight. Quick fixes are dangerous and do more harm than good in the long-run. Clients of OUMERE have reported seeing a clearing of years-long acne within one to two months of daily use. For clients with mature skin, or skin that has experienced acne for more than 5 years, improvement of acne may take more than 4 months.
