Use the amount stated for the specific product. More product is not a reliable route to a better result.
For the Ozera formulas
Our directions call for three to four drops of either serum, a small amount of eye gel — about a grain of rice per eye — and a dime-sized amount of cream. Check the current product page and label before use.
The serums have different timing: 004 in the morning, 003 at night on the evenings you use retinol. Avoid the eye area with the serums and keep eye gel away from the lash line.
Do not make every bottle a daily step
An optional step can stay optional. Using the retinol more often than directed to finish it sooner is not a useful goal. Introduce new products individually and stop if irritation occurs.
Keep sunscreen separate
The amounts above apply to our cosmetics. They are not sunscreen measurements. Follow your sunscreen's own application directions.
How long a bottle lasts depends on the amount used, frequency and area of application. We do not promise a fixed number of months from each container.
