How long does a 35 ml bottle of OKEY last?
35 ml may look compact, but OKEY is not intended for heavy daily application. A thin layer and an infrequent routine tailored to you make the product economical.

Short answer
When used 1–2 times a week in a thin layer, one bottle may last up to six months. The actual period depends on the area, frequency, and amount of product used.
What determines usage
The most important factors are the size of the area, the number of roller passes, and application frequency. One small area uses less product than several areas.
The statement “up to six months” is a guide for an economical routine, not a guaranteed period for every user.
A thin layer is enough
The formula does not require dense coverage. Move the roller 2–3 times over the area and distribute the product evenly. If the skin remains wet from the product for a long time, too much has probably been applied.
Excess product does not make the action stronger, but it increases usage and may make the skin less comfortable.
Find the minimum effective frequency
Once a stable result has been achieved, some people need only 1–2 applications a week. Do not use the product more often simply because the bottle is small.
Record your application dates during the first month: this helps you see your actual usage and personal interval.
Store the bottle correctly
Close the cap tightly, keep the bottle upright, and follow the storage conditions on the packaging. Do not leave the product in direct sunlight or in a car that becomes very hot.
