Botox can be kept in a medical fridge for up to four weeks, but it must be stored correctly with daily temperature monitoring to ensure it remains safe for use


How long can you keep Botox in a fridge is one of the most common questions asked by cosmetic surgery practitioners administering injections to patients in the UK.

So long as Botox is stored correctly in a medical grade refrigerator, it can be stored for up to four weeks in a fridge while still retaining its potency. 

In order for Botox to be safe to administer, it must be stored between a specific temperature range and that is why a dedicated medical fridge must be used.

Below, we take a closer look at the temperature range Botox must be stored between and how you, as a cosmetic health practitioner, can ensure that temperature is maintained.


Botox should be stored between a set temperature range:

The standard temperature range for storing products used for non-invasive cosmetic procedures, such as administering Botox, is between +2°C to +8°C.

The only way to be certain this temperature range can be maintained is to use a dedicated medical fridge – standard household fridges are simply not up to the task.

Medical fridges come fitted with state-of-the-art thermometers that measure the temperature inside the fridge as well as the temperature of the products being stored inside.

If the temperature they record falls below or rises above the required range at any time, an alarm will sound to alert cosmetic surgery practitioners.

This allows them to intervene and take action to ensure the products being stored inside – in this case, Botox – are not damaged beyond the point of use.


Botox must be stored correctly:

While medical fridges are capable of maintaining a very specific temperature range, it is important to store Botox products correctly if they are to be kept in a usable condition for up to four weeks.

To do this, you should leave 1cm of space between products and ensure that products do not touch the back or side of the fridge as this can lead to freezing. 

The medical fridge should never be more than 75% full and Botox should be kept in its packaging to prevent light damage from occurring, especially if the fridge has a glass door.

Fridge cleanliness is also important – external surfaces such as handles should be wiped down daily while the inside of the fridge should be fully cleaned twice a month.


Temperature monitoring is key to safe Botox storage:

The final factor required for the safe storage of Botox products for up to four weeks is daily temperature monitoring and logging.

Cosmetic surgery practitioners must log the temperature of the fridge used to store Botox at least twice per day – first thing in the morning and at the end of the day.

This is to ensure the temperature has not fallen outside of the required range. When temperature monitoring and logging, remember the four “Rs”…

  • Read
  • Record
  • Reset
  • React

This means reading the temperature and accurately recording it in a dedicated temperature log. The person logging the data must also sign their name against the entry.

Recordings should be taken for current, min and max temperatures. Once the recording has been logged and signed against, the thermometer must be reset.

If the recording shows that the temperature has fallen below or risen above the required range during the night or the day then they must react.

By using a dedicated medical fridge and following the steps outlined above, Botox can be safely stored in a fridge for up to four weeks and still be safe to administer to patients.

Of course, it is always best to check storage times with the product manufacturer.
