Frequently asked questions
Can I use Biodots more than once?
Yes, however, the adhesive will not be as effective each time the dot is removed and replaced.
How long do Biodots last?
Biodots will remain active for years however, we advise you to purchase only the quantity you will use within a year. The dots should be kept in dry conditions at room temperature.
Do Biodots only change colour once?
No; Biodots keep changing colour as your skin temperature changes.
How long will the Biodot stay on my hand?
Biodots can stay attached for days, however, the length of time your dot will stay depends on the surface properties of your skin. Moist and oily skin is not good for adhesion. Cleaning and drying the skin will help improve the adhesion. Check also that your dot is not being dislodged by cuffs and sleeves.
Why doesn’t my Biodot change colour very much?
If you have peripheral circulatory problems in your hands you may need to use Low Temperature Biodots. These dots change colour at a lower temperature range. In cold conditions Low Temperature Biodots should be used since blood flow will be reduced to conserve body heat.
Are Biodots safe to use?
Yes, however, users with allergies to adhesives are advised, as a precaution, not to apply Biodots directly to their skin. Instead apply a suitable thin layer of non-allergic barrier material to the skin and place the Biodot on this material.
Biodots should only be used on the skin; external use only. Biodots are not suitable for use on young children unless they are supervised by an adult.
Does anything else, apart from stress, change the colour of the Biodot?
Yes; anything that changes the skin blood flow will lead to a change in skin temperature and hence the colour of the Biodot.
