How do I use LT Lipstick?
Open the cap and gently place the LT Tip inside your mouth, just behind the lower lip.
Collect saliva by performing 4 to 5 right-left movements, making sure the foam tip remains in contact with the inner lip.
Next, close the cap halfway to activate the result process — you’ll hear and feel a click.
The process is simple, non-invasive, and takes only 20 seconds.
Finally, push the cap all the way down to clean the sensor and turn off the device.

How do I clean LT Lipstick?
The sensor cleaning process is fully integrated into the usage.
Each time you finish a test and close the cap, integrated UV leds start automatically to sterilize the saliva foams for 30 minutes.
Additionally, we recommend cleaning the foam once a week under regular tap water for a few seconds, and gently drying it by pressing it against a towel for about 10 seconds.

How does diet affect glucose levels?
Poor eating habits lead to harmful glucose spikes and excessive insulin production, which can result in low blood sugar levels and trigger feelings of hunger.
Responding to that hunger often continues the high-low cycle and promotes overeating.
The LT App analyzes your glucose levels and food choices to provide personalized dietary recommendations that help you maintain stable eating habits, reduce glucose peaks, and improve your overall well-being.
We focus on simple, easy-to-implement advice, and help you track gradual improvements in your glucose levels and HbA1c progress — step by step.
