Step 1: Clean the face thoroughly with water to ensure that the skin does not have any cosmetics or other skin care.

Step 2: Wet the nose area thoroughly with clean, warm water. Please note that if the skin is dry, the adhesive strip will not stick.

Step 3: Open the sachet sachet with dry hands, and then peel it off the liner.

Step 4: Place the test strip on the nose with the light side down, taking care to smooth out bubbles or creases.

Step 5: Let the strips dry naturally for about 10 to 15 minutes, and then carefully start peeling the strips from the ends to the middle. If the strap is secured too tightly or is difficult to remove, thoroughly wet the area until the strap is easy to remove.

Step 6: When the outer strip is completely dry, you can peel it off. Precautions: For nose only. Not suitable for use around the eyes. If the test strips do come into contact with eyes, rinse immediately with clean, warm water.
