Your first night
The first night is about setup, not miracles. Get the application right and give your nose a few nights to tell you what it thinks.
About 10 minutes before bed, wash and fully dry the bridge of your nose, no moisturiser, sunscreen, oil or sweat.
Centre the strip across the widest part of the bridge so both ends sit flat on the sidewalls.
Press firmly for 10 seconds, both ends, not just the middle.
If your mouth tends to fall open, add a small piece of tape across the centre of your lips, but only if your nose already feels clear.
In the morning, remove slowly from one end. A faint line or quick redness is normal and settles fast.
Judge it over 3–4 nights, not one. If the strip lifts early, it's usually skin prep or the wrong lane (XGrip for oily/warm/restless).
