Secrets to Properly Exposing the Nail Sinus Before Applying Color
In professional manicure, it’s often the smallest details that determine the overall outcome. One such detail is the correct exposure of the nail sinus before applying color or gel. The sinus areas — the side skin folds along the nail plate — play a crucial role in how clean the application looks and how long it lasts. At MONLIS School in Munich, one of Germany’s leading manicure and pedicure schools, this step is taught thoroughly and with practical focus.
What Is the Nail Sinus and Why Is It So Important?
The sinuses are located on either side of the nail base, where the nail plate gently transitions into the surrounding skin. If these sidewalls aren’t properly prepared, polish may:
Be applied unevenly
Lift or chip prematurely
Appear messy or streaked
Visually distort the nail shape
A flawless look with clean color lines right up to the edges is only possible when the sinus areas are properly prepped before color application.
Step-by-Step: How to Prepare the Sinus Cleanly and Safely
At MONLIS School, students are trained to expose the sinuses gently but effectively, without damaging the delicate skin.
Key steps include:
Gentle cuticle treatment:
Remove dead skin with a remover, pusher, or fine drill bit.Lifting the sidewalls carefully:
Use tools like silicone sticks or orangewood to slightly lift the skin at the edges, allowing the brush to glide in.Good lighting and hand control:
Proper visibility and hand positioning are essential for millimeter-perfect precision.Using a detail brush for color near the sinus:
Students learn to use micro brushes for precise application — getting close without touching the skin.
Common Mistakes When Working in the Sinus Area
Even small missteps when working around the sinuses can significantly affect the results:
Tools that are too rough can injure the skin
Poor prep can cause bubbles or peeling
Color on the skin leads to lifting and uneven edges
Lack of product control causes polish to run into the sidewalls
That’s why MONLIS School teaches not only techniques, but also the “why” behind each step — building a foundation of skill and responsibility.
Why This Technique Sets Professionals Apart
A cleanly executed sinus edge gives the whole manicure a luxurious and polished look. It shows that the nail technician:
Understands nail anatomy
Works with skill and precision
Combines hygiene with aesthetics
Delivers results that clearly exceed standard service
This attention to detail is especially valuable in nude styles, French designs, or minimalist looks.
