If you are not in the constant need to cover and hide your nose ring, you can use this simple trick. All you need to do is take out your nose ring, stud, or any other jewelry and thoroughly clean the piercing spot.
Makeup Hiding
After that, you need to apply a makeup concealer and spread it on and around the spot. Gently smooth and cover the area with face foundation in the suitable color of your skin. Not to look suspicious, I suggest applying the foundation all over your face.
Hide-And-Seek With A Nose Ring
In case you have your septum pierced, and the barbell is your jewelry of choice, the only thing you need to do is turn it upwards. Then, hide it in your nose, and no one can see it except if you are very tall, and people can look up to your nose.
These are the best solution for you if you need to hide your pierced nose for an extended period. If you always take out your nose ring or a nose stud, you will cause the pierced tissue’s healing process.
Plugs are an excellent choice for bigger holes in the nostrils as they will fill it entirely. With a little foundation or face concealer, it will be hard to spot the piercing area. Plugs come in different colors so that you can choose them by your skin tan.
Depending on the nose ring and jewels you wear, you can choose the retainer that exactly fits the hole. They are specially designed to replace the ring or gemstone in your nose whenever necessary.
The retainers’ materials are usually neutral or nude color so they can easily blend in your skin tone. However, they are efficient only when there is a small hole. For larger ones, it is better to use plugs.
These pieces are skin-friendly, and they come in all designs similar to the nose ring you use. Another advantage of retainers is that you will be safe from closing the pierced place. Whether it is a straight barbell or L shape screw, it will fit and camouflage the pierced spot perfectly.

Covering Technic
Taping the piercing is an excellent way to solve the problem, yet it is visible and not exactly hiding. However, tapping piercing with some cover bandages is more than useful and practical when you need just a safety cover and not a hiding trick.
Usually, athletes use taping technic to protect their pierced spots and jewelry while training or playing a match. When the piercing is left exposed, they can quickly rip it off during the game.
On the other hand, taping will allow them to wear their rings without worrying about healing, retainers, and perfect covering.
