Is titanium good for a new nostril piercing?

Yes. Titanium is lightweight and rarely causes reactions, which is why piercers favor it for healing piercings. Have a professional fit it and keep the area clean.

How does a screw stud stay in?

The post bends into a screw shape that follows the inside of the nostril, so it holds without a backing. It can work loose over time, so check it now and then.

Is this safe for sensitive skin?

Titanium is one of the least reactive piercing metals, so it suits most people who react to steel or plated jewelry. Anyone with a known metal allergy should still confirm the grade with the seller.

Can I wear it in a healed piercing every day?

Yes. The plain crystal design is understated enough for daily wear, and titanium resists tarnish and corrosion from soap and water.

Use a saline soak or mild soap and warm water, rinse well and dry it. Avoid harsh cleaners and remove it before swimming in chlorinated or open water.
