Silicone earskins and eyelets are a popular choice due to their light weight, comfort and versatility. Their soft, flexible material makes them great for exercise, sleeping, and participating in sports, and silicone is also great for cold weather or water-based activities. They're mostly worn in lobes, but the smaller sizes are also useful for things like stretched septums.
Please note that while silicone is a great material, it is for fully healed piercings, and not recommended for stretching or freshly stretched lobes.
You can also wear multiple earskins at once to get a stacked effect! You just need to go down one size for each additional earskin.
Smaller earskins can be a bit tricky, and might require a slightly different technique.
Because silicone is soft and flexible, this should not be painful, however as always, if anything ever hurts, stop and let your ears rest. For very small eyelets, tweezers can be used to help grab the jewelry and ease it through your piercing, however please exercise caution when doing so, so as not to hurt yourself or tear the silicone.
Silicone eyelets are very similar to earskins. The main difference is their flat flare, and slightly thicker design. They have a little less give than earskins, but are still perfectly flexible.
