Eyelash extensions can definitely boost confidence and reduce the need for daily makeup, but if you have sensitive eyes it's important to be cautious. The fibers themselves are usually lightweight, but the type of glue used makes the biggest difference — low-fume, hypoallergenic Adhesives are best to minimize irritation. With the right products and proper care, many people with sensitive eyes can wear extensions daily, although doing a patch test first is always a smart idea.
