These are made from a polished, acrylic material and are the firmest/sturdiest of all. In appearance, they are a little shinier or glossier than the mink or synthetic, and when applied thickly, more dramatic. While they come in a wide variety of thicknesses and curls, and can be applied to look very natural, these are most popular with ladies wanting a more dramatic and made-up look. They hold their curl extremely well due to their firmness. Some people don’t find them as ‘soft’ or ‘natural’ looking than silk or mink eyelash extensions, and while they last a long time, the thickest type don’t have quite as good staying power as the silk and definitely not the mink. They are most suitable for those with healthy, dense lashes of their own, and are generally favoured by younger clients. However because they are heavier in weight than silk or mink eyelash extensions, for many people they are not a great option for long term wear that cause no thinning of natural lashes. On those with very thick natural lashes, they can look simply fantastic!
