LED lashes look and feel pretty much the same as regular eyelash extensions, and are brilliant for people who have sensitive eyes that are prone to redness or sensitivity during the eyelash extension procedure. Whilst most find regular eyelash extension application comfortable, certain individuals with very dry eyes can find it causes their eyes to water. The LED application method eliminates this in most cases, due to the curing mechanism. The adhesive cures instantly by LED light – there are zero residual fumes, and the lashes can be exposed to water or even oil immediately after the treatment without any problems. So for swimmers or those with very oily skin, it can be a real benefit. They are best for those who want to get as long as possible between infills – retention is usually improved with this oil-resistant glue, and you may be able to get an additional week between infills.
