Lash lift is popular in Asia A lash lift is a cosmetic treatment that enhances your natural lashes by curling them upward, making them look longer, fuller, and more defined. A perming solution is applied to lift the lashes from the base, and the results last about 6 to 8 weeks, depending on your lash growth cycle. Unlike lash extensions, which add artificial lashes, a lash lift works with your own lashes for a natural look, eliminating the need for daily curling or mascara. It's a great option for those who want low-maintenance lash enhancement.
