Can Timoptic (Timolol) Be Used Instead of Latiisse and Would the Same Effect on Lash Grow

In order to get FDA clearance, a product has to prove to be effective and safe, and for stimulating eyelashes to grow fuller longer and darker, Latisse is the only one. Glaucoma drugs of any type - even Lumigan, which contains the same drug as Latisse - should not be used for eyelashes.

Timolol is an entirely different class of medications with a different mechanism.  Thus it will not provide the expected aesthetic benefit that Latisse provides.

Latisse is FDA approved for eyelash growth, not Timoptic. My recommendation is to stay safe and use the effective dose and formulation! for eyelash growth that is in Latisse.
