LATISSE® eyelash enhancer is the first and only U.S. Food and Drug Administration approved cosmetic treatment for increasing the length, thickness and darkness of eyelashes. Available only through prescription, it is applied once a day to the base of the upper eyelashes. Results may be apparent within four weeks; full results can take up to sixteen weeks.
Exactly why LATISSE liquid solution causes eyelashes to grow is unknown. However, its active ingredient, bimatoprost, seems to increase the number of hairs in, and the duration of, a hair follicle's growth period. The result is longer and fuller lashes.
Once LATISSE treatment is discontinued, its benefits gradually end.
Application of LATISSE Solution
LATISSE solution is applied at night, every night. Contact lenses and makeup should be removed and skincare products applied, before using the LATISSE solution.
To prevent contamination, the LATISSE solution is applied with a single-use disposable applicator. The applicator, which is coated with one drop of solution, is applied to the base of the upper eyelid, at the lash line. The applicator is moved from the inside of the lash line to the outside. Excess solution is blotted to prevent its spreading to other areas.
Contact lenses can be put back in 15 minutes after LATISSE treatment.
Risks of LATISSE Treatment
Side effects are thankfully exceedingly rare. If the liquid is applied too generously or on areas other than the upper eyelid lash line, it is possible to get unwanted hair growth in those locations. A rare, but permanent side effect of treatment is a possible increased brown pigmentation of the iris (ie. coloured part of the eye).
