How to use Latisse after 4 months?

Thank you for your question.It is possibly that by 16 weeks you have reached your maximum result. Your lashes will continue there normal shedding cycle, so continuing the use of Latisse is required to keep lashes at your desired goal. Once you have achieved the length of lashes desired, you can use latisse every other or every third night for maintenance. To be sure, see two or more board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment.I hope this helps.

You could try using as directed for an additional 1-2 months, if you see no further improvement you could go down to using it every other night as up keep. 

Thank you for your question. Some patients continue to see results after 4 months of continuous use. Consistent use of Latisse may provide thicker fuller lashes, once you have reached the desired length use Latisse every other night.
