In my opinion, Latisse is a better option because it's not damaging and it's not "fake" looking. I see many, many people over time who damage their lids, follicles, and lashes from extensions. Remember that Latisse is your own lashes. There is no glue or anything applied and you won't have any damage should you stop using it. Lash extensions have to be maintained and reapplied, and there can be severe damage to the lashes if you stop doing it, namely it pulls out your lashes and they may not regrow. The normal price for a 3ml bottle of Latisse is $120, and a 5ml bottle is $179. Also there is a program called Brilliant Distinctions (from Allergan, the manufacturers of Latisse) that is a "frequent-buyer program" of sorts so that you can get discounts from repeat purchases of Latisse. In my office, the cost is just the cost of the prescription, but other offices will vary on that part. Also, as far as prescribing, some derms, plastic surgeons, and ocular surgeons will carry and sell Latisse directly from their office. Otherwise, any doctor can give you a prescription to fill at a pharmacy for it, but you won't be able to participate in the BD program through a traditional pharmacy. Best best, check the Latisse website - there's a find a doctor section on it where you call offices close to you who prescribe it.
