Apply to the base of the upper eyelashes using the applicator brush. The eye should be completely clean of any make-up or eye creams. Start from the inner corner of the eye outwards, directly on the base of your eyelashes. Use once daily in the evening before bedtime.
Can you use neuLASH during the day?
Efficacy tests indicate that it takes approximately 30 days to achieve the appearance of more luxurious, longer-looking lashes. Will I get better results using neuLASH® twice a day? No. A daily application is all that is needed.
Does neuLASH stop working?
The results are not permanent, so once you achieve the results you’re looking for, you must continue using the product to maintain your newly long + thick lashes.
What are the side effects of neuLASH?
There are no reported side effects to neuLASH except for a paper in the scientific literature about the ingredient Isopropyl Cloprostenate causing eye discoloration (1). This has been found to occur with other prostaglandin analogs.
How often should you apply lash serum?
More often than not, lash serums require daily application: in the morning or at night — or twice daily, in the morning and at night. Before applying your lash serum, your face should be completely cleansed of all makeup so that the formula can actually penetrate and strengthen your eyelashes.
Can you use neuLash on bottom lashes?
neuLash can also be applied to the lower lash line. However, use greater care when applying to avoid direct contact with the eye.

Is Neulash FDA approved?
It seems that several products, including Rapidlash, Neulash and NeuveauBrow were using this ingredient, which is very similar to the active ingredient in Latisse (bimatoprost). They did not have FDA approval and were selling it as a cosmetic additive, not a drug.
Does Neulash work on eyebrows?
neuLash can also be used to improve the appearance of sparse, thin eyebrows. Once desired results are achieved, it is recommended to continue using neuLash to maintain the appearance and condition of your lashes and brows.
