## Description

Boost lash growth and thickness with this concentrated serum, formulated to stimulate blood flow and clear follicle blockages for amazing results in 6-8 weeks.

Review: Great product - Second time ordering this product. It works really well and was recommended by a friend definitely worth the money and last ages
Review: Very noticeable improvement! - Genuinely didn’t expect much out of this stuff, but I’m happy to be proved wrong! It’s very thin almost like water. Read the instructions and have been applying religiously morning and night for a month ‘drenched not dripping’ to quote the directions. My short stubby eyelashes are noticeably longer, and seem to have thickened up. Will definitely continue with it I’m impressed so far.

## Features

- YES IT'S TRUE, EYELASH SERUM REALLY WORKS - but not all of them, so don't be fooled. This eyelash growth formula is #1 eyelash serum for growth, but please be patient; lashes and eyebrows will see amazing results in 6-8 weeks. Experience amazing rapid lash growth with NYK1 Lash Serum and Brow Growth Serum. Our Eyelash Enhancing Serum has been tested and perfected. You must try Lash Force to believe it.
- EXPERIENCE 3x LASH GROWTH WITH THE BEST EYELASH GROWTH SERUM - It works differently to other Serums out there. Rather than conditioning the Eye Lashes and Brows, it stimulates blood flow whilst cleaning and clearing the follicles of blockages. More nutrients means amazing results. Consistent morning and night application is the key, otherwise you will limit nutrient flow and break the growth cycle resulting in poor results. Used correctly this Eye Serum Growth will not fail.
- APPLY TWICE PER DAY LIKE LIQUID EYELINER - Roots must be drenched, but not dripping, in NYK1 Eyelash Serum LashForce twice a day. Missing one application will hold up the process. Continual cleansing and stimulation is vital to achieving maximum results. Get dramatic natural eyelashes, lashes and brows. The results really are that good! In 4 weeks your Lashes will be thicker, darker, fuller and up to 2x longer by weeks 6-8. Lasts more than 3 months using twice per day.
- APPLY IN 10 SECONDS - Just twice per day on clean skin just like liquid eyeliner to the base of the eyelashes and/or into the eyebrows. The eye lash serum has a clear, thin consistency that is totally unnoticeable. Perfectly safe for contact lens users and will not alter eye colour like some other brands. Dermatologically and Ophthalmologist tested. NYK1 Lash Force is safe to use. No need for magnetic eyelashes, eyelash extension kit or a lash lift and tint kit.
- UNBELIEVABLY LONGER NATURAL LASHES AND EYEBROWS - Remember LashForce is also an eyebrow growth / eyebrow serum. If you want thicker, darker rapid brow growth, especially if you have a bald spot and want to fill it back in with your own Natural Hair, instead of having to pencil in specific gaps. Amazing at natural eye lash growing instead of using a Lash Extension Kit. Advanced Eye lash hair growth serum results amplified by mascara and eyelash tint.
