Review: Helped my fading eyelashes - I recently started using a lash growth serum, and I'm absolutely amazed by the results! This serum has completely transformed my lashes, making them longer, thicker, and more voluminous than ever before. I love how easy it is to incorporate into my daily beauty routine – just a quick swipe along the lash line before bed, and I'm done! The formula is gentle and non-irritating, so I can use it with confidence, knowing that it won't cause any adverse reactions. Plus, the results are truly incredible – within just a few weeks of consistent use, I noticed a significant improvement in the length and density of my lashes. Since incorporating this lash growth serum into my routine, I've received countless compliments on my lashes, and I feel more confident than ever batting my eyes. Whether you're looking to enhance your natural lashes or recover from damage caused by extensions or harsh mascaras, I highly recommend giving this lash growth serum a try – it's a game-changer for anyone looking to achieve longer, fuller lashes!
Review: WORKS GREAT. MORE PRODUCT, NO PAIN - I Love this. I just ordered the brow formula. I find the application process so easy. I love that you get so much product. My eyelashes are coarse. I like when the formula gets on the lashes. It seems to thicken them. I have used Revitalash, which works well, but is $110 and the tube dries out quickly. Same with the brow formula. I saw this and thought if it works, it would be so cost effective. I switched every other day until the revitalash ran out. Well the NYK1 works as well. I’ll write a review on the brow serum after giving it a chance. Ps. I also tint my own lashes black which makes them look crazy noticeable and long. I recommended Aryana lash tint. (Also can be bought at desertcart) It is vegan, but I have accidentally got some in my eye and it hurts. Rinses out easily, but does sting. The best part, after you get used to it, you can tint them beautifully yourself. I had this done professionally and this product looks better and lasts longer. (sometimes 2 months) I recommend the 2 together….. serum and tint. What a difference! And no mascara necessary. EVER

## Features

- LONGER, FULLER LASHES WITHOUT EXTENSIONS OR FALSE EYELASHES - Achieve naturally longer, fuller, thicker lashes that enhance the appearance of your eyes without false eyelashes or extensions. NYK1 LashForce transforms short, sparse lashes into a visibly fuller lash line in as little as 6-8 weeks. With consistent use, lashes appear fuller and more defined, so you can rely less on mascara and enjoy naturally enhanced lashes every day.
- SUPPORTS NATURAL LASH GROWTH FOR LASTING RESULTS - NYK1 LashForce eyelash growth serum helps lashes appear longer, fuller, and thicker over time, with visible improvement that builds week after week. It works at the lash line to support healthier-looking lash growth from the root, so your lashes progressively look stronger and more complete with consistent use.
- IDEAL FOR SPARSE, THIN OR WEAK LASHES - Transform the look of short, sparse or thinning lashes into a fuller, more defined lash line. NYK1 LashForce eye lash serum growth helps lashes appear thicker and more complete over time, restoring a naturally fuller-looking lash appearance whether lashes have been weakened by extensions, frequent mascara use or are naturally sparse.
- CONCENTRATED LASH SERUM WITH LIGHTWEIGHT, INVISIBLE FORMULA - One 3ml bottle is designed to support consistent daily application as part of your lash care routine. The clear, fast-absorbing formula dries quickly and sits invisibly on the lash line with no greasiness or residue, making it ideal for use under makeup or as part of your morning or evening routine.
- GENTLE, EASY-TO-USE LASH SERUM FOR DAILY APPLICATION - Apply this lash serum like liquid eyeliner in just seconds, morning and night. Developed as a prostaglandin-free lash serum, it’s suitable for sensitive eyes and contact lens wearers. If you’re looking for a gentle eyelash serum that’s easy to use daily, LashForce offers a simple, low-effort way to support longer, fuller-looking lashes with confidence.

### ⭐⭐⭐⭐ Seems to be working….
*by D***G on February 27, 2023*

I have Hashimotos Thyroid and have battled hair & lash fallout for 3 decades. That’s right, 30 years. At first the Dr prescribed Lattese which made my eyes constantly red, but grew lashes so long that they banged uncomfortably into my sunglasses. Since I didn’t like the idea (or cost) of using a chemical on my eyes, I switched to Grande Lash MD. It was less $$ than lattese and worked pretty well, at least for the first 6 months. It seemed to be working less well as the months went by so I began trying other brands of herbal type lash serums but none worked hardly at all. I almost didn’t order this one - it just seemed too inexpensive - but I was more than tired of shelling out buckets of $$ for lash serums. So I gave it a go. Here’s what’s different from other brands: Big tube with plenty of product They instruct you to use twice daily: am & pm. They tell you to massage it into the base of your lashes. While I’d rather it wasn’t made in China, it seems to be a safe product. I’ve had zero irritation or stinging - even when accidentally getting it into my eye. I stopped using my Grande Lash & started using this. Within a week I began seeing extra length on my lashes. By the second week my lashes were noticeably thicker - meaning there were more lashes growing - not that they were becoming more coarse. And last night (about a month of use) 2 friends both commented on how long & lush my eyelashes looked. So I will definitely be ordering again.
