I Love it!! It stays on for the whole day and it's easy to apply.
I've been using this eyeliner for about a year, and not only love how easy it is to use, but I've noticed that my lashes are thicker and longer! I use the liner on my top eyelid, always goes on flawlessly, and stays put all day. I always recommend this product to my friends.
As a 56 year old Asian I have very thin and sparse eyelashes. Other mascaras including those with fibers don't work for me, and I can't afford and am a bit scared to try products where there can be irritation. No time and too inept for false lashes. I do like the marker and didn't experience irritation and it's easy to use. Problem is it stays well on my upper lids but smudges fast and fades away when underlining even when going over several times. And it is almost dried out so I don't know if I bought an old one. After several weeks use I don't see any visible difference in length; disappointing based on the positive reviews. Will try the other lash lengthening liner if I can find it.
I've stuck with 3 staple Physician Formula products for many many years and try new ones every now and then. This eyeliner is absolutely one of my staples and has been for about 3 1/2 years. I wear falsies quite frequently and it puts a lot of stress on my lashes. I, personally, don't see any growth in my lashes from the serum but have been complimented on my natural lashes when I'm not wearing falsies and that was never the case prior to using this product. I however don't see my lashes constantly throughout the day, every day as my coworkers, family and friends do. Serum aside, the liner itself is incredible. I find it releases the perfect amount of pigment and the control is incredible. It's perfect for a catwing, simple line or even just basic tightlining. I'm always afraid it's been discontinued because some stores don't carry it all of the time. I might just stock up!
This product is excellent i was able t see results after a couple days. My lashes grow noticeably every day. This is a great buy, and worth the money at twice the price.
