Longer lashes

This really does make your eyelashes grow!!

Good and reliable quality!

I have been using this eyelash serum for about a month now, and noticed that my eyelashes have got slightly longer. I cannot say they have got thicker, but may see it later on. What I like about this product is no irritation on my eyes at all. The brash is well crafted, and easy to apply on my eyelash roots. I highly recommend it.

I love the super thin brush!

The ACTIIVE Amplify Lash & Brow Serum has a thin brush that makes it really easy to apply right along the lash line. The instructions say to use it on clean, dry skin after washing your face and letting it dry for about 45 seconds. It also works well when applied to brows, which I love for getting more out of one product.After a couple of weeks of consistent use, I noticed my lashes looking a bit thicker and fuller. As someone whose lashes are definitely getting thinner with age, this felt encouraging. I did not experience any redness, stinging, or irritation, which is always my biggest concern with lash serums.It is on the pricier side, but the quality feels comparable to other lash serums that cost even more, so it feels fair for what you are getting. Like any hair growth product, patience is key to seeing changes, but I plan to keep using it to maintain the results. One tube should last a couple of months, which helps justify the price.

Noticeable results

This serum is lightweight, non irritating, and easy to apply, and I’ve already noticed my lashes and brows looking thicker and healthier after a few weeks. The plant-based formula feels gentle yet effective, and a little goes a long way. Vegan, clean, and truly works highly recommend!

Non-irritating and easy to apply

I was not blessed with long lashes and full brows and it has been made even worse by a medical condition. I rely on products like Actiiv Amplify Lash & Brow Serum in addition to supplements to give them a boost. The Amplify serum is so easy to apply with the fine brush applicator. It isn't irritating to my sensitive skin or eyes. The instructions state to use one dip for both eyes. It takes very little product to get results, making the tube last a long time. It contains Norbimatoprost, which may promote lash growth, but is also used in ophthalmology to reduce intraocular pressure. My pressure is on the high end, so this is a benefit for me. Others may not feel the same. I am pleased with the serum so far.
