The Best Lash Growth Serums to Lengthen and Strengthen Your Lashes

The RevitaLash conditioner is a bit of an investment, but online reviews say it’s worth it. Reports of lashes seeming twice as long immediately are all over Sephora, Ulta, and Bloomingdale’s websites. Many said they saw results in four weeks, which is markedly quicker than others on this list. One online reviewer stated, “This really works. It's pricey but should last a good while since you only need a little bit each night. My lashes are noticeably full and LONG.”

Tried and true in the haircare space, the Olaplex brand has been popular for years. So why wouldn’t they be great at eyelashes, too? Olaplex's new eyelash serum uses bond-enhancing ingredients that help thicken and strengthen lashes. The serum vows to repair and strengthen the lash bond, reducing the risk of hair loss over time and leaving lashes thicker and softer.

Velour Lashes eyelash serum uses a combination of 10 amino acids to stimulate keratin production. This serum promises to keep your lashes strong and prevent breakage and hair loss along the lash line.

This formulation is packed with six amino acids, helping your own production of collagen and elastin. The richness helps strengthen and condition lashes to help them feel longer, fuller, and softer.

Just like how even the best skincare tools can’t quite replicate the full effect of a professional procedure, a prescription treatment is a bit more effective than over the counter lash growth serums. Latisse is the only FDA-approved eyelash serum for eyelash growth as of publication. It contains a prescription-strength prostaglandin analog that supports the development of existing eyelashes and stimulates new hair growth. Because it's so powerful, be sure to talk to your doctor about possible risks such as eye irritation, eye color changes, and eyelids darkening. If you wear contact lenses, you’ll need to remove them before application (and soft lenses may absorb the product). Consider switching to eyeglasses—our list of the best places to buy glasses online is a good starting point.

Looking to try a lash serum, but don’t want to make a huge investment? This Neutrogena product is a great option, can be found at your local drugstore and is 10 times more affordable than others on this list. This hydrating serum is rich in biotin and peptides that form a nice coating to make your lashes feel softer and fuller.

With 4.7 stars on Ulta, this one is a fan favorite. Pacifica’s eyelash serum is vegan, cruelty-free, sustainably-packaged and can lengthen your lashes in just a few weeks. The white formula is easy to apply and contains hydrating collagen and regenerating vitamins B and E.

The hyaluronic acid and aloe inside the Augustinus Bader serum help draw moisture into dry lashes. One online reviewer said, “For the first month or so, I thought this was doing nothing, but I continued to use it since it is so pricey. After about six weeks, my brows started to fill in, even in places that were bare for years. I now have full brows, and I even have to trim them which I haven't had to do since I was a teen.”

Made with a trio of healthy oils, this eyelash and brow growth serum promises to promote the appearance of longer, fuller lashes and brows without harmful ingredients.

GrandeLASH-MD is an award-winning serum that uses a prostaglandin analog to promote the appearance of longer, thicker lashes when applied to the upper lash line.

The HEXATEIN® 1 Complex in this lash serum is specifically designed to condition, hydrate, and strengthen lashes to improve the overall appearance. One reviewer said, "I have been using this for a month now and have seen a tremendous amount of lash growth! I make sure to incorporate this into my a.m. and p.m. routines for best results."

If you have blonde or ginger eyelashes, you can darken them with this growth serum. The double-dose lash serum has eight active ingredients and is 100% cruelty-free. The combination of peptides and natural extracts helps darken and lengthen lashes and brows.

This dual-action eye and lash serum has hyaluronic acid to improve the appearance of crow's feet and undereye wrinkles while thickening lashes. If you want to reduce the appearance of wrinkles and firm the skin around the eyes while visibly strengthening lashes, this one's for you. For even more benefits, consider adding one of the best anti-aging eye creams to your skincare routine.

It doesn't get more natural than this. Sky Organics' eyelash growth serum has exactly one ingredient: cold-pressed castor oil. The USDA-certified, organic, vegan serum supports stronger, fuller lashes by coating them in rich, natural fatty acids.

Reviewers were surprised how much this budget-friendly lash serum defined and fortified their lashes. Maybelline's formulation, with arginine and Provitamin B5, aims to condition your eyelashes, making them softer and more curlable. Apply from root to tip and along the base.
