"Top 7 " Eyelash Enhancer Serums

GrandeLash-MD is an award-winning lash serum that promotes longer and thicker lashes in six weeks, according to the company website. It has many positive reviews online.

 The company is transparent with its ingredients, making them easily accessible on their website. It contains ingredients like hyaluronic acid, which helps to condition lashes, along with amino acids and antioxidant botanicals.

 However, when we looked at the ingredient list for this top eyelash serum, we saw a red flag, a prostaglandin ingredient. Prostaglandins are known to cause eye and skin discoloration and may be dangerous if used when pregnant. With these potential risks, we want a product that’s prostaglandin free.

Rapidlash is another unique lash serum that is formulated with polypeptides, biotin, panthenol, amino acids, soybean oil, and pumpkin seed extracts. Manufacturers claimed that RapidLash Serum moisturizes, strengthens, thickens, and enhances the overall lashes within 4 to 6 weeks.

We appreciate that RapidLash is reasonably priced. It is easy to apply and comes with a 60-day money back guarantee.

However, RapidLash contains chlorphenesin, Alcohol Denat that may cause some side effects. Also, it has a prostaglandin analog, an ingredient used in the treatment of glaucoma, which may cause watery eyes, blurriness, irritation, stinginess, itching eyes, changes in iris color. Some customer reviews we analyzed that results may take up to 12 weeks or more and not 4 to 6 weeks.

 Out of all of the eyelash growth products our testers analyzed, LashFood was the only lash serum to be Ecocert compliant. This certification indicates the company’s commitment to sourcing organic ingredients. Plus, many of this eyelash serum’s total ingredients are from natural origin. This means no prostaglandins, silicones, parabens, petrochemicals, synthetic dyes or mineral oils—a major plus for conscientious consumers.

 LashFood contains a blend of herbal extracts designed to fight the loss of lash hairs, soy protein to help strengthen lashes, and lavender water, which is known to support healthy lash growth.

 Unfortunately, testers didn’t see the results they hoped for when using this eyelash enhancer serum. To grow longer eyelashes, we suggest trying one of the other top eyelash serum products reviewed here.

LiLash claims to nourish the lash follicle to promote the enhanced appearance of length, thickness and curl.

 We like that LiLash offers a 90-day money-back guarantee, and that the company is transparent, including its full ingredient listing on the website. We appreciate when an eyelash serum manufacturer stands behind its product.

 However, testers did not see a significant improvement in lash thickness and curl as promised. Though LiLash eyelash booster does condition and nourish lashes, we had hoped for more dramatic results.

neuLASH is a popular eyelash enhancer serum formulated with polypeptides, hyaluronic acid and conditioning ingredients to fortify lashes. It also contains pumpkin seed extract, which is rich in lash-essential vitamins and minerals.

We had to do some digging since the company does not post its complete list of ingredients online. What we found: Like some of the other top eyelash serum products we tested, its ingredients may cause unwanted side effects. neuLASH contains a prostaglandin analog, which has been shown to cause sensitivity, change in iris color, drooping of the eyelids and even infection. This ingredient, along with other types of prostaglandins, is banned in Canada.

Last on our list is Lancer’s lash conditioner. We noticed instantly that the company website is missing vital information, such as the size of the product (for a pricey $150, we want to know how much serum is contained in one tube).

Lancer eyelash serum does feature peptides in its formula, but it also contains a prostaglandin analog. This ingredient is known to cause severe reactions, including eyelid drooping and infection. With an eyelash growth serum, safety is paramount, and this product does not make the cut.
