Created by the Rocasuca company, RapidLash launched in 2008. In fact, it was the first brand to make an eyelash growth serum available to everyone, and the company has continued to have success due to the popularity of its products. Their RapidLash eyelash enhancing serum is said to not only work on lashes but brows as well, and creates strong, healthy, unbreakable hairs, according to the company. RapidLash also creates other types of award-winning products that include hair care and feature their own formula of ingredients to bolster and thicken hair.

RapidLash Products

The star of the RapidLash line is the brand’s eyelash growth serum. The serum has been clinically tested, and promises longer, thicker lashes in just four weeks. Easy to apply with a slim, compact applicator, you use RapidLash once every day before bed. According to the company, you should see long lashes in just a few weeks. Use RapidLash in conjunction with RapidBrow to make a difference in the overall look of the eye area. RapidBrow shows results in 60 days, and promises natural-looking brows that are voluminous and dramatic. The brand also states that RapidBrow has anti-aging properties to create a more youthful look around the brow and eye area. Use RapidBrow twice a day for maximum results.

If your concern isn’t just how to grow lashes, RapidHair helps reduce hair breakage and loss as well as improving thinning hair. This hair care product is said to add fullness to lifeless hair and eliminate weak hair by promoting strong, healthy, and shiny locks. It’s a cream you apply from a pump once every day after you wash your hair. RapidLash claims results in 60 days or less. The rest of the RapidLash product line includes RapidRenew, which is an exfoliator for skin, and RapidEye, which uses anti-aging ingredients to smooth and reduce the appearance of wrinkles around the eye area.

Most consumers will see results in four to eight weeks after using RapidLash regularly. This eyelash growth serum must be applied to clean skin using the accompanying brush, and you should use the product once in the evening before you go to bed. Avoid getting RapidLash into your eyes as this could cause irritation.

RapidLash Growth Serum Ingredients

RapidLash’s patented unique formula is called HEXATEIN 1 COMPLEX, and this formula consists of six key ingredients. These include: amino acids, which use proteins to create healthy eyelashes and eyebrows; biotin, which promotes lash growth and hydrates lashes and brows for strength; polypeptides, which help reduce eyelash breakage; soybean oil, which creates the appearance of dramatic, voluminous, and shiny lashes; and pumpkin seed extract, which is packed with healthy vitamins to enhance the overall appearance of eyelashes and eyebrows.

These ingredients, when combined, are said to create a powerful serum that enhances and improves eyelashes while reducing breakage and adding shine and moisture. RapidLash doesn’t contain harmful parabens, and it’s been tested by an ophthalmologist. It’s safe to use if you have sensitive eyes or wear contact lenses, and the company doesn’t test on animals.

Reported RapidLash Side Effects

Though there haven’t been many reports of severe side effects associated with RapidLash, as with any eyelash growth serum, there are a few. Some consumers have reported red and irritated eyes as well as headaches. Other reported side effects include eye twitches and dry eyelashes, and eyelash breakage.

Though RapidLash is safe to use if you have eyelash extensions or wear contacts, be aware that it can irritate the area surrounding the eyes and cause redness. Some severe if though rare side effects from this product may include darkening of the skin around the eye as well as eye iris discoloration, or change of eye color. Avoid getting RapidLash in your eyes when you use it, and though minor side effects may go away after continued use, it’s best to stop the product if continued irritation occurs and see a doctor. Check the directions to ensure you’re applying the product properly.

RapidLash Consumer Reviews

Some users of RapidLash have experienced a doubling of lash length and volume in two months’ time. Some users say since RapidLash removed prostaglandin from their formula, the serum doesn’t work as well as its previous incarnation. However, many women report results in as little as three weeks, with darker, thicker, visibly fuller eyelashes. Some consumers are disappointed in the high price of the product, but do maintain that it’s worth the cost since it actually works.

Other women use it on their brows and lashes combined, and have noticed a distinct difference in both. Fuller eyebrows, shinier brows and lashes, and no lashes falling out or breakage are some of the improvements consumers have noticed after regular use of RapidLash. One user states that she was going to get eyelash extensions to fill in her sparse lashes, but ended up using RapidLash instead, which worked just as well. Most women reviewed did not experience side effects, though very few say that the product didn’t work as well as they had desired.

    I found Rapid Lash is making my eye lashes to fall off. I notice since the 2nd tube I used. Still I want to give it a try and now I have even more eye-lashes falling off.
