Eyelashes are said to appear more voluminous and maximized, with eyebrows healthier looking. Keep reading this review for more about this lash and brow growth serum product such as the ingredients, how to use this product, the price and the guarantee offered.


There are only two (2) key ingredients in this product’s formula: Amino acids offer key nourishment, whereas the botanical ingredient red clover provides antioxidants that assist to defuse free radicals. No data on the concentration of the active ingredients are provided by the manufacturer. What is expected is no less than a 10% concentration of the active components, for a formula to be effective. Furthermore, the inclusion of ingredients is limited. This is a concern: for a product to be effective, it needs at least five patented, clinically proven ingredients.

How To Use

Application instructions are clear and easy to grasp. At night, all make-up must be carefully removed, together with contact lenses, if worn. The product, a liquid eyeliner, should be applied with the brush provided, in the direction of hair growth.


A 15-fluid ounce bottle of this product is available online, directly from the manufacturer at $36.00. No discounts nor bundle deals are available for the end user. If such incentives were offered it would not only have rewarded loyal clients but would have saved the end user a lot of money over a long period.

Guarantee & Feedback

Although the manufacturer offers a guarantee to back this eyelash and eyebrow growth product, the terms and conditions of the pledge are unclear. Consumers are not told how many days they have in which to return the product nor the condition in which it must be returned. There are a few reviews given, mostly positive.

Our Conclusive Review About Mary Kay Lash & Brow Building Serum

The product Lash & Brow Building Serum appears useful to those wishing to improve the condition of their eyebrows and eyelashes, helping them grow longer and stronger. This beauty product is underpinned by a money-back guarantee and a clear instruction guide which could lead to optimal results. There are also certain negative aspects to this eyebrow serum. A concentration of at least 10% of the active ingredients and at least five patented ingredients should be included. The manufacturer of this eyelash and eyebrow growth product fails to offer the consumer any discounts nor even any package deals saving money in the long run and rewarding loyal patrons. There are many other, similar eyelash and eyebrow conditioning products on the market offering better quality ingredients, a higher concentration of active ingredients, attractive package deals and discounts, also a solid guarantee that protects the consumer. It is noteworthy that clients read appraisals to determine the unseen facts that manufacturers will hide from the consumer so that they can make informed choices.
