Mary Kay Lash & Brow Building Serum is a product designed to improve the overall appearance of lashes and brows. The manufacturer states that it will maximize volume and that users will see results in 30 days. We have reviewed this product to determine if it can live up to these claims and assessed factors which contribute to the product quality. The aim of this review is to equip you with the knowledge to make a wise consumer purchase.
This product contains a patented ingredient called Lash Response which is made up of amino acids and Red Clover Extract. The body uses amino acids for many important functions. Red blood cells deliver nutrients to the hair follicles which encourages growth. The use of amino acids can help speed up and strengthen this process. Red Clover Extract is known to increase the strength of hair as well as adding volume. It, therefore, promotes hair resilience and combats the damaging effects of external aggressors. The fact that this formula contains a patent is positive to note as it suggests that it is of a high quality. That said, many competitor products contain up to 5 patented ingredients for improved results. Furthermore, the manufacturer does not stipulate what amino acids are found in this blend or the concentration of active ingredients. We were disappointed to note that the manufacturer does not clearly state if they are cGMP certified. This is worrisome as these certifications are an indication that quality is a priority during production.
The manufacturer states that users should apply this product at night after removing all makeup and taking out contact lenses. The product should be applied in the same way you would a liquid eyeliner along the lash line. The formula should be applied to sparse or bare areas of the eyebrows in the direction of the hair growth. They have failed to indicate the concentrations of the active ingredients, therefore, we cannot accurately gauge the potency of this product. Individual testing will need to be done to determine the best results, however, this can only be done after making a purchase.
Potential customers can purchase this product online from Mary Kay. A 0.15 oz. tube will cost you $36. This is quite expensive when compared to competitor products on the market. The fact that the formula does not contain additional patented ingredients brings the price into question. There are several more affordable alternatives on the market that have superior formulas and these may prove to be a wiser consumer purchase.
Mary Kay offers a Satisfaction Guarantee for purchases of this product. While the inclusion of the guarantee is positive to note, it is vague as to what condition a product needs to be in to be eligible for a refund. The lack of clarity brings the credibility and reliability of this guarantee into question. We were also concerned to note that a few customers were very unhappy with results. They claimed that it did not work as intended. This indicates that results are subjective and not guaranteed.
Mary Kay Lash & Brow Building Serum Review – Conclusion
Mary Kay has produced an appealing product. It contains a beneficial patented ingredient and purchases are supported by a guarantee. That considered, the guarantee does not provide clear return guidelines and this brings its credibility into question. There are a number of alternatives with more patented ingredients for improved results. And, there are cheaper options to consider that will deliver optimal benefits. For these reasons, we cannot recommend this product as the best lash and brow serum on the market.
