What is lash serum?
Lash serums are beauty products specifically designed to improve the appearance of eyelashes and eyebrows. They contain a blend of nourishing ingredients such as peptides, biotin, and keratin that help promote healthy-looking lashes and brows. These ingredients are applied to the upper lash line and brow line once daily to help strengthen and condition the lashes while providing a boost of hydration. With consistent use, lash serums can help promote the appearance of longer, stronger and darker-looking lashes.
Do eyelash serums really work?
Each eyelash serum formulation offers varying results, but we can speak to the effectiveness of R + F Lash Boost. In a U.S. clinical and consumer study involving real participants who used the product for eight weeks, 90% experienced fuller-looking lashes, 85% experienced longer-looking lashes, and 63% experienced darker-looking lashes. We also have over 8,000 five-star reviews from customers who have reported major improvements in the appearance of their lashes and brows with regular use.
Keep in mind that results may vary depending on multiple factors: age, gender, skin type and condition, concomitant products used, health history, location, lifestyle and diet.
How does lash serum work?
Lash serums contain a blend of nourishing ingredients that help promote healthy-looking hair. These ingredients improve lash durability by providing proper moisture and breakage protection. They also act as a conditioner for your brows and lashes, helping to achieve the appearance of greater definition, improved fullness, and a more youthful appearance.
Are lash serums safe?
Rodan + Fields philosophy is to create safe and beautifying formulations. We would not place a product on the market that does not meet our standards. Rodan + Fields Lash Boost has been found to be well tolerated and non-irritating for the great majority of users. However, if you think you might have a skin or eye sensitivity, we recommend conducting a patch test: after making sure your eyelids are clean and free of make-up, apply a small amount of Lash Boost to a portion of the eyelid margin near the upper eyelash line of one eye. if the eyelid skin appears normal and the eye shows no redness or irritation after 24 hours, then apply Lash Boost as directed but begin with a reduced frequency (e.g., every other day) for several days and gradually increase to every day, while monitoring for any tolerance issues. In some cases, the product may be better tolerated with a reduced frequency of application. if redness or irritation returns despite a reduction in frequency of application of the product, discontinue use of the product and consult with a medical professional.
How long does it take for lash serums to work?
The exact amount of time it takes to see results will vary depending on the product and your individual lashes. However, most people can start to see visible improvements in lash length and fullness after 8-10 weeks when used as directed.
For best results, use lash serum regularly as part of a nightly beauty routine — this will help ensure that you get the maximum benefits from the product. Less frequent use may still provide some benefits, but it may take longer to see results.
