Common questions about Rodan + Fields Lash Boost
How do I use Rodan + Fields Lash Boost with my Regimen?
Remove your makeup. Then wash your face with your Rodan + Fields Regimen Wash. Eyes should be completely clean and dry. Apply Rodan + Fields Lash Boost as directed and wait at least 90 seconds for the product to completely dry. Follow with the remaining Regimen Steps 2-4, avoiding the eye area.
Is Rodan + Fields Lash Boost safe for my eyes?
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.
Can Rodan + Fields Lash Boost also be used on my eyebrows?
Rodan + Fields Lash Boost can be applied to eyebrows to help them appear healthier looking and more beautiful. Apply Rodan + Fields Lash Boost nightly to clean and dry eyebrows. Do not wash your face after you apply Rodan + Fields Lash Boost to your eyebrows.
Can I use Rodan + Fields Lash Boost if my eyeliner is tattooed?
Rodan + Fields Lash Boost is suitable for use if your eyeliner is tattooed.
Can Rodan + Fields Lash Boost be used on the lower lash line?
Do not use on the lower lash line. Applying Rodan + Fields Lash Boost on both the upper and lower lashes could lead to irritation in the eye area.
Can I use Rodan + Fields Lash Boost if my eyelashes or eyebrows are tinted?
Rodan + Fields Lash Boost is suitable for tinted eyelashes and eyebrows and will not affect the color.
