FAQ
Reader questions
Can I use lash serum while wearing lash extensions?
Yes, choose a lightweight serum and apply sparingly at the base of natural lashes to avoid adhesive breakdown. Extensions still require regular fills and professional aftercare.
Will these serums work if I have naturally short lashes?
They can enhance the appearance of length and density by improving lash health, but genetic lash length has limits. Realistic expectations help align results with your natural features.
How often should I reorder my favorite serum?
Most standard-sized serums last two to three months with nightly use. Set a reminder to repurchase before you run out to maintain consistency in your routine.
Is it safe to layer lash serum with my regular mascara?
Apply serum at night and mascara in the morning after lashes are fully dry. This sequence prevents buildup on the brush and keeps both products effective.
