Frequently Asked Questions
Can I use my eyelash serum on my eyebrows?
You generally can, provided the formula is safe for the eye area. However, brow hair is coarser than lash hair, so some products designed specifically for brows contain thicker consistencies or higher concentrations of active ingredients to penetrate the skin better.
What happens if I stop using the serum?
If you stop your routine, your brows will eventually return to their natural growth pattern. Any newly grown hair will likely shed over time as the follicle goes back to its baseline state. Consistency is key to maintaining your progress.
Is it safe to apply makeup over the serum?
Yes, but you must let the serum dry completely first. Wait about two to five minutes before applying any brow gel or pencil to prevent the products from mixing and becoming gummy.
Will these serums change my eye color?
This is a rare side effect primarily associated with certain medical-grade prostaglandin analogs used in lash serums. Most over-the-counter brow serums use peptide-based formulas that do not carry this specific risk, but check the ingredient list for prostaglandins if you are concerned.
How often should I apply the product?
Most experts recommend applying it once daily, usually at night after washing your face. This gives the ingredients plenty of time to absorb into the skin while you sleep without being disturbed by sweat or friction.
