Frequently Asked Questions
Do these serums actually change my eye color?
There is a small risk of iris pigmentation if you use serums containing prostaglandin analogs, specifically if the product gets inside the eye. This side effect is more common in people with lighter-colored eyes. If you are worried about this, look for peptide-based formulas that do not contain these specific chemicals.
Can I use lash serum while wearing eyelash extensions?
Yes, but you must ensure the serum is oil-free. Oils can break down the adhesive bond, causing your extensions to fall out prematurely. Always verify with your lash technician that the ingredients in your chosen serum won't interfere with their specific glue.
What happens if I stop using the serum?
Your lashes will eventually return to their natural length and thickness once you stop the treatment. Because the serum forces lashes to stay in the growth phase longer, stopping the supply means the lashes will shed and be replaced by new, untreated hairs. Think of it as a maintenance routine rather than a permanent fix.
Is it safe to apply serum to my bottom lashes?
Most experts advise against this, as the product can easily migrate into your eye when you blink. The serum will naturally spread to your lower lashes when you close your eyes at night, which is enough to provide some conditioning benefits. Applying it directly to the bottom line usually just leads to unwanted redness.
Should I apply the serum in the morning or at night?
Nighttime application is generally better because it allows the serum to absorb while your eyes are closed and resting. Ensure your face is clean and dry before you apply the product to avoid trapping makeup or debris in the follicles. Applying it as part of your evening ritual helps build the consistency needed for real results.
