Frequently Asked Questions
Will lash serum change my eye color?
This is a valid concern, particularly with formulas containing prostaglandin analogs. While color change is rare, it is a documented side effect of certain medicated lash treatments that can increase iris pigmentation. If you have light-colored eyes, you might want to stick with peptide-based serums that do not carry this specific risk.
Can I use these serums with lash extensions?
You should generally avoid oil-based serums if you wear extensions, as the oil can break down the adhesive bond. However, water-based, oil-free formulas are often safe to use. Always check with your lash technician first, because their specific glue might have unique compatibility requirements.
What happens when I stop using the serum?
Your lashes will eventually return to their natural growth cycle once you stop the daily applications. This usually happens over a period of four to eight weeks as the old, longer lashes shed. Think of it like stopping a workout routine: the benefits fade once you cease the maintenance phase.
Can I apply serum to my bottom lashes?
Most experts advise sticking to the upper lash line only. When you blink, the product naturally transfers to the bottom lashes without the risk of direct application, which often leads to irritation or dark circles under the eyes. Applying to the top is enough to achieve a fuller look overall.
Are these serums safe for contact lens wearers?
You should remove your lenses before applying any serum to avoid trapping chemicals against your eye. Wait at least fifteen minutes after application before putting your contacts back in. This gap ensures the formula has fully absorbed into the skin, preventing any cloudy residue or discomfort.
