How Does the Formula Function to Support Lashes?

The formula functions by mimicking the action of naturally occurring compounds in the body that signal hair growth. This action conditions the lash follicle, supporting the lash's natural growth cycle and helping the lash appear darker and longer over time.

What is the Difference Between Prostamide and Peptide?

Prostamide formulas are chemical analogs with drug-like effects that significantly alter the growth phase. Peptides are amino acid chains that are conditioning ingredients, offering a gentler, less potent effect on lash appearance.

What are the Potential Side Effects?

Potential side effects, though less common than with prescription formulas, can include eye irritation, redness, or a darkening of the skin around the application area. Users should monitor closely and consult a doctor if irritation occurs.

Why is Precise Application Necessary?

Precise application is necessary to prevent the product from migrating. Like other potent lash serums, the formula should only be applied to the base of the upper lash line to avoid contact with the tear film and lower eyelid skin.

How Does This Formula Affect Contact Lens Wearers?

This formula affects contact lens wearers because the product can transfer into the eye. Contact lenses must be inserted only after the serum has completely dried, as absorption of the ingredients can lead to lens discomfort or fogging.

FAQs on Prostamide Formula

Are all non-prescription serums safe?

Users should always check ingredients and choose ophthalmologist-tested products, as some potent compounds can still cause irritation.

Do these formulas cause eye irritation?

Yes, if they migrate into the eye, they can cause temporary stinging and redness due to their chemical nature.

How long do I use the serum for?

Visible results typically require consistent, daily use for six to twelve weeks.

When to See Your Doctor

Many non-prescription serums contain "Prostamides." If your eyelids look dark or "sunken" (Periorbital Fat Atrophy), stop use. This is a side effect of prostamides that can be permanent. A doctor should evaluate any changes to the skin or orbital fat.
