Made by lash artists. For everyone who loves their lashes.
For over 11 years, Katie has been Bethesda's go-to for natural-looking lashes and skincare. After watching too many clients struggle with harsh, prostaglandin-based serums that caused irritation and dark circles, she set out to create a better one.
The result is Katie's Brand — a line of formulas built on what actually works in the salon, with none of the ingredients we'd never use on a client.

Frequently Asked
What makes Katie's Brand different from other lash serums?
Most lash growth serums use prostaglandins (like Latisse) which can cause iris pigmentation, dark circles, and irritation. Our formula is 100% prostaglandin-free and hormone-free, using peptides, biotin, and botanical extracts to safely grow lashes without side effects. It's the same formula trusted in our Bethesda salon for years.
