The goal is for people to say you look rested, not ask who did your lips.
Every plan at ZK starts with a consultation, an honest price, and the option to start small.
Restraint over volume
The smallest dose that does the job. You can always add at a follow-up.
Assessment first
Muscle strength, bone structure and how you move are mapped before anything is drawn up.
The injector matters
Placement and depth matter more than brand, so Cassie does every treatment herself.
Subtle over noticed
You should look like yourself on a good week.

Questions
Before you book
Will I look frozen or overdone?
Not if the dose is right. Cassie doses to soften lines while keeping your expressions, and would rather add a little at a follow-up than overdo it on day one.
Is the consultation really free?
Video consults are free. In-person consults are $75, and that amount is credited toward your treatment if you book.
Who does my treatment?
Cassie does. ZK is a one-provider practice, so the person you consult with is the person who treats you every time.
Does the membership lock me in?
No. The Glow Society is $49 a month and you can cancel anytime. Ask at your visit for the current terms.
