Three Bottles of Zephyrian for FREE, And a Lifetime Discount

We have a few spots left in our Get Free Zephyrian campaign!

The feedback we have received for Zephyrian over the past few months has been awesome. Even better than we could have imagined beforehand. (Read our reviews)

That’s why we want to gather some numerical data, and we are looking for participants for a pilot study.


To apply for the study, fill out the application at the bottom of this page.


Hox! For maximum transparency and integrity of the study, only new customers (no orders yet) are eligible to apply.

1. Use Zephyrian for 90 days


Take Zephyrian with the fattiest meal of the day for maximum absorption.

It's essential. The active ingredients are fat-soluble, so they must be taken with a meal that includes some fat (lunch or dinner is ideal). The ingredients will not be absorbed on an empty stomach.


2. Take Progress Photos

Once a month (after 30 days, after 60 days, and after 90 days). We’ll remind you with an email.

Lighting changes how your skin looks on camera. Using the same window or screen flash each time keeps brightness and colour the same, so only your skin’s changes show. That makes your before-and-after photos fair and easy to compare.


Photo Instructions

Graph with carotenoids and melanin axes, colored dots, and text annotation.

3. The Results

After 90 days:

1. Post the Before&After pictures and a written review on our website (we’ll remind you with an email)

2. Answer the test group survey (it takes around 3 minutes)
