Question 1

What is Rejūv?

Accepted Answer

Rejūv is a copper peptide serum built around GHK-Cu, a naturally occurring tripeptide complex that your body already produces. We paired it with an advanced liposomal delivery system designed to help the peptide reach deeper layers of the skin where it can actually do its work.

Question 2

What's in the formula?

Accepted Answer

The hero ingredient is GHK-Cu (glycyl-L-histidyl-L-lysine copper), delivered via a lipid-based encapsulation system. The supporting formula is intentionally minimal: no harsh fillers, no unnecessary fragrances, no long lists of ingredients you can't pronounce. Full ingredient transparency will be available at launch.

Question 3

Is it fragrance-free?

Accepted Answer

Yes. We chose to leave fragrance out entirely. The formula is designed to work in harmony with your skin, not to mask itself with synthetic scent.

Question 4

What skin types is it for?

Accepted Answer

Rejūv is formulated for all skin types. GHK-Cu is a signaling molecule that works with your skin's own biology rather than forcing a specific response, making it broadly compatible across skin profiles.

Question 5

What is GHK-Cu?

Accepted Answer

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and other bodily fluids. It was first identified in 1973 and has since been the subject of over five decades of peer-reviewed research. Levels of GHK-Cu decline by roughly 60% between the ages of 20 and 80, which correlates with the skin's reduced ability to repair and regenerate.

Question 6

Why does delivery matter?

Accepted Answer

Most copper peptide serums sit on the surface of the skin. GHK-Cu is highly water-soluble, but the skin's outer barrier is lipid-based, meaning the peptide struggles to pass through on its own. Research shows that without an advanced carrier, as little as 0.006% of the applied peptide may actually reach the deeper skin layers. Delivery technology is what bridges that gap.

Question 7

What is liposomal delivery?

Accepted Answer

Liposomes are microscopic lipid-based vesicles that can encapsulate water-soluble molecules like GHK-Cu. Because their outer layer mimics the structure of cell membranes, they can navigate the skin's barrier more effectively, protecting the peptide from degradation and releasing it where it's needed most.

Question 8

Is GHK-Cu safe?

Accepted Answer

GHK-Cu is a molecule your body produces naturally. It has been extensively studied for over 50 years with a strong safety profile documented across human, animal, and in vitro research. As with any skincare product, we recommend a patch test before first use.

Question 9

Who makes Rejūv?

Accepted Answer

Rejūv is an independent skincare brand born from a simple frustration: the gap between what longevity science has proven and what the skincare industry actually delivers. We're a small team focused on formulation integrity and delivery engineering.

Question 10

Where is it made?

Accepted Answer

Rejūv is formulated and produced in the United States. We work with manufacturing partners who specialize in advanced encapsulation technology.

Question 11

When does it launch?

Accepted Answer

We're currently in pre-launch. Join the waitlist to be the first to know when we go live. Waitlist members will receive early access and exclusive launch pricing.

Question 12

What do I get by joining?

Accepted Answer

Waitlist members receive early access to purchase before the general public, exclusive launch-day pricing, and periodic updates on our progress. No noise, just the things that matter.

Question 13

Will my email be shared?

Accepted Answer

Never. Your information stays with us. We don't sell, rent, or share your email with third parties. Period.

Question 14

How will I know when it launches?

Accepted Answer

We'll send you an email the moment we're live. Waitlist members hear first, before any public announcement or social post.
