Exodus GHK-Cu Copper Peptide Prep Serum
$49.00
It takes about sixty seconds.
You have bought things before. This one fits.
Night creams, facial oils, and mineral sunscreens are built to sit on the surface and stay there. That is exactly what you do not want between your skin and the light. The Prep Serum is water-based, absorbs quickly, and leaves nothing behind, so when the session starts, the light reaches your skin the way it is supposed to.
It goes on after you cleanse and before you run the mask. Three to four drops across your face and neck, a short wait, then your session. On a day you skip the light, it layers right under your usual moisturizer. One step, once daily, and it holds its place in your morning without asking much.
The first step, written down.
One bottle. One job. One minute.
The serum. A lightweight, water based cosmetic serum, pale blue in the bottle. It absorbs in about sixty seconds and leaves no film, so it goes on clean skin right before a light session.
The glass dropper bottle. 30 mL (1 fl oz). The dropper is how you count the amount, so there is nothing to measure by eye.
The amount. 3 to 4 drops on face and neck, avoiding the eye area, once daily. That is what the bottle label says.
The step. Prep, then Light, then Radiance. The serum is step 1 of the Radiance System routine. Steps 2 and 3 use products that are sold separately.
Prep. Light. Radiance.
The Face Mask manual gives three steps and says all three take under ten minutes.
1
Prep
Cleanse and pat dry. Apply 3 to 4 drops of Prep Serum to face and neck, avoiding the eye area. Give it about sixty seconds to absorb.
2
Light
Run your session: the Red Light+ Face Mask for the face, 5 minutes maximum, or the Mat for the body. Each device keeps its own limit.
3
Radiance
Finish with a pass of Frequency Mist+ Radiance across face and neck. The mask and the mist are sold separately, or together with the serum as the Radiance System.
What the first step gives your routine
The amount is already decided
check_circle
The label says 3 to 4 drops. The manual says once daily. You do not have to figure out how much or how often, which means one less reason to skip it.
About sixty seconds
check_circle
That is the wait between the serum and the light, built into the routine rather than added to it. Long enough to set your device out, short enough that the routine still fits your day.
Nothing sits between the light and your skin
check_circle
Night creams, facial oils and mineral sunscreens are built to sit on the surface and stay there. This serum is water based and absorbs quickly, leaving no film. That is why it goes on before the session, not after.
A no-session day routine
timer
On a day with no session, apply it the same way and follow with your usual moisturizer. One habit, whether the mask is on the schedule or not.
Safe with Light Code devices
health_and_safety
It contains no heating agent, so it is safe to use with any Light Code device. One bottle goes before the Face Mask or the Mat.

Read more about the routine
Six minutes before anyone else is up.
The house is quiet. The dog can wait one more minute. Your face is clean and dry, the towel is back on its hook, and the bottle is where you left it on the shelf.
You draw the dropper up. The serum is pale blue. Three drops, then a fourth, across your face and down your neck, nowhere near your eyes. Then you wait about sixty seconds. Not scrolling. Not answering anything. Just standing in the quiet while it absorbs.
Then the mask goes on. Five minutes, no more, the way its own manual says. You sit with your coffee and let it run.
You are not doing this because someone promised it would fix something. You are doing it because it is yours. The 9 a.m. call is still an hour away. You were here first.
The question behind the serum.
The common question: What is in the serum?
The better question: What is sitting between your face and the light?
The Face Mask manual puts it plainly: anything sitting on the surface of your skin is something the light has to get through first. Night creams, facial oils and mineral sunscreens are built to sit on the surface and stay there.
The Prep Serum is made for the minute before a session. It is lightweight and water based, it absorbs quickly, and it leaves no film between the LEDs and your face. That is why it is the first step, and why the manual calls it the step that gets skipped.
Sixty seconds before the light
The kettle is on. You have maybe twelve minutes before the 9 a.m. call, and this is the morning you do not skip it.
You wash your face, press three or four drops into your face and neck. You count to sixty while the kettle finishes.
By the time you sit down with the mask, the serum is gone. You did not add a step. You added a beginning.
What this is, and what it is not.
The Prep Serum is a cosmetic skincare product: a lightweight, water based serum in a 30 mL glass dropper bottle. It goes on clean skin before a light session. That is what it is.
It is not a medical device and not a quick fix. We make no claim about what it does for your skin. It is for adults and for external use only. Keep it away from your eyes, and patch test first if your skin is sensitive. If you are pregnant, nursing or under a dermatologist's care, check with them first.
If you want a before-and-after, this is not it. If you want the first step of your light routine written down, it may be the right fit. You have been sold promises before. We would rather tell you exactly what this is and let you decide than tell you what you want to hear.

Why Exodus Strong exists
He is healthier at 58 than he was at 44.
Rob Rene is 58. He survived a Stage III melanoma diagnosis and five near-death experiences, and he is healthier now than he was at 44. That is why Exodus Strong exists. His story is his own. It is not a promise about this bottle.
In the manual he writes: "More is not better. Consistency is what carries this."
He built the company around one idea. A device is only as good as the routine that comes with it. The Prep Serum is part of that routine: the first of three steps, with the amount and the wait written down. 3 to 4 drops. About sixty seconds. Once daily.
He made it simple because simple is what gets kept. Rak Chazak.
One glass dropper bottle of Prep Serum. 30 mL (1 fl oz). The serum is pale blue.
Also included: nothing digital.
Not in the box: the Red Light+ Face Mask, Frequency Mist+ Radiance, the Mat, or any other Light Code device. Those are sold separately, or together as the Radiance System.
Your choice. $49 as a single payment, or $39 delivered every month, or every two months, with Subscribe and Save. No subscription is required to buy, and you can skip, change or cancel any time from your account.
Is there a real person I can talk to?
Yes. Call 972-777-5556 or email Support@ExodusStrong.com and you will reach a real person. If your bottle arrives missing or damaged, contact us before first use.
How does the guarantee work?
Every Exodus Strong product has a 60-day money-back guarantee. If the Prep Serum is not for you, contact us inside 60 days for a full refund.
How much do I use?
3 to 4 drops, on face and neck, avoiding the eye area. That is what the bottle label says. Use it once daily. Once daily is plenty.
When do I put it on?
On clean, dry skin, right before a light session. Cleanse and pat dry, apply the serum, give it about sixty seconds to absorb, then run your session.
What about a day with no session?
Apply it the same way, on clean and dry skin, and follow with your usual moisturizer. Once daily is plenty, whether a session is on the schedule that day or not.
Why before the light and not after?
Anything sitting on the surface of your skin is something the light has to get through first. The serum is water based, absorbs in about a minute and leaves no film between the light and your face. Night creams, facial oils and mineral sunscreens are built to sit on the surface.
Do I need the Face Mask to use it?
No. The manual's second step is the Face Mask for the face or the Mat for the body. It also gives a no-session day: the serum, then your usual moisturizer.
Is it safe to use with my device, and how long is the session?
Yes. It contains no heating agent, so it is safe to use with any Light Code device. The session length is the device's own limit, not the serum's. The Face Mask is 5 minutes maximum, 3 days a week for 8 weeks, never more.
What is in it, and is it a medical product?
Ingredients are listed on the bottle and at ExodusStrong.com. It is a cosmetic skincare product, not a medical device. The serum itself is lightweight, water based and pale blue.
Is it safe for me?
It is for external use only, and for adults only. Avoid direct contact with the eyes. Patch test before your first full use if your skin is sensitive, and discontinue use if irritation occurs. If you are pregnant, nursing or under a dermatologist's care, check with them before adding it. Keep it out of reach of children.
How should I store it?
Store it at room temperature, out of direct sunlight, and keep it out of reach of children. That is the whole care instruction in the manual.
