Exodus Copper Peptide Prep Serum

Serum goes on before the light, not after.

The Copper Peptide Prep Serum is a lightweight, water-based serum you apply to clean skin right before a red light session. It absorbs in under a minute and leaves no film between the LEDs and your face, unlike the night creams, facial oils, and mineral sunscreens that are built to sit on the surface. The formula is Copper Tripeptide-1, the copper peptide also known as GHK-Cu, carried in a hydrating base of Sodium Hyaluronate and Glycerin. Nine ingredients total. No fragrance, no oils, no parabens. 30 mL, in a glass dropper bottle. $39, with a 60-day money-back guarantee.

How the 3-step Radiance ritual works

1. Prep. Wash your face, pat dry, then press three or four drops into clean skin on face and neck. Give it sixty seconds to absorb.
2. Light. Put the Red Light+ Face Mask on and rest for 10 to 15 minutes. Pray, listen to worship, or simply be still.
3. Radiance. Finish with a pass of Exodus Frequency Mist+ Radiance on face and neck.

Three steps. Fifteen minutes. The serum is step one, and it is the step most people skip.

Why a thin serum instead of your night cream?

Because of what is left sitting on your skin when the mask goes on. Night creams, balms, facial oils, and mineral sunscreens are built to stay on the surface and hold moisture in. That is exactly what you want at bedtime, and exactly what you do not want under an LED mask. This serum is built for the opposite job. Water is the first ingredient, there are no oils in it at all, and it absorbs and leaves clean, hydrated skin behind.

What is copper peptide, and why is the serum blue?

Copper Tripeptide-1, written in most research as GHK-Cu, is a small chain of three amino acids bound to copper. It has been used in skincare for decades and it is the reason this bottle is pale blue. That colour is not a dye. Copper complexes are blue in solution, so the tint is the ingredient showing itself. In a cosmetic formula it is included to support a hydrated, firmer-looking complexion. The evidence on topical copper peptides is promising but still limited, which is why we describe it in terms of how skin looks and feels rather than promising more than that.

It is carried in a deliberately short hydrating base. Sodium Hyaluronate is the salt form of hyaluronic acid, small enough to sit well in a light serum, and Glycerin is the humectant that has anchored good moisturizers for a century. Both are studied humectants that attract and hold moisture, leaving skin feeling softer, smoother, and more supple. That is the whole job of a prep step.

The full list is nine ingredients. There is no fragrance in it, no essential oils, no alcohol, no parabens, and no silicones. That is not marketing restraint, it is what a serum has to look like if it is going under a mask.

Who is this serum for?

It was built for anyone already running red light on their face, whether that is the Red Light+ Face Mask, the full Radiance System, or another LED device entirely. It is also for the person who wants a simple, uncrowded serum: one recognizable active, a hydrating base, and nothing else competing for room on the label. It is a cosmetic product for adult skin. If you are pregnant, nursing, or under a dermatologist's care, check with them before adding any new active to your routine.

How do I use it?

On clean, dry skin, press three or four drops into your face and neck and let it absorb for about a minute before the mask goes on. Once daily is plenty. On a day you are not running a light session, apply it the same way and follow with your usual moisturizer. Patch test on your inner forearm first if your skin runs sensitive.
