Inside our formulas

Copper complex
GHK-Cu pairs copper with a very short chain of three amino acids, a combination that also occurs naturally in the body. In skincare it has become one of the best-known names in firming formulas. In Cu Restore it sits at the heart of the serum, chosen for skin that looks firmer, smoother and more rested.

Moisture binder
Hyaluronic acid is a moisture-binding ingredient that holds water at the surface of the skin. The result is a hydrated, plumper look and a smooth, comfortable feel. Because it is light and works well with almost everything, it appears in both Cu Restore and Lumière.

Brightening classic
Vitamin C is one of the most familiar brightening ingredients in skincare, valued for a fresher, more radiant-looking complexion. It belongs in the morning step of a routine, always followed by sunscreen. In Lumière it works alongside arbutin, hyaluronic acid and ceramides.

Tone evener
Arbutin is a plant-derived ingredient, found in leaves such as bearberry, that is widely used to help even the look of skin tone and dark spots. Combined with vitamin C in Lumière, it makes a gentle, everyday brightening step.

Barrier lipids
Ceramides are lipids that make up a large part of the skin’s outer layer, the part that keeps moisture in. Picture bricks and mortar: ceramides are part of the mortar. In Lumière they help skin feel smooth, soft and comfortable through the day.

Night trio
Nocturne brings together three ingredients with an evening character: melatonin, closely tied to the body’s night-time rhythm; apigenin, a flavonoid found in plants such as chamomile; and GABA, an amino acid. The result is a calming serum made for the last step before sleep.

Line smoother
SNAP-8 is a cosmetic ingredient developed with expression lines in mind, the fine lines that form where the face moves most. In Cu Restore it joins GHK-Cu and hyaluronic acid for skin that looks smoother and more even.

Our approach
Naxgen Labs keeps the routine short on purpose. Each serum is built around a small group of well-known ingredients, printed clearly on the label, so you always know what you are putting on your skin.
Use one serum on its own, or pair a morning and an evening serum into a simple daily ritual.
Skincare, simply explained
A serum is a lightweight, concentrated formula made to deliver a small group of key ingredients in a texture that absorbs quickly. Where a moisturizer is mostly about comfort and sealing in hydration, a serum is the step that carries the ingredients you choose for a specific goal: brightness, firmness or a calmer feel.
Because the texture is thin, a serum goes on right after cleansing, before heavier creams. Two to three drops are enough for the face and neck.
Each Naxgen serum has a single, clear purpose. Lumière is the brightening step for the morning. Cu Restore is the firming, smoothing step you can use morning or night. Nocturne is the calming step for the end of the day. Clear roles make it easy to see what each bottle does and when to reach for it.
Start with the serum that matches your main goal, then add a second one for the other half of the day.
Skincare rewards routine. A short ritual you follow every day will do more for the look of your skin than a long one you skip. That is why our rituals use two or three steps, morning and evening, built around one serum each time.
Finish every morning with sunscreen, give new products a patch test, and give your routine a few weeks before judging the results.

The questions we hear most often about our serums, shipping and returns.
All questionsChoose by your main goal. For a brighter, more even look, start with Lumière in the morning. For skin that looks firmer and smoother, start with Cu Restore. For a calm, comfortable feel at night, start with Nocturne. Our Rituals page shows simple pairings.
Yes. A full routine is Lumière in the morning, then Cu Restore and Nocturne in the evening. Apply each to clean skin and let it absorb for about a minute before the next step.
Two to three drops cover the face and neck. Using more does not make a serum work faster; it simply takes longer to absorb.
