coxir EGF Peptides Serum for Face 50ml — GHK-Cu Copper Peptide + Niacinamide for Firming & Even Tone

coxir Intensive EGF Peptides Serum is a lightweight Korean peptide serum that combines EGF, GHK-Cu copper peptide, niacinamide, and adenosine to support firmer, more even-looking skin.

This 50 ml (1.69 fl. oz) serum blends an EGF + 7-peptide renewal complex with Copper Tripeptide-1 (GHK-Cu), niacinamide, and adenosine in a fast-absorbing formula designed for daily layering. It aims to improve skin texture and tone while feeling weightless under moisturizer and makeup. The formula is free from parabens and silicones, cruelty-free, and tested for sensitivity, making it suitable for many skin types seeking visible resilience and radiance without heavy residue.

How will this serum fit into my morning and evening routine?

Use after cleansing and toning, applying just a few drops to damp or dry skin, then press gently until absorbed. It layers well under moisturizers, sunscreens, and makeup for daytime, and pairs with richer creams at night to support overnight renewal.

• Apply 2–3 drops after toner, morning and night.
• Pat into face and neck until fully absorbed.
• Follow with moisturizer and SPF in the morning.

What active ingredients are included and what do they do?

The formula combines EGF and a seven-peptide complex with Copper Tripeptide-1 (GHK-Cu) for multi-targeted peptide support, plus niacinamide and adenosine to address tone and skin resilience. Together these ingredients focus on improving texture, promoting a firmer feel, and evening the complexion without heavy oils.

• EGF + 7-peptide complex: peptide support for surface firmness and bouncy texture.
• GHK-Cu (Copper Tripeptide-1): peptide type aimed at plumping fine lines and supporting elasticity.
• Niacinamide: helps even skin tone and strengthen the skin barrier.
• Adenosine: supports smoother, more resilient-looking skin.

Is this serum suitable for sensitive or combination skin?

The formula is labeled sensitive-friendly and has been tested for irritation; it’s free from parabens and silicones and designed to be lightweight rather than greasy. However, patch testing is recommended, especially if you have reactive skin or use other active treatments.

• Clean formulation without parabens, silicones, or harsh chemicals.
• Dermatologically sensitivity-tested for milder response.
• Lightweight texture that layers well for combination skin.

How quickly will I see results and how should I store it?

Visible changes to texture and tone can vary by individual; many users notice softer-feeling skin and improved layerability within days, while firmer-looking texture may take several weeks of consistent use. Store in a cool, dry place away from direct sunlight to maintain ingredient stability.

• Expect immediate improvements in hydration and skin feel.
• Consistent use over weeks for more noticeable texture or firmness differences.
• Keep bottle tightly closed; avoid prolonged heat or light exposure.

Who is this for: coxir Intensive EGF Peptides Serum is intended for anyone looking to add a peptide-forward, lightweight renewal step to their skincare routine — ideal for those wanting firmer-feeling skin, a more even tone, and an easily layered product that works under makeup and sunscreen. It suits people with normal, combination, and many sensitive skin types who want daily peptide support without heavy emollients.
