mixsoon Bean Copper Peptide Firming Serum — 30ml dual-phase with 2% Niacinamide for firmer, smooth-looking skin

mixsoon Bean Copper Peptide Firming Serum is a dual-phase Korean face serum that blends copper tripeptide-rich oil with a fermented bean essence and 2% niacinamide for firmer-looking, smooth-feeling skin.

This lightweight, dual-layer serum is formulated to combine the stabilizing benefits of copper peptides with a fermented bean complex and a 2% niacinamide boost. Shake to emulsify the two phases before application: a nourishing oil layer and a water-based essence. The result is a silky, non-sticky texture designed to absorb quickly into skin and layer easily under moisturizers or sunscreen, suitable for both morning and evening skincare routines.

How should I use this dual-phase serum in my routine?

Shake the bottle well to mix the oil and essence, then dispense 2–3 drops. Gently pat over cleansed face and neck, allowing it to absorb before following with moisturizer and SPF in the morning or a richer cream at night.

• Shake to blend the oil and water layers for even delivery.
• Use after toner and before heavier creams or sunscreen.
• Apply 1–2 times daily depending on tolerance and skin needs.
• Pat gently rather than rubbing to encourage absorption.

What active ingredients are in it and what do they do?

The formula pairs copper tripeptide-1 with a fermented bean extract and 2% niacinamide for multi-functional support. Copper peptides are included for their role in skin conditioning, while fermented botanicals help with nutrient delivery and niacinamide supports an even-looking, balanced complexion.

• Copper tripeptide-1 (GHK-Cu): copper peptide complex for visible skin conditioning.
• Fermented bean complex: helps the skin feel hydrated and supple.
• 2% niacinamide: supports smooth-looking, balanced skin tone and texture.
• Light carrier oils: create a silky finish without heavy residue.

Will this serum feel heavy or leave a sticky finish?

No — the design aims for a lightweight, silky texture that absorbs cleanly into skin. The dual-phase system allows a nourishing oil veil without greasiness, so it layers well under makeup and sun protection.

• Silky, fast-absorbing finish that avoids tackiness.
• Suitable for use before makeup and sunscreen application.
• Formulated for daily morning and evening use.
• Minimalist ingredient philosophy to reduce unnecessary fillers.

Who is this for: mixsoon Bean Copper Peptide Firming Serum is intended for people looking for a lightweight, K‑Beauty style daily serum that combines peptide support, fermented botanical nourishment, and niacinamide to promote firmer-looking, smooth-feeling skin. It is suitable for most skin types seeking a non-greasy texture that layers well with typical skincare steps; those with very reactive skin should patch-test first.
