COSRX 6X Peptide Skin Booster Mini Toner-Serum 1.01 fl oz — Travel Size with GHK-Cu for Firmer, Radiant Skin

COSRX Mini 6X Peptide Skin Booster is a travel-sized toner-serum that preps and firms skin with a lightweight, fast-absorbing formula featuring six peptides and copper peptide GHK-Cu.

This compact 1.01 fl oz edition delivers the same peptide-rich technology as COSRX’s full-size 6X Peptide Skin Booster Serum in a convenient trial or travel format. It’s designed to sit early in a routine with a toner-like texture that layers easily under hydrators and creams. The formula emphasizes peptides and GHK-Cu (a copper peptide) to support skin resilience, texture, and visible radiance without heavy oils or sticky residues.

How will this mini serum fit into my daily skincare routine?

Use this toner-serum after cleansing and before heavier treatments or moisturizers. Its thin, fast-absorbing texture makes it an ideal first treatment step to help subsequent layers penetrate and perform better. Two to three pumps typically cover the face and neck.

• Apply after cleansing and optional exfoliation.
• Dispense 2–3 pumps and press evenly across the face and neck.
• Follow with essences, serums, moisturizers, and sunscreen in the daytime.

What key actives are in the formula and what do they do?

The booster centers on a complex of six peptides plus GHK-Cu (a well-known copper peptide). Peptides are short amino acid chains that support the appearance of firmness and help improve skin texture. GHK-Cu has been included to assist with skin renewal and surface health as part of an overall routine.

• Six-peptide blend to target elasticity, texture, and fine lines.
• GHK-Cu (copper peptide) supports renewal and surface conditioning.
• Light, water-like base for quick absorption and easy layering.

Can I travel with this mini and is it safe for sensitive skin?

The 1.01 fl oz size is airport-friendly and made for travel or trying the product before committing to a full bottle. The lightweight, non-greasy texture reduces the chance of pore-clogging, but people with reactive skin should patch-test new actives. Avoid contact with open wounds and discontinue if irritation occurs.

• TSA-compliant size for carry-on convenience.
• Gentle, fast-absorbing base suitable for layering with soothing products.
• Patch-test recommended for highly reactive or allergy-prone skin.

Which products pair well with this peptide booster?

This booster is formulated to complement hydrating essences and targeted treatments. COSRX recommends pairing it with the Snail 96 Essence for hydration and the Retinol 0.1 Cream for renewal in nighttime routines. Layering helps create a balanced regimen addressing hydration, texture, and tone.

• Use before COSRX Snail 96 Essence for added hydration support.
• Layer prior to moisturizer and sunscreen in daytime routines.
• Combine with retinoids at night, introducing slowly to minimize sensitivity.

Who is this for: This COSRX Mini 6X Peptide Skin Booster suits anyone looking to test a peptide-forward toner-serum or needing a compact skincare step for travel. It’s aimed at people who want a light, easily layered treatment to address elasticity, texture, and overall skin condition while maintaining a streamlined routine. Avoid use if you have known sensitivity to peptides or copper complexes, and consult product ingredient lists if you have specific allergies.
