COSRX 6X Peptide Collagen Skin Booster Toner-Serum 5.07 oz — Lightweight GHK-Cu formula to firm and smooth

COSRX 6X Peptide Collagen Skin Booster Toner Serum is a lightweight, toner-textured essence formulated with six peptides including copper peptide (GHK-Cu) to help reinforce skin elasticity, refine texture, and prepare skin for the rest of your routine.

This product blends the convenience of a toner with the targeted benefits of a peptide serum. Designed to be applied immediately after cleansing, its thin, fast-absorbing texture primes skin to receive hydration and active treatments while delivering ingredients aimed at improving bounce, surface smoothness, and overall radiance. The formula emphasizes multiple peptides—among them copper peptide (GHK-Cu)—to support visible skin renewal without a heavy finish.

How should I use this toner-serum in my daily routine?

Apply the product right after cleansing, while skin is still slightly damp, to maximize absorption. Use 2–3 pumps and gently press or pat across face and neck, then follow with your moisturizer and targeted treatments.

• Apply 2–3 pumps to slightly damp skin after cleansing.
• Pat gently until absorbed; layer serums or essences afterward.
• Finish with moisturizer and sunscreen during daytime routines.

What do the peptides, including copper peptide, actually do for my skin?

The formula combines six peptides to support multiple visible concerns: elasticity, texture, and the appearance of fine lines. Copper peptide (GHK-Cu) is included as a supportive peptide that can assist skin renewal processes and help skin appear firmer when used consistently.

• Targets elasticity and firmness with a peptide blend.
• Helps improve perceived texture and pore appearance over time.
• Lightweight delivery allows layering with other actives.

Will this product work for oily, dry, or sensitive skin types?

The toner-serum’s thin, non-greasy feel suits a broad range of skin types. Its rapid absorption and minimal residue make it suitable for oily or combination skin, while the peptide complex can support dry or mature skin seeking improved bounce. Those with sensitive skin should patch-test first, as active peptides can sometimes cause reactivity for the most reactive individuals.

• Light texture fits oily and combination skin well.
• Peptide support benefits dry or mature skin needing elasticity.
• Patch-test if you have very reactive or sensitized skin.

How does this product pair with other COSRX favorites?

This booster works well as a base layer before richer essences or creams. It’s commonly paired with hydrating essences like COSRX Snail 96 or followed by targeted treatments such as COSRX Retinol 0.1 Cream for a layered routine that prioritizes renewal and hydration.

• Use before COSRX Snail 96 Essence to boost hydration layering.
• Apply prior to moisturizers or treatment creams like retinol.
• Compatible with most serums due to its toner-like consistency.

Who is this for: COSRX 6X Peptide Collagen Skin Booster Toner Serum is designed for people seeking a lightweight, multi-peptide essence that primes skin while addressing elasticity, texture, and the look of fine lines. It suits anyone who prefers a toner-step product that also delivers targeted peptide actives—especially those building a layered Korean-style routine. Avoid or patch-test if you are highly reactive to potent actives or new peptide blends.
