Cosrx The 6 Peptide Skin Booster Serum 150ml

Deliver a concentrated dose of six targeted peptides directly to freshly cleansed skin with this 150 ml facial booster serum that reinforces collagen synthesis while smoothing surface texture.

Targeted Structural and Tone Correction

Situated functionally between a clarifying toner and a hydrating essence, this lightweight fluid relies on a specifically proportioned peptide matrix to stimulate structural protein production in the deeper skin layers. Consistent application yields a visibly lifted contour and tighter pore boundaries, while simultaneously managing excess sebum to maintain a clear, reflective complexion without stripping barrier lipids.

Routine Layering Compatibility

Because the base absorbs rapidly without leaving a viscous film, you can follow directly with active treatments like vitamin C derivatives, niacinamide, hyaluronic acid, or retinol formulations without pilling or diluting their concentration. The formula acts as a dedicated preparation step, priming the stratum corneum so subsequent emollients and occlusive creams adhere uniformly and penetrate more efficiently.

Daily Application Protocol

Apply the serum as your very first treatment immediately after cleansing. Dispense 2–3 pumps, distribute evenly across the face and neck, and press gently until fully absorbed before introducing essences, spot treatments, or moisturizers. The standard 150 ml reservoir supports uninterrupted twice‑daily protocols, eliminating the need for frequent repurchasing while maintaining consistent peptide exposure.
