The medicube Zero Pore One Day 10 Peptide Serum is a daily pore-focused care product formulated for those seeking to refine pore appearance and balance oil production. This 1.01 fl oz serum combines a multi-acid complex of AHA, BHA, PHA, and LHA with copper peptide GHK-Cu, offering a dual approach to exfoliation and skin firming. The acids work to gently dissolve excess sebum and dead skin cells, helping to clear clogged pores and smooth skin texture over time. The inclusion of copper peptide, known for its role in supporting collagen synthesis, aims to promote firmer, more resilient skin. Designed for regular use, the serum targets enlarged pores and uneven texture without aggressive irritation, making it suitable for individuals with oily or combination skin types. Its lightweight, non-greasy texture absorbs quickly and layers well under moisturizer or sunscreen. As a Korean skincare product, it emphasizes gentle yet effective ingredient layering. The serum does not contain synthetic fragrances or dyes, and is free from parabens and sulfates. Routine application—typically after cleansing and before moisturizing—helps maintain a clearer, more refined complexion. Users with sensitive skin should patch test due to the presence of multiple acids. The product is intended to complement a broader skincare regimen focused on pore management and oil control. No instant or absolute results are claimed; individual outcomes vary based on skin condition and consistency of use. The formulation prioritizes gradual improvement through mild chemical exfoliation and peptide-supported firmness, without relying on harsh physical abrasives.
