A Korean EGF pore ampoule developed in collaboration with 4ever Dermatology Clinic — one of South Korea's leading skincare clinics. Built on 74% botanical extract base (chamomile + honeysuckle flower water instead of plain water) and powered by 10GF, Kopher's proprietary complex of 10 growth factor types including EGF. Clinical results: 10.59% improvement in horizontal pore size and 10.09% in vertical pore size after just 2 weeks. Fragrance-free, color-free, non-comedogenic, weakly acidic pH. Suitable for sensitive and acne-prone skin. 50ml.

• 10GF — Ten Types of EGF (Epidermal Growth Factor) — EGF was first discovered by Dr. Stanley Cohen in 1986, earning him the Nobel Prize in Physiology; EGF are signal molecules that stimulate cell growth, barrier repair and skin renewal; Kopher's 10GF complex uses 10 different growth factor variants including sh-oligopeptide-2 and sh-polypeptide-1 to comprehensively target barrier weakness, fine lines and sagging at the cellular level. Note: avoid if you have psoriasis or are at elevated risk of skin cancer
• Pore-Biome Complex (Exclusive to Signature Ampoule) — Kopher's proprietary complex found only in this product; targets both wide pores and fine pores simultaneously by improving dual elasticity — the horizontal and vertical dimensions of pore walls that determine visible pore size; clinically proven 10.59% horizontal + 10.09% vertical improvement in 2 weeks
• 74% Botanical Extract Base — chamomile flower extract and honeysuckle flower extract replace plain water as the formula base; at 74% this is a meaningful concentration of natural soothing and barrier-supporting extracts that keep the formula gentle enough for sensitive and acne-prone skin throughout daily use
• Triple Hyaluronic Acid + Ceramide NP + Niacinamide — hydration, barrier and brightening support trio; triple HA hydrates at multiple skin depths; ceramide NP rebuilds the lipid barrier; niacinamide evens tone, minimizes pore appearance and controls sebum — working alongside the Pore-Biome complex for comprehensive pore care
• Weakly Acidic pH Formula — formulated at a slightly acidic pH close to the skin's natural acid mantle; this maintains optimal barrier function and ensures the growth factors and other actives can absorb and function effectively without disrupting skin balance

After cleansing, pump 2–3 times and apply at the essence step. Roll gently as if massaging, then pat to absorb. For pore-focused care, layer once more on areas where pores are most visible. 50ml.
