The Ordinary Balancing & Clarifying Serum is a water-based multi-active serum formulated to address signs of congestion, excess oil and the appearance of enlarged pores. Key actives include sarcosine and L‑carnitine, which target surface oiliness and visible shine; polylysine, a patented branched amino-acid polymer that also helps reduce oiliness; and N‑acetylglucosamine, an amino sugar with exfoliation-like effects that supports smoother, more even texture. Ectoin and lactococcus ferment lysate support the skin barrier and help retain hydration, while adenosine contributes to improved pore appearance. Other formulation components include potassium azeloyl diglycinate, glycerin and silanetriol. Usage: shake before use and apply a few drops to clean skin in the morning and evening; patch testing is advised and discontinue if irritation occurs. Benefits reported on brand and retailer listings include reduced shine, improved skin texture, clearer-looking skin and reduced appearance of post‑acne marks. Although especially suited to oily and combination skin, the formulation is tested and listed as suitable for all skin types. No size or set contents are specified here.
