  intro: "Texture is a patience question. Most of what feels like texture resolves with the routine you already have, given six weeks. The mistake most people make is reaching for stronger actives when the problem is actually inconsistency: not exfoliating regularly enough, using products that don't fully absorb, or alternating between too many things to tell what's working. Real surface texture — bumps that don't have a head, milia that sit hard beneath the skin, rough patches that persist regardless of hydration — responds to gentle, regular chemical exfoliation and not much else. Below is the full library: what different textures actually are, which approach fits which situation, and why leaving well enough alone is sometimes the best move.",

    body: "Surface texture describes anything that makes skin feel or look uneven under light: rough patches, bumps without a head, milia, and general roughness that makes makeup sit unevenly. It's distinct from congestion (which involves clogged pores) and from acne (which involves infection). Texture is a surface condition, usually driven by accumulated dead cells, thickened sebum, or small keratin deposits. Most of it is manageable with consistent, gentle chemical exfoliation.",
