Zuofun’s skincare manufacturing runs on an in-house library of over 8,000 mature formulas across face, body, eye and lip categories, produced from our Guangzhou facility under audited GMP production. We support both fast-turn private-label orders from an existing formula and fully custom actives-forward development — retinol, vitamin C, niacinamide, peptides — with stability testing behind every shelf-life claim. See our guide to private-label skincare manufacturing for MOQ, compliance and formulation details.
