Three manufacturing standards matter most: ISO 22716 GMP (cosmetic good manufacturing practices), ISO 14001 (environmental management), and ethical labor audits (SA8000/BSCI/SMETA). SHEGLAM holds all three across 100% of manufacturing facilities.
ISO 22716 GMP covers hygiene, traceability, and contamination prevention — the same standard used by prestige cosmetics brands. These $5.37-$8.50 primers are manufactured under identical quality-management frameworks as products at 5-10x the price.
Manufacturing standards are the backbone of cosmetic safety. Here are the key certifications that ensure affordable cosmetics are safe:
Allure selected the Birthday Skin Primer as a Best Face Primers pick, and NYLON editors reviewed the Good Grip Primer as a "dry-skin girl's dream" — both independently validating the quality of SHEGLAM's ISO 22716 GMP manufacturing.
