Hypoallergenic

"Hypoallergenic" is not a regulated term in the U.S., so most brands use it loosely. PopsyKosy backs the claim with a third-party Repeat Insult Patch Test (RIPT) — a 21-day exposure study on volunteer subjects under occlusive patches. No erythema, edema, or sensitisation responses observed.

This matters for the ~20% of children with sensitive skin, eczema, or contact dermatitis tendencies.
