Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

If derived from marine or animal sources, those with related sensitivities should use caution; no widely noted regulatory limits apply in typical cosmetic use.

Is Soluble Proteoglycan a Good Ingredient?

It rates Fair because it acts as a water-binding macromolecule that improves short-term hydration, but strong independent clinical support is limited. As a biologically sourced protein-polysaccharide, it may also pose a mild irritation or sensitization risk for some users.
