POLYGLYCERYL-4 ISOSTEARATE
Is POLYGLYCERYL-4 ISOSTEARATE safe for seborrheic dermatitis?
Polyglyceryl-4 Isostearate is context-dependent for seborrheic dermatitis. It supports emulsions, and the cosmetic safety conclusion for this ingredient family depends on a non-irritating formulation.
A laboratory study of sunscreen emulsions used it with several other ingredients and cannot establish an isolated seb derm effect. No applicable human seb derm or exact-ingredient Malassezia study was found. Ingredient names do not predict the behaviour of an entire emulsion; consider the complete product and avoid cosmetics that repeatedly cause discomfort.
