What is the least irritating preservative?

by | Jul 31, 2026

🗳️ From The Question Box: “Hey Marie! Asking with the disclaimer ‘I know we are not dermatologist and our skin care products are not allowed to say they treat dermatological conditions”‘ … I was recently given a diagnosis of Rosacea and a long list of “Rosacea friendly” products by my Derm, 90% of which are not, in fact Rosacea friendly due to the addition of about 100 different ingredients that are known irritants. Yikes. My question is, is there a known LEAST irritating preservative out there we can use when making/formulating our own skin care and/or of the ones you have used what is the most gentle/non-irritating. ” – JenCamp
