The Biology of the Compromised Acid Mantle
Healthy skin operates between pH 4.7 and 5.5, bathed in antimicrobial peptides and a dense lipid mortar. When alkaline foaming cleansers or direct acids strip this shield, the skin enters a state of chronic sub-clinical inflammation.
Eliminate Foaming Cleansers
Surfactants with strong ionic charges (SLS, high-pH soap bars) denature stratum corneum keratin proteins, swelling corneocytes and dislodging intercellular lipids.
Enforce Zero-Therapy for Rebounds
Perioral dermatitis is primarily an over-moisturization and topical steroid rebound disease. Complete cessation of cosmetics allows the native lipid matrix to reset.
Starve Malassezia Yeasts
Fungal acne feeds directly on carbon chain lengths C11 through C24. Replacing plant seed oils with bio-inert squalane or MCT prevents yeast proliferation.
