Science & Benefits

Dimethyl Isosorbide is a sustainable, high-purity solvent that functions as a penetration enhancer. It works by creating a 'reservoir' of active ingredients in the stratum corneum, allowing for a sustained release into the deeper layers of the epidermis. It is zero-comedogenic and zero-irritant. For acne patients, DMI is critical because it enables water-soluble actives (like Salicylic Acid or Azelaic Acid) to bypass the skin's oily surface barrier without requiring skin-stripping alcohols.
