Science
Mechanism of Action
DNase functions as an endonuclease, precisely cleaving the phosphodiester backbone of DNA into oligonucleotide fragments. This enzymatic activity is vital for disassembling ecDNA, which is released during cellular processes like apoptosis, necrosis, and neutrophil extracellular trap formation, thereby mitigating inflammatory responses. Specifically, DNase I primarily targets double-stranded DNA. Skin-specific isoforms like DNase II α and DNase1L2 are integral to maintaining skin cell homeostasis; DNase II α supports the skin's barrier integrity against microbial threats, while DNase1L2 is active in degrading bacterial biofilms for pathogen protection.

The Formula
Formulation
Stability
DNase I exhibits stability in aqueous solutions within a pH range of 5.0 to 7.0 and at temperatures up to 60 °C for durations of at least five hours. For enhanced stability during storage, it is recommended to maintain a minimum concentration of 1 mg/ml in a 50% glycerol solution. Significant activity loss occurs with heat exposure; complete inactivation is observed after 10 minutes at 75°C, and activity diminishes in less than 10 minutes at 68°C.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet reviewed Deoxyribonuclease. However, the Environmental Working Group (EWG) assigns a 'LOW' concern rating for potential cancer, allergies/immunotoxicity, and developmental/reproductive toxicity risks. The European Chemicals Agency (ECHA) has reported limited evidence of dermal toxicity or allergic reactions. It is important to note that while cosmetics do not require FDA approval prior to marketing, the FDA monitors products making drug claims. No specific FDA approval status or maximum concentration guidelines for cosmetic use were identified.
