Deoxyribonuclease

Deoxyribonuclease (DNase) is an enzyme that breaks down DNA. In skincare, it functions as a skin conditioning agent, working to support the skin's natural maintenance and repair mechanisms.The enzyme has been studied primarily in the context of wound healing, particularly where inflammation and immune cell activity need to be modulated. Its inclusion in topical formulations is based on research into how it may help manage the aftermath of inflammatory processes on the skin.

During inflammation or wound healing, immune cells release DNA into the surrounding tissue. Deoxyribonuclease works by enzymatically breaking down this extracellular DNA, which can otherwise accumulate and prolong inflammatory signals. By clearing this material, the enzyme may help transition the skin from an inflammatory state to a repair state more efficiently.This mechanism is particularly relevant in scenarios where the skin's immune response has been overactive, as sustained inflammation can impair healing and contribute to skin damage.

Deoxyribonuclease is typically incorporated into serums, treatments, or hydrogel formulations designed to support skin repair and calm inflammation. If using a product containing this ingredient, apply as directed and allow adequate time for the skin to respond. It may be most beneficial during or after periods of heightened skin sensitivity or irritation, though it can form part of regular skincare routines for those seeking to optimise inflammatory responses.

Deoxyribonuclease is generally well-tolerated as a topical ingredient. No significant adverse effects have been reported in skincare applications, though patch testing is sensible for those with known enzyme sensitivities.
