Micrococcus Lysate is an extract derived from the bacterium Micrococcus luteus, containing enzymes (such as DNA photolyase and endonucleases) used in topical formulations to support cellular DNA repair following UV exposure and to provide antioxidant protection. It is typically incorporated into liposomal delivery systems in anti-aging and after-sun products.
| Reported effect | How often | Notes |
|---|---|---|
Mild localized irritation or stinging | Rare | Transient and usually related to the overall formulation rather than the lysate itself. |
Contact dermatitis / allergic sensitization | Very rare | Possible due to its protein/enzyme content, as with other biologically derived ingredients. |
Redness or erythema | Rare | Generally mild and self-resolving. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
