Science
Mechanism of Action
This extract is believed to provide comprehensive UV-protection by functioning throughout the dermis and epidermis, potentially offering deeper protection than traditional UV filters. Its mechanism involves reducing the formation of reactive oxygen species (ROS) induced by UV light. Furthermore, the extract is rich in naturally produced UV-absorbing compounds such as carotenoids, shinorine, and mycosporine-glycine (MAAs), synthesized in response to UV-B and UV-A exposure. It is also thought to ameliorate the immunosuppressive effects of UV radiation by inhibiting immune system impairment and promotes the accumulation of proline, a known stress-mitigating compound.

Stability
No specific optimal pH range for stability in cosmetic formulations has been identified. For laboratory pigment extraction, cells were resuspended in 50 mM Tris-HCl buffer at pH 7.5.
Safety
Safety Profile
No formal safety assessments by CIR, SCCS, or FDA are available for this ingredient as a cosmetic additive. However, a specific strain, Chlorogloeopsis fritschii PCC 6912, was analyzed and found free of cylindrospermopsins, microcystins, and anatoxins.
