Lessonia

 

a genus of brown algae of the order Laminariales. There are five species, distributed primarily in the cold and temperate seas of the southern hemisphere, where they form true underwater forests. In the northern hemisphere there is one known species, which is found in the Sea of Okhotsk. The thallus reaches a length of 4 m and is branched, with rhizoids at the base and plates at the ends of the branches.

* Easy Way is a new, well-calibrated fine powder for skin cream and serums that is said to stimulate the skin renewal process with an easy mechanobiology gesture, according to Lessonia. After several years of research with an academic French R&D center, scientists demonstrated that after mechanical stimulation by small and well calibrated particles on the HIPPO signaling pathway, the transcriptional co-activators YAP and TAZ migrate from the cytoplasm to the nucleus.

chocolata is distributed over a rocky substrate, associated in the shallow areas with banks of the mytilidae Chorumytilus chorus (Molina, 1782), and the brown algae Lessonia trabeculata (Villouta & Santelices, 1986), and in the deep area, with banks of the mytilidae Aulacomya ater (Molina, 1782) which extends over 30 m depth.
Mazzaella laminarioides (Bory de Saint-Vincent) Fredericq, Ulva compressa Linnaeus and Lessonia spicata (Suhr) Santelices] are more sensitive to desiccation, and this seems related to the absence of efficient mechanisms to attenuate the over-production of ROS during rehydration (Contreras-Porcia et al., 2012; Lopez-Cristoffanini et al., 2013).
