Rich in exopolysaccharides, phycoerythrin pigments, polyunsaturated fatty acids, and a broad spectrum of antioxidants, it delivers comprehensive protective, regenerative, and barrier-strengthening benefits to the skin.","detailed_content":"Porphyridium Cruentum belongs to the class Rhodophyta \u2014 the red algae \u2014 and is distinguished from macroscopic seaweeds by its unicellular structure and the remarkable biochemical complexity of the compounds it produces. Living at depth in nutrient-rich marine environments, this microalga is exposed to high levels of UV radiation, oxidative stress, and temperature extremes. Over evolutionary time, it has developed a sophisticated suite of protective mechanisms \u2014 including the production of sulfated exopolysaccharides, phycoerythrin proteins, and a diverse array of antioxidant pigments \u2014 that allow it to thrive under conditions that would be lethal to most organisms. These same compounds, when extracted and applied to human skin, deliver a comparable protective effect.\r\n\r\nThe exopolysaccharide fraction of Porphyridium Cruentum is of particular interest in cosmetic science. These sulfated polysaccharides form a viscous, gel-like matrix around the algal cell, protecting it from desiccation, UV damage, and pathogen attack. When incorporated into skincare formulations, they contribute to the formation of a flexible, moisture-retaining film on the skin surface \u2014 one that improves skin feel, reduces transepidermal water loss, and provides a physical barrier against environmental aggressors. In combination with Pullulan and HPMC in the Instant D Day Cream, this film-forming property contributes to the product's signature immediate tightening and smoothing effect.\r\n\r\nBeyond its physical properties, Porphyridium Cruentum Extract is an exceptionally rich source of bioactive lipids, essential and non-essential amino acids, vitamins, and minerals \u2014 providing a comprehensive nutritional substrate for skin cell function. Its antioxidant capacity is particularly relevant in the context of the Instant D Day Cream, where it works synergistically with NECTARIA LITHOPS and Vitamin E to protect the skin's cellular microenvironment and optimise the conditions necessary for efficient Vitamin D synthesis \u2014 the central mechanism of action of this unique daily care formulation.","pdf_link":"","product_link":"","pdf_image_p1":"","pdf_image_p2":"","pdf_image_p3":"","pdf_image_p4":"","pdf_image_p5":"","pdf_image_p6":"","sources":""},"_links":{"self":[{"href":"https:\/\/forget-about-age.com\/fr\/wp-json\/wp\/v2\/ingredient\/14777","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/forget-about-age.com\/fr\/wp-json\/wp\/v2\/ingredient"}],"about":[{"href":"https:\/\/forget-about-age.com\/fr\/wp-json\/wp\/v2\/types\/ingredient"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/forget-about-age.com\/fr\/wp-json\/wp\/v2\/media\/14845"}],"wp:attachment":[{"href":"https:\/\/forget-about-age.com\/fr\/wp-json\/wp\/v2\/media?parent=14777"}],"wp:term":[{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/forget-about-age.com\/fr\/wp-json\/wp\/v2\/product_tag?post=14777"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
