Clinical Efficacy of Dermocosmetic Formulations Containing Spirulina Extract on Young and Mature Skin: Effects on the Skin Hydrolipidic Barrier and Structural Properties

Abstract

Introduction: Spirulina is a unicellular blue-green alga rich in vitamins, minerals, pigments, proteins, polysaccharides, which indicates a high potential use in anti-aging cosmetic products as well as for skin protection. Preliminary studies showed antioxidant potential, immediate benefits on the skin microrelief and hydration and skin compatibility of formulations containing Spirulina extract. Thus, the objective of this study is to evaluate the long term clinical efficacy of dermocosmetic formulations containing Spirulina extract on young and mature skin using biophysical and skin imaging techniques.

Radical-Scavenging Activity of a Sunscreen Enriched by Antioxidants Providing Protection in the Whole Solar Spectral Range

“…These 4 molecules were evaluated because they are present in most commercial products in the market, and when formulated in combination provide protection from UVB and UVA radiation. Spirulina is a green microalga obtained by a biotechnological process that presents a rich composition of provitamin A, vitamin B, proteins, and polysaccharides, with great AO activity and that may also assist in maintaining skin eudermia [17,18,19]. DMC is a synthetic analog of γ-tocopherol, capable of neutralizing both ROS and RNS, which is a great advantage compared to the other known AO that are capable to react with only 1 of those species.…”

Development of Spray Dried Spirulina Protein-Berry Pomace Polyphenol Particles to Attenuate Pollution-Induced Skin Damage: A Convergent Food-Beauty Approach

“…Spirulina has also been explored for personal care and pharmaceutical uses such as cosmetics and skin health applications [17,18]. Topical applications developed with Spirulina extracts have efficiently improved epidermis structure [19], promoted faster wound healing and enhanced collagen production [20]. In tandem, there is solid evidence regarding the health protective effects of naturally occurring fruit-derived polyphenols [21][22][23].…”

Desenvolvimento e eficácia clínica de formulações dermocosméticas para o controle de alterações cutâneas relacionadas ao fotoenvelhecimento

“…Com isso, ela é indicada para uso tópico noturno. Possui aplicação em medicina para combater as deficiências nutricionais em países subdesenvolvidos (Soni;Sudhakar;Rana, 2017) e em cosméticos como um ingrediente ativo multifuncional (Delsin et al, 2015;Melo et al, 2021). A sua utilização em cosméticos é patenteada pelo grupo de pesquisa, como antioxidante para prevenir os radicais livres que agem no fotoenvelhecimento, por suas propriedades de hidratação e melhora da aparência geral da pele Corauce, 2012).…”
