Questions and answers

What the research says

• A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.

  Clinical, Cosmetic and Investigational Dermatology, 2017

• Topical formulations based on starches with and without Spirulina maxima extract demonstrated film-forming effects on the skin and hair, reducing transepidermal water loss and improving hair tensile properties.

  AAPS PharmSciTech, 2022

• Supplementation of a broad-spectrum sunscreen with Spirulina and dimethylmethoxy chromanol significantly improved skin pigmentation, reduced collagen degradation, and enhanced net elasticity in 44 healthy subjects after 84 days compared to sunscreen alone.

  European Journal of Pharmaceutical Sciences, 2017

• Spirulina, Palmaria palmata, Cichorium intybus, and Medicago sativa extracts alone or combined present no in vitro toxicity or irritant potential, and provoke no skin barrier alteration or irritation in twenty human subjects.

  Cutaneous and Ocular Toxicology, 2019

• The Spirulina subsalsa starch fraction SPS-1 exhibited anti-photoaging effects in UVB-irradiated HaCaT cells and enhanced skin barrier function in vivo by attenuating oxidative stress, suppressing inflammation, and restoring extracellular matrix homeostasis.

  Carbohydrate Polymers, 2026

• Encapsulation of ethylhexyl methoxycinnamate and butyl methoxydibenzoylmethane in lipid microparticles significantly reduced their in vivo human skin penetration compared to nonencapsulated filters.

  Skin Pharmacology and Physiology, 2011

• Microencapsulation of the BMDBM/HP-beta-CD complex in lipid microparticles significantly decreased the percutaneous penetration of the UV filter into the stratum corneum of human volunteers compared to the non-encapsulated sunscreen agent.

  Journal of Pharmaceutical and Biomedical Analysis, 2011

• Following human skin application of an O/W emulsion containing 2% BMDBM loaded in lipospheres, 15% of the sunscreen accumulated in the uppermost layers of the stratum corneum without remarkably modifying skin permeation compared to unencapsulated sunscreen.

  Skin Pharmacology and Physiology, 2008

• Replacing 20% of the chemical UV filter octyl methoxycinnamate with urucum oil in solid lipid nanoparticles maintained the skin protection factor without inducing toxic responses or significant skin penetration in human volunteers.

  Skin Pharmacology and Physiology, 2018

• Liposomal encapsulation of octyl methoxycinnamate increases its safety, skin affinity, and in vivo solar photoprotection factor while slowing its release and enhancing retention in the stratum corneum compared to a conventional formulation.

  International Journal of Nanomedicine, 2013

• The application of a sunscreen formulation containing ethylhexyl methoxycinnamate, ethylhexyl salicylate, methyl anthranilate, and octocrylene does not significantly affect critical acne-related species such as Cutibacterium acnes and Staphylococcus epidermidis, refuting the induction of facial dysbiosis in men.

  Archives of Dermatological Research, 2024

• Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control.

  Journal of Drugs in Dermatology, 2011

• Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.

  Clinical Oral Investigations, 2022

• Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days.
