## Key ingredients

Octinoxate, Titanium Dioxide, Zinc Oxide, Patented Alguronic Acid, Echinacea Purpurea Extract

## 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](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- Application of Echinacea purpurea cream and gel increased skin hydration up to 10.6 AU and 11.4 AU and decreased wrinkles by 9.47% and 14.92% without causing skin irritation in 10 healthy volunteers over 1 month. ([International Journal of Cosmetic Science, 2010](https://pubmed.ncbi.nlm.nih.gov/20384903/))
- Biomimetic hyaluronic acid-stabilized zinc oxide nanoparticles selectively inhibited C. acnes, outperformed erythromycin in preclinical acne models, and safely reduced acne lesions and redness in a clinical trial. ([Journal of Controlled Release, 2025](https://pubmed.ncbi.nlm.nih.gov/40254135/))
- 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](https://pubmed.ncbi.nlm.nih.gov/29131088/))
- 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](https://pubmed.ncbi.nlm.nih.gov/24376350/))
- 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](https://pubmed.ncbi.nlm.nih.gov/21336009/))
- Microfine titanium dioxide does not penetrate human skin when formulated in an oil-in-water emulsion with the pigment dispersed in the aqueous phase, compared to oily dispersions and liposomal encapsulation which allow deeper skin penetration. ([International Journal of Cosmetic Science, 2000](https://pubmed.ncbi.nlm.nih.gov/18503414/))
- Replacing microsized titanium dioxide and zinc oxide with nanoparticles in sunscreens eliminates opaqueness and alters UV protection balance while inducing (photo)cyto- and genotoxicity and penetrating viable skin layers during long-term exposures. ([Nanotechnology, Science and Applications, 2011](https://pubmed.ncbi.nlm.nih.gov/24198489/))
- Microfine zinc oxide and titanium dioxide do not penetrate the stratum corneum of porcine skin in vitro, indicating that their use in sunscreens does not pose a health risk from internal exposure. ([Toxicology in Vitro, 2006](https://pubmed.ncbi.nlm.nih.gov/16182508/))
- Topical 0.5% hyaluronic-ZnO nanogel applied twice daily reduced inflammatory-lesion counts by 58% at week four in human subjects compared to baseline without causing erythema. ([Biomedicines, 2025](https://pubmed.ncbi.nlm.nih.gov/41007718/))
- Nels cream achieved a similar reduction in inflammatory and noninflammatory lesion counts compared to 5% benzoyl peroxide in acne vulgaris patients, but caused significantly fewer side-effects such as peeling and dryness. ([Clinical and Experimental Dermatology, 2000](https://pubmed.ncbi.nlm.nih.gov/10671963/))
- Topically applied coated and uncoated zinc oxide nanoparticles under flexing and massage are retained in the stratum corneum with no significant penetration into the viable epidermis and no cellular toxicity in human skin. ([Nanomedicine, 2016](https://pubmed.ncbi.nlm.nih.gov/27102240/))
- A new skincare formulation from Echinacea purpurea completely blocked the 40-60% reduction in skin nerve endings caused by UVA and UVB exposure in ex vivo human skin samples. ([Cell Proliferation, 2012](https://pubmed.ncbi.nlm.nih.gov/22151837/))
- Topical application of Echinacea pallida root extract and its constituent echinacoside showed good anti-inflammatory and wound healing properties compared to E. purpurea and control in rats. ([Journal of Ethnopharmacology, 2002](https://pubmed.ncbi.nlm.nih.gov/11801391/))
- A standardized preparation of Echinacea purpurea killed Propionibacterium acnes and completely reversed bacterial-induced pro-inflammatory cytokine secretion in cell culture models. ([Phytotherapy Research, 2011](https://pubmed.ncbi.nlm.nih.gov/20830697/))
