## What the research says

- 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/))
- 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/))
- 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/))

Sources: [Archives of Dermatological Research, 2024](https://pubmed.ncbi.nlm.nih.gov/39499337/), [International Journal of Nanomedicine, 2013](https://pubmed.ncbi.nlm.nih.gov/24376350/)

### What does Titanium Dioxide do for oily skin?

Titanium dioxide acts as a physical UV filter that sits on the outermost surface of the skin without clogging pores or making oily skin feel greasy. When used in sunscreens, this ingredient helps protect your face from sun damage while having a very safe profile on healthy skin.
Sources: [Skin Pharmacology and Applied Skin Physiology, 2001](https://pubmed.ncbi.nlm.nih.gov/11509913/), [Journal of the European Academy of Dermatology and Venereology, 2019](https://pubmed.ncbi.nlm.nih.gov/31588611/)

### Can I use this fluid with retinol, and in what order?

You can use this fluid in the morning as the final step of your routine, after your moisturizer and before any makeup. It is safe to use alongside retinol applied at night, as this fluid provides strong UV protection without harsh ingredients that could irritate your skin.

### How often should I use this fluid?

You can use this fluid every morning as the final step of your daytime routine to defend against the sun while keeping your skin feeling light and shine-free. It has an excellent safety profile with very low likelihood of irritation.
Sources: [Cell Proliferation, 2012](https://pubmed.ncbi.nlm.nih.gov/22151837/), [Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36607762/)

Algenist Sublime Defense Ultra Lightweight UV Defense Fluid SPF 50 is unlikely to clog pores or cause breakouts for oily skin, thanks to its very safe makeup and lightweight feel. It does not contain harsh ingredients that typically trigger irritation, and it helps control oil to keep your skin comfortable.

### Is this fluid fragrance-free and alcohol-free?

It contains fragrance (parfum, hexyl cinnamal, and linalool) and drying alcohol (alcohol denat).
