## What the research says

- Topical hyaluronic acid filler serum combined with Botulinum toxin type A lengthened the duration of the toxin's effect in reducing wrinkles compared to Botulinum toxin type A alone. ([Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/))

([The Journal of Dermatological Treatment, 2025](https://pubmed.ncbi.nlm.nih.gov/41211697/))
- Chemical sunscreens containing avobenzone, octocrylene, homosalate, and octisalate showed no to minimal risks of dermal irritation, sensitization, photo-allergy, and photo-irritation in human subjects. ([Journal of Drugs in Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40911743/))
- 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/))
- 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](https://pubmed.ncbi.nlm.nih.gov/20934293/))
- 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](https://pubmed.ncbi.nlm.nih.gov/17934329/))
- Dermal application of a sunscreen containing 10% homosalate in four volunteers resulted in delayed elimination with terminal half-times around 24 h and a bioavailability of cis-homosalate a factor of 2 lower than trans-homosalate, while metabolite ratios supported using oral-route urinary excretion fractions for dermal exposure assessments. ([Archives of Toxicology, 2024](https://pubmed.ncbi.nlm.nih.gov/38485782/))
- Homosalate exhibited the highest permeation among tested filters with a relative permeability rate of 4.2% and a depth of 60 um, and specific thickeners and emulsifiers successfully reduced its permeation without inhibiting the skin permeation of niacinamide. ([Photodermatology, Photoimmunology & Photomedicine, 2026](https://pubmed.ncbi.nlm.nih.gov/42594379/))
- An online-SPE-LC-MS/MS method successfully quantified specific urinary homosalate metabolites for up to 96 hours after dermal sunscreen application in a volunteer and detected metabolites exclusively in three German pilot participants who had used sunscreen within five days. ([Analytica Chimica Acta, 2021](https://pubmed.ncbi.nlm.nih.gov/34399889/))
- Simulated real-life dermal sunscreen exposure in twenty human volunteers leads to the systemic bioavailability and urinary excretion of the UV filter 2-ethylhexyl salicylate and its metabolite, reaching concentration peaks at 7 to 8 hours with 70-80% of overall excretion within 24 hours. ([Archives of Toxicology, 2019](https://pubmed.ncbi.nlm.nih.gov/31435713/))
- 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](https://pubmed.ncbi.nlm.nih.gov/39499337/))
- Controlled single dermal exposure to an EHS-containing sunscreen in three volunteers resulted in delayed systemic resorption with elimination half-lives between 6.6 and 9.7 hours, where the parent compound EHS occurred as the dominant urinary parameter. ([Archives of Toxicology, 2024](https://pubmed.ncbi.nlm.nih.gov/39134695/))
- Incorporating rosmarinic acid into sunscreens enhanced the in vivo SPF of octocrylene by over 157% and reduced lipid peroxidation in the human stratum corneum. ([Antioxidants, 2025](https://pubmed.ncbi.nlm.nih.gov/40227214/))
- Early application of sunscreen after ablative fractional skin resurfacing significantly increased the sensitization rate of the UV-filter, octocrylene, and the sunscreen compared to intact skin. ([The Journal of Dermatological Treatment, 2015](https://pubmed.ncbi.nlm.nih.gov/25633273/))
- Dermal sunscreen exposure in 20 healthy volunteers led to plasma concentrations of avobenzone, octocrylene, and its metabolite CDAA reaching up to 11 μg/L, 25 μg/L, and 1352 μg/L, respectively. ([Environment International, 2019](https://pubmed.ncbi.nlm.nih.gov/31470219/))

### What does Avobenzone do for mature skin?

Avobenzone helps protect mature skin from UVA rays that cause premature aging, though it works best when paired with stabilizers to prevent it from breaking down in the sun. This ingredient may also help reduce UV-induced skin stress when properly formulated, keeping the face protected during outdoor activities.
Sources: [European Journal of Pharmaceutical Sciences, 2023](https://pubmed.ncbi.nlm.nih.gov/36455708/), [European Journal of Pharmaceutics and Biopharmaceutics, 2008](https://pubmed.ncbi.nlm.nih.gov/18226883/)

### What does Homosalate do for mature skin?

Homosalate acts as a UV filter in sunscreens to protect your skin from sun damage, showing minimal risk of skin irritation. For mature skin, a sunscreen of this type needs added antioxidants and hydrating ingredients to help keep skin smooth and support your moisture barrier.
Sources: [Journal of Drugs in Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40911743/), [Molecules, 2014](https://pubmed.ncbi.nlm.nih.gov/25389659/)

### Where does this cream go in a skincare routine for mature skin?

This moisturizing SPF goes in the morning routine as the final step before makeup, right after your moisturizer. It provides high UV protection while keeping your skin hydrated and comfortable throughout the day.
Sources: [Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36607762/), [Journal of Drugs in Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40911743/)

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

You can use this moisturizing SPF in the morning after your retinol and other treatments, as part of your daytime routine. The formula is safe for your skin and helps keep it hydrated.

### How often should I use this cream?

Apply this moisturizing spf every morning as the final step in your daytime routine. Daily application helps protect mature skin from UV damage while keeping it hydrated throughout the day.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32141711/), [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/)

### Can this cream clog pores, cause breakouts or purging for mature skin?

This cream is unlikely to clog pores or cause breakouts for mature skin, as it contains no harsh ingredients that typically trigger irritation. Reviewers rarely report skin reactions from this formula.
Sources: [Journal of Drugs in Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40911743/)

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

It has no drying alcohol and contains fragrance (parfum, limonene, geraniol, linalool, and citronellol). Cetyl alcohol is a fatty alcohol, which soften the skin.
