“…In addition, in vitro studies on cell cultures of normal human epidermal keratinocytes highlighted the protective effects of pomegranate fruit extract against UV-A and UV-B radiation [17,18]. The widespread cosmetic ingredient, shea butter (Butyrospermum parkii or Vitellaria paradoxa), has also been credited as being responsible for several effects after topical application, including photoprotective activity, but its real efficacy as a sunscreen agent has not yet been clearly demonstrated [19,20].…”

Some vegetable oils have many biological properties, including UV-absorbing capacity. Therefore, their use has been suggested to reduce the content of organic UV-filters in sunscreen products. In this work, we investigated the feasibility of developing oil-based vehicles with a high sun protection factor (SPF) using pomegranate oil (PMG) and shea oil (BPO) in association with different percentages of organic UV-filters (octyl– methoxycinnamate, butyl methoxydibenzoylmethane, and bemotrizinol). We characterized the spreadability, occlusion factor, pH, and required hydrophilic lipophilic balance of the resulting formulations, and did not observe relevant differences due to the incorporation of vegetable oils. The in vitro spectrophotometric determinations of SPF values highlighted that the addition of BPO (1% (w/w)) and PMG (1% (w/w)) resulted in an increase in SPF in comparison with the same formulations that contained only organic UV-filters. The SPF increase was more significant for the formulations that contained lower amounts of organic UV-filters. The results of this study supported the hypothesis that including suitable vegetable oils in sunscreen formulations could be a promising strategy to design products with a lower content of organic UV-filters.

“…It is a waxy material extracted from the nut of Vitellaria paradoxa tree and acts as a skin, scalp and hair emollient and moisturizer. [8][9][10] It melts at body temperature, has good water-binding properties, and acts as a "refatting" agent. 11 Also, it has been shown to effectively prevent transepidermal water loss (TEWL).…”

Background Ultraviolet (UV) radiation exposure is related to skin and lip tumors. Therefore, the development of photoprotective lipstick formulations is of utmost importance. Aims Considering the biological properties of Shea butter (Butyrospermum parkii), we assessed its potential as an adjuvant in a molded lipstick sunscreen system by in vivo tests and photostability. Patients/Methods Shea butter was used in a photoprotective lipstick formulation at two different concentrations (10.0% and 15.0% w/w) associated with ethylhexyl methoxycinnamate (EHM) and titanium dioxide. Skin compatibility was assessed in vivo. The in vivo SPF value was determined according to the current recognized method. Additionally, the photostability of EHM was determined by high‐performance liquid chromatography. Results By the cutaneous compatibility, the product presented no interference with skin barrier and no adverse reactions, thus proving its safety. The in vivo SPF assay showed that the highest concentration of Shea butter increased the in vivo SPF value of the sample by 35%, demonstrating it to be a booster in photoprotective lipstick formulations. Also, Shea butter was proved to enhance the photostability of EHM, a commonly used UVB filter available in several countries. Conclusion Shea butter increased the photostability and in vivo SPF of a molded lipstick sunscreen.

“…Activation of PPARγ stimulates epidermal lipid production and differentiation, both of which benefit epidermal permeability barrier [ 46 ]. The content of linoleic acid in cocos nucifera oil and butyrospermum parkii, sources of linoleic acid in Physiogel Intensive Cream, ranges 3–11% [ 47 , 48 ] while olea europaea (Olive) fruit oil and vitis vinifera seed oil, ingredients in Atopalm MLE Cream, are enriched in linoleic acid (as high as over 70%) [ 49 ]. Third, both antioxidant (tocopheryl acetate) and hyaluronate, ingredients in Atopalm MLE Cream, benefit the epidermal permeability barrier [ 50 – 52 ].…”

IntroductionThe management of sensitive skin, which affects over 60% of the general population, has been a long-standing challenge for both patients and clinicians. Because defective epidermal permeability barrier is one of the clinical features of sensitive skin, barrier-enhancing products could be an optimal regimen for sensitive skin. In the present study, we evaluated the efficacy and safety of two barrier-enhancing products, i.e., Atopalm® Multi-Lamellar Emulsion (MLE) Cream and Physiogel® Intensive Cream for sensitive skin.Methods60 patients with sensitive skin, aged 22–40 years old, were randomly assigned to one group treated with Atopalm MLE Cream, and another group treated with Physiogel Intensive Cream twice daily for 4 weeks. Lactic acid stinging test scores (LASTS), stratum hydration (SC) and transepidermal water loss (TEWL) were assessed before, 2 and 4 weeks after the treatment.ResultsAtopalm MLE Cream significantly lowered TEWL after 2 and 4 weeks of treatment (p < 0.01). In contrast, Physiogel Intensive Cream significantly increased TEWL after 2 weeks of treatment (p < 0.05) while TEWL significantly decreased after 4-week treatments. Moreover, both Atopalm MLE Cream and Physiogel Intensive Cream significantly increased SC hydration, and improved LASTS after 4 weeks of treatment.ConclusionBoth barrier-enhancing products are effective and safe for improving epidermal functions, including permeability barrier, SC hydration and LASTS, in sensitive skin. These products could be a valuable alternative for management of sensitive skin.FundingVeterans Affairs Medical Center, San Francisco, California, USA, and NeoPharm Co., Ltd., Daejeon, Korea.Electronic supplementary materialThe online version of this article (doi:10.1007/s13555-016-0097-6) contains supplementary material, which is available to authorized users.
