Spot-lightening Treatments

Facial pigmentation increases with age and sun exposure, and represents an aesthetic problem for many. Multiple strategies are required for the cosmetic treatment of such imperfections, including accelerating skin renewal, inhibiting free radicals, providing photoprotection, prohibiting melanin granule formation and transfer, reducing pigmentation with sequestering agents, and enhancing skin penetration. These are described here.

Smart Lipid-carotene System for Targeted Free Radical-Scavenging

In this study, the authors evaluated the effectiveness of a new smart lipid system in stabilizing and delivering carotenes into the epidermis. The system is shown effective in providing free-radical (FR) scavenging at different stages of skin exposure: immediately neutralizing FR present in the skin, blocking FR formation during UV exposure, and accelerating skin recovery after UV exposure.

Safflower oleosomes are of interest in part because the plant seeds uniquely contain a large amount of oil bodies and low water content, resulting in decreased hydrolytic properties and lower protein degradation. The high oil content also creates low surface tension, increasing the oleosome’s ability to act as an emulsifier.

How Safflower Oleosomes Combine Sustainability, Emulsifying Efficacy and Barrier Benefits

Sustainably sourced safflower oleosomes are explored here for their multifunctionality as natural emulsifiers and for barrier benefits. Tests for stability and TEWL, skin water content and thickness, and ceramide and fatty acid effects are described.
