This survey of recent literature relates to assessing hair damage, reducing dye allergy, increasing and inhibiting hair growth, cleansing and conditioning hair, and more. The papers are presented as food for thought in the early stages of the product development process, and may warrant deeper investigation.

Fatty acid bile acid conjugates (FABACs) have been found to affect skin by enhancing ATP-binding cassette (ABCA1) cholesterol transporter and competitively inhibiting stearoyl-CoA desaturase (SCD1) enzyme. Based on the mechanisms involved, detailed here, the authors developed a new FABAC and tested it in vitro. Results suggest its potential as an anti-aging and anti-acne active.

Sun exposure leads to the production of free radicals in skin and to damage to elastin and collagen, resulting in premature aging. Studies of consuming carotenoid-rich fruits and vegetables have shown lower incidences of skin pathology. Carotenoids are among the most efficient natural scavengers of free radicals and may be used as oral sun protection, as is discussed here.

Recent studies demonstrate that the skin microbiome of infants actively changes during the first year of life, along with evolutions in skin structure, biochemical composition and function. These dynamics in the development of a healthy skin microbiome must be taken into consideration when designing products for baby skin care.

Considering the potential for reactions between cosmetics and hypersensitive skin, the present article will focus on this skin type; first by outlining mechanisms of type I and IV hypersensitization, then by focusing on type I immunogenic vs. non-immunogenic urticaria. Potential urticariogens in cosmetics are considered, and suggestions for future direction are given.
