Dimethicone 350 is a silicone oil consisting of a mixture of fully methylated linear siloxane polymers end-blocking with trimethylsiloxy units. Commonly used in skin and hair products.
Advanced glycation end products (AGEs) are compounds formed by non-enzymatic chemical reactions following the bonding of sugars to proteins or lipids during diabetes, uremia, aging, rheumatic arthritis, and other conditions. A receptor for the AGEs (RAGE) binds certain members of this class to initiate cell signaling.[1][2] Pentosidine is a well-characterized natural AGE that is often used as a biomarker for the production of all AGEs. While pentosidine can be measured in urine, the majority of this AGE is catabolized before excretion.[3]

Advanced glycation end products (AGEs) are compounds that are produced through non-enzymatic chemical reactions when sugars bond with proteins or lipids, occurring in conditions such as diabetes, uremia, aging, and rheumatic arthritis. A specific receptor, known as RAGE, interacts with select AGEs to trigger cell signaling. Pentosidine, a prominently studied natural AGE, serves as a common biomarker for assessing AGE production. Although pentosidine levels can be determined through urine analysis, it is predominantly broken down prior to excretion.
