Here's our rundown of the 5 factors that help determine whether a claim increases your car insurance rate. To a car insurance company, no 2 claims look alike. Having a shattered windshield replaced after a gravity-enamored branch takes a plunge is different from a major at-fault collision.
Retinol is an active form of vitamin A, a fat-soluble vitamin that is essential to vision and bone development. Sources include liver, whole milk, and fortified foods. The body can also convert it to retinal and retinoic acids as found in carotene compounds.
While both retinol and Retin-A contain retinoids, they differ in their concentration. Retinol and other forms, such as retinal and retinyl palmitate are found in many over-the-counter anti-aging creams. While these all contain a form of vitamin A, the concentration of retinoids is weak. Retin-A is a prescription retinoid and is a brand name for tretinoin, which is the carboxylic acid form of vitamin A and was one of the early topical acne treatments. Retin-A is sold by prescription because its acid composition is much greater than in over-the-counter products.
