Vitamin A derivatives (Retinoids) are very popular in cosmetics and skincare, as they may help to rejuvenate skin and improve overall appearance. Retinol (pictured above) is the alcoholic derivative of the group – extremely important for vision maintenance and function in the form of Retinal, the aldehyde derivative. Retinol is converted to Retinoic Acid on the surface of the skin, which allows for a higher cell turnover rate; cell turnover more or less means that more cells will be generated due to the decreased lifespan of the ones above it.
Like some other biomolecules, Retinal needs to be synthesized via Beta-Carotene. In this sense, Retinal is a “synthetic” product of a within the human body; further reaction may allow Retinal to transform into Retinol. A synthetic product means a derivation of a reaction, not necessarily “fake” as the term has come to be defined. Vitamin D, like Vitamin A, is synthesized through a series of steps from a starting material different than the final product.
Most of our JAMILA Cosmetics skincare products contain Vitamin A as a natural method to maintain and help replenish skin elasticity. These Vitamin A molecules are present as a result of the major ingredients used in the skincare. For example, we use a wide range of oils such as apricot, olive, jojoba, etc. and each oil has characteristic benefits – some of which contain vitamins.
Retinoic acid, which is a carboxylic acid derivative of Retinol, is the most common form of Vitamin A present in topical skin care creams and tonics. Care must be taken to monitor application, as a too high concentration or frequency of use may result in skin irritation or sensitivity; non-comedogenic and hypoallergenic sunscreen should be used while and after using topical Retinoids.
