Vitamin A has always been known as the eye vitamin. Amongst the different forms it may take, retinal and retinol possess vitamin A activity. Retinol, the alcohol form of vitamin A, functions as a storage for the vitamin which then is converted to retinal: the active metabolite in aldehyde form responsible for light absorption. Closely related in structure is retinoic acid. It is irreversibly synthesized from vitamin A but does not perform any action in the retina for visual operation. It does have however, a great impact especially when in direct contact with the skin. Vitamin A in fact has been known to bring outstanding benefits for the skin the way it does for the eyes. And to achieve better outcomes, vitamin A has been developed in forms to optimize its absorption in the skin, the most famous are the vitamin A creams.
Common teenage problems are acne breakouts while wrinkles are the most bothersome for aging people. For these troubles, vitamin A application is proven to reduce wrinkling or delay their appearance as well as lighten the intensity of stretch marks and scars. This is due to the anti-proliferative activity of vitamin A, and it may even contribute to treating psoriasis, the excessive sloughing off of cells. For skin excessively exposed to the sun, the skin might lose elasticity and may stimulate overproduction of melanin, a substance responsible for pigmentation. Vitamin A is still beneficial as it can aid in the production of the structural components of the skin and tone down pigment production.
These are just not claims purportedly pronouncing what vitamin A can do for the skin. Studies have constantly been conducted to prove the efficacy of vitamin A especially in wrinkle reduction. Doctors from Stanford University for one explored and examined the effectiveness of vitamin A in the form of retinol in elderly patients wherein one arm served as the control and the other one being the experimental arm. Skin biopsies were drawn from each participant to serve as a reference. Throughout the study, vitamin A was rubbed on the experimental arm for 24 weeks and observations were made and rated on every scheduled week. At the terminal day, skin biopsies were again taken to compare it from the condition of their skin prior to treatment and true enough, there was a dramatic decrease in the severity of creases and folds in the skin. A conclusive decision was made that vitamin A is efficient in improving wrinkling and may even promote sustainability during skin injury.
As mentioned above, retinoic acid is one vitamin A configuration that has special performance in the refinement of the skin. What is inevitable though is its potential to act offensively in skin cell differentiation especially when administered in an unregulated manner subsequently causing inflammation and unwanted irritation. To remedy this dilemma, milder forms of vitamin A are employed to bring about the same benefits with lesser side effects. Retinyl acetate and retinyl palmitate provide similar effects. Once in the epidermal cells, they are converted to retinol which is then oxidized to retinoic acid. It binds with the retinoic acid receptors in the epidermal cells and executes its activity. This type of process regulates the amount of retinoic acid production thus causing lesser unwanted events.
The advantages listed may be enticing especially when every one of us wants to maintain a supple, clear and firm skin. One might just have to be reminded that any difference does not happen overnight and in order to notice development, one must devote time, effort and finances to continue the treatment. It is always best to consult experts as this may take its toll in the long term.
