Retinol is one of the most popular ingredients when it comes to skincare and cosmetics. The benefits of retinol are manifold and it is the solution to many skin problems today. Retinol neutralizes free radicals as well as fights the signs of premature aging. Moreover, hyaluronic acid can be used with retinol to mute some of the side effects that come with it. It takes time for the skin to get used to retinol, but once it does, this ingredient can be used daily without any hassle.
Origin
Retinol is made by the hydrolysis or acidification of retinal. The retinal is originally obtained by the reduction of a derivative of pentadiene. Being a derivative of vitamin A, retinol is quite beneficial for the skin.
Safety profile
Retinol is good for skin and is free from side effects. However, it can cause irritation and extreme dryness if used for the first time since the skin takes time getting used to this ingredient. To reduce the side effects of retinol it is recommended to use it every third night and work your way up from there. Similarly the percentage of retinol used at the beginning should not be more than 0.025, which can be increased with time.
