What is All-trans Retinal?

All-trans Retinal, also known as retinal or vitamin A aldehyde, is a form of vitamin A that is oxidized by all-trans retinol. It was originally called retinene and was renamed after it was found to be vitamin A aldehyde. It is a polyene chromophore that binds to a protein called opsin and is the chemical basis of animal vision. As an important signal transduction molecule in the animal eye, it has many different important functions. All-trans Retinal can be used as an intermediate for β-carotene. It is corotenoid component of the visual pigments. It is converted to retinoic acid in vivo by the action of retinal dehydrogenase. Retinoic acid has an important role in the treatment of skin diseases, but its clinical application has been limited due to its irritation to the skin. all-trans Retinal is an intermediate metabolite of natural retinoic acid. Its biological activity is similar to retinoic acid, but it is much less irritating to the skin than retinoic acid.

The benefits of All-trans Retinal

All-trans Retinal can directly interact with protein receptors in the cell, stimulate the skin epidermis to accelerate renewal, increase the thickness of the stratum corneum, and make the skin firmer; meanwhile, it can accelerate the production of collagen in the dermis and prevent the destruction of collagen by ultraviolet rays. Suppressing the increase of MMP caused by ultraviolet rays makes the skin more elastic; the unique aldehyde structure has a strong inhibitory effect on P. acnes and can effectively improve acne skin.

all-trans Retinal has many functions in skin care, such as anti-aging, skin rejuvenation, whitening, anti-wrinkle, acne, exfoliation and other multiple functions. It is widely used in skin care products and is a new and highly effective natural active. However, all-trans Retinal is difficult to dissolve in water and is easily oxidized. These disadvantages limit its application in cosmetics. Taian Green Industry Co., Ltd uses nano-transmission system (NDS) to develop nano-active materials with a particle size of less than 30 nm. By allowing retinal to be stably wrapped in a nanocarrier, it can greatly increase absorption efficiency and bioavailability, overcome shortcomings and maintain advantages, and make the application of all-trans Retinal more convenient and extensive.

How do we get All-trans Retinal?

In general, we don't need to deliberately supplement all-trans Retinal, because we can get enough all-trans Retinal through daily intake of meat and carrots. The retina of our eyes helps us convert carotene into all-trans Retinal.
