Product Details:

Vitamin A is a vitamin that is needed by the retina of the eye in the form of a specific metabolite, the light-absorbing molecule retinal. This molecule is absolutely necessary for both scotopic and color vision. Vitamin A also functions in a very different role, as an irreversibly oxidized form retinoic acid, which is an important hormone-like growth factor for epithelial and other cells.

Retinyl palmitate has been used in skin cremes, where it is broken down to retinoic acid, which has potent biological activity, as described above.

The retinoids, (for example, 13-cis-retinoic acid) constitute a class of chemical compounds that are related chemically to retinoic acid, and used in medicine to modulate gene functions in place of this compound. In general, like retinoic acid itself, these compounds do not have full vitamin A activity.
