What is Retinol?

Retinol is a natural form of vitamin A. It is a diterpenoid and an alcohol. Retinol could be converted to other forms of vitamin A such as retinaldehyde (retinal). The chemical formula of retinol is C₂₀H₃₀O. Its molar mass is 286.46 gmol⁻¹。Retinol is biosynthesized from β-carotene. Since retinol is a natural form of vitamin A, it has many biological roles.

在生物系统中，视网膜A在衰老中起主要作用。视网膜A在皮肤病学和癌症治疗领域具有药用。在皮肤病学中，视网膜A是痤疮的良好固化剂。它也可以作为脱发，去除皱纹和皮肤衰老缓慢的治疗方法。在癌症治疗中，视网膜A具有可用于治疗急性寄生虫细胞白血病。

What are the Similarities Between Retinol and Retin A?

Both retinol and Retin A are derivatives of vitamin A.
They are retinoids.
Thus, both forms are used as therapeutics in the field of dermatology.

What is the Difference Between Retinol and Retin A?

视黄醇和成分是维生素A是类维生素A的一种。However, retinol is a natural form of vitamin A. On the other hand, Retin A is a synthetic form of vitamin A. Thus, we can consider this as the key difference between retinol and Retin A. Furthermore, Retinol is a chemical name while Retin A is a brand name for the medication tretinoin. Hence, this is also a difference between retinol and Retin A.

Considering the chemical properties, the molecular mass of retinol is 286.46 gmol^-1while the molecular mass of Retin A is 300.44 gmol^-1。Chemically, this is one difference between retinol and Retin A. Furthermore, the chemical formula of retinol is C₂₀H₃₀O while the chemical formula of Retin A is C₂₀H₂₈O_2.Moreover, a further chemical difference between retinol and Retin A is that the retinol has a lower melting point while it is high in Retin A.
