Retinoic Acid Powder

What Is retinoic acid powder?

Vitamin A itself comes only from food and cannot be manufactured in any animal. It is esterified and stored in the liver, the richest source of vitamin A outside of supplements.

Retinoic acid powder is synthesized from retinol by two enzymatic reactions, the first being the reversible oxidation of retinol to retinal, followed by the second irreversible oxidation to retinoic acid.

Like other retinoids, retinoic acid powder is a photosensitive compound due to the presence of alternating double bonds between the carbon atoms in its hydrophobic tail, attached to a 6-carbon ring. The compound's low molecular weight also makes it highly fat-soluble, meaning it diffuses easily across cell membranes.

The effect of retinoic acid powder

1. Repair skin and relieve aging

Vitamin A acts on the skin's epidermis to promote cell reproduction, maintain normal skin circulation, repair lost collagen, reduce wrinkles, and relieve signs of premature aging (such as abnormal pigmentation, rough spots, and dry skin).

2. Promote cell growth

Retinoids are important biomolecules involved in cell growth, maturation, apoptosis and immune function. In addition, retinoic acid is essential for organ development and visual function in embryonic life. Retinoids like retinoic acid help shift cell types from a proliferative to a mature mode by inducing differentiation.

Retinoic acid powder is bound intracellularly by binding to the cellular retinoic acid binding protein (CRABP) and in the nucleus by two types of receptors, the retinoic acid receptor (RAR) and the retinoic acid X receptor (RXR ). Retinoic acid exists in several biologically active forms that can isomerize under physiological conditions. Different isomers act on different receptors.

Transformation Mechanism of Vitamin A and Its Derivatives

Vitamin A in the human body usually comes from the vitamin A precursor in food - β-carotene, which is cut into two cis-retinal by the BCMO1 enzyme in the human body, and the further reaction of retinal can generate retinoic acid or Retinol, which is further converted in the body to retinyl palmitate or retinyl acetate, is present in very low levels of these molecules.

Retinol molecules in the human body accumulate in the form of retinol esters, or eventually undergo a two-step oxidation to retinoic acid (first oxidized to retinal, which is then oxidized to retinoic acid), and retinoic acid is lipophilic Its chemical properties allow it to penetrate the intercellular space of the epidermis, interact with retinoic acid receptors, stimulate the skin regeneration process, and improve the physiological properties of the skin. Since it is retinoic acid that really plays a role in skin anti-aging, exogenously supplemented retinol, retinal, and retinol esters will be converted into retinoic acid by enzymes on the skin surface, Xanthoic acid receptor binding exerts biological activity. The conversion process will be affected by enzyme activity, local transmission and stability, and the molecules are sorted from large to small according to biological activity as retinoic acid, retinal, retinol, retinol ester, which shows that retinol ester is the most stable form.
