Retinol is vitamin A. It was discovered in 1913. It is a fat-soluble substance and therefore accumulates in the body. In uncontrolled doses it causes toxic reactions and overdose. Participates in more than 30 biological processes: from sperm maturation to regulation of skin renewal processes. Neither man nor animal can live and develop without this substance. A deficiency or excess of the vitamin threatens a huge number of pathologies. Retinol is called a hormone-like substance because it acts on human cell receptors. Of course, in its pure form it is not capable of this. To act on cells, Vitamin A must enter the body and be converted into its active form - retinoic acid.
Contraindications and possible side effects
Before taking retinol, you need to familiarize yourself with the contraindications. These include:
- individual intolerance to components;
- acute or chronic nephritis;
- decompensation stage of heart failure;
- chronic pancreatitis;
- detection of kidney stones;
- excessive retinol content in the blood;
- exceeding intracranial pressure readings.
Before using the drug during pregnancy and breastfeeding, you should consult your doctor. Vitamin A tablets should be used with extreme caution in cases of liver cirrhosis, renal failure, viral herpes, and in old age.
Retinol tablets, if recommended dosages are exceeded, can provoke adverse reactions such as headaches, rashes, and dry eye syndrome. Excessive intake of vitamin into the body can make a person irritable. Sometimes an adverse reaction manifests itself in the form of cracking lips and flaking of the skin.
Russian-made products
Companies involved in the production of cosmetics in Russia do not produce preparations with modern forms of vitamin A: microencapsulated or liposomated pure retinol. Production is labor-intensive and the cost of such products will be high.
Creams, serums and gels use retinol esters (retinyl palmitate), they are not as effective, but are resistant to light and air. The pharmacy sells Videstim ointment with 0.5% retinol palmitate or Radevit Active with 1% concentration.
CAVIALE Vitamin A
The Russian company produces a cream whose recipe, in addition to vitamin A, contains vitamin E, retinyl palmitate, shea butter, macadamia (a nut with B vitamins) and other components. The cream has a light texture, spreads well and is absorbed. The main function of the product is to even out the tone and moisturize. The manufacturer does not recommend applying the cream to wounds and abrasions, as well as for dermatological diseases.

It is recommended to additionally use masks for oily skin and review your daily diet.
Interaction with other drugs
The vitamin should not be taken during long-term use of tetracyclines. Violation of this recommendation may result in increased intracranial pressure. The absorption of vitamin A is reduced during the use of cholestyramine, colestipol or mineral oils, which may lead to an increased need for the vitamin. A similar effect is observed when taking vitamin E. Its consumption in large quantities reduces the duration of vitamin A storage in the liver and reduces the effectiveness of its use. At the same time, it also has a positive effect associated with a decrease in the toxicity of retinol, which, on the contrary, increases with the use of isotretionine. Preoral contraceptive drugs can lead to an increase in the concentration of vitamin A in the blood plasma.

Retinol (vitamin A) in cosmetics
The cosmetics market is developing faster than any other. Our grandmothers never dreamed of the amount of cosmetics that every self-respecting woman has today. Even if you are not a beauty blogger, you probably have at least 10 skincare products on your bathroom shelf.
However, despite such powerful care, almost every woman has encountered the fact that the product does not work as desired, or, worse, irritation occurs, dryness and sensitivity worsen, etc. For example, after using retinoids instead of a lifting effect and recovery, you can easily get redness, peeling and pigmentation. We will now tell you why this happens and how to avoid it.
The correct form of retinol
In order to get a rejuvenating effect, you should choose both a working and a safe form of retinoids. To understand the issue, let's look at the chain of transformation of retinoids on the skin:
Retinyl Esters (like retinyl palmitate) > Retinol > Retinaldehyde/Retinal > All-Trans-Retinoic-Acid/Tretinoin.
Retinyl palmitate is converted by enzymes to retinol, then retinol is converted to retinaldehyde and, ultimately, to the “working” form of retinoic acid, which can affect cellular structures. That is, the more steps it takes to convert (and there can be losses at each step), the less effective the retinoid form is.
Anti-aging cosmetics
All cosmetics with vit. And it has a rejuvenating effect. However, there are differences in the mild effect (prevention) and the strong visible effect (treatment). Depends on the concentrate.

Metabolism of retinoids in the skin
The metabolism of retinoids (retinol, retinaldehyde and retinoic acid) was studied in cultured human skin and skin fibroblasts from biopsies.
Research methods : radioactive and liquid chromatography.
Results were assessed 24 hours after application:
- 75% of retinoids were localized in the epidermis
- 20% in dermis

Summary : the concentration of retinoids that can potentially penetrate to the level of the entire body is negligible!
