Medicinal properties

Retinol palmitate is a compound that is natural to the body, so absorption occurs very quickly. In contrast, another form of vitamin A, retinol acetate, after entering the body, must go through several stages of synthesis before taking the form of palmitate.

Taking Retinol palmitate helps improve the general condition of the body. It normalizes vitamin A levels and improves many important biochemical reactions:

• Activates metabolism
• Accelerates redox processes
• Normalizes tissue metabolism
• Participates in protein synthesis
• Improves cell division, activates their renewal and regeneration
• Slows down keratinization
• Increases the body's resistance
• Improves the functions of the endocrine glands
• Activates intercellular connections.

As a result of the action of the substance:

• Hypo- and avitaminosis A is eliminated
• Strengthens the body's immunity and resistance
• Improves lipid and cellular metabolism
• Skin condition improves
• The functioning of organs and glands returns to normal.

In addition, vitamin A maintains the condition of the retina and is involved in the formation of rhodopsin, a visual pigment that ensures adaptation to darkness.

Retinol is almost completely absorbed in the intestines and distributed throughout the body. Most of all it settles in the liver and retina. It is also present in the kidneys and adrenal glands, and other organs. Vitamin A breakdown products are excreted through the kidneys. The drug leaves the body completely within a month. Therefore, if the drug was taken in high doses. This should be taken into account by women who are planning to become pregnant.

special instructions

Nuances for using vitamin A:

• It is prohibited to take vitamin complexes containing vitamin A (the risk of retinol overdose increases);
• When carrying a child or feeding it with breast milk, observation by a specialist is recommended.

With the simultaneous consumption of alcohol-containing drinks, the effectiveness of the vitamin is sharply reduced. It is not recommended to drive vehicles or perform work requiring increased concentration.

Drug interactions

Retinol palmitate (the instructions for use describe the existing contraindications for complex treatment with drugs) should be taken with caution when using the following medications:

• It is not recommended to take medications after long-term use of tetracycline antibiotics due to possible deterioration of the liver and a sharp increase in blood pressure;

• when taking cholesterol-lowering drugs, it is necessary to maintain an interval of 60-90 minutes before taking retinol (it increases the concentration of cholesterol);
• simultaneous use of oral contraceptives increases the level of vitamin A in the body;
• drugs that increase calcium and retinol content increase the concentration of the first medications, and an excess of calcium develops;
• taking vitamin A together with the drug Isotretinoin increases the likelihood of developing side effects of the latter remedy;

The simultaneous use of glucocorticosteroids, mineral-based laxatives and vitamin E can reduce the likelihood of developing side effects from taking retinol.

Pure retinol -

Real retinol, and not its esters, is already found in not too many cosmetic products. Moreover, very often manufacturers resort to deception - on the packaging in large letters they write that the product contains retinol, and in the ingredients in small print they may already write about retinol palmitate. The most important thing you should know about cosmetics with pure retinol is its concentration. Let's figure out which concentrations are effective.

1) Effective concentration of retinol –

We have already said above that the most effective form of vitamin A is “retinoic acid” (tretinoin). There are a large number of clinical studies that show that the optimal therapeutic concentration of tretinoin for the treatment of aging skin is 0.025%. And this is exactly the concentration recommended by the FDA (the most authoritative organization in the world that studies the effectiveness of pharmaceuticals and treatment methods). And as you will see below, this has a direct bearing on retinol.

Evidence base: 1) study “Griffiths CE, Kang S, Ellis CN et al. Two concentrations of topical tretinoin cause similar improvement of photoaging but different degrees of irritation." The study followed patients over 48 weeks and concluded that using a lower 0.025% tretinoin concentration for skin aging treatment had exactly the same effects as a higher 0.1% concentration. This is how the effective therapeutic concentration was determined.

2) Study “Olsen EA, Katz HI, Levine N et al. Tretinoin emollient cream: a new therapy for photodamaged skin. J Am Acad Dermatol 1992" shows that the use of products with tretinoin concentrations below 0.01% was not very effective. In this case, there was no significant difference in the condition of the skin before and after. And this also has a direct bearing on the effective concentration of retinol.

Important: the fact is that 0.1% pure retinol is approximately equivalent in effectiveness to 0.0025% tretinoin. It turns out that the 0.025% concentration of tretinoin recommended by the FDA for the correction of aging will correspond to 1.0% of pure retinol. That is why the world's leading manufacturers of anti-aging cosmetics with retinol, SKINCEUTICALS® and ZO® SKIN HEALTH, have products with 1.0% pure retinol in their lines. And these products are intended specifically for the correction of wrinkles in older patients.

Products with 0.3% pure retinol are suitable for correcting fine lines, as well as increasing skin elasticity, evening out skin tone and texture (products with 0.5% should add shallow wrinkles to the above). In addition, products with 0.1-0.3% pure retinol are suitable for correcting wrinkles in the corners of the eyes (while the 0.1% concentration is suitable for daily use, and 0.3% - only 3 times a week). The fact is that the skin around the eyes is thinner and more sensitive, and therefore lower concentrations will be effective here.

In addition, a 0.1-0.3% concentration can be used to prevent aging, as well as to acclimate the skin to retinoids (as a preparation before using a more concentrated 1.0% form of pure retinol).

2) Duration of use of retinol –

The study (“Two concentrations of topical tretinoin cause similar improvement of photoaging but different degrees of irritation” Griffiths CE, Kang S, Ellis CN et al.) shows that to achieve significant correction in older patients, the course of treatment should be at least 48 weeks .
If we are talking about an average correction, the duration of the course should not be less than 36 weeks. And in any case, for any patients, the course should not be less than 24 weeks. But there is one exception. Products with retinol can be prescribed for preparation before hardware rejuvenation methods, such as fractional RF lifting or laser resurfacing. In this case, even a 2-3 month course of pure retinol can significantly increase the effect of hardware methods. If you want to be guaranteed to get a pronounced anti-aging effect, and sooner than after 1 year, then the following scheme is suitable.

Carry out a course of 3 months with effective concentrations of pure retinol, after which do several fractional RF lifting procedures. These can be the following devices - 1) the “Venus Viva” device with a special “NanoFractional RF” applicator included in the kit, 2) a special tip for fractional grinding “Sublative RF”, which comes with the eTwo™ and Elos Plus™ devices. And it will be very effective.

3) Retinol microencapsulation technology –

If we talk about retinol esters, although they are not very effective, they have good stability. Those. the retinol in them is not destroyed by exposure to light and air. But pure retinol is quickly destroyed by both. Therefore, high-quality manufacturers use microencapsulation (or liposome) technology to stabilize pure retinol. In these cases, pure retinol molecules will be hidden in microcapsules or liposomes.

This protects pure retinol from degradation. When such technologies did not yet exist, high-quality manufacturers produced their products with pure retinol - only in opaque containers with a pump (dispenser). If retinol comes encapsulated, then such a dispenser is no longer needed. In addition, retinol in microcapsules has another excellent property - it significantly reduces the risk of skin irritation, which often occurs when using retinoids.

Important: many manufacturers of inexpensive cosmetics may not indicate the concentration of retinol at all. In addition, most manufacturers use non-encapsulated pure retinol in a cream or serum - and the product can come in a container without a dispenser, or in a transparent bottle (serum). Please note that if a manufacturer uses stabilized retinol in microcapsules or liposomes, this will always be written on the packaging. But don’t be confused: sometimes manufacturers write that their product contains a stable form of retinol, but we are talking about retinol palmitate, and not stabilized pure retinol (24stoma.ru).

Analogs

If the components of the capsules or solution are intolerant, they are replaced with medications:

• Retinol acetate. It is produced in the form of capsules, dragees, and solution for injection. There are no age restrictions for oral administration;
• Retinol. Available in a variety of forms. Has no age restrictions;
• Aevit. It is produced in the form of capsules, injection solution and ointment. Allowed for use after 14 years.

These drugs are prescribed by the treating specialist. Independent replacement of drugs is prohibited.

Similar drugs

The following drugs are similar in their mechanism of action:

• Videstim - ointment for external use;
• Retinol acetate in oil - vitamin A based on acetic acid salts;
• Aevit - with the addition of tocopherol.

The unique properties of retinol supplements allow the substance to be used in many areas. External use avoids the risk of overdose, but the concentration in such cases is lower and the effect is slower. Ingestion should be supervised by attending physicians.

General information

Retinol palmitate is a derivative of vitamin A and palmite salt. A fat-soluble substance that compensates for vitamin A deficiency in the body. The substance is not synthesized independently; it enters the body with food. The content in plant foods is lower than in animal foods. A shortage has serious consequences:

• premature aging of the skin, formation of wrinkles;
• the appearance of pimples, blackheads;
• increased susceptibility to infections;
• decreased reproduction;
• decreased functionality of the eye analyzer;
• increased fragility, hair loss;
• deterioration of tooth enamel;
• developmental delay in children.

Retinol based on palmite salt or ester is completely processed by the body. Unlike retinol acetate, synthesized using acetic acid. Manufacturers are different.
