Retinoids are a group of organic chemical compounds that are derivatives of vitamin A. There are several types of retinoids, including retinol, retinaldehyde, retinoic acid, and many other derivatives and metabolites.

Retinaldehyde (retinal) is a chemical compound from the group of retinoids, which is one of the active metabolites of vitamin A. In the human body, it plays an important role in the processes of cell growth and differentiation, and also affects the functioning of the visual system, or the control of immune and inflammatory processes. Retinoaldehyde is synthesized in the liver and stored in fatty tissues, from where it is released into the bloodstream for transport to other tissues and organs.

Retinoids are used in medicine to treat skin conditions such as acne and psoriasis, and to treat some cancers. They can also be used in cosmetics due to their skin revitalizing and regenerating properties.

Retinoids are often used in dermatology because they have many beneficial effects on the skin. Here are some of them:

• Improves skin texture:

Retinoids help to reduce the appearance of wrinkles, scars and discoloration of the skin, as well as improve its elasticity.

• Counteract acne:

Retinoids reduce the production of sebum and prevent the formation of blackheads, making them effective in treating acne.

• Reduce discoloration:

Retinoids inhibit the production of melanin, which allows you to reduce the visibility of discoloration, such as age spots or freckles.

• Improve skin tone:

Retinoids stimulate cell renewal and remove dead skin cells, leading to a more even skin tone.

• They support protection against the harmful effects of UV radiation:

Retinoids can increase the thickness of the stratum corneum of the skin, which allows for better protection against the harmful effects of UV radiation.

Contraindications to the use of products with retinoids:

• Pregnancy and breastfeeding:

Retinoids can be harmful to the fetus, so they should not be used by pregnant or breastfeeding women.

• Hypersensitivity to retinoids:

Some people may be hypersensitive to retinoids and experience skin irritation and allergic reactions.

• Treatment of certain diseases:

Retinoids may be contraindicated in people with certain medical conditions, such as liver disease or kidney failure.

• Treatment of certain medications:

Retinoids can interact with certain medications, such as antibiotics or anticoagulants, which can lead to side effects.

• Use in combination with certain cosmetics:

Some cosmetics, such as chemical peels and toners, can increase skin irritation when used together with retinoids.

However, it is worth remembering that retinoids can sometimes be too irritating to the skin and cause irritation, especially in people with sensitive skin. Therefore, before starting to use retinoids, it is always worth consulting a dermatologist.
