Retinoids are known for their benefits in improving the appearance of skin and fighting the signs of aging. But what are they, how do they work and when is it appropriate to use them to make the most of their properties?
What are retinoids?
Retinoids are an important group of vitamin A-derived ingredients. They are commonly used in skincare products to combat signs of aging, hyperpigmentation, acne-prone skin and uneven texture. These active ingredients work by promoting cell renewal and stimulating collagen production, helping to smooth wrinkles, reduce blemishes and improve overall skin tone.
What is retinol?
Retinol is a type of retinoid, it is the pure form of vitamin A in alcohol and is the precursor for the synthesis of retinal and retinoic acid.
Which is the best retinoid for the skin?
The choice of the best retinoid for the skin will depend on the specific objectives we are looking for. It should be understood that retinoic acid is the active form of vitamin A that allows it to carry out its action on the skin. This retinoic acid is a medicine and is therefore subject to medical prescription. The retinoids used in cosmetics (such as retinyl, retinol and retinal) need to be converted to this form in the skin in order to carry out their action. This happens through a conversion cascade in this order: retinyl – retinol – retinal – retinoic acid.
Therefore, depending on the ingredient used, it will take more or less time to transform and generate its benefit. Generally speaking, retinyl provides a delayed action, retinol offers a continuous action, while retinaldehyde or retinal has a more immediate action.
Retinoids can cause skin irritation on first application and are chemically unstable in contact with oxygen and UV radiation. For this reason, if we use retinoid products, we recommend applying them at night and starting progressively to minimize possible dermatitis. At Sesderma, thanks to Nanotech technology and its encapsulation of active ingredients in liposomes, we achieve formulas with high tolerance, stability and efficacy that can be used even during the day.
When is it appropriate to use retinoids?
Retinoids are among the top active ingredients used in the field of dermo-cosmetics because they are among the most complete and effective. They improve the appearance of fine lines, combat loss of elasticity, provide radiance, reduce blemishes, contribute to sebum regulation and improve skin texture.
If in doubt, consult a dermatologist before incorporating retinoids into a skincare routine. Retinoids are not recommended during pregnancy.
How do retinoids work?
Retinoids work by accelerating skin renewal. That is, they stimulate skin regeneration and normalise keratinisation, increase collagen synthesis and prevent its degradation. They can also decrease melanin synthesis and excess oiliness. These processes help to reduce the appearance of wrinkles, improve texture and reduce spots caused by sun exposure or aging.
What causes collagen in our skin and why is it important?
Collagen is an essential protein that provides structure and firmness to the skin. As we age, collagen production decreases, contributing to the appearance of wrinkles and loss of elasticity. Retinoids help stimulate collagen production and slow collagen breakdown, keeping skin firmer and reducing the signs of aging. This increase in collagen is key to maintaining youthful-looking skin.
How often should I use them?
The frequency of retinoid use depends on skin tolerance and the type of retinoid. For those starting with retinoids, it is recommended to start by applying them in the evening twice a week, on non-consecutive days, and gradually increase the frequency as the skin becomes accustomed to the active ingredient.
The encapsulation of retinoids in liposomes greatly improves their tolerance. In addition, we achieve rapid penetration, with deep action and sustained release.
It is essential to use sunscreen during the day when using retinoids, as the potential skin irritation associated with the use of these ingredients may increase the possibility of skin burn with sun exposure.
