About Retinol

Retinol products for day use contain a small amount of UV protection. It is recommended to use a SPF +15 sunscreen with the product, because retinoids can increase the skin’s sensitivity to sunlight. The product may be irritating to the skin during the adjustment period. Therefore, we recommend starting with the day cream, and adding serum and eye cream after a few days. Once the skin has become accustomed to the retinol, i.e. you feel no discomfort, you are ready to start using retinol cream for night use. During the adjustment period, you can expect the skin to be reddish and slightly irritated. If this does not go away after a few days, you should consider whether you should continue to use retinol in your skin care routine. 

– Retinoids reduce fine lines and wrinkles by increasing the production of collagen. They stimulate the production of ​new blood vessels in the skin, which improves skin tone. Retinol evens out age spots and softens the skin, improves the skin barrier and thickness.

– Retinol inhibits the formation of free radicals, blocks active oxygen damage and improves the skin’s anti-ageing abilities

– Daily use of retinol can reduce the ageing effect of ​stress-related adrenaline in the skin. In addition, retinol can renew the epidermis (the top layer of the skin) after external stress, and provide fullness to the dermis (the next layer of skin). The effect of this is that the skin is smoothed out and gets fullness from the inside, while the skin’s elasticity is increased.

– Anti-aging improvements will not be visible until regular use has continued for at least 4 weeks.

– Retinol has been shown to have a positive effect on acne-prone and acne-scarred skin

– Retinol in skin care is a long-term routine to reduce wrinkles and signs of aging.

– After 9 months of using retinol, the fine lines around the eyes have been significantly improved

For optimal effect store your Retinol products in a dark place. Retinol is unstable and degrades easily when exposed to air and sunlight.

Retinoider

Retinoids includes vitamin A and compounds similar to vitamin A. Vitamin A is a group of compounds which are essential for many functions in the body. Depending on age, sex, and pregnancy human need somewhere between 0.35 and 1.1 g of vitamin A per day. The focus here will be on Retinoids and the skin.

Retinoids is a large group of biologically active substances which primarily perform their effect by influencing the genome. This impact takes place by means of specific retinoid receptors, of which there are two types: Retinoic Acid Receptors (RAR) and Retinoid X Receptors (RXR).

At the cellular level, Retinoids can stimulate cellular activity in a variety of skin cells such as keratinocytes, fibroblasts, melanocytes and Langerhans cells. This can result in positive effects such as increasing the protective function of the epidermis, reducing water loss (and thus dry skin), protecting collagen from degradation, and inhibiting the activity of certain enzymes responsible for the degradation of the extracellular matrix. In addition, some (primarily in vitro and animal experiments) studies have shown that some Retinoids have an antioxidant and anti-bacterial effect.

Many Retinoids are researched and have shown positive effects in relation to e. g. wrinkles, pigment spots and impure skin – and some side effects such as skin irritation and possible endocrine disrupting effect. As with everything else, it is about finding the right balance.

There are both natural and synthetic retinoids and they are often divided into three generations of retinoids based on their molecular structures.

Retinoids are usually fat-soluble compounds with a ring-shaped structure, on which there is a chain with alternating double and single bonds between the C atoms. At the end of the chain is the structure that most often makes the difference between the most well-known Retinoids.

Alone, Retinoids are often not very stable, which is why they are often stabilized in relatively complex raw materials by the raw material producer – where the retinoid content itself is typically between 1 and 10%. Thus, a cosmetic product can contain, for example, 5% of a retinoid raw material, and if this retinoid raw material contains 1 % Retinoid then the proportion of “pure” Retinoid in the finished product is 0.05%. It is different how manufacturers state the amount of retinoid – some state the proportion of the raw material (including solvents, stabilizers, and retinoid) and others state the proportion of “pure” Retinoid. In some cases, the raw material is also formulated in a special way, which can help for better skin penetration and / or a slower release and thus less risk of unwanted side effects.

It is often recommended to avoid the sun or to use sunscreen in conjunction with retinoid use – primarily because retinoids can be unstable in sunlight. However, there are also studies which show that some retinoids have a UV-filter effect as they absorb UV light.

Below, the most common Retinoids are reviewed.

Retonic Acid

Retinoic Acid may also be known as Tretinoin (the alltrans form of Retinoic Acid). The substance group at the end of the chain is here an acid group. The substance is banned from use in cosmetics in the EU (can be used in medicines) and is quite irritating to the skin – even at very low concentrations. Studies suggest that it is precisely this substance that is the primary cause of the side effects of retinoids in skin products. Retinoic Acid can be converted in the body to other retinoids (Oxoretinoids), which have not yet been studied to great extent.

RETINOL

Retinol or Vitamin A1 alcohol has an alcohol group at the end of the chain structure and has been assessed by SCCS (European Scientific Committee on Consumer Safety) in 2016 to be safe to use in face and hand products and rinse-off products at a concentration of 0.3% and in body lotions at a concentration of 0.05%.

Retinol can (depending on, among other things, the product formulation in which the molecule is) reach the lower layer of the epidermis, where there are living cells and where the cells divide and to a lesser extent it can reach the dermis and to a much lesser extent the subcutis. In the skin / body, Retinol can be (reversibly) converted (oxidized) to Retinal which can then be (irreversibly) converted (oxidized) to Retinoic Acid – the primary active form. Retinol can also be esterified with a form of fatty acid to form Retinyl esters. Retinol and Retinyl esters make up most of the natural forms of retinoids found in the body.

Retinol has a less powerful effect compared to Retinoic Acid – and minor side effects.

Retinal

Retinal is also known as Retinaldehyde and is very similar to Retinol, but instead of an alcohol group (-OH) it is an aldehyde group – which chemically is usually more reactive than e.g. an alcohol group and is crucial for the receptor-independent effect of Retinal, that some studies have shown (anti-bacterial effect).

In the body, Retinal is converted to Retinol (reversible) or to Retinoic Acid (irreversible). Retinal applied to the skin will be converted relatively quickly to Retinol and from there to Retinyl esters and will to a lesser extent be oxidized to Retinoic Acid. In addition, enzymes in the body’s intestines can convert (ingested) carotenoids into Retinal.

Retinal appears to be less well known in skin care, but according to studies it has a good effect (in some areas slightly better than Retinol) and apparently about as mild as Retinol in terms of unwanted side effects.

Retinyl Estere

This is a group of retinoids where an acid is coupled to the Retinol to form an ester bond, making the molecule more stable. Examples are Retinyl Palmitate and Retinyl Acetate – these two examples of Retinyl esters are included in the assessment from SCCS with the same conclusion. They often have a less potent effect and less risk of side effects, as they have a longer “path” to the more active forms of retinoids.

Retinoate estere

This relatively new group of retinoids basically consists of Retinoic Acid, to which an alcohol is coupled, so that the ester bond, so to speak, faces the other way in relation to the Retinyl esters. Examples are Retinyl Retinoate (which also belongs to the group of Retinyl esters), which consists of Retinoic acid and Retinol linked together via an ester bond and Hydroxypinacolone Retinoate (often sold under the tradename Granactive Retinoid, which contains 10% Hydroxypinacolone Retinoate and the remaining 90% is solvent), which has been shown to be more stable than some of the other retinoids. However, many studies with this substance have not yet been performed.
