What are Retinoids?
Retinoids are a class of chemical compounds that are derived from Vitamin A, or retinol, and exhibit a similar biological activity. Chemically, they share a core structure known as the retinyl group, which allows them to interact with specific cellular receptors in our skin. This unique ability makes retinoids particularly effective in treating various skin concerns.
Retinoids have a well-established role in skincare, thanks to their diverse range of benefits. They have been proven to be an effective acne treatment and a great way to alleviate hyperpigmentation, and signs of aging, such as fine lines and wrinkles. These versatile compounds owe their success to their ability to regulate cellular processes, including cell differentiation, proliferation, and apoptosis, which are essential for maintaining healthy skin.
How Retinoids Work?
Retinoids work by interacting with two families of nuclear receptors: retinoic acid receptors (RARs) and retinoid X receptors (RXRs). These receptors function as transcription factors, regulating the expression of genes involved in cellular processes that contribute to skin health.
When retinoids bind to their specific receptors, they modulate the activity of target genes, which in turn leads to changes in cellular behavior. This can result in increased cell turnover, reduced sebum production, and enhanced collagen synthesis, all of which contribute to improved skin appearance and texture.
In summary, retinoids are biologically active compounds derived from Vitamin A, which exert their skin-improving effects through interactions with cellular receptors. Their ability to modulate gene expression leads to various benefits, including the treatment of acne, hyperpigmentation, and signs of aging. Understanding the different types of retinoids and their specific actions is essential for choosing the right product for your skincare needs.
Who Can Benefit from Using a Retinoid
A wide range of individuals can benefit from using retinoids as a topical treatment in their skincare routines. Those who experience mild to moderate acne, uneven skin tone, hyperpigmentation, or signs of aging, such as fine lines and wrinkles, may see significant improvements with the use of retinoids. Additionally, retinoids can also be effective in addressing skin texture issues and promoting a more radiant complexion.
Who Should Not Use Retinoids
Despite their numerous benefits, retinoids may not be suitable for everyone and can cause adverse reactions in some folks. Individuals with very dry skin, highly sensitive skin or skin conditions such as rosacea, eczema, or psoriasis should exercise caution when using retinoids, as they may exacerbate irritation and inflammation. Pregnant or breastfeeding women should also avoid using retinoids, as some forms of retinoids have been associated with an increased risk of birth defects. It is always advisable to consult with a dermatologist or healthcare professional before incorporating retinoids into your skincare routine, especially if you have any concerns or underlying skin conditions
Different Types of Retinoids
As we’ve explored the world of retinoids, you may be wondering about the various types available and how they differ from one another. In this section, we’ll dive into the diverse range of retinoids, examining their specific uses, potencies, and the factors to consider when choosing the right one for your unique skin concerns.
Retinol
Retinol is the most common over-the-counter (OTC) form of retinoid, and it’s often found in various skincare products, such as serums and creams. As a less potent derivative of Vitamin A, retinol requires conversion into retinoic acid within the skin to become biologically active. This conversion process results in a milder effect, making retinol a popular choice for those who are new to retinoids or have sensitive skin. Because retinol tends to be a mild and less irritating than others on this list, it’s often the first retinoid many will try.
Here are may favorite (and most highly reviewed OTC retinols):
Adapalene
Adapalene (also known as differin gel) is a prescription-strength synthetic retinoid that is available as over the counter products and by prescription, depending on the concentration. It is commonly used to treat acne, as it is particularly effective in unclogging pores and reducing inflammation. Adapalene is also known to be less irritating than some other retinoids, making it a suitable option for individuals with sensitive or acne-prone skin.
Here is the best Adapalene gel you can get (this is the one I use and my dermatologist recommended):
Tretinoin
Tretinoin, also known as all-trans retinoic acid, is a prescription-strength retinoid that has been widely used for decades to treat acne, sun damage and signs of aging. As a more potent form of retinoid, tretinoin provides faster and more noticeable results than its OTC counterparts. However, it can also cause more irritation and may require a gradual introduction into a skincare routine to minimize side effects.
Tazarotene
Tazarotene is another prescription-strength retinoid that is used primarily to treat acne, acne scars, psoriasis, dark spots, and signs of aging. It is known to be one of the most potent topical retinoids available and provides significant improvements in skin texture and tone. Due to its strength, tazarotene may cause more skin irritation than other retinoids and is typically reserved for those with more severe skin concerns or who have already built up a tolerance to milder retinoids.
Isotretinoin
Isotretinoin, often referred to by its brand name Accutane, is an oral retinoid that is prescribed for severe acne or cystic acne that has not responded to other treatments. It works by reducing sebum production and has been shown to provide long-lasting results for many patients. However, isotretinoin carries a risk of significant side effects, including birth defects, possible toxicity, and requires close medical supervision during treatment.
Over-The-Counter vs Prescription Retinoids
The primary difference between OTC and prescription retinoids lies in their strength and potency. OTC retinoids, such as retinol and low-concentration adapalene, are typically milder and less likely to cause irritation. They can be a good starting point for those new to retinoids or with sensitive skin. In contrast, prescription retinoids, such as tretinoin, tazarotene, and isotretinoin, are more potent and may provide faster, more dramatic results. However, they also carry a higher risk of side effects and should be used under the guidance of a dermatologist or healthcare professional.
Adapalene: A Closer Look
Adapalene primarily targets retinoic acid receptors (RARs), specifically RAR-beta and RAR-gamma, which play crucial roles in regulating skin cell growth and differentiation. By binding to these receptors, adapalene normalizes the processes of keratinocyte differentiation and reduces the formation of microcomedones, which are the precursors to acne lesions. Furthermore, adapalene has notable anti-inflammatory properties, making it particularly effective in reducing the redness and swelling associated with acne.

In conclusion, both adapalene and retinol offer unique benefits and uses for addressing various skin concerns. Understanding the differences between these two retinoids and how they interact with your skin can help you make an informed decision and achieve the best results for your specific needs.
Retinol in the Diet
While topical retinoids like adapalene and retinol have a significant impact on our skin’s health and appearance, it’s essential not to overlook the role of diet in supporting our skin from within. In fact, research has indicated that acne and other skin conditions are often a result of internal issues largely caused by diet and lifestyle. For more one this, be sure to check out my article on diet and acne. In this section, we’ll discuss the importance of dietary retinol and other sources of vitamin A, as well as the differences between dietary vitamin A and dietary retinol, and how they contribute to our skin’s overall health.
Dietary Vitamin A vs. Retinol
While retinol is a form of vitamin A, your body treats both vitamin A and retinol fairly differently so let’s quickly compare the two.
- Dietary vitamin A: Vitamin A is an umbrella term that encompasses both preformed vitamin A (retinol) and provitamin A carotenoids, such as beta-carotene. Provitamin A carotenoids are found in plant-based foods and need to be converted by the body into retinol before they can be utilized. However, this conversion process is not very efficient. Studies have shown that only a small percentage of ingested carotenoids are converted into retinol, and the rate can vary widely between individuals depending on factors such as genetics and overall health. As a result, relying solely on plant-based sources of vitamin A may not provide sufficient amounts of retinol to fully support skin health.
- Dietary retinol: Retinol is the preformed version of vitamin A found in animal-based foods. Unlike provitamin A carotenoids, retinol is readily absorbed and utilized by the body without the need for conversion. This means that consuming dietary retinol can have a more immediate and direct impact on skin health compared to ingesting provitamin A carotenoids. The higher bioavailability of retinol ensures that the body receives adequate levels of this essential nutrient to support skin cell turnover, production of collagen, immune function, and other processes vital for maintaining a healthy, radiant complexion.
In summary, while both dietary vitamin A and dietary retinol play crucial roles in supporting skin health, the bioavailability of retinol makes it a more efficient and reliable source of this vital nutrient. By consuming a balanced diet that includes both animal and plant-based sources of vitamin A, you can ensure that your body receives adequate levels of retinol to optimize skin health and complement the benefits of your topical retinoid treatments.
Sources of dietary retinol and vitamin A
Dietary retinol, or preformed vitamin A, is primarily found in animal-based foods such as liver, fish, dairy products, and eggs. On the other hand, provitamin A carotenoids, like beta-carotene, can be found in plant-based foods, including sweet potatoes, carrots, spinach, and kale. Once ingested, the body can convert these carotenoids into retinol.
Note that dairy products and eggs can trigger acne in some individuals so your safest bets for getting retinol in your diet are fish and organ meats. Really though, the highest levels of retinol are present in liver. Which means that if you’re trying to incorporate more retinol into your diet, liver may be the best way to go.
Not to worry, if you are like me and shudder at the thought of eating liver, there are supplements available that are (mostly) tasteless and odorless. This is the one that I use and personally have noticed tremendous improvements to my skin after taking them daily:

Benefits of Dietary Retinol and Vitamin A for Skin Health
Dietary retinol and vitamin A play a critical role in maintaining healthy skin. They contribute to cell growth and differentiation, collagen production, and immune function, all of which are essential for maintaining a youthful, radiant complexion. A diet rich in retinol and vitamin A can help to:
- Support skin cell turnover, which may reduce the appearance of fine lines, wrinkles, and uneven skin tone.
- Promote collagen synthesis, leading to firmer, more elastic skin.
- Strengthen the skin’s natural barrier, which can help to protect against environmental aggressors and prevent moisture loss.
- Boost the immune system, reducing inflammation and the risk of acne breakouts.
Recommended Daily Intake and Precautions
The recommended daily intake of vitamin A varies depending on age, sex, and life stage. In general, adult men need approximately 900 micrograms (mcg) of retinol activity equivalents (RAE) per day, while adult women need about 700 mcg RAE daily. Pregnant and breastfeeding women have higher vitamin A requirements.
It’s important to note that excessive intake of preformed vitamin A (retinol) can be toxic, leading to a condition called hypervitaminosis A. Symptoms may include dizziness, nausea, and even hair loss. Therefore, it’s crucial to consume vitamin A within the recommended limits and maintain a balanced diet.
In conclusion, a diet rich in retinol and other sources of vitamin A is vital for maintaining healthy, youthful-looking skin. By understanding the differences between dietary vitamin A and dietary retinol and ensuring a balanced intake of these essential nutrients, you can support your skin from within and complement the benefits of your topical retinoid treatments.
Tips for Integrating Retinoids Into Your Skincare Routine
Incorporating retinoids into your skin care routine can seem daunting, especially given the potential side effects and the wide variety of products available. To help you get started and maximize the benefits of retinoids, we’ve compiled some practical tips for introducing these powerful ingredients into your skincare regimen.
Choosing the right retinoid
- Assess your skin concerns and goals: Determine whether your primary focus is on acne, hyperpigmentation, fine lines, or wrinkles. This will help you decide which type of retinoid is most suitable for your needs.
- Start with a milder retinoid: If you’re new to retinoids or have sensitive skin, consider starting with an over-the-counter retinol product. This will allow your skin to adjust to the active ingredient gradually.
- Consult with a professional: A board-certified dermatologist or healthcare professional can help you choose the right retinoid based on your skin type, concerns, and goals.
Introducing retinoids gradually
- Begin with a lower concentration: Starting with a lower concentration of retinol or adapalene can help minimize irritation and allow your skin to adjust to the new ingredient.
- Apply every other day or less frequently: Rather than using a retinoid daily, start by applying it every other day or even just once or twice a week. Gradually increase the frequency as your skin becomes more accustomed to the product.
- Use a pea-sized amount: A little goes a long way with retinoids. Using too much can increase the risk of irritation. Start with a pea-sized amount and spread it evenly across your face, avoiding the eye area.
Proper skincare routine
- Cleanse your skin: Before applying a retinoid, make sure your face is clean and dry. This will help the product absorb more effectively.
- Use a moisturizer: Retinoids can cause dryness, so it’s essential to moisturize your skin regularly. Apply a moisturizer after your retinoid treatment to help combat dryness and irritation.
- Apply sunscreen: Retinoids can increase your skin’s sensitivity to the sun. Be sure to use a broad-spectrum sunscreen with an SPF of at least 30 daily to protect your skin from sun damage.
Be patient and consistent
- Give it time: Retinoids can take several weeks or even months to show noticeable improvements. Be patient and don’t expect overnight results.
- Stick to your routine: Consistency is key with retinoids. Skipping applications or using the product sporadically can hinder your progress and make it more difficult for your skin to adjust to the ingredient.
