Imagine a treatment that doesn’t just cover up acne but actually tackles the root causes behind it. Oral retinoids are powerful vitamin A derivatives that work systemically to not only reduce oil production, unclog pores, and calm inflammation but also influence cell growth and differentiation. By guiding skin cells to mature and shed normally, they help restore proper skin function and prevent the buildup that leads to acne. Unlike topical treatments that only work on the surface, these medications work throughout your body, making them a highly effective option for severe or stubborn acne.
Meet the Main Players
Isotretinoin (Accutane)
Isotretinoin is the most widely prescribed option for severe, treatment-resistant acne. It works by shrinking your sebaceous glands, significantly cutting down on oil production. It also normalizes skin cell turnover and helps reduce the bacteria behind acne.
Realistic Timeline for Results:
Noticeable improvements can appear within 1-2 months, with dramatic clearing often seen in 4-6 months. During this phase, some patients experience what’s known as “skin purging,” where the skin temporarily worsens before it gets better. This process signals that the treatment is kick-starting a more effective skin renewal. For a deeper dive into skin purging, check out our special article, Skin Purging – What You Need to Know.
Side Effects:
Common issues include dry skin and lips, slight joint discomfort, and increased sensitivity to sunlight.
Acitretin (Soriatane)
Primarily used for psoriasis, acitretin isn’t typically a first choice for acne due to its limited effectiveness in this area. Side effects can include dryness, hair thinning, and potential liver concerns.
Oral Tretinoin
This option is rarely prescribed for acne because safer alternatives, like isotretinoin, are available.
Why Is Isotretinoin Such a Game-Changer?
Isotretinoin, often recognized by its brand name Accutane, has reshaped the way we approach severe acne treatment. It works on multiple fronts—reducing oil gland size, lowering bacterial presence (Cutibacterium acnes), and fighting inflammation. Many patients notice significant improvements not just in their skin’s appearance but also in overall skin health.
Busting the Myths
Let’s clear up a few common misconceptions about oral retinoids:
Myth #1: “Isotretinoin causes depression.”
The Truth: Recent studies show little to no direct link between isotretinoin and depression. In fact, for many, clearing severe acne can lead to improved mental well-being.
Myth #2: “Oral retinoids permanently cure acne.”
The Truth: While many experience long-term remission, some might require additional courses or maintenance treatments to keep their skin clear.
Myth #3: “You cannot get pregnant for a year after taking oral retinoids.”
The Truth: Strict pregnancy prevention measures are essential during treatment and for at least one month after discontinuation due to isotretinoin’s high risk of birth defects. However, the idea that you must avoid pregnancy for an entire year is a misconception. If pregnancy occurs during this high-risk period, it can lead to severe birth defects—hence, the need for regular pregnancy tests and effective contraception under programs like iPLEDGE.
Is This Treatment Right for You?
Oral retinoids aren’t a one-size-fits-all solution. They’re particularly effective for individuals whose severe acne has resisted other treatments. If your usual topical creams and antibiotics haven’t delivered the results you’re hoping for, oral retinoids might offer the comprehensive, inside-out approach you need.
There’s also a common concern regarding acne scarring. Many worry that severe acne or its treatment might worsen scarring. In reality, while severe acne can lead to scars, oral retinoids are typically prescribed to reduce the risk by targeting excess oil, reducing inflammation, and promoting healthy skin turnover.

Additionally, be aware that oral retinoids can come with side effects—most commonly dryness, photosensitivity, and occasional joint pain.
Skincare Routine While on Oral Retinoids
When you’re on oral retinoids, your skin is more sensitive and prone to dryness. Adopting a gentle, supportive skincare routine can go a long way in minimizing irritation and maintaining a healthy complexion. Here are some key points to consider:
- Gentle, Non-Irritating Cleanser
Opt for a mild, fragrance-free cleanser that won’t strip your skin of essential moisture. Look for products labeled as “gentle” or “for sensitive skin,” and avoid harsh scrubs or exfoliants that can exacerbate dryness and irritation. - Moisturize Generously
Hydration is essential while taking oral retinoids. Choose a moisturizer that’s rich yet non-comedogenic (won’t clog pores). Ingredients like ceramides and hyaluronic acid help reinforce the skin barrier, lock in moisture, and reduce flakiness. - Use Sunscreen Religiously
Oral retinoids can increase photosensitivity, making your skin more vulnerable to sun damage. Apply a broad-spectrum sunscreen with an SPF of 30 or higher every day. Reapply every two hours if you’re spending extended time outdoors. - Limit Additional Actives
While ingredients like benzoyl peroxide, salicylic acid, and topical retinoids can be helpful in some acne routines, they may be too harsh in combination with oral retinoids. Use them only under professional guidance, or pause them if you notice excessive dryness or irritation. - Avoid Over-Exfoliation
Steer clear of rough physical scrubs and strong chemical exfoliants unless specifically recommended by your dermatologist. Over-exfoliating can weaken the skin barrier and lead to increased sensitivity. - Keep It Simple
Less is often more when your skin is in a reactive state. Stick to the basics—cleanse, moisturize, and protect with sunscreen. If you need additional targeted treatments (like spot treatments), introduce them gradually and watch for signs of irritation.
FAQ About Oral Retinoids
Is there a chance my acne will return?
Many patients enjoy long-term remission, though some might require maintenance treatments or additional courses to keep their skin clear.
Are blood tests necessary?
Yes. Isotretinoin is processed by your liver, and it can sometimes affect liver enzyme levels. In addition, it can alter your lipid profile by raising cholesterol or triglyceride levels. Regular monitoring through blood tests ensures that your liver is handling the medication well and that any changes in your lipid levels are caught early. This allows your doctor to adjust the treatment if needed, ensuring both safety and effectiveness.
Is there a difference between generic and brand-name isotretinoin?
In most cases, generic and brand-name isotretinoin are equally effective. Brand-name versions (like Accutane) might differ in inactive ingredients, but the active component remains the same. Always follow your doctor’s advice on which version to use.
Can oral retinoids cause hair thinning or hair loss?
Mild hair thinning can occur in some cases, although it’s not the most common side effect. This effect often resolves once you’ve stopped treatment, but if you notice significant changes in your hair, let your healthcare provider know.
Are there dietary restrictions while on oral retinoids?
There aren’t major dietary restrictions, but because isotretinoin can affect cholesterol and liver enzymes, it’s wise to follow a balanced diet and avoid excessive alcohol consumption. Regular blood tests will help monitor any changes.
