Isotretinoin is employed to treat severe acne but can have other possible benefits. Tretinoin, an isomer of it, is a medication for acne. [R]

Isotretinoin at 20°C, it is in a solid state with a melting point of around 172-177°C. [R]

The body synthesizes isotretinoin, also known as 13-cis-retinoic acid, from tretinoin (all-trans-retinoic acid), which is a retinol (vitamin A) derivative. Isomerization, which can occur in either a cis or trans conformation, is the process of converting a molecule into a new isomer. [R

How Isotretinoin Works?

As isotretinoin affects all of the key elements implicated in acne development, including cell-cycle progression, cellular differentiation, cell survival, and apoptosis, isotretinoin may possibly work with acne. It has anti-inflammatory qualities, lowers surface and ductal propionibacterium acnes (P. acnes), impacts conidiogenesis, and decreases sebum production. Because of its complex mode of action, it works well to possibly address severe nodular acne that has not responded to other acne medicines.

The sebaceous glands, which are in charge of creating oil in the skin, are diminished in size and activity by isotretinoin, which is its active ingredient. This may lessen how severe your acne is.

The scientific basis behind the benefits of Isotretinoin

The effectiveness and safety of isotretinoin have been explored. Isotretinoin has been thoroughly studied for its potential usefulness in treating a number of different diseases. The following list of recent tretinoin research topics includes:

Isotretinoin and Sebum Production

Forty-eight test subjects with acne were given oral 13-cis-retinoic acid in a double-blind dose-response trial. The results of the study showed that the test subjects’ acne significantly improved clinically, and this improvement was accompanied by a decline in the synthesis of free fatty acids (FFA) and sebum excretion rate (SER). The study also discovered a significant reduction in the number of microbes in the test subject’s acne-affected skin, with propionibacteria. It is crucial to remember that the decrease in microbial populations came after the decreases in sebum and FFA production. [R]

This implies that the drug’s impact on microorganisms is secondary to the alteration in sebum excretion, yet it is still a crucial element in the healing of acne. Overall, the study suggests that the primary mechanism by which 13-cis-retinoic acid improves acne is the reduction in sebum and FFA production, with the reduction in microorganisms being a secondary effect. The reduction in bacteria populations is still a key element in the healing of acne, though. [R]

Isotretinoin and Acne Vulgaris

In a trial, the effectiveness of low-dose isotretinoin (20 mg/d) in the treatment of mild acne was examined. 50 test subjects in total were enrolled, and 90.8% of those between the ages of 12 and 20 and 89.6% of those between the ages of 21 and 35 showed positive results. 5.2% and 7.4% of the two groups experienced treatment failure, respectively. According to the study, low dosages of isotretinoin are more affordable, less likely to cause severe adverse effects, and better in possibly addressing mild acne than higher doses. [R]

Isotretinoin and Folliculitis decalvans

The goal of one study was to identify the optimal oral isotretinoin monotherapy dose and duration for attaining remission in test individuals with folliculitis decalvans (FD). 39 male test participants received oral isotretinoin at doses of 0.1–1.02 mg/kg/day (10–90 mg/day) for a median time of 2.5 months (range: 1–8 months) in the retrospective case series investigation. After treatment, 82.0% of the test subjects showed improvement, and patients who received oral isotretinoin at a dose of 0.4 mg/kg/day for three months responded better, with 66% of them never experiencing a relapse. The study concludes that oral isotretinoin monotherapy is a promising alternative treatment for FD that warrants further investigation. [R]

Isotretinoin and Rosacea fulminans (pyoderma faciale)

A female test subject aged 3 had severe acne-like lesions on her face that did not get successful treatment despite receiving numerous treatments, such as corticosteroids and antibiotics. On the cheeks, the lesions appeared out of nowhere and spread quickly to other parts of the face. Bacterial cultures came back negative, and routine laboratory testing was normal. Erythromycin, prednisolone, fluocinolone acetonide cream, and warm compresses were used in the test subject’s initial treatment, which led to a moderate improvement. The skin renewed significantly after 4 weeks and completely vanished lesions after 8 weeks after isotretinoin was supplied at a dose of 10 mg daily. The test subject received isotretinoin treatment for a total of 24 weeks, and during the year of follow-up, there was no relapse. [R]


Despite Isotretinoin significant impact in addressing severe acne, it is important to know that it is also a teratogen, which means that if used while pregnant, it can lead to birth problems in developing fetuses. According to research, test participants exposed to the drug during pregnancy run a considerable risk of congenital abnormalities, with a risk of between 20 and 35 percent. [R]

Additionally, studies have discovered that isotretinoin prenatal exposure may also cause neurocognitive impairment in test subjects, with approximately 30–60% of test subjects exposed to isotretinoin prenatally displaying some form of cognitive impairment. [R]

Due to these dangers, isotretinoin is only given to female test subjects who have no chance of getting pregnant while taking the drug, according to strict regulations. Due to the significant risk of birth defects, isotretinoin exposure can result in the termination of pregnancies. [R]


Undifferentiated brain cells can grow into a solid pediatric tumor known as a neuroblastoma (NB). Despite recent advancements in disease care and therapy, it still ranks among the leading causes of childhood cancer mortality, necessitating the development of innovative therapeutic agents and regimens. Retinoic acid (RA), a derivative of vitamin A, is a powerful compound that can encourage differentiation in NB cells. The NB therapy uses its isoform, 13-cis RA or isotretinoin, albeit its effectiveness is limited to preventing the advancement of minimum residual illness. [R] Isotretinoin (13-cis-retinoic acid; 13-cisRA) has been shown to significantly improve survival for children with high-risk neuroblastoma. [R]

Mood Changes

When taking isotretinoin for acne treatment, test subjects who are puberty-aged frequently experience mood swings and depression. Isotretinoin has been linked to depression in a recent controlled case cross-over research, pointing to a rare idiosyncratic reaction in some young, vulnerable test patients. The study found that acne patients who took oral isotretinoin had a relative risk for depression of 2.68 (95% CI = 1.03 to 3.89). This is the first controlled study to identify an isotretinoin-depression link with statistical significance. [R]

Isotretinoin and Androgen Production

Depending on the test subject’s gender, isotretinoin has been discovered to have distinct effects on precursor androgens. Isotretinoin has been observed to increase free testosterone, a form of precursor androgen, in female test subjects. It has no appreciable effects on other precursor androgens, either. The serum levels of DHT and 3 alpha-diol G in female test participants, as well as those of 3 alpha-diol G in male test subjects, were observed to be depressed by isotretinoin, in contrast. These decreases in precursor androgens are assumed to be the result, not the cause, of the shrinking sebaceous glands. The size of the observed declines might be a reflection of the quantity of tissue-derived androgens that sebaceous glands typically add to the circulating pool. This shows that isotretinoin medication has a secondary effect on the decrease in precursor androgens rather than having an immediate impact on the body’s ability to produce androgens. [R]

Overall, isotretinoin’s effects on precursor androgens are complicated and gender-specific. Isotretinoin appears to lower the levels of other precursor androgens in both male and female test participants, even if it may increase free testosterone in female test subjects. [R]
