Is tretinoin the same as isotretinoin?

Tretinoin and isotretinoin are two extremely efficient prescription-grade medications used to treat acne. But which one is better?

The answer is not that simple. In spite of their similar names, isotretinoin and tretinoin are very different medications used to treat different severities and types of acne1.  

Tretinoin is a topical acne medications that comes as a cream or gel used to combat mild-to-moderate acne in the face as well as anti-aging2 3.

Isotretinoin is an oral medication used to treat severe acne in wide areas of the body that has not responded to other treatments4. However, it is important to note that this medication is highly controlled because of its teratogenic at all therapeutic doses5 and because the serious side effects it may cause6.

In this article, we will cover the differences and similarities between these two acne medications so you and your online dermatologist can choose what acne treatment is best for you. In addition tretinoin and isotretinoin, there are other retinoids used in the treatment of acne such as adapalene, trifarotene (Aklief), and tazarotene. These topical medications tend to be accompanied by oral antibiotics such Seysara and doxycycline for faster results.

Acne is a very common skin condition which affects more than 50 million Americans every year7. It occurs  when sebum and dead skin cells clog the pores, leading to outbreaks called “pimples or zits8” 

Acne outbreaks typically occur on the face but they can also appear on wide body areas such as the back, chest, and shoulders, hence the need for an oral medication such as isotretinoin.

Similarities between tretinoin and isotretinoin

  • Tretinoin and isotretinoin are vitamin A derivatives and first-generation retinoids9
  • Both products can be used to treat several skin conditions such as acne and other skin conditions

    Conclusion

    When deciding which acne medication is right for you, there are several factors to consider: tretinoin has fewer side effects, but isotretinoin is more effective at clearing stubborn acne.

    Before deciding on isotretinoin over tretinoin, or vice versa, it is important to do your research as there are many other medications that combat acne and have milder side-effects, such as adapalene, benzoyl peroxide, doxycycline or spironolactone. Speak to a medical professional if you have any questions and discover if one is right for your needs. Do not go on a prescription until knowing all the details as there are many negative side effects that can occur if used improperly.
