Madam, thank you for contacting Practo. Since you are already taking isotretinoin (acutret), you have to continue it for at least 3 months. However, in your case, at 28 years age, you may need to start additional hormonal medicines or topical creams. Please share the photo so that we can grade your acne and give the treatment accordingly.
Next Steps
Share a photo of the acne from front, sides. If it is involving your body, then mention that. And finally, mention if there is any flare during your periods.
