Medications that help at this stage include:
- Prescription tretinoin products like Retin-A, Retin-A Micro, and Avita reverse the "stickiness" of the skin cells allowing them to slough normally.
- Prescription oral antibiotics also kill the P. acnes bacteria and are often used to calm down the infection with cystic acne.
- Isotretinoin (Accutane) may be prescribed to treat moderate to severe cystic acne. Accutane does have serious side effects and needs to be monitored closely if it is used.
