It is safe to undergo subcision, TCA Cross or RF microneedling while on low dose isotretinoin.
There is a published paper/guidelines by the American Society for Dermatologic Surgery in October 2017 that elucidated this.
The task force concluded that it is safe to undergo superficial chemical peels, nonablative lasers, including hair removal lasers and lights, vascular lasers, and nonablative fractional devices for patients currently or recently exposed to isotretinoin.
In fact, the paper further highlighted that there are potential benefits while on isotretinoin and undergoing scar treatments. These include earlier access to scar treatments for many patients who are at high risk for further acne scarring and thereby improving patient quality of life.
In my practice, I focus on both reducing acne and treatment of scars concurrently. This usually involves a detailed assessment and review of the underlying causes of the acne, and a customised treatment plan which can include a good skincare regime and balanced diet and lifestyle, as well as topical therapy, oral medications and procedures like lasers, RF needling, subcision, TCA cross and chemical peels to treat the different types of acne scars.
