Hello and thank you for your question. There is no contraindication for using a Tretinoin and getting micro-needling done. If you skin is broken out and swollen I would suggest you speak to your dermatologist to get you on a better skin care and acne regimen. It is better to treat skin that is not broken out or irritated since we are creating micro injuries using the micro pen. Micro-needling is an excellent treatment to improve texture and overall appearance of the skin, it is typically our go to treatment for patients who have struggled with acne. Hope this helps, regards Dr.S.
Acne Scarring -- Requires a Combination of Fractional Laser Resurfacing, Fillers Like Bellafill, Subcision and Eclipse Micropen
Microneedling can be done while on topical creams and is best in combination with other lasers. Best, Dr. Emer.
