I would recommend doing the peels and microneedling separate for several reasons. Microneedling opens up channels into the dermis of the skin. This can introduce the peel into a much deeper layer than what it is intended for and result in more pain and lower downtime. Also, although it is unlikely that a superficial peel such as the Vitalize peel can produce such scarring, any injury to the deep dermis can theoretically create scarring. I actually am a big fan of both modalities in rejuvenating the facial skin but you may be better off waiting at least two weeks to stagger the treatments so maximize the benefits of both. Hope this helps!Johnson C. Lee, MD Plastic Surgery
