What is the best chemical peel for rosacea acne?

Thank you for your question. I suggest that you move forward and consult with a board certified facial plastic surgeon.
Best wishes,

A chemical peel for rosacea would not be my first choice for rosacea.  I would recommend using a pulse-dye laser, such as Candela's V-beam.  It may take more than one treatment, but you should receive a good result.

Dear Kasia1969,
A good peel for rosacea acne would be a Salycilic peel, make sure we are gentle not using too many layers. Multiple treatments would be necessary for protecting our skin from any further flare up. You will also want to minimize any flare ups by minimizing spicy foods, excessive heat exposure, sun, ect.
The exact customized treatment depends on the individual as well.
Best of luck with your treatments,
Dr. Mahajan
