What should I put on my face after undergoing Fluorouracil treatment? Given the potential for irritation and sensitivity following such a therapeutic regimen, it becomes crucial to identify appropriate post-treatment skincare measures to facilitate healing. Is it advisable to employ gentle, hydrating formulations to restore the skin barrier? Should one consider products that are specifically designed to alleviate inflammation or redness, particularly since Fluorouracil may leave the skin looking aggravated? Might there be merit in using non-comedogenic moisturizers or soothing balms infused with ingredients like aloe vera or calendula? Additionally, how important is it to avoid active ingredients commonly known for their harshness, such as retinoids or acids, at this stage? Could SPF protection be non-negotiable, even when the skin feels particularly vulnerable? Ultimately, what constitutes an optimal approach to nurturing the skin back to health in a delicate and conscientious manner?
