Skincare is ultimately personal. This isn’t a takedown of vitamin C. However, there are some dermatologists who don’t love it. Consultant dermatologist Dr. Anjali Mahto has previously said, “I’m not regular about using a vitamin C in my own skincare routine, and personally, I could take it or leave it.” Here’s why: “I don’t like products being layered on my patients’ skin, either,” Dr. Mahto explained. “The more variables I put into my treatment plan, the more likely it is that you will get peeling, irritation, and sensitivity.” Instead of vitamin C, Dr. Mahto is more likely to recommend azelaic acid, which also helps with pigmentation and evening out skin tone.
