What serums do dermatologists recommend?

Could you elaborate on the types of serums that dermatologists typically recommend for skin care? Are there any specific ingredients or formulations that they tend to favor? Are there any skin conditions that may require the use of certain serums over others? Additionally, what are the potential benefits and drawbacks of using serums as part of a skincare routine? I'm curious to know more about the role that dermatologists play in guiding consumers towards the most effective and SAFE serum options for their individual skin needs.
