Humphrey's Witch Hazel Toner (£20)
Dr. Engelman recommends the Humphrey's Witch Hazel Toner to keep skin balanced. "The brand makes excellent alcohol-free toners that are infused with botanicals, like rose and aloe, to further nourish the skin," she says.
It's also a great way to prep your skin before applying your creams and serums, ensuring it's truly clean.
