Dr Ejikeme understands that some people like the feel of a traditional moisturiser, so in that case she consistently recommends the Obagi Hydrate Facial Moisturiser (£40). "It's non-comedogenic and I've found that my patients who are very acne-prone can use it when their skin feels dry. For example, if you're very, very oily, you'll probably be using a retinol, which, in turn, will dry out the skin. This helps to soothe any of that dryness," she explains.
