AND HOW DOES IT APPLY TO MY SKINCARE SHELF?

Your retinol obsession, it seems, is worth it. ‘When applied topically, vitamin A results in the proliferation of the top layer of the skin (known as skin cell turnover), promoting new cell growth,’ says Dr Shaaira Nasir, consultant dermatologist at sk:n clinics. ‘It also promotes the production of new collagen.’ She adds that, in your diet, vitamin A can help prevent cell damage, premature ageing and other skin diseases. A 2019 study by Brown University also found that those who ate higher levels of vitamin A were 17% less likely to get a common type of skin cancer years later. Inside and out, a thoroughly good shout.
