Fake tans do not provide any sun protection. Use tinted sunscreen with a high SPF instead. “These days you can get pigmented ones or tinted ones which are more cosmetically acceptable,” says Dr Mayou. Also keep in mind that certain ingredients, like citric acid found in citrus fruits, can dissolve sunscreen. To avoid this issue, choose a mineral sunscreen with zinc oxide or titanium dioxide as the active ingredient, as they are resistant to this chemical reaction.
