When the sun is shining, the first thing to do is protect the skin from UV rays. While they're not the enemy, and actually provide a healthy dose of essential vitamin D, overexposure is a disaster that leads to burns, accelerated ageing and even skin cancer. Apply an SPF daily (make sure that yours protects from both UVA and UVB rays) and don't forget to apply it your neck and ears too; these areas are often forgotten but can still get burnt. Top it up regularly throughout the day and seek shade between midday and 3pm, when the sun is at its strongest. Help to undo any damage and dryness caused by excessive sun exposure with a nourishing face mask; look for soothing and hydrating ingredients such as aloe vera, calamine, honey and hyaluronic acid, which will help your skin to hang onto moisture.
