So, how can we keep a youthful glow and perfect skin once we're reached the Big 40? First and foremost, protect your skin from the sun! Exposure to UV rays accelerates skin ageing and causes the appearance of liver spots. Opt for antioxidant creams with protective active ingredients to limit damage caused by UV rays and pollution. Swap your usual treatments for ones that help regenerate skin, in particular morning or night anti-ageing creams. Night creams, for example, are designed to help our skin regenerate, as it's whilst we sleep that our skin produces more new cells. Serums are anti-ageing superheros, as they contain twice the amount of active ingredients than a cream. You should also invest in an eye contour treatment to help drain away bags and signs of fatigue (the skin around our eyes is four times thinner than the rest of our face), alongside a lip contour cream to limit the appearance of lines that can give us a stern look. And last but not least, ditch the ciggies - it's never too late to give up the wicked weed!
