As your body’s largest organ, skin requires appropriate and consistent care. “Healthy skin has radiance, or a glow, good elasticity and minimal signs of photo-aging, and is well hydrated,” says Dr. Julie Karen. But since it’s your body’s armour, it’s constantly being bombarded by harmful elements. “Sun exposure, diet, pollution, smoking, et cetera, all result in the appearance of lines, pigmentation and loss of elasticity,” says Dr. Jean-Louis Sebagh. Maintain the health of your skin by choosing the right skincare products from an early age. “It is very important, from the teenage years onward, that good skincare and cosmeceutical products with active ingredients are used,” says Sebagh. Wearing SPF 30 daily, all year round, is step number one. Then it’s important to feed skin with the right ingredients to make sure it has what it needs. Maintain the barrier function with moisturizers that combine hydrating humectants (like hyaluronic acid, glycerine and other emollients), so that it’s resistant to things like redness and irritation. Proper hydration will help maximize your inner glow, as will fighting the effects of the elements with vitamins C and E and green-tea polyphenols, which have been shown to protect against UV-induced damage caused by free radicals. Exfoliation with chemical exfoliants like alpha-hydroxy acids will also help to keep skin tone uniform.
