Stock up on proteins - New York dermatologists say there is no substitute for omega oils and collagen-boosting amino acids from eggs, oily fish, nuts.

Cut out sugary foods - In a process called glycation, sugar from the bloodstream sticks to collagen, causing it to harden, break and create lines. Dermatologists recommendes a face-saving GI Diet to keep your weight and glycaemic levels down, without risking good dietary habits.

Drink wisely - Remember your skin is made up of up to 70 per cent water, and staying hydrates is vital to help enzymes which enable collagen production. You should therefore limit your alkohol intake, which dehydrates you. Drink antioxydant - rich green tea with lemon instead.
