Want to know which key ingredients could help skin maintain a little of its youthfulness, just like Twiggy's?
Popular examples include vitamins A, C, E and co-enzyme Q10. Help fight free radicals – chemicals formed in cells that contribute to ageing.
Alpha hydroxy acids (citric, glycolic, lactic, tartaric) often from fruit, which act as exfoliators. Help skin look smoother, more radiant.
Attract moisture to the skin. A popular one is hyaluronic acid, which can hold 1,000 times its weight in water. Others are glycerine and panthenol. They help combat the dryness that comes with ageing.
Proteins that aim to stimulate skin's production of collagen. Good for minimising the appearance of wrinkles.
Derived from vitamin A. Increase collagen and rate of skin rejuvenation for younger-looking skin. Best prescribed by a dermatologist.
