Acne sufferers look younger for longer, new study confirms

Teenagers cursed with acne may have the last laugh over their peers with perfect skin, new research suggests.
Their cells have a built-in protection against ageing that is likely to make them look better in later life, a study has found.
Experts had already noted that signs of ageing such as wrinkles and thinning skin often appear much later in people who have experienced acne. Now, scientists believe they may have discovered why.
A study of white blood cells taken from individuals afflicted by spots showed they had longer protective caps on the ends of their chromosomes.
Called telomeres, the caps can be compared with the plastic tips that stop shoe laces becoming frayed. They help prevent the chromosomes, packages of DNA, deteriorating and fusing with their neighbours during cell division.
Telomeres shrink over time and are closely linked to biological ageing - people with long telomeres age more slowly than people with short ones.
The new research shows that acne sufferers tend to have significantly longer telomeres and may therefore be blessed with the gift of long-lasting youthfulness.
The study, published in the Journal of Investigative Dermatology, focused on 1,205 female twins, a quarter of whom reported having had acne.
