Age related decreases in the volume of fat cells in the subcutaneous layer may be caused by telomere shortening, and can lead to more noticeable wrinkles and sagging; Sunlight may contribute to this degradation of the dermis; Sunlight does not appear to shorten telomeres

Mice engineered to lack the enzyme, called telomerase, become prematurely decrepit. But they bounced back to health when the enzyme was replaced. The finding, published online today in Nature, hints that some disorders characterized by early ageing could be treated by boosting telomerase activity.
