When it comes to skin aging, there's not much we can do to completely stop the process. Signs of aging like wrinkles and spots are the results of the accumulation of defects in cells and intracellular structures. Experts have found that skin aging typically starts around age 25.

At what age does your face change most?

The biggest changes typically occur when people are in their 40s and 50s, but they can begin as early as the mid-30s and continue into old age. Even when your muscles are in top working order, they contribute to facial aging with repetitive motions that etch lines in your skin.

Which part of your body ages the most rapidly?

Yes, your head is growing old faster than the rest of your body. But you don't need to stress about it a lot as it is only so by nanoseconds -90 billionths of a second over 79 years, to be precise. In simple words, when you will reach 79, your head will be 90 billionths of a second older than other parts of your body.
