Some people see these wrinkles as early as their 30s. However, there are certain persons who appear to be ageless. They might live into their late 50s with few, if any, wrinkles. It all comes down to genetics and lifestyle. No one can stop the aging process but they can certainly slow it down by taking care of themselves. The skin on your face grows throughout your life, even after you finish growing physically. It becomes thicker during your 20s and 30s, then loses much of its elasticity and begins to show signs of aging. By eating well, exercising regularly, and protecting your skin from the sun, you can delay the effects of aging and enjoy a lifetime of beautiful skin. Neck wrinkles begin to show up around 45 years old. They're mainly due to two factors: the first is the loss of muscle tone and the second is the weakening of the underlying bone structure. As we age, our body's ability to produce collagen decreases, which means it takes longer for your skin to recover from injuries or stress. When this happens repeatedly over time, it can lead to deep lines forming at the back of your neck. You can reduce the appearance of these neck lines by maintaining a strong core body of muscles that control movement in the chest, back, and neck.
