Dry skin is most likely to show signs of aging first due to its inherent lack of moisture and natural oils. The skin’s outer layer, known as the stratum corneum, is vital for maintaining hydration. When this layer is compromised, as is often the case with dry skin, it leads to increased transepidermal water loss. As a result, the skin can become less elastic, leading to a more pronounced appearance of fine lines and wrinkles.

Additionally, dry skin tends to lack the lipids necessary to create a protective barrier, making it more susceptible to environmental factors that can exacerbate aging, such as UV rays and pollution. These elements can accelerate the breakdown of collagen and elastin, essential proteins that maintain skin's youthfulness and firmness.

In contrast, oily, combination, and normal skin types generally retain moisture better and often have more active sebaceous glands, which can help delay the onset of visible aging signs. This is why people with dry skin might notice fine lines and other aging symptoms earlier in life compared to those with other skin types.
