The Science of Aging: Understanding How Our Skin Changes Over Time

Aging is a natural part of life, but understanding the science behind it can help you make informed decisions about how to care for your skin. At Lisa Topham, RN in Wilton, CT, we focus on evidence-based treatments that support healthy aging, but the foundation starts with understanding why and how our skin changes over time.


What Happens to Skin as We Age

Our skin is made up of multiple layers, each playing a crucial role in maintaining its structure, elasticity, and appearance. The outer layer, the epidermis, protects against environmental damage, while the dermis contains collagen, elastin, and other proteins that provide support and firmness. As we age, several key processes contribute to visible changes in the skin:


  • Collagen and Elastin Decline: Collagen gives skin its strength, while elastin allows it to snap back. Beginning in our mid-20s, collagen production decreases by about 1% per year, leading to thinner, less resilient skin. Elastin fibers also lose elasticity, causing sagging and the formation of fine lines.

  • Decreased Cell Turnover: Skin cell regeneration slows with age, which can result in dullness, uneven texture, and slower healing after damage.

  • Fat and Volume Loss: Subcutaneous fat decreases over time, contributing to hollowed cheeks, under-eye circles, and deeper facial folds.

  • Reduced Hydration: The skin’s ability to retain moisture diminishes with age, leading to dryness and accentuation of wrinkles.

  • Environmental and Lifestyle Factors: Sun exposure, pollution, stress, smoking, and diet all accelerate aging by damaging DNA, breaking down collagen, and increasing inflammation.

The Role of Hormones in Aging

Hormones also play a significant role in how our skin ages. Changes in estrogen, testosterone, and other hormones can affect collagen production, oil secretion, and skin thickness. This is particularly noticeable during menopause, when decreased estrogen levels contribute to dryness, sagging, and loss of elasticity.


Supporting Healthy Aging

While aging is inevitable, there are ways to support skin health and slow the appearance of age-related changes. Maintaining a balanced lifestyle, protecting skin from UV damage, and using targeted skincare are foundational strategies. At Lisa Topham, RN, we complement these approaches with advanced treatments such as facials, regenerative serums, and non-invasive procedures that stimulate collagen, improve hydration, and restore youthful volume.


Why Understanding Aging Matters

By understanding the science of aging, you can make informed choices about preventative care and maintenance. Knowledge empowers you to adopt strategies that not only improve appearance but also enhance overall skin health and resilience.
