This article takes a deep dive into the fascinating world of dermatology and skincare, offering insight into how our skin changes over time. Through practical advice and strategies adapted to each decade of our existence, we will explore how to gracefully navigate this natural process, highlighting the essential gestures to preserve the vitality and radiance of our skin through the ages.

What is skin aging?

Skin aging is a natural and complex process influenced by a set of internal and external factors, which leads to progressive changes in the skin. This includes changes in the texture, color, and elasticity of the skin, leading to visible signs such as wrinkles, volume loss, and dryness. Here is an overview of the main aspects of skin aging:

Internal (Intrinsic) Factors

  • Genetics: Genetics play a crucial role in the skin aging process, determining how and how quickly our skin ages.
  • Hormones: Hormonal changes, particularly during menopause, can affect the skin's elasticity and hydration.
  • Cellular metabolism: With age, the repair and renewal processes of skin cells slow down, affecting its appearance and ability to regenerate.

External Factors (Extrinsic)

  • Sun Exposure (Photo-aging): UV rays accelerate skin aging by damaging the DNA of skin cells, leading to wrinkles, loss of elasticity and pigmentary changes.
  • Pollution: Environmental pollutants can cause oxidation and damage the skin, accelerating skin aging.
  • Tobacco and alcohol: Tobacco and alcohol consumption contribute to the deterioration of the skin, affecting its structure and appearance.
  • Diet and lifestyle: An unbalanced diet and a sedentary lifestyle can have a negative impact on skin health.

Biological Processes of Aging

Glowing Skin - Collagen
  • Decreased production of collagen and elastin: These proteins are essential for maintaining skin structure and elasticity. Their production decreases with age, leading to the formation of wrinkles and loss of firmness.
  • Slowed cell turnover: The life cycle of skin cells slows down, which can lead to duller, less smooth skin.
  • Breakdown of skin lipids: Lipids in the skin play a key role in maintaining hydration. Their reduction contributes to dryness and loss of integrity of the skin barrier.

Key differences in skin aging

Caucasian Skin

  • Proneness to photodamage: Caucasian skin is generally more susceptible to sun damage, leading to premature aging, deeper wrinkles, sun spots, and an increased risk of skin cancer.
  • Early appearance of signs of aging: Individuals with Caucasian skin may begin to notice signs of aging, such as wrinkles and age spots, earlier than those with other skin types.

African type skin

  • Natural sun protection: African-type skin contains more melanin, providing better protection against UV damage. This can contribute to visible aging later.
  • Fewer wrinkles but more laxity: African skin tends to show fewer wrinkles but may experience greater loss of elasticity and firmness with age.
  • Hyperpigmentation: Pigmentation issues, such as post-inflammatory hyperpigmentation, are more common and visible.

Asian Skin

  • Resistance to photoaging: Similar to African-type skin, Asian skin tends to be more resistant to photoaging, with signs of aging appearing later.
  • Pigmentation Issues: Pigmentation spots and uneven skin tone are major skin aging concerns in Asian populations.

Factors Contributing to Differences

  • Melanin: The type and amount of melanin in the skin influences its responsiveness to UV damage and aging processes.
  • Structure and Composition: Variations in skin structure, including dermis thickness, collagen density, and lipid composition, can affect the appearance of signs of aging.
  • Genetic and Environmental Factors: Genetic predispositions combined with environmental factors (such as sun exposure, diet, and lifestyle) play a role in skin aging.

These differences highlight the importance of personalized approaches in skin care and anti-aging treatments. Recognizing these variations can help develop more effective skincare strategies tailored to the specific needs of each skin type, to prevent and treat signs of aging appropriately.

How does skin aging occur over the course of a lifetime?

Skin aging is a progressive process that takes place throughout life, marked by different phases and characteristics depending on age. This process is influenced by a combination of genetic (intrinsic) and environmental (extrinsic) factors, such as sun exposure, pollution, diet, and smoking. Here is an overview of the evolution of skin aging over a lifetime:

Childhood and Adolescence

  • The skin is generally smooth, elastic, and rich in collagen.
  • Cellular regeneration is rapid, which allows for rapid and effective healing.
  • Sun damage is starting to accumulate, although it is not yet visible.

20 years

  • The skin is at its peak in terms of elasticity and cellular regeneration.
  • The first signs of extrinsic aging can appear in individuals with excessive exposure to the sun, in the form of fine lines or slight pigmentary changes.

30 years

  • Cellular turnover begins to slow down, leading to a decrease in skin luminosity and radiance.
  • The first expression lines may become visible, particularly around the eyes and mouth.
  • Collagen production decreases, leading to a gradual loss of elasticity.

40 years

  • The signs of aging become more evident, with deeper wrinkles, loss of volume and the appearance of age spots.
  • The skin may become drier and thinner, making blood vessels more visible.
  • The loss of firmness is noticeable, particularly around the contours of the face and neck.

50 years and over

Glowing Skin - Woman
  • Menopause can cause significant hormonal changes, increasing skin dryness and reduced elasticity.
  • Wrinkles are now well established, and the skin may show marked laxity.
  • Pigment spots and irregular textures are more pronounced.

How does the structure of the skin change?

The evolution of the skin's structure over the course of life is marked by several significant changes that affect its texture, elasticity, and general appearance. These changes are mainly due to altered levels of collagen, elastin, hydration, and the skin's ability to regenerate. Here is how these key elements evolve:


  • Youth: Skin contains an abundance of collagen, a structural protein that gives it firmness and elasticity.
  • From your 20s: Collagen production begins to decline by about 1% per year. This decline accelerates after menopause in women, leading to a significant loss of firmness and the appearance of wrinkles.


Glowing Skin - Elastin
  • Youth: Elastin allows the skin to regain its shape after being stretched or contracted.
  • With age: The quality and quantity of elastin decreases, which reduces skin elasticity and contributes to sagging and the formation of deep wrinkles.


  • Youth: Glycosaminoglycans (GAGs), notably hyaluronic acid, keep the skin hydrated by attracting and retaining water.
  • With age: The amount of hyaluronic acid and other GAGs decreases, making the skin drier, less plump, and more prone to wrinkles.

Cellular Regeneration

  • Youth: The skin regenerates quickly, which contributes to its ability to repair itself effectively after injuries or attacks.
  • As we age: The rate of cell turnover slows, leading to a buildup of dead cells on the skin's surface, which can cause a dull appearance and accentuate fine lines and wrinkles.

Other Structural Changes

  • Skin Barrier: The skin's barrier function weakens with age, increasing vulnerability to irritants, allergens, and infections.
  • Subcutaneous Fat Loss: The reduction in the fatty layer under the skin with age can lead to loss of volume and sagging, particularly visible on the face.
  • Microcirculation: Blood circulation in the layers of the skin can become less efficient with age, contributing to a reduction in nutrient and oxygen supply and a decrease in the skin's natural radiance.

By understanding how the skin's structure changes with age, it is possible to adopt targeted strategies to care for it and minimize the visible signs of aging.
