Skin 101
Before further exploring the actual causes of aging skin, let’s look at the different layers of skin. This will allow us to better understand the process of skin aging.
Skin covers the entire body and is the only organ of the human body that does so. Since the skin covers the whole body, it is one of the most accessible organs to view aging. Skin weighs, on average, 8 – 11 pounds.
The skin consists of three main parts: the epidermis, dermis, and subcutaneous fat.
Your Skin’s Shield: The Epidermis
- The Outermost Layer of Skin: Guards Against Irritants And Retaining Moisture.
- Provides a Barrier from Infections
- Makes New Skin Cells
- Older Skin Cells from the Bottom of the Epidermis Travel to the Top and Flake Off. Dead Skin Cells Are Replaced Every 2-3 Weeks.
- Regulates the Amount of Water Released. Crucial For Maintaining Non-Dry Skin.
- Melanocytes Make Melanin That Gives Skin its Color
The Middle Player: The Dermis
- Home To Sweat And Oil Glands *Sebaceous Glands, Affecting Skin Hydration And Youthfulness.
- Contains Nerve Endings For Sensation And Blood Vessels For Nourishment.
- Hair Roots
- Brings Blood to the Skin
- Held Together With Collagen. Vital For Skin Elasticity and Keeps The Dermis Resilient.
- Aging In The Layer Can Lead To The Development Of Fine Lines And Loss Of Elasticity.
The Fatty Layer: Subcutaneous Tissue
- Connects Skin To Muscle And Bone Providing A Cushioning Effect.
- Important For Thermal Insulation, Contributing To Temperature Regulation.
- The Thinning Of This Layer Manifests As Sagging Skin And Loss Of Volume.
- Adequate Hydration And A Balanced Diet Support Its Structure, Delaying Skin Aging.
Remember, factors like UV radiation, a lack of sun protection, cigarette smoke, and poor nutrition can speed up the natural aging process, impacting these layers and leading to premature skin aging. Adopting a healthy lifestyle and skin care routine can help maintain the integrity of your skin’s structure over time.

What Leads To Aging Skin?
As you age, your skin undergoes various changes due to both intrinsic and extrinsic factors. Intrinsic factors are those which are influenced by your genetics and natural aging process, while extrinsic factors are those which are influenced by external factors such as sun exposure, smoking, and environmental factors.
Natural Aging Process (Intrinsic)
Internal Age-Related Changes
Your skin naturally evolves with age. Collagen, which maintains skin firmness, and elastin, which preserves skin elasticity, diminish over time, leading to textural changes and the formation of fine lines and wrinkles.
Changes by the Decade:
- In your 20s, collagen production slows, and skin renewal begins to decline, causing dead skin cells to accumulate.
- Reaching your 30s, the thinning of the skin becomes noticeable as fat cells reduce in size.
- In your 40s, collagen production may cease, and signs of aging such as deeper wrinkles become more evident.
- By your 50s, reduced oil gland activity leads to dry skin, while menopause contributes to a loss of elasticity, further drying, and reduced tone due to lower estrogen levels.
Environmental Factors (Extrinsic)
Several factors from your environment can expedite the aging process of your skin, many of which are within your control to manage or mitigate.
Specific Accelerators Include:
Sun Exposure and UV Damage: UV radiation from sun exposure is the primary cause of premature skin aging. It leads to collagen breakdown and can cause visible changes like liver spots and fine lines. Sun protection, including the use of broad-spectrum sunscreens and wearing protective clothing such as long-sleeved shirts and wide-brimmed hats, can help prevent sun damage and photoaging.
Dietary Influence: A diet high in processed food and sugars can induce inflammation, affecting your skin’s structure. Conversely, a healthy diet rich in vitamin C, healthy fats, and antioxidants like those found in plenty of fruits and vegetables can support healthy skin.
According to the Mayo Clinic, research suggests that a diet high in processed or refined sugars or other carbohydrates and unhealthy fats promotes skin aging.
Lifestyle Factors:
Tobacco Use: Smoking is another factor that can contribute to aging skin. Nicotine found in tobacco restricts the flow of blood to the skin. This restriction causes the skin to become oxygen and nutrient-deprived, leading to a pruning effect. Besides nicotine’s damaging effects, other chemicals in tobacco are detrimental to the skin. Some of these chemicals trigger the destruction of collagen and elastin. This results in wrinkles and sagging skin.
There is also an increase in what is referred to as the smoker pucker’s lip lines. The pucker motion used by smokers to inhale over time leads to wrinkles/lines around the lips. Quitting smoking can help improve the appearance of your skin and prevent further damage.
Alcohol: Excessive alcohol consumption can dry out your skin and contribute to inflammation and puffiness. Hydration and moderation are key to maintaining a healthy skin tone.
Stress: Chronic stress triggers increased cortisol, which can accelerate the aging process. Techniques like yoga and meditation may counteract stress-related skin aging.
Environmental Pollutants: Free radicals from pollution and other environmental factors can cause oxidative stress, resulting in premature skin aging. Regular cleansing and antioxidants like vitamin C can bolster your skincare routine’s effectiveness against these external threats.
Inflammation: Inflammation can cause damage that stresses your skin cells and accelerates the aging process. Inflammation can also lead to a breakdown of the normal skin architecture leading to:
- Hyperpigmentation
- Loss of Collagen
- Loss in Hyaluronic Acid
- Thinning Skin
- Water Loss
It’s essential to understand that your choices can influence the rate at which your skin ages. Incorporating sun protection, maintaining a healthy lifestyle, and tailoring your skincare routine with active ingredients like retinoic acid, alpha hydroxy acids, and zinc oxide can help mitigate the effects of both intrinsic and extrinsic aging factors.
Common Signs of Aging Skin
As your skin matures, numerous transformations start to emerge. Collagen production, which acts as the skin’s support system, dwindles, often leading to visible signs like wrinkles and fine lines. These occur primarily around areas that are very expressive or constantly exposed to the sun, such as your face, neck, and hands. Besides these expression-related changes, your skin might lose its youthful coloration, developing uneven skin tone or liver spots – marks of pigmentation changes.
Dryness is another hallmark of aging; you might notice your skin becoming itchier and requiring more frequent moisturization to maintain smoothness. This dryness happens due to a decline in natural oils and a compromised barrier function, which keeps moisture locked in. Furthermore, your epidermis, or the surface of the skin, becomes thinner, making the skin more delicate and prone to bruising easily.
Sagging skin is indicative of the loss of elasticity, as critical components like collagen and elastin degrade over time. Aside from sagging, this process can cause skin lesions or benign skin tags, particularly in regions where skin friction is common.
Your pores may seem more prominent as the skin’s firmness wanes, and blood vessels may be more visible due to thinning skin. Additionally, age spots might become a concern as the cumulative effect of UV radiation from the sun and environmental factors – such as pollution or cigarette smoke – contribute to the skin aging process.
To maintain healthy skin, incorporating sun protection into your routine is crucial. This can range from applying products with zinc oxide or titanium dioxide, which ward off UV rays, to wearing protective clothing like long-sleeved shirts or a wide-brimmed hat. Free radicals produced by UV exposure and cigarette smoke can accelerate skin aging by causing oxidative stress, emphasizing the importance of a skin care routine with antioxidants like vitamin C.
As skin ages, it’s affected by a combination of natural and extrinsic factors. It’s important to realize that while aging skin is a natural part of life, lifestyle choices such as maintaining a healthy diet, staying hydrated, minimizing stress, and fostering a consistent skincare routine with active ingredients can all contribute to a healthier-looking complexion even in later life.
