Why do we have fine lines and wrinkles as we age?

  • Although wrinkles and fine lines are inevitable signs of aging, we have a measure of control over when they will appear 
  • We can mitigate skin aging with lifestyle choices and skin care routines. 
  • Oral collagen supplements can improve skin collagen density, elasticity, and moisture.


The onset of wrinkles and fine lines on the face is a telltale symptom of aging. Wrinkles appear as ridges, folds, and creases on the skin. While we all yearn to have smooth and supple skin forever, wrinkles are an unavoidable consequence of the aging process. 

Although you can't stop time from passing, you have a measure of control over how it affects your skin. You can do more for your skin if you have a firm grasp of why we have wrinkles and fine lines as we age.





The Skin's Role in Body Function


As the largest organ, the skin plays an essential role in maintaining health. The skin serves several vital purposes as a protective layer between the body and its external environment. It prevents dehydration, regulates core body temperature, and shields the body from harmful bacteria and chemicals. In addition, the skin is a sensory organ vital for vitamin D production.

The skin goes through a series of changes as we age. For example, its resilience decreases as it becomes thinner and drier, making it vulnerable to wrinkles. A variety of factors contribute to these alterations in skin texture and tone. Let's begin with a discussion of two molecules that influence the development of wrinkles and other signs of aging – collagen, and elastin.



Anatomy of human skin and how collagen can help with it's components





Collagen is an essential protein that gives the skin its firmness and elasticity, giving it a more supple youthful appearance. Collagen is a crucial component of skin. There is more collagen than any other type of protein in the human body. Collagen makes up roughly 33% of the protein in the human body and 75% of the skin's dry weight. 

As you become older, collagen begins to break down. Our collagen reserves deplete (with about a one percent reduction in production annually), and our collagen fibers thin and weaken. How rapidly this happens depends on your genetic makeup. As Collagen degrades, it becomes more difficult for the body to manufacture new ones. One of the ways to boost collagen production is by taking collagen supplements.  




Elastin is a protein that provides skin and other tissues and organs with their elasticity. Elastin is especially elastic, helping the skin and other tissues regain their original form following expansion or contraction. Its function resembles how a rubber band can stretch and shrink or recoil. 

Elastin is, together with collagen, an essential structural protein responsible for giving skin its supple youthful texture. Conversely, reduced levels of these proteins in the skin cause wrinkles, fine lines, and other indications of skin aging.

According to the Cleveland Clinic, you can help your body produce elastin by eating a well-balanced diet, including greens, citrus fruits, fish, berries, and nuts. Exercise, establishing a proper skincare routine, quitting smoking, and wearing sunscreen will also help maintain elastin levels.

Causes of skin aging


The biological process of skin aging is intricate. Some of the causes of wrinkles are under your control, while others are not. These are termed intrinsic and extrinsic aging. 


Intrinsic aging 


Intrinsic aging refers to the unavoidable effects of time and age on a person's body, regardless of lifestyle or other environmental factors. For example, the onset of wrinkles due to aging is a natural part of aging.

The harmful effects of free radicals and the body's incapacity to properly heal their damage play a role in intrinsic aging. Intrinsic factors include genetics, age, gender, ethnicity, and life stages. These elements are beyond our control.

The first signs of intrinsic aging often appear in the mid-20s but may not become apparent for decades. At this time, collagen production in the skin starts decreasing by roughly 1% annually. Gradually, sweat and oil glands function less effectively, and elastin production decreases. Also, the rate at which new skin cells replace the old ones slows.

As a result of these changes, the skin becomes less elastic, making it more challenging to recover its normal shape. When this happens, fine lines and wrinkles develop around the outer corners of the eyes(crow's feet), the mouth, or the forehead. By age 50 and beyond, the wrinkles become more prominent.


Extrinsic Aging 


These lifestyle and environmental factors affect your skin's health and look. Up to 85 percent of visual indicators of skin aging are directly attributable to external factors. The best thing about extrinsic aging is that they are mostly under your control. Among the external causes of skin aging are:


Exposure to sunlight 


Prolonged exposure to UV radiation compromises the integrity of the skin. It alters the DNA structure of skin cells in many ways. UV rays destroy the skin's collagen and elastin fibers. This degradation makes the skin lose its elasticity and become thinner. Wrinkles begin to form as the skin starts to sag.

In addition to wrinkles and fine lines, a lifetime of sun exposure increases the appearance of age spots and the risk of skin cancer. Exposure to ultraviolet (UV) light can occur through sunbathing, tanning beds, and outdoor activities. 




Smoking speeds up the skin's natural aging process, resulting in premature wrinkles. This is due to smoking's effect on collagen production.Research shows that smoking inhibits the body's ability to produce new collagen. Therefore, wrinkles appear when collagen production slows down.

Similar to how smoking can reduce blood flow to the heart or brain, it can also damage the capillaries that supply oxygen to the skin. Wrinkles and sagging skin are more likely to appear if there isn't enough oxygen.

Also, the heat from the cigarettes and the repetitive motion of the facial muscles (pursing the lips and squinting) while smoking accelerates the appearance of wrinkles. 


Alcohol consumption 


Drinking alcohol regularly is one of the most significant lifestyle factors associated with rapid skin aging. Alcohol dehydrates the skin by stripping it of essential oils, moisture, and nutrients. In addition, excessive alcohol consumption can dry up the skin and destroy its elasticity, all of which contribute to the premature aging of the skin.




Air and water pollution are particularly harmful to our respiratory and immune systems. Still, they also have an effect on the skin. Pollutants such as sulfur dioxide and particulate matter contribute to free radical production and oxidative stress. These deteriorate collagen and leave behind visible signs of aging, including wrinkles and a loss of firmness.


Unhealthy diet


However, a diet high in fast and sugary foods also has adverse effects. Evidence from studies suggests that a diet heavy in sugar and processed carbs can cause skin damage over time.

The effects of a diet high in processed foods and sugars extend far beyond accumulating extra pounds. For example, a study shows that a diet high in sugar and processed carbs might harm your skin in the long run.

Treatment for wrinkles and fine lines 


Although treatment is not required for wrinkles, it is an alternative if you want to look better. Treatment for wrinkles encompasses a wide variety of methods for reducing the visibility of lines and creases on the skin. Examples include dermal fillers, botox, facelifts, chemical peels, dermabrasion, laser Resurfacing, etc. 

Any wrinkle treatment can have benefits, adverse effects, or unwanted consequences. Each wrinkle treatment has its pros and cons, but in general, they include the following:




  • Treatment helps to smoothen the skin and lessen the visibility of wrinkles.
  • Boost in self-confidence increases productivity 
  • Non-invasive procedures might yield immediately visible improvements.
  • Some treatment options don't hurt.




    • Face shots typically cause provisional paralysis, i.e., difficulty moving the facial muscles
    • An allergic reaction could make the skin look much worse than it initially did.
    • Bruising, swelling, and scarring may occur.
    • Infection at the surgical site
    • Not all treatments provide the most natural-looking result.
    • Some treatment choices are invasive and expensive.

    How to mitigate skin damage


    Even though wrinkles and fine lines inevitably result from aging, you have some control over how quickly this happens. Making habitual healthy lifestyle choices is the key to effective skin care.


    Limit Sun Exposure


    Keeping your skin out of the sun is crucial to maintaining its health. Always apply sunscreen with a broad-spectrum SPF of 30 and above every two hours after swimming or heavy perspiration. Cover up when outdoors; wear wide-brimmed hats and protective sunglasses to shield your skin from sun rays. If possible, stay indoors from 10 a.m. to 4 p.m. when the sun's rays peak. 

    In addition, the American Academy of Dermatology (AAD) also warns that UV photons from tanning beds are as damaging as those from sunlight. Safety precautions from UV radiation are valid for everyone, including individuals with darker skin tones.


    Avoid smoking 


    One of the healthiest choices you can make is to abstain from smoking. You'll delay the onset of wrinkles while reducing your risk of developing numerous types of cancer and cardiovascular disease.

    Also, the best thing you can do for your skin if you are a smoker is to give up the habit. If you need help quitting smoking, go to your doctor. 


    Get adequate sleep


    While we sleep, our skin goes into a repair mode, thickening, producing more collagen, and increasing blood flow to speed up cell turnover. That's why a good night's rest can do wonders for your complexion, making it look younger and more luminous. The National Sleep Foundation suggests adults get between seven and nine hours of shut-eye nightly.


    Eat a healthy diet


    A more youthful appearance is achievable through diet. To feel and look your best, eating healthily is essential. Like the rest of the body, the skin benefits from getting enough of the right nutrients.

    Antioxidants, biotin, and vitamins C and E - natural collagen boosters, are some of the best nutrients you can eat for your skin. Antioxidants protect collagen in the skin from free radicals that can break it down, leading to wrinkles.

    To keep wrinkles at bay, consume a diet rich in fruits, healthy grains, and lean proteins. On the other hand, you should stay away from high-fat and high-sugar diets because they can break down collagen.


    Take collagen supplements 


    Wrinkle and fine line reduction are among the many skin health benefits of collagen supplements. One possible mechanism by which these supplements operate is by encouraging natural collagen production. Research shows oral collagen supplements improve skin collagen density, elasticity, and moisture. 

    The highest quality collagen supplements contain pure, premium collagen. For example,  JOOSH's Hydrolyzed Collagen Peptides is a premium collagen supplement. Because the collagen has been hydrolyzed, it can be absorbed more quickly and efficiently to help reduce wrinkles and smoothen out fine lines.



    The differences between extrinsic and intrinsic aging and how collagen can mitigate skin aging





    Indeed, we have no control over time. As a result, our skin's capacity to renew and recover from damage is impaired as we age. However, we can mitigate (or even reverse) signs of aging of the skin with the right combination of lifestyle choices and skin care routines. These actions promote skin regeneration and safeguard it against further damage.

    Some lifestyle habits to help achieve healthy skin aging include protection from sunlight, a nutritious diet, adequate sleep, collagen supplements, and avoiding pollutants like smoking. Undoubtedly, taking care of your skin health daily will reward you with a radiant, youthful glow for years to come.
