What Are the Causes of Skin Aging?

One of the most common signs of anti aging is fine lines and wrinkles. As we grow older, our skin loses its elasticity and becomes thinner and less oily, leaving it more vulnerable to the UV rays from the sun. During this time, our skin also produces less collagen and hyaluronic acid, two of the skin’s main components. As a result, wrinkles form and our skin becomes grey in color.


It is widely known that stress can have a detrimental effect on the skin. In fact, it has been linked to the aging process. According to studies, stress increases the production of the hormone cortisol and can affect the skin’s elasticity and texture. It also inhibits the function of insulin, a hormone that controls blood sugar levels. Moreover, it has been found that stress can result in the accumulation of fat and sugar in the body’s tissues.

Although wrinkles naturally develop as you age, stress causes your skin to break down the elastin and collagen in your skin. Moreover, it can cause wrinkles to form earlier than expected. Chronic high-stress levels also put the cells of your body under oxidative stress, which may lead to accelerated aging.


A long-term smoking habit can cause premature skin aging. One study of twins found that a pair of smokers had more severe wrinkles and sagging skin than their non-smoking twin. The researchers also discovered that the smoking twin’s skin was more susceptible to sun damage and non surgical facelift in Mumbai.

Smoking can also affect the skin’s hydration levels. It lowers the levels of collagen and elastin in skin tissue. This can lead to premature skin aging because the skin is not supplied with the proper amount of oxygen and nutrients. Furthermore, smokers’ skin is also drier than that of non-smokers.

In addition to damaging collagen and elastin, smoking also reduces the supply of vitamin A and C to skin cells. Vitamins A and C are essential for skin health and protection. Additionally, smoking causes deep lines around the eyes and mouth. This is because of the reduction of collagen and elastin, which contribute to skin elasticity.

UV radiation

Exposure to UV radiation and the sun’s rays is linked to skin aging, with UVB causing a decrease in skin elasticity and collagen production. Regular exposure to sunlight can damage skin cells and cause premature wrinkle formation. Exposure to UVB also increases the levels of collagenases, a type of enzyme that degrades collagen. Although these effects may not be enough to cause, they are considered to be a contributing factor to skin aging.

UV radiation is a known environmental mutagen, responsible for many skin diseases. It is emitted through sunlight and can damage DNA. It also causes mutagenesis in skin cells, causing direct and indirect DNA damage. Specifically, UVB can damage DNA by interacting with the double helix of DNA. In particular, the double bond in the 5-6 position of DNA is particularly vulnerable to UV damage. This broken double bond disrupts covalent interactions.

Infrared light

Recent studies have found that exposure to infrared light (IR) can cause premature skin aging. This type of light is converted into heat, and IR exposure causes a spike in skin temperature. The high temperature triggers inflammatory cells and damages DNA. Similarly, prolonged exposure to IR causes the skin’s structure to degrade and wrinkles to appear.

IR radiation is in the invisible portion of the electromagnetic spectrum, adjacent to the long wavelength of visible light, and extends to the microwave range. Several studies have demonstrated that IR radiation has a temperature-independent stimulatory effect on human fibroblasts. The effects of IR radiation have been studied in both wellness and cosmetic applications, but little is known about its effects on photo-aged facial skin lesions.

Free radicals

Free radicals are unstable molecules that attack other molecules in our bodies and cause them to break down. They attack proteins and biomolecules such as collagen strands. When collagen is damaged on multiple points, it loses its strength and elasticity. Free radicals can cause premature wrinkling of the skin. If you’re concerned about the aging process of your skin, then you’ll want to start taking steps to prevent the appearance of wrinkles.


Free radicals can be harmful because they destroy the structures and functions of our cells. They start the destruction process by taking an electron from a molecule. This process creates a domino effect and ruins the whole cell. This can lead to the development of fine lines and age spots. The loss of elasticity can also be a sign of aging.
