Skin changes occur naturally when people age, and this leads to a wrinkled appearance. These changes are due to a variety of things, and there are many anti-aging products available that claim to slow down or reverse the process.

Sun Exposure

One of the biggest causes of wrinkles is overexposure to the sun. The ultraviolet rays (UV) cause a series of reactions in your body that eventually lead to wrinkles. Each time your skin is exposed to UV, free radicals are produced, which attack the cell membrane structures. UV exposure also decreases the antioxidants in the skin, which are important for the maintenance of skin tautness.


Smoking depresses the collagen production in the skin, which is a key component. This loss eventually leads to wrinkles.

Loss of Skin Proteins With Age

Your skin is made up of two proteins, collagen and elastin, that contribute to its elasticity and firmness. As you get older, elastin begins to degenerate and thin, causing numerous lines on the face. With age, your skin begins to lose about one percent of collagen each year, and sunlight increases this rate. Without collagen, the skin begins to wilt and sag, also contributing to the look of wrinkles. 

Common Anti-Wrinkle Treatments

Besides staying out of the sun and quitting (or not starting) smoking, there are a variety of products that claim to help fight the aging process. As part of their anti-aging regimen, many people are opting for different treatments that have anti-wrinkle properties. There are a number of available creams, including those containing retinoid, which help to decrease the look of not only wrinkles but fine lines as well.

Some choose a variety of aesthetic procedures that are known for removing layers of the skin, which can result in a more youthful appearance. These include:

  • Botox injections
  • Chemical peels and dermabrasion
  • Laser treatments using ablative and non-ablative lasers
  • Collagen-stimulating fillers

Some of these treatments are accompanied with unwanted side effects, so do some research before deciding which one is best for you.
