Moreover, fine lines and wrinkles appear as a result of irregular dermal thickening and a reduction in the level of water held by the epidermis.
What Causes Facial Wrinkles?
There are several reasons why wrinkles form and become more prominent. These include:
As people age, skin cells divide more slowly and the dermis begins to thin. The dermis is a network of elastin and collagen fibers that provide support and elasticity. As it loosens and unfolds over time, depressions on the skin’s surface form. Aging skin is also less capable of retaining moisture, less efficient at secreting oil, and heals more slowly.
Facial Muscle Contractions
Small muscle contractions are known to cause forehead lines, frown lines, and crow’s feet. Smiling, frowning, squinting, and other repetitive facial expressions enhance these facial wrinkles. These expressions, combined with gravity, result in wrinkle formation over time.
Excessive sun exposure can cause photoaging or the skin’s premature aging. UV light causes collagen fibers to degrade, which then leads to the production of abnormal elastin.
When UV light causes damage to skin tissue, it produces an enzyme called metalloproteinase. This enzyme is responsible for the formation and reorganization of collagen. However, some healthy collagen fibers are disrupted during the process, culminating in solar elastosis or the disorderly formation of fibers.
Facial wrinkles form as the rebuilding process is repeated over and over again, becoming less efficient each time.
Smoking can speed up the natural aging process of your skin, causing facial wrinkles. This could be due to the effect of smoking on collagen production.
What Are the Treatments Options for Facial Wrinkles?
The most effective way to prevent wrinkles is to use a high SPF sunscreen (SPF 30 or more) on a daily basis. There are a variety of cosmetic creams and anti-aging products available to help conceal wrinkles and age-related changes.
In addition to topical applications, traditional methods of skin resurfacing include dermabrasion and chemical peels.
