Thin lines are generally develop at 30s and become more distinct at 40s. Alongside common forehead lines, frown lines, crow’s feet, bunny lines and nasolabial folds, other thin and deep lines may also cause discomfort.
There are 4 main reasons of thin and deep lines:
UV exposure- Ultraviolet radiation speeds up aging process and is the major cause of early wrinkling. UV light decomposes your connective tissue – collagen and elastin fibers – within the deeper layers of your skin and leads to wrinkles.
Genetic aging- Skin aging is an inevitable and natural process. With natural aging process, your skin produces less collagen and elastin protein as the time passes. This makes your skin thinner and less resistant to damage.
Repeated moves- It’s believed that contraction of facial muscles at the forehead, between brows (frown lines) and crow’s feet, takes part in wrinkle development. Smiling, frowning, squinting the eyes and other habitual facial expressions make these wrinkles to become more distinct. In time, these expressions contribute to the formation of these wrinkles.
Environmental factors- Smoking, exposure to pollution and high stress levels may contribute to the formation of lines and wrinkles. A healthy skin continuously renews itself and produces new collagens, it has been found out that smoking causes a significant reduction in new collagen production. Reduced collagen causes wrinkles to develop. Pollution causes free radical damage on the skin and this leads to skin aging and cellular damage and contribute to the wrinkle formation. Stress may cause wrinkle formation because high amounts of cortisol stress hormone, may decompose skin’s collagen and elastin. This leads to a loss of elasticity which may contribute to the wrinkle formation. Stress also may cause your brows to be frowned again and again and this may also contribute to the wrinkle formation.
Different treatments are be applied for thin and deep lines according to their places on the skin and characteristics .
