It's unavoidable - as you go through life, laughing, smiling, scowling, a series of facial wrinkles, or frown lines, will appear along the corners of your mouth, between or above your brows, or down from the corners of your mouth to your chin.
With both frown lines and facial wrinkles, there are two main factors as to how noticeable these will be. Your underlying bone structure, which you inherit from your family, and how much the sun has damaged your facial skin over time.
The number one factor in preventing and indeed treating frown lines is to reduce damage from the sun's UV rays. Using a sunscreen regularly will prevent any further damage to the elastic fibers that keep your skin smooth, thus halting new frown lines from forming and old ones from deepening.
Another important strategy is to wear sunglasses - why? Not only do sunglasses protect your eyes from UV radiation and look cool, but they also stop you scrunching up your eyes and forehead in the sun. If you are out in bright sunshine without a pair of shades, you accelerate the development of wrinkles on your forehead.
To help improve appearance of existing wrinkles, you should use a moisturizing cream or lotion that contains glycolic acid - this will help eradicate wrinkles that are not deep. Look for a moisturizer that contains 8 or 10 percent glycolic acid - this will loosen old cells on the skin's surface and swap them for fresher cells underneath, thus lessening or eradicating small wrinkles.
Prevention is no doubt better than cure. But if you have some damage you want to treat, then the most effective methods are creams containing Retinol, which reduces wrinkles by rejuvenating cells at the lower layers of skin, or Botox injections. However, Botox injections need to be repeated every few months, and can produce side effects such as headache, nausea, and face pain.
