A wrinkle can be defined as dynamic or static due to its cause.
Dynamic wrinkles come with facial expressions. Skin is folded when the muscles underneath contract to make an expression. For example, squinting causes crow’s feet, frowning causes glabellar “frown” lines, and forehead “worry” lines. These dynamic wrinkles may develop into permanent static wrinkles if not treated in time.
Apart from developing dynamic wrinkles, UV radiations, lifestyle, and other aging factors may bring static wrinkles. Similar to loose or saggy skin, collagen loss changes the structure of the skin. The lack of support draws skin inwards and form grooves that are to be seen at all times.
Medications that contain retinoids, which are made from Vitamin A derivatives may reduce fine wrinkles. It works by prompting surface skin cells to turn over and stimulate collagen production. Typical side effects include but are not limited to dryness, tightness, peeling, and redness.
The Injection of botulinum toxin is one of the ways to reduce dynamic wrinkles. This injection helps to relieve and relax muscle contractions that bring dynamic wrinkles. However, as botulinum toxin will be absorbed and resolved by the human body with time, the result of the injection is not permanent. One may need to receive another injection in around 6 months to maintain the result.
There are different ways to improve static wrinkles. By injecting hyaluronic acid fillers that can support the skin structure, the results can last up to 12 months. By injecting Poly-L-Lactic acid, which can stimulate the growth of collagen, the results may last up to 2 years.
To prevent both dynamic and static wrinkles, one should have a healthy lifestyle and skincare routine.
