Anti-wrinkle treatments are some of the most in-demand treatments in existence. Consumers are constantly on the search for the ‘Holy Grail’ of anti-wrinkle treatments. So what actually are wrinkles, and what really works to help improve their appearance? 

What are wrinkles?

Wrinkles, also known as rhytides, are lines and creases that form in the skin.

What causes wrinkles?

Wrinkles are a natural part of the ageing process, as our skin dries, becomes thinner, and the volume of fat, collagen, and elastin decreases. Genetics have some influence on how wrinkled your skin becomes. In addition, factors such as sun exposure and smoking contribute to wrinkle formation, as they reduce the collagen and elastin in the skin. Repeated facial expressions, such as frowning or smiling, can lead to wrinkle formation where the muscles used for these expressions contract. Examples of these wrinkles include the frown line in between the eyebrows from frowning, and crow’s feet, wrinkles on the outer side of the eyes, from smiling. 

What types of wrinkles are there?

There are two main types of wrinkles: dynamic wrinkles and static wrinkles. Dynamic wrinkles are most prominent when muscles contract, and are due to facial expressions such as frowning or smiling. Static wrinkles are present at rest, and are more related to ageing and sun damage

How can I prevent wrinkles?

Sun protection, avoiding smoking, and moisturising the skin are great basic steps to help prevent or reduce wrinkle formation. Muscle relaxants such as botulinum toxin can help prevent the development of dynamic wrinkles. 

How can wrinkles be treated? 

Dynamic wrinkles are best treated with muscle relaxants, such as botulinum toxin. Static wrinkles can be improved with topical retinoids, alpha and beta hydroxy acids, vitamin C, niacinamide, chemical peels, radiofrequency, lasers, dermal fillers and ultrasound. Sometimes, surgery is recommended.
