Fine Lines & Wrinkles – 8 Common Causes Treatments & Prevention

Posted by Dr Theva in Anti-Aging.

One day, you look in the mirror and realise something is different. Those subtle laugh lines around your eyes aren’t so subtle anymore, and you look much older than the youthful, vibrant person you feel like. Wrinkles are a fact of life, but you may have noticed that not everyone shows signs of ageing at the same rate. That’s because many different conditions contribute to the formation of fine lines and wrinkles. Some of them you can control, and some you cannot.

Loss of collagen and the changes to the skin from photodamage starts as early as your 20s. Whether you’re just beginning to see signs of ageing or are already active with treatments, here’s everything you need to know about the common causes of fine lines and wrinkles to give your skin an advantage over the effects of time.

What are fine lines?

Fine lines are shallow, superficial lines close to the skin’s surface. These are the less severe wrinkles that usually involve textural changes of the skin’s surface. These fine lines are separate lines at first but will gradually group together and often appear around the mouth or eyes where the skin creases when you smile, laugh, frown or squint.

The weakening of the skin that creates fine lines is caused by the diminishing of collagen, elastin and hyaluronic acid that makes the skin elastic and supple. These types of wrinkles are best treated by dermal fillers, many of which restores hyaluronic acid. Hyaluronic acid attracts moisture to the area and locks it into the skin.

With time, fine lines may turn into mimetic wrinkles as the skin loses elasticity and firmness.  

What are wrinkles?

Mimetic wrinkles on the other hand are deep-set creases in the skin. Unlike fine lines, wrinkles are more severe and have visible dermal creasing. Major causes include natural ageing and repeated dramatic facial expressions.

They usually first appear on the forehead and are mainly treated with anti-wrinkle injections. Expression lines are generated by constant stress on the skin caused by facial muscles movements. By relaxing the action of these muscles, anti-wrinkle injections make the wrinkles appear smoother and the face look more relaxed.

What causes fine lines & wrinkles?


With time, your skin starts to age, and wrinkles are a natural part of the ageing process. They typically begin to appear once you reach your mid-twenties to early thirties. As we age, collagen and elastin in the skin begin to break down, causing the skin to lose firmness and elasticity. Additionally, cell metabolism slows as you age, so the skin doesn’t regenerate as quickly.

Sun exposure

Sun exposure is the most common cause of skin damage and wrinkling. In fact, roughly 80% of facial skin ageing is due to sun damage from ultraviolet (UV) rays. Guarding against the sun’s UVA and UVB rays is fundamental to skin health, as both are responsible for long-term damage, including wrinkles. 

Exposure to ultraviolet (UV) radiation affects the layers of the skin in different ways. Overexposure breaks down the skin’s underlying structure by damaging collagen fibres in the dermis and we all know how important collagen is for the skin’s elasticity and firmness. In addition to fine lines and wrinkles, UV damage causes brown spots and pigment irregularity, as well as broken capillaries and red blotches. All these changes make the skin look older.


Nicotine in cigarettes deprive skin cells of oxygen and constricts the blood vessels that feed nutrients, such as vitamin A, to the skin cells. Smoking damages collagen and elastin, the fibres that give skin its strength and elasticity. As these fibres are destroyed, the skin begins to sag and droop. Smokers tend to experience premature wrinkles and their skin often appears dramatically older than that of people of the same age who do not smoke.


Pollution is one of the main sources of damage to the skin. As smog, dirt and dust float through the air, they often come in contact with the sun’s ultraviolet rays. This creates free radicals, highly charged oxygen molecules that are harmful to the skin and the body. Free radicals attack cells and damage DNA, and both air and water pollution can strip skin of moisture, causing discolouration, fine lines and wrinkles

Hormonal changes

During different stages of menopause, biological factors cause a healthy woman’s skin to age more rapidly than at any other stage of her life. Reduced levels of estrogen lead to dramatic collagen loss, which accelerates skin ageing. This condition is referred to as estrogen-deficient skin and leads to several skin changes during menopause including dryness, dullness, more prominent wrinkles and a loss of plumpness.

Dehydrated skin

Water is an essential element in your body that needs to be replenished daily. When your water consumption is consistently low, cell damage occurs in your skin. Hydrated skin is better at keeping in moisture, fighting off pathogens, and remaining smooth and taught. Your skin can also become dehydrated from cold air, hot showers, and insufficient moisturisation. To avoid dehydrating your skin ensure that you consume enough water every day and invest in regular HydraFacial treatments to rehydrate your skin.


Genetics determine our ability to generate collagen and elastin (the parts of the skin that gives us elasticity and resistance to wrinkles). While genetics play a part in wrinkling, we should not resign ourselves to a fate of early wrinkles because of our ancestry. Start active prevention now and adopt lifestyle habits that will help prevent wrinkles.

Lifestyle choices

Anyone can adopt healthy lifestyle habits and avoid the sneaky bad habits that are a factor in wrinkle formation. These bad habits and lifestyle choices greatly affect our skin. Stress, poor diet, heavy alcohol consumption, lack of sleep and even what position you sleep are all lifestyle choices we can easily adjust to prevent wrinkles.
