Laugh lines are the folds or wrinkles that run from the outer corners of the nose to the corners of the mouths. They are also called nasolabial folds. The formation of laugh lines is due to the natural processes of aging.

Why do laugh lines/ nasolabial folds form?

Did you know that our laugh lines are related to our cheeks? Although the formation of laugh lines or nasolabial folds occurs partially due to aging of the skin causing creases; aging in the cheeks also affects the severity of nasolabial folds. This has been explained in detail in Getting Cheeky: A Guide to Cheek Filler Injections.


As we age, the fat pads in the cheeks lose volume and support. The cheek fat pads descend downwards and deepens the folds around the cheeks i.e. nasolabial folds.

How can the risks of laugh line/ nasolabial filler complications be avoided?


Some of the techniques that your doctor can do to reduce the risk of blood vessel occlusion is to use a cannula or aspirate before injecting. Choosing an experienced doctor with a good grounding in facial anatomy and clinical acumen is also essential to ensuring best outcomes. Ultimately, everyone’s facial anatomy differs so taking precautions and the utmost care is of paramount importance to minimise risks.


The choice of nasolabial fillers also matters in avoiding complications of nasolabial fillers. There are also dermal fillers that are reversible. Hyaluronic acid dermal fillers can be dissolved with an antidote to reverse blood vessel occlusion.

What happens if I get too much laugh line/ nasolabial fillers?

The amount of correction of your laugh lines or nasolabial folds is determined by the amount of dermal fillers injected. Too little and the lines are under corrected; too much and you can look overfilled.


Having too much laugh line fillers may leave you looking like a pillow face or pug face. It’s important that your doctor discusses expectations, results and likely amount of dermal fillers required with you before proceeding with injections to avoid this unsightly outcome.

One of the things I do in my practice to avoid overfilling patients and still achieve very good results is with a Liquid Facelift or cheek fillers before finally filling the laugh lines. By first lifting the face, the severity of the laugh lines is reduced. This allows a smaller amount of nasolabial fillers required is smaller, so the results of laugh line correction are very natural- no overfilling of faces needed.
