Yes, dermal filler can – depending on the lines – fill out, plump and over time, improve the appearance of laugh lines.
Dermal fillers come in several varieties, but one of the main fillers is found naturally in human tissue, including skin, and performs basically the same job it does when it’s used as a filler: plumping, supporting your skin, collagen stimulation, and hydration. This makes this substance an ideal solution for a filler, which is why it’s one of the most popular types.
How our dermal fillers work
Our dermal fillers actually stimulate collagen and elastin in the skin, so treatments ‘treat’ the skin cells over time, actually improving the skin, instead of simply existing within the skin’s layers.
When using dermal filler to fill out laugh lines around the mouth, the effect is cumulative, so it actually improves your skin until it’s reabsorbed, which naturally occurs over time. This is why further treatments are required, but usually less than before.
About your laugh lines (nasolabial folds)
The anatomical term for laugh lines around the mouth is nasolabial folds. That is, the creases in your cheeks that at their outer edges, start to fold to join the nose – naso – and lips – labial – when we smile. As we age, these folds can become a feature of our faces, instead of just appearing when we laugh or smile. Sagging cheeks contribute to this.
What the research says
One study observed that dermal filler in the nasolabial folds lasted up to 18 months after one treatment. The researchers decided to extend the study up to 36 months to see just how long the dermal filler was effective for after the first treatment. The study therefore included – where appropriate – a second treatment.
The results revealed that out of 52 original patients, 40 required retreatments, but the second treatment took less than 50 per cent liquid of the initial treatment. Ultimately, the study found that 94-100 per cent of the study group maintained at least a little bit of effect for 36 months.
