TikTok Says This £8 Ingredient Mimics The Results Of Lip Filler

TikTok is well known for its ability to spark a myriad of beauty trends – some more questionable than others. But some, it would seem, are actually worth their salt. Take the currently viral hypochlorous acidspray for starters, which has gained the seal of approval from experts the world over. And now another acid is having its moment the spotlight. Specifically, hyaluronic acid.

At this point, it’s an ingredient well known in skincare circles for its ability to soothe, moisturise and plump thanks to its ability to help the skin retain moisture. But TikTok creators have gone a step further, applying it to their lips and touting it as a replacement for filler - there's a reason why 'hyaluronic acid serum for lips' is currently a breakout search term on Google. It’s interesting stuff, granted. But is there something in the trend or is the topical application of HA a waste of time? Dr Sonia Khorana, a GP with a special interest in dermatology, weighs in.

Does hyaluronic acid plump lips?

‘The dermal fillers that we use for lip fillers are made from hyaluronic acid and are used due to their moisture-retaining properties,' explains Dr Khorana. 'When used in fillers, HA can help improve volume loss and hydration of lips from within.’

That's all well and good, but how about this new topical application as beloved by the TikTok community?

'Applying hyaluronic acid topically is actually a great idea,’ confirms Dr Khorana. ‘It is a great humectant and hydrates your lips. I always recommend sealing in this hydration with an occlusive such as Vaseline on top – often called “lip slugging.”'

Moisturised lips equates to plumper looking lips. So, while it's unlikely you'll see the same results that someone might get using injectable lip filler, you will still see a plumping effect from regular topical application.

Is hyaluronic acid good for lip lines?

Fine lines around the lips are normal as we age – as are the deepening of the creases on the actual lips themselves. If either of these bother you, then hyaluronic acid could be a good option.

‘HA has moisture retaining properties and helps to temporarily fill in fine lines on the lips, making it an excellent base for lipsticks or glosses, preventing them from cracking or drying out the lips,’ says Dr Khorana.

Does hyaluronic acid lighten lips?

Will putting hyaluronic acid on your lips make them appear lighter?

‘Hyaluronic acid helps to hydrate and improve the appearance of fine lines and wrinkles, but it cannot lighten lips specifically as it is not a tyrosinase inhibitor,’ explains Dr Khorana. ‘The improved hydration and plumpness from HA may make your lips look brighter, however, especially if they are dry and that dryness is contributing to darkness.'

If you struggle with lip pigmentation?

‘I’d recommend using daily sunscreen but also to avoid licking your lips and to step away from irritants like menthol or mint in lip balms. You should also incorporate ingredients like lactic acid, vitamin C, and kojic acid,’ she adds.
