If you've been watching Love Island these last seven weeks, you've surely asked at least one of these questions: How can they wear so much makeup in the sun? What did Liam just say? How to they keep their bikini lines so smooth and bump-free?

Well, seeing as we can't answer them all, we'll focus on the last one – getting a smooth, clear and healthy bikini line before the summer is out.

TikTok has become a treasure trove of tips and tricks, and shaving tips have boomed on the social media platform. People all across the world have been sharing their own hacks for getting a bikini line worthy of a hot girl summer, but – as with any information shared on social media – you have to be careful what you believe.

So we asked two Dublin-based experts, Jennifer Treanor of UrbanWax and Marjorie Cusack of Wax in the City, for their help separating fact from fiction.

According to Jennifer, key to the Love Island look is that "there is no line to be seen" as "the girls appear to have all bikini hair removed, also known as a Hollywood".

She adds: "In preparation to the lead up of going to the Love Island some may wisely have had Laser hair removal. Laser is very effective and results give permanent hair reduction. It Is long term low maintenance and has an advantage to stimulating collagen so it gives a very smooth look and feel to the treated area."

However, as Marjorie says, Laser might not suit everyone: "It is not a forever solution but it does lighter the hair and the regrowth allowing for longer gaps between waxing."

Going to these lengths makes sense for the islanders, as "being filmed must put extra pressure on everyone to keep their bodies hair free", Jennifer adds. But what about those of us who just want to look their best going for a sea swim?

Shaving your own bikini line is a tricky job, and as many TikTok users have pointed out, it's not something you're given a lesson about thanks to the nature of the area.

Razor burn – mostly caused by dry shaving but can also be caused by not taking care when wet shaving, according to Jennifer – and ingrown hairs – when the hair grows back into the follicle, creating a painful and unsightly bump – are the two most common forms of irritation, and TikTok is awash with hacks for getting the smoothest shave possible.

But do they work?

Exfoliating is usually listed as a must, which Jennifer agrees with: "Exfoliating is a huge benefit for our skin regardless whether we are removing our hair or not. Always do this 2/3 days before waxing or having a Laser treatment. If shaving the day before is fine. Exfoliating is recommended for the body once a week."

Using a men's razor is a popular go-to on TikTok, thanks to them having more blades, but Jennifer says that while this seems to be true, she finds "the traditional disposable razors the best and most effective". Marjorie, meanwhile, maintains that there's "no difference", adding that "they are the same, it's branding".

A very popular tip is to shave with coconut oil rather than shower gel or a shaving cream, with users saying it leaves the skin polished and moisturised after. Jennifer agrees that coconut oil is great for shaving with, but adds that "you need to ensure you keep removing the oil build up on the blade". She adds that an older hack was to use hair conditioner after shaving, as "it always leaves a smooth finish and it's always in the shower".

"There is a multitude of choice in shaving products out there but I don't think they are all necessary. A good moisturiser after shaving/waxing I feel is far more important", she adds.

As for waxing, Marjorie has some top tips herself: "You need to ensure is with a high quality hot wax, there is no cross contamination during treatment, the wax is clean and the treatment is carried out by a highly trained operative.

Not every form of hair removal is suited to everyone, however, so Jennifer recommends talking to a specialist to find the one best suited for you. "Any form of grooming in the bikini area risks the possibility of irritation and not all people are suited to one type of hair removal", she says.
