It’s not just people who can become Insta-famous, beauty products can too.
In recent years, certain items have gone on to become permanent features in our makeup bags, usually, after rave reviews by beauty bloggers and influencers on Instagram.
Boasting over one million social media followers between them, the duo has created a beauty brand called Summer Fridays.
Haven't heard of it? Well, you've most definitely seen the Instagrammable pastel blue tube of their best-selling Jet Lag Mask all over your social media feeds.
Although still in its infancy, having launched in the US in March 2018, Summer Fridays' one and only product has already sold-out several times over in Sephora and has gained approval from the most powerful influencer of them all, Kim Kardashian West.
"We launched Summer Fridays in March, but we worked on the formula for nearly two years beforehand," Lauren told the Standard.
"We've both tried so many products over the years for our personal blogs, and we felt like there was something missing: clean skincare with good-for-you ingredients and quick results, because we know how busy everyone is. We were able to take what our community had been asking us about skincare for years, and turn it into the perfect product."
So, what exactly is the Jet Lag Mask?
Contrary to its name, you don't actually have to be sat on a plane to use it, it can be used anytime, anywhere, to ensure your skin looks first class 24/7.
The one-of-a-kind hydrating cream, which many now swear by, helps to instantly renew and radiate even the dullest of complexions, thanks to its combination of "ceramides, vitamins, antioxidants, and anti-inflammatory ingredients that help to combat puffy, inflamed, over-worked skin."
The result? After 10 minutes your skin will have an envious dewy glow à la Kim Kardashian.
"We sent her [Kim Kardashian] the mask and she organically showed it which was so kind of her!" Marianna explains.
The famous Kardashian also recently joined Marianna on her Instagram stories to proclaim her love for the product, saying: "You know, I used the Jet Lag Mask before I came here".
Setting it apart from other beauty products, many love the mask as it can be used in a multitude of ways, combining a wash bag full of products into one handy on-the-go tube.
"Jet Lag can be used as a multi-mask from masking, priming skin before makeup and as an overnight mask," says Marianna.
Sharing that her favourite way of using the product is as a primer under makeup, adding: "The creamy formula delivers instant results so you can immediately see that it's working."
Meanwhile, Lauren, a busy mum-of-one, says: "I love to wear it as an overnight mask and I also lather it on my under eyes because #momlife."
Not only is the mask versatile, effective and affordable, retailing for a reasonable £42, but also cruelty-free.
"I was pregnant when we formulated the mask, so it had to remain super clean," explains Lauren.
"We made a specific "NO list" and built our formula without certain ingredients (no parabens, no sulfates, no synthetic dyes or fragrances, etc). The mask is also vegan and cruelty-free because animals are for cuddling, not for testing."
And, it wouldn't be one of the hottest products around right now without its Instagrammable packaging.
"In addition to clean formulas that work, it [the aesthetic] was at the top of our list of priorities," says Mariannah, who alone boasts over 800k Instagram followers.
"We knew as influencers what we like to share and photograph and the more photogenic something is, the more likely we would share it to social. So packaging and design and branding was everything and has helped the success of the brand so far."
The coveted product is finally available to pre-order in the UK, exclusively on Cult Beauty and we're guessing the waitlist is going to be long.
As for what the female beauty pro duo have planned next?
"We're working on future product launches, so stay tuned!" say Marianna and Lauren. Stay tuned, we will.
