When you see the likes of Taylor Hill, Kendall Jenner and Malaika Firth storming down the runways, posing near-balletic moves in fashion campaigns and sporting flawless skin in Instagram posts, it's hard to imagine them growing up with the negative side effects of puberty – acne, untameable hair, a fuzzy upper lip.
So, it's refreshing when a model like Puerto Rico-born Natalia Castellar reveals she knows exactly how it feels to be insecure of physical features growing up.
In an interview with W Magazine, the unsigned model – who has posed for the likes of NARS and Mansur Gavriel – admits that her thick, luscious eyebrows haven't always been one of her most desirable assets – for her at least.
'When I was younger they were all anyone would point out. I was bullied terribly because of how thick and long they were, so I wanted to shave them down,' she explains.
Fortunately for the 17 year-old, her mother stopped her before she shaved them off and helped her realise that her thick brows were one of the her defining features.
'It wasn't until thick brows started trending that I started feeling more confident,' she added.
It's not just the brow trend, ignited by Cara Delevingne, that has made Castellar cherish her features, but also her love for their uniqueness.
'Now I don't care if they stay trendy or not, I love my eyebrows. They set me aside from other models. They're my trademark, and I wish I would have embraced them sooner,' she added.
Unfortunately for the teenager – who found fame after her photographer sister shot images of her for Tumblr and Instagram – her days of enduring negative comments from strangers isn't entirely in the past.
'A lot of trolls leave nasty comments about my eyebrows, but I don't give in and respond, because that's what they want. I just disabled my notifications. I want my social media to stay as positive as possible!'
If, like us, you're currently stroking your own brows while reading this and wondering how Castellar has managed to maintain such thick eyebrows, the model has some top tips for keeping the hair in check.
'Many people assume that I have an eyebrow routine that I follow, but I really don't do anything besides brush them. Although it's not much, I think that brushing your brows is just as beneficial as using nourishing products. Brushing stimulates growth, and it helps with circulation,' she explained.
Someone fetch us an eyebrow brush, we're going in.
