Change, they say, is inevitable. And while we can neither confirm nor deny what 'they' were talking about, their wisdom certainly applies to the ever-evolving world of beauty.
Although change is a necessary part of life (it would certainly be boring without it), so too is reminsicing on the glorious (and not-so-glorious) beauty looks of years gone by. So, to do just that, we took a walk down memory lane and looked back at some of the most popular beauty trends in history.
Scroll on to see them all.
1965: Brigitte Bardot's bouffant and bangs
French film icon Brigitte Bardot's signature bouffant and tousled bangs ruled the mid-'60s and remain stylish to this day.
1966: Twiggy's dramatic lower lashes
While she was also famous for her pixie cut, Twiggy's dramatic lower lashes (often referred to as 'Twiggy lashes') became synonymous with the swinging '60s.
1967: The pixie cut
Mia Farrow's pixie cut in Rosemary's Baby remains one of the most iconic, trend-setting hairstyles to date.
1968: Cut-crease eyeshadow
Seen on the likes of Diahann Carroll and Sharon Tate, the bold, contrasting look of cut-crease eyeshadow became one of the cornerstones of '60s beauty.
1969: The Flip
Although 'The Flip' hairstyle first appeared in the early '60s on Jacqueline Kennedy Onassis, it made a softer, more relaxed comeback towards the end of the decade on Bewitched's Elizabeth Montgomery.
1970: Long, blunt fringes
The '70s was synonymous with long hair, and thanks to Cher, the long, blunt fringe was no exception.
1971: The centre part
Seventies 'It'-girl Ali MacGraw rose to prominence as an actress early in the decade, simultaneously making her signature centre part one of the most coveted beauty looks of the era.
1972: The pixe-style shag
Cabaret star Liza Minnelli bucked the long hair trend in 1972, with her pixie-style shag becoming one of the most talked-about looks of year.
1973: Extra long lashes
Dramatic lashes took centre stage in 1973, pioneered by the likes of the iconic Diana Ross, who shunned the natural-looking makeup trend of the time.
1974: 'No-makeup' makeup
'No-makeup' makeup largely ruled the early to mid-'70s, as seen here on actress Cybill Shepherd.
1975: Pastel eyeshadows and eyeliners
Thanks to the rise of disco and pop music, pastel eyeshadows and eyeliners gained popularity in the mid-'60s, a look often seen on ABBA's Agnetha Fältskog.
1976: Face-framing layers
Choppy, face-framing layers became de rigueur in 1976, thanks to the iconic Bianca Jagger who gave the shaggy-meets-chic look her stamp of approval.
1977: Farrah Fawcett's famous flicks
After rising to fame as one of the original Charlie's Angels, Farrah Fawcett's signature flicks became one of the most coveted hairstyles in history.
1978: Disco makeup
The height of the disco era saw the return of bold, multi-hued makeup designed to make an impact, as seen here on the inimitable Donna Summer.
1979: Sandy's bad-girl perm from Grease
Big 'bad girl' curls took the beauty world by storm in 1979 after Olivia Newton John's unforgettable makeover scene at the end of Grease.
1980: Statement eyeshadow
A decade of big hair and bold makeup, the '80s started with a bang, led by Blondie's Debbie Harry and her statement-making eyeshadow.
1981: Full brows
Full, thick brows reigned supreme after the now-iconic Brooke Shields made her foray into the world of fashion and film in the early '80s.
1982: The mullet
There's perhaps no hairstyle more synonymous with the '80s than the mullet, a look loved by none other than Australian legend, Olivia Newton-John.
1983: Big hair
The saying "The higher the hair, the closer to God" took on new meaning in the early '80s, thanks to Christie Brinkley's voluminous roots.
1984: Colour-blocked makeup
Pairing graphic eyes with bold lips (and in Cyndi Lauper's case, the side-mullet hairstyle) became the norm as the mid '80s approached.
1985: Teased side-ponytails
Madonna was one of the '80s biggest trendsetters, so it's no surprise that the Material Girl's teased side-ponytail became one of 1985's most popular looks.
1986: Bright blush
A more refined continuation of 1984's colour-blocked makeup, 1986 saw the rise of bright blush paired with a more tonal palette to create a look that was equal parts dramatic and stylish.
1987: Voluminous curls
Everything was big throughout the '80s, and as we know, hair was no exception. Voluminous curls and perms became especially popular in the latter half of the decade, as depicted here on A Different World star, Lisa Bonet.
1988: Blue eyeliner
Although Princess Diana's makeup artist, Mary Greenwell, reportedly didn't approve of the look, the Princess of Wales' famous blue eyeliner became a favourite among women everywhere.
1989: Linda Evangelista's pixie cut
Linda Evangelista not only revived the public's penchant for the pixie cut, but saw her entire career skyrocket because of the style.
1990: No-makeup makeup
The start of the '90s saw the second coming of the '70s no-makeup makeup, but this time with semi-sheer foundation and undone eyes.
1991: Visible lip liner
Visible, un-blended lip liner took over as the 'it'-trend of the early '90s, and saw everyone, including supermodel Naomi Campbell, line their lips three to four shades darker than their lipstick of choice.
1992: Ultra-thin eyebrows
The fact that many of us are still recovering from our over-plucked brows of the early '90s tell us everything we need to know about just how big this trend (unlike our brows) was at the time.
1993: The bare face
The no makeup-makeup took an even more stripped back turn in 1993, as the bare face à la Kate Moss became the preferred take on the trend.
1994: CHANEL's 'Vamp' nail polish
CHANEL's famous 'Vamp' nail polish, a reddish-black hue originally called 'Rouge Noir', rose to popularity after Uma Thurman sported the shade in Pulp Fiction. Interestingly, the famous colour was apparently created from scratch at the famed French maison's 1994 autumn/winter runway show.
1995: 'The Rachel' haircut
When it comes to '90s hair, it doesn't get much more iconic than Jennifer Aniston's 'The Rachel', a layered, face-framing look women took to their hairdressers in droves.
1996: Frosted lipstick
Frosted lips and their shimmery finish slowly emerged in the mid '90s, a subtle sign that the penchant for pulled-back makeup had slowly started to fade.
1997: Metallic eyeshadow
By 1997, bright makeup, and especially metallic eye-shadow, was back in all its glory, as seen here on the then up-and-coming star Jennifer Lopez's shimmery purple lids.
1998: All-over bronze tones
Standout makeup soon gave way to a middle ground between bold and natural, with soft all-over bronze tones taking over as the trending look of 1998.
1999: Meg Ryan's You've Got Mail Shag
Although Meg Ryan's You've Got Mail shag (often referred to as simply 'The Meg') didn't have quite the longevity that 'The Rachel' did, it did become one of the most popular hairstyles of 1999.
2000: Two-tone highlights and crimped hair
Leave it to Beyoncé, ever the over-achiever, to encapsulate two of 2000s' biggest hair trends at once, namely: crimped locks and chunky, two-tone highlights.
