'I'm almost 50 and I still get asked for ID - my secret might surprise you'

A woman has shared that she may be 50 at her next birthday, but she looks more youthful than ever, thanks to several secrets. Caroline Butler, who posts on Instagram at @caroline.shops, shared that she's "never had botox," has never "had any fillers," nor has she had any "aesthetic surgery". Caroline even boasted that she didn't even have a filter on the video, proving how she certainly doesn't look her age.

"In fact, I sometimes get asked for ID when I buy wine in the likes of Tesco," she shared, saying that she was going to share her "secrets" for "staying youthful".

1. She barely drinks alcohol

First, Caroline said that she "very rarely" drinks alcohol, saying she's "pretty much teetotal the majority of the time".

According to Drink Aware, when you drink, the dehydrating (or ‘diuretic’) effect of alcohol means your skin loses fluid and nutrients that are vital for healthy-looking skin. This can make your skin look wrinkled, dull and grey, or bloated and puffy. Dehydrated skin may also be more prone to some types of eczema.

Limiting the amount of alcohol you drink and having plenty of water or soft drinks between alcoholic drinks can help avoid dehydration.

2. She doesn't smoke

Caroline shared that she doesn't smoke, and she "has never smoked". According to Action on Smoking and Health, several studies have found that smoking is an independent risk factor for premature facial wrinkling and facial ageing, and the more a person smokes, the greater the risk.

3. She's a vegetarian

According to Hans Place, it's "impossible" to say people eating a plant-based diet look younger, as there are so many other factors at play. However, there may be more collagen-boosting properties in a diet like this, which could mean the person looks more youthful.

But, Caroline shared: "I'm a vegetarian and I have been for the majority of my life," as she credits this, in part, to her youthful appearance.

4. She wears SPF

Caroline shared that she wears "factor 50 or factor 100" on her face every single day, "no matter what the weather".

It's well known that sun cream can help you look younger by preventing premature ageing caused by sun damage, protecting your skin from harmful UV rays, which are a major contributor to wrinkles, sunspots, and loss of elasticity.

5. She never sunbathes

UV rays can be harmful, so Caroline thinks avoiding the sun means that she has a more youthful appearance than those who love sunbathing.

6. She's a big believer in positivity

Caroline said: "I'm a big believer in positivity, and I believe that if you keep a positive mindset, then it makes you more youthful".

7. She doesn't have children

"Finally, I chose not to have children, and I currently don't have a boyfriend or a partner," she shared, admitting at the end of the video that she's "probably inherited some pretty good genes" as well.

In the comments of the video, many complimented her, saying things like: "Wow, you really look like you're 30," and "Wow, you look amazing".

Others shared: "It’s the kids that did it. I’ve aged SO FAST in the last decade," and "No children and no partner, that’ll do it! You look amazing. I aged 80 years after meeting my husband and having our son".

One woman said that "50 is not old, it is a youthful age these days," which many were pleased to read.
