With a multitude of tricks and hacks to avoid ageing, it isn't easy to decide which method to start doing that will guarantee a younger and fresher look.

Luckily a 50-year-old woman, who claims she looks 15 years younger, has taken to TikTok to share her most "powerful" beauty secret, but it isn't what you think.

The creator who goes by the username, Michelle Silva, currently boasts 72,000 followers and is known for manifesting youth with a timeless beauty mindset.

Beginning her video, which she titled 'The best anti-ageing secrets to look 15 years younger', she said: "The best anti-ageing beauty secrets from a 50-year-old who has mastered a youthful appearance and the last one is the most powerful of them all."

The first tip she shared is quite common and known in the beauty world - staying away from the sun.

Michelle stated: "Number one, stay away from the sun, get an effective mineral sunscreen, and always wear a hat and sunglasses when outdoors."

Too much exposure to the sun's ultraviolet (UV) rays can have harmful effects on your skin causing sunburn that can blister and peel the skin and in turn, promote premature ageing leading to leathery and wrinkled-looking skin.

Her next tip is to get eight hours of sleep, she said: "Eight to nine hours of sleep, it's called beauty rest for a reason. Getting eight to nine hours of sleep gives your skin the best chance to repair, regenerate and stay youthful. Prioritising sleep is the simplest and most effective way to maintain a radiant, youthful complexion."

Michelle's third step is skin care, she suggests using vitamin C, retinol, a moisturiser and sunscreen. However, her last and "most potent" anti-ageing secret is "tapping into the dormant power in your mind when it comes to ageing."

She shared: "I call this timeless mindset. Every thought or idea that you have about getting older causes a physical reaction, your thoughts have consequences and create chemical reactions in your body.

"The mental images you have about yourself, whether real or imagined is what your brain and nervous system respond to, so when you worry about getting older, you're programming a picture that you don't want and your subconscious mind is a genie that says your wish my command. So it fulfils the picture that you put there.

"The beauty industry, classifies mature skin at 40, if that's what you say and that's what you believe, then your wish is my command, your imagination and your ability to see yourself younger, the belief you have that you can slow down the ageing process are more powerful than any medical data that can prove it cannot be done."

Michelle concluded: "Yesterday I turned 50, and I can promise you that once you start adopting new beliefs, you can prevent premature ageing, slow down ageing and even reverse ageing and once you incorporate all these anti-ageing secrets you can look better at 50 than you've ever looked in your 20s, 30s, and 40s."
