Skin care routines and genetics both contribute to younger-looking skin, but free lifestyle factors also make an important difference.
Experts shared the importance of drinking plenty of water and a good night's sleep for helping your skin to glow.
Sleep is one of the most important - yet most affordable - ways to turn back the clock on your appearance, according to experts at beauty and wellness marketplace Fresha.
They said: "Although this may also be obvious, getting enough sleep is crucial for maintaining healthy and radiant skin.

"Therefore, if you want radiant, healthy-looking skin, it's important to be well-rested to prevent these issues and achieve the glow we all want."
While getting a good sleep is often easier said than done, the experts shared some tips for achieving a peaceful night.
They added: "To achieve better sleep, consider reducing screen time before bedtime, practising meditation to promote relaxation and replacing screen time with reading."
Hydration is also vital for plump, youthful skin. There are plenty of hydrating products, such as moisturisers and serums, that will contribute to this.
However, hydration starts from the inside out so it is worth pouring yourself an extra glass or two of water. The experts added: "This one may seem obvious but drinking at least eight glasses of water daily can significantly improve the look and feel of your skin.
"When our bodies are dehydrated, our skin can appear dull and lifeless because it lacks the natural radiance that comes with staying hydrated.
"Drinking the right amount of water also helps flush out toxins that can cause skin issues such as acne or redness, so make sure to drink plenty.
