What is 18 but looks younger?

It is not uncommon for individuals to look younger than their actual age of 18. Some factors that can contribute to a youthful appearance include genetics, skin care, and lifestyle habits. Younger individuals tend to have more vibrant and elastic skin, which can contribute to a youthful appearance. However, it is important to note that looking younger does not necessarily indicate a certain level of maturity or experience. It is important to treat all individuals with respect and not make assumptions based on their appearance.
