In some cultures, yes, dimples are associated with beauty and good luck.
While the presence of dimples is generally considered an attractive trait, their association with good luck is primarily a cultural belief. Whether or not someone actually considers dimples lucky is subjective and varies across different regions and personal beliefs. The prevalence of dimples is only around 20-30% of the population, which may contribute to the perception of them being special or fortunate. Therefore, whether dimples are "good luck" is not a scientifically proven fact but rather a cultural perspective.
