Lentigines, also known as freckles, are small dark spots on the skin caused by exposure to sunlight. Antonyms for lentigines are words that indicate the opposite, such as "clear," "spotless," and "blemish-free." These words are often used to describe skin that is free from spots or imperfections. For those who wish to reduce the appearance of lentigines, there are various treatments available, including topical creams, laser therapy, and chemical peels. However, it's important to remember that having lentigines is a normal and natural part of the aging process and should not be considered a flaw or imperfection.
