There aren't any specific antonyms for the word "puffinesses" as it is already a plural form of "puffiness", which means swollen or enlarged due to fluid buildup. However, some possible antonyms for the concept of puffiness could be words such as flatness, deflation, shrinkage, slimness, or reduction. These antonyms imply a decrease in size or volume rather than an increase, and could be used to describe the opposite condition of puffiness, such as a flattened, shrunken, or slimmed appearance. Alternatively, words such as firmness, tightness, or tautness could represent the opposite sensation of puffiness, which is loose or flabby skin due to excess fluid or fat.
