Ningning's lemon-colored makeup from aespa's 'Lemonade' stage has emerged as a hot beauty trend for 2024. The makeup gained popularity not simply for using yellow, but for strategically placing neon-tinted lemon color to create a more dimensional and glamorous appearance of facial features. In particular, the bright expression under the eyes and inner corner creates a clean impression, leading beauty influencers to share cover videos. Experts have presented four styling formulas for incorporating lemon color into daily looks. First, using a soft lemon yellow tone as a base before foundation effectively corrects redness and dullness in the skin. Second, applying powdery lemon eyeshadow thinly on the eyelids and placing a lemon highlighter on the inner corner makes the eyes appear more defined. Third, drawing lemon or gold-tinted liner along the lower waterline as Ningning does creates a vertically expanded and cleaner-looking eye. Fourth, layering lemon color with coral or apricot blush creates a more dimensional and radiant face. Recently, not only aespa but also other artists have highlighted lemon color, establishing it as the signature color of 2024.
