Makeup is meant to enhance your features, but even small mistakes can affect the final look. One of the biggest mistakes is using the wrong foundation shade—always test on your jawline, not your hand. Overdrawn eyebrows can make the face look harsh; instead, follow your natural shape and fill in with light strokes. Skipping primer often leads to patchy makeup, especially on oily or dry skin. Another common error is too much contouring or highlighter, which can look unnatural—blend well for a seamless finish. Avoid clumpy mascara by using a lash comb and replacing mascara every 3 months. And lastly, ignoring skin prep (cleansing and moisturizing) before makeup makes even the best products look cakey. A flawless look is all about balance—less is more when applied with the right technique.
