What does "suits my skin" actually mean?

"This product didn't work for my skin." "I feel like this one suits me." These are among the most common phrases in skincare conversations, but what does "suits" actually mean?

In most cases, "suits" is judged by sensation. No breakouts after using it, pleasant feel on the skin, a vague sense that things are better. These are all based on "feeling."

Feelings Matter, But Lack Reproducibility

Feelings matter, but they lack reproducibility. What suited you yesterday may not suit you today. Season, stress, and lifestyle changes cause your skin's condition to shift daily.

Judging "Suits" by Results

Truly "suiting your skin" means not just avoiding irritation, but that your skin's condition has improved compared to before use. Try using the same product for one month and observe changes in skin texture, how long dryness persists, and how well makeup applies.

Judging "suits" by "results" rather than "preference". This is the first step toward moving skincare from feeling to science.
