01 / COMMON CONTEXTPattern before product.
The central face—cheeks, nose, chin and forehead—is typical. Eye irritation, lid symptoms or changes beyond the face need appropriate assessment.
Sun, heat, alcohol, spicy food, stress and irritating skin-care ingredients can trigger some people, but a personal diary is more useful than a universal blacklist.
02 / ROUTINE FOUNDATIONKeep the base calm.
Use a mild cleanser, fragrance-free moisturiser and broad-spectrum SPF 30 or higher. Apply products gently and let treatment dry before layering when advised.
03 / FORMULA DIRECTIONChoose by function.
Glycerin, ceramides, hyaluronic acid, squalane and dimethicone can appear in gentle facial moisturisers. A short, well-tolerated formula is preferable to a crowded active routine.
