When someone develops new skin issues — breakouts, sensitivity, dryness — the cause is usually a recent routine change. The single most useful diagnostic question: 'What's different about your routine in the last 6 months?'
The common triggers found this way
New cleanser, especially foaming or with fragrance. New retinoid before barrier was ready. Added exfoliation step on top of existing one. New makeup product (foundation, primer) clogging pores. New medication affecting skin (some birth control, antidepressants, steroid courses). Stress increase (cortisol-driven flares).
Why this question works
Skin issues that arrive suddenly usually have a trigger. The trigger is usually something you added or changed recently. Identifying it is faster than buying additional products to 'fix' what the change caused.
Before adding more products to address a new skin issue, audit what changed. Removing the trigger often fixes the problem without requiring new products at all.
