A weekly 5-minute skin check is the single most useful habit for catching skin issues before they need expensive fixes. Five minutes on Sunday evening looking at your skin in good light prevents months of escalation.
What to check
New spots, moles, or texture changes (dermatology referral threshold: new spot that grows, bleeds, or has irregular borders). Patches of dryness or redness that have been there 2+ weeks (barrier check). Persistent breakouts in a new area (track for trigger). Hyperpigmentation worsening (sun protection check).
What to act on this week
If something has been bothering you for 2+ weeks and over-the-counter response hasn't fixed it, book a GP or dermatologist appointment. Persistent issues rarely resolve on their own; chronic skin problems usually have specific treatable causes.
Most skincare improvement comes from boring weekly maintenance, not from buying new products. Five minutes a week catches what daily routines miss.
