A few common questions

Which guide should I read first?

Start with the complete guide, then choose the concern or treatment question that best matches what you want to understand.

Can these guides diagnose my skin?

No. These are educational guides, not an individual diagnosis or treatment plan. A clinician licensed where you live can assess symptoms and discuss appropriate care.

What if my symptoms are worsening?

Persistent or worsening symptoms deserve a clinician’s assessment. If products are making your skin uncomfortable, do not use a general guide as a reason to continue an irritating routine.
