Sensitive-skin protocol
- Patch test for 3 days: apply to one or two small areas (e.g., behind the ear) once daily.
- Start once daily, in the evening, with a single product (Face Wash is the gentlest entry).
- Add products one at a time, a week apart, before building to the full routine.
- A brief tingle in the first applications is normal for an effective low-pH exfoliant. Persistent stinging, redness, or peeling means reduce frequency to once a day or every other day.
