The steps.

  1. 01
    Step 1

    Kaolin clay mask

    10 minutes, do not let dry fully

    A 10-minute clay mask draws sebum and surface debris without the over-drying that comes from leaving it on until cracking. Apply to clean, slightly damp skin. The mask should still feel cool when you remove it.

    BHA 2% leave-on

    15-minute dwell, do not rinse

    After the clay mask is removed, apply a thin layer of 2% salicylic acid to dry skin. Allow it to dwell for 15 minutes — this is the active step that delivers the actual exfoliation. Do not stack with retinoids on the same night.

    Step 3

    Barrier seal moisturiser

    Generous, ceramide-rich

    After the BHA dwell, apply a thicker-than-usual layer of ceramide moisturiser. The night of the reset is not the night to add anything else — no retinoid, no acid serum, no fragrance. The point is recovery as much as exfoliation.
