Kouyou 5 Step DeTan Kit

Once a week for visible de-tanning results. After reaching your desired tone (typically 3–4 sessions), maintain with fortnightly use and daily SPF application.

The formula is dermatologist-tested. For sensitive skin, do a patch test 24 hours before first use. Skip Step 3 (the acid mask) if you experience any tingling beyond a mild sensation.

Clinical trials show up to 2 shade improvement on the Fitzpatrick scale in 3 weekly sessions. Results vary by starting tan depth, skin type and sun exposure during treatment.

Steps 1–4 are suitable for face and body (neck, arms, back). The serum (Step 5) is formulated specifically for the face. Use a separate body lotion with SPF for body maintenance.
