Hi Johan! Welcome to dermatalk, you seemed to have used hydroquinone, tretinoin and strong steroid( which is usually contraindicated for face)on your face. They altogether have whitening effect but strong sunprotection is must on the process of treatment otherwise as they make your skin very sensitive to sunrays you may have opposite effect. Thus using triple combination cream contaning hydroquinone ( or kojic acid), tretinoin, and low potency steroid at night with complete sun protection with sunscreen of SPF 30 or above with reapplication every 4 to 5 hours on day may help be helpful.
