Propysalic NF6 ointment contains clobetasol (a strong steroid) and salicylic acid. Since you haven't seen improvement, the marks may not be a steroid-responsive condition, or could be a fungal infection, which steroids can actually worsen. I highly recommend stopping this ointment and consulting a dermatologist for an accurate diagnosis. Depending on their evaluation, alternative treatments may include generic topical antifungals (like clotrimazole) or non-steroidal creams (like tacrolimus). For now, please do not worry; keep your hands well-hydrated using a plain, fragrance-free moisturiser and avoid harsh soaps until a doctor examines your hands.
