Hi thanks for writing here.Lomela is a triple combination cream containing mometasone,hydroquinone and tretinoin. All these are depigmentary agents ,it has good results in melasma and skin darkening,but it has to be used under the guidance of a dermatologist.Used for long periods it can produce side effects like skin atrophy,acne,dryness,skin irritation,and excssive darkening of skin known as ochronosis. Since you have used cream for long peroids it is possible that you have either devoloped photosensitivity or ochronosis although it is rare. Stop drug completely,start applying mild cream like kojivit at night time,apply sunscreen at day time ,it is better you consult a dermatologist and take treatment accrdingly.
