Hello. Thank you for writing to us at healthcareMagic The cream that you are using is a prescription product and is a combination of hydroquinone , mometasone and tretinoin. Together this combination is gold standard treatment for facial hyperpigmentation. However this combination should never be used without supervision of a doctor or dermatologist. It should in any case never be used for more than 1-2 months, regularly. Tretinoin and hydroquinone are both skin irritants whereas mometasone is a potent steroid, therefore, it an cause side effects like irritation, redness, burning sensation, skin thinning, sun sensitivity and steroid acne etc if used regularly for more than the permissible limits. I suggest you to discontinue it immediately since you have already been using it for 5 months. Since your skin would be sensitive therefore I suggest you to protect yourself from sun and use a broad spectrum sunscreen throughout the day till your skin recovers back to normal gradually. I suggest you to visit a dermatologist for more details about the usage of this cream, precautions and side effects etc. You may use a moisturizer or a cold cream at night while your skin recovers back to normal Regards
