I have been prescribed Kojiglo forte ( Has hydroquinone 2% and other compounds ) for 4 weeks. It's currently my second week now. I wanted to ask do I need to abruptly stop it at the end of 4th week or should I withdraw it slowly in the 4th week by using it only twice or thrice a week ??? ( This was prescribed for my hyperpigmentation all over my face )..... Also I have a prp and Derma pen session scheduled next month how many days gap should be kept between stopping hydroquinone and doing the prp with Derma pen. ( I am scared something could go wrong if I do prp with Derma pen while on HQ or immediately after stopping it )
