Is it safe to use hydroquinone products, such as Carolight, whilst on Accutane? Can it cause hyperpigmentation?

I have really uneven skin, and dark spots with hyperpigmentation around my lips. I’ve been using a hydroquinone based product called Carolight (recommended by a family member) to even my skin tone, and it’s been working pretty good, I started my Accutane treatment a week ago and notice that my skin is slightly getting darker in some areas and it is really bothering me. If hydroquinone is not safe is there any other procedure, treatment or products that will help even out and lighten my skin?
