Isolaz Vs. Laser Genesis - Which is Better for Hyperpigmentation & Acne?

Hi, I have sunspots and very mild acne (1-3 pimples monthly, and some enlarged pores on my forehead). Which treatment is best for me? From what I've read, Isolaz is great for acne, ok for hyperpigmentation, while Laser Genesis is better for hyperpigmentation, and ok for acne. Would combining a photofacial to the service be beneficial for me (or would just the treatment alone suffice)? Thanks for your help!
