I heard a dermatologist say that patients with melasma should use sunscreens containing both zinc oxide and iron oxide. Do iS Clinical sunscreens contain both of these ingredients?

Eclipse SPF50+ contains micronized zinc oxide, iron oxide, and micronized titanium dioxide. The inclusion of opaque iron oxides in sunscreens may be beneficial for melasma by improving SPF ability; while helping to physically cover the pigmentation. Adequate solar protection is a must for any type of hyperpigmentation, including melasma.
