How long I should leave part 1 cosmelan on? (Photo)

I've purchased cosmelan to apply at home. I consider myself light toned with some German, Portuguese decent. My biggest problem areas are around my lips and cheek bone areas.

Cosmelan has an at home treatment which is not as strong as the MD preparation.  The MD preparation which is placed only in a doctor's office has hydoquinone and Retin-A compounded into the preparation.  The time left on is followed by guidelines from 5 or more hours depending on skin type.  Since this is a weaker preparation you should contact the company itself for guidelines.

How long does Cosmelan stay on?

Cosmelan is almost always applied in a doctor's office because it has to be done a specific way..... You leave it on for 6-8 hours, but the physician and medical staff determine that. From your photos I don't see melasma which is what this treatment is for. I see other sun damage, freckles, and sites, but Cosmelan is not a treatment for those.
