I actually quite like Marigold, but her skin has been driving me insane since that first time in CoD that Dora suggested a makeover. Of course some acne/face rashes/etc can't be prevented, but the blackheads and stuff, augh. Even if she wasn't gross and pop-y with them, they're easy to get rid of. Hot water, maybe exfoliate, use an oil cleanser and a good moisturizer, use some salicylic acid to chemically exfoliate the pores now and then. Since she has had it forever and it's America so prescriptions (if they were needed) are more expensive, I understand that it wouldn't get perfect, but it could be a lot better.
Her hygiene has been getting better since before Faye and Angus, and Hanners has great hygiene and good skin, so I can't imagine why she hasn't gotten onto some kind of skin care, even if it's just a drug store wash and moisturizer.
(although her skin got notably better right started having hygiene and lost the rats, it hasn't really since then)
Just a barely-related complaint, I was looking at her face in the last panel.
