The Checkup

Eczema (or dermatitis) is a type of skin inflammation. It can cause dry, itchy skin + rashes or scaly patches on the face, inside the elbows and behind the knees. There’s no one cause of eczema. But genetics, an overactive immune system and environmental + emotional factors play a part.

Prescription eczema treatments include Tacrolimus ointment and Eucrisa, which can help calm the immune response + reduce inflammation. Extreme heat can make symptoms feel itchier + high humidity can trigger eczema flares. So it's vital to keep your body temperature cool + your skin clean and dry.

Rosacea is a genetic condition that largely affects people assigned female at birth (AFAB) over 30. On light skin tones, symptoms of rosacea can look like an overall blush or dry, tight skin with red patches. On dark skin tones, they can look like a dusky brown coloring or areas of darker skin. In severe cases, rosacea can cause red, sensitive pimples + visible blood vessels.

Prescription rosacea treatments include topical Metronidazole and Ivermectin creams, which can reduce bacteria and cell-damaging microorganisms on the skin. Over 60% of people with rosacea say sunlight is their biggest trigger—followed by hot weather flare-ups. So keep covered, hydrate up + try to keep your core body temperature cool.

Spotlight: melasma!

Melasma happens when skin cells create too much melanin—the substance responsible for pigmentation. More common in people AFAB with dark skin, it can cause dark blotches or smooth, freckled patches on the face. Increased hormone levels because of birth control pills, pregnancy + hormone replacement therapy often trigger it.

Prescription melasma treatments like topical creams can reduce melanin production, minimize swelling + help skin turnover. Sun exposure and tanning can make visible melasma more pronounced. So keep your skin covered + use high-quality sunscreen.

Study: 1 in 6 kids have persistent COVID symptoms for 3 months after infection (CIDRAP). 31 studies on 15,000 children show that sleep issues, sore throat + fever are the most common of 20+ chronic symptoms. This area requires more study + we don’t know what this means for long-term development. But this analysis is the largest to date on Covid-19 + kids.

Fatigue Can Shatter a Person (The Atlantic). Post-exertional malaise (PEM) is a crushing form of fatigue. For those with long Covid or ME/CFS, it often follows even mild activity. “If in fatigue your batteries feel drained, in PEM they’re missing entirely.” Read the article for how researchers can identify PEM + how it affects millions.
