Eczema (atopic dermatitis) is common and often gets worse in winter, dry weather, or when you’re sick. Frequent handwashing can make it worse. Daily moisturizers are the best way to prevent flares, and a few extra steps can really help.

Brittle nails are common and can be triggered by age, diet, stress, or climate. Strengthening nail growth usually requires a few changes: vitamin supplements, protective care, and short-term use of a nail strengthener.

Dry eyes are irritating and often lead to rubbing, which can make things worse. As a dermatologist, I most often see this in people taking Accutane (isotretinoin). The good news is that simple over-the-counter products can usually bring relief.

Dry lips are frustrating—they can crack, bleed, and peel. Licking them often makes things worse. Thankfully, some simple over-the-counter products can really help.

Dry hands are common, especially with frequent washing and sanitizer use since COVID. The right over-the-counter products can make a big difference.

Stasis dermatitis (venous eczema) is common in older adults. It causes dry, itchy skin on the shins, ankles, and tops of the feet. Weak leg veins and swelling stretch the skin, leading to eczema. Treatment focuses on compression, leg elevation, moisturizing, and topical medications.

Diaper rash, also called diaper dermatitis, is common in babies and adults using diapers. Irritation from urine and stool causes redness and discomfort. Using barrier creams helps prevent and reduce flare-ups.

Eczema from lip licking is very common, especially in kids. Saliva dries out lips and irritates the skin, causing redness and flakes. Over-the-counter care and willpower can fix it.

Perleche is redness and painful cracks at the corners of the mouth. It’s usually easy to treat with the right over-the-counter products.

Mask-ne was common during the COVID era. It happens when masks trap sweat, oil, and bacteria, clogging pores and irritating the skin. Over-the-counter treatments can help if used correctly.
