Keratosis pilaris (KP or “chicken skin”) happens when hair follicles get clogged, usually on the arms, thighs, bottom, or cheeks. It feels rough and bumpy but often improves with over-the-counter acid-based moisturizers.

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 (or ashy) skin is very common and can be triggered by harsh soaps, fragrances, cleaning products, clothing, dry climates, genetics, health conditions, or medications. Luckily, over-the-counter moisturizers usually work really well.
