Dry skin is usually a barrier and moisture issue, not an oil issue. Layer water, then seal it.

Key takeaways
Dry skin is one of the most common concerns, and one of the most misunderstood. The first distinction matters: dry skin lacks oil, while dehydrated skin lacks water. You can have oily and dehydrated skin at once. Most “dry” concerns are actually a combination of both, and the fix is layering, not a single rich cream.
The reliable approach is to add water-based hydration first, then seal it in. A hyaluronic acid serum applied to damp skin draws moisture toward the surface; a moisturiser with emollients and occlusives then prevents it from evaporating. Skipping the seal is why many people feel dry again within hours.
Watch your cleanser
The most common cause of dryness is the cleanser, not the moisturiser. Foaming cleansers with strong surfactants strip the barrier. Switching to a gentler cleanser often resolves dryness more than any new cream.
If dryness is persistent, cracked, itchy or accompanied by redness, it may reflect a condition like eczema that needs medical care rather than cosmetics. The National Eczema Association is a useful starting point for distinguishing everyday dryness from something that needs a clinician.
