For very dry skin, look for moisturizers containing occlusive ingredients like shea butter, petrolatum, or ceramides. These create a barrier to prevent moisture loss. Also, consider using a thicker cream or balm formulation.

There's no single universally recognized "no. 1" moisturizer. The best moisturizer depends on individual skin needs and preferences, so look for highly-rated and reviewed products with ingredients known to hydrate and repair the skin barrier.

Dryness despite moisturizing can stem from several factors. You might not be using the right type of moisturizer for your skin, or external factors like harsh cleansers, weather, or underlying skin conditions could be contributing.

The 3-minute rule suggests applying moisturizer within three minutes of cleansing. This helps trap moisture into the skin while it's still damp, maximizing hydration and absorption.
