How to read a moisturizer label

A few familiar words can make the packaging easier to understand. Here’s a starting point.

Key takeaways

  • Start with the product type: lotions, gels, creams and ointments are all moisturizers with different textures and compositions.
  • Humectants attract and retain water in the outer layer of skin; occlusives help reduce water loss by forming a barrier.
  • An ingredient's role describes how it functions, not how well a particular product will suit your skin.
  • If you are unsure about a product, bring its name and ingredient list to your dermatologist.

The short answer

Start with the product type and what the ingredient terms mean. A single ingredient does not tell you everything about the finished formula.

First, understand the product type.

Moisturizer is an umbrella term: lotions, gels, creams, and ointments can all belong to this category. Their textures and composition differ. The American Academy of Dermatology explains these differences in its moisturizer guide.

Then, get familiar with ingredient roles.

Humectants attract and retain water in the outer layer of skin. Occlusive ingredients help reduce water loss by forming a barrier. These are descriptions of how ingredients function, not a score for how well a particular product will suit you. DermNet explains these ingredient groups.

Keep the whole formula in mind.

Understanding the terminology can help you ask better questions. It does not replace a conversation about your individual skin concerns or any treatment you have been prescribed.

If you’re unsure about a product, bring its name and ingredient list to your dermatologist so you can discuss it in context.
