Overview
Moisturizers help hydrate and nourish your skin, but they’re not all created equally. While some feature ingredients that work to supply hydration to the skin’s surface, others include ingredients that smoothen, soften or help protect dry, itchy skin. One of the first steps to restoring a hydrated, radiant-looking complexion is understanding what’s included in your moisturizer formulas (and why).
Ahead, we’re explaining some key facts about moisturizer ingredients—beginning with the differences between humectants, emollients and occlusives. Additionally, we’ll share some examples of each moisturizer type and highlight the CeraVe products you can find them in. By the end, you’ll be equipped with the knowledge you need to build an effective moisturizing routine.
FACTS ABOUT HUMECTANTS VS. EMOLLIENTS VS. OCCLUSIVES
- Fact #1: Moisturizing skincare products typically contain one of these moisturizing agents: humectants, emollients and occlusives.
- Fact #2: Humectants in skin care are ingredients that help support supple, hydrated skin. They work by attracting and retaining moisture in the skin’s upper layer.
- Fact #3: Occlusives in skincare are a type of moisturizing ingredient that creates a barrier on top of the skin—this helps seal in moisture and prevent moisture loss from the skin barrier.
- Fact #4: Emollients are used primarily to help soften and smoothen dry, rough-feeling skin.
Frequently Asked Questions
-
1. Can humectants dry out your skin in certain conditions?
Humectants may draw moisture from deeper skin layers when environmental humidity is very low. Pairing them with emollients or occlusives helps lock hydration in place and prevents potential moisture loss. -
2. Are humectants suitable for oily or acne-prone skin?
Humectants are generally suitable for oily and acne-prone skin because they hydrate without adding heaviness. Lightweight humectant-based formulas can help maintain moisture balance while keeping the skin comfortable and non-greasy. -
3. When should you apply humectants in a skincare routine?
Humectants are typically applied after cleansing and before heavier creams or occlusive products. Applying them on slightly damp skin can help improve moisture absorption and enhance overall hydration within your skincare routine. -
4. What happens if you use occlusives without hydrating ingredients?
Using occlusives alone may seal the skin barrier but does not add hydration by itself. For best results, they are often paired with humectants or hydrating ingredients that draw moisture into the skin before sealing it. -
5. How do emollients improve skin texture?
Emollients help smooth rough or flaky skin by filling gaps between skin cells. This softening effect improves skin texture, leaving the surface feeling smoother, more flexible, and comfortable while supporting the skin’s natural barrier.
