Understanding Occlusive Ingredients in Cosmetics: Benefits and Risks

What are occlusive ingredients?

Occlusive ingredients are substances used in cosmetic formulations that create a barrier on the surface of the skin, preventing moisture from escaping. These ingredients work by forming a physical barrier on the skin, sealing in moisture and preventing water loss through evaporation.

Examples of common occlusive ingredients include lanolin and beeswax. Vaseline, also known as petroleum jelly, is one of the most widely used occlusive ingredients in cosmetics due to its effectiveness and low cost. Mineral oil is another commonly used occlusive ingredient that is derived from petroleum. Dimethicone is a silicone-based occlusive ingredient commonly used in moisturizers and other skin care products due to its ability to create a smooth, silky texture on the skin.

Potential Risks and Drawbacks of Occlusive Ingredients

This can manifest as redness, itching, or other forms of skin irritation.

How to choose the best occlusive products for your skin

Test new products before use: Before using a new occlusive product, it is important to test it on a small area of skin to check for any allergic reactions or irritation.
