Occlusive products are a type of skincare product that is designed to create a barrier on the skin’s surface, preventing the loss of moisture from the skin, and helping to maintain the skin’s natural barrier function. These products are typically thick and heavy, and they work by forming a physical barrier on the skin’s surface, which helps to trap moisture within the skin.
The primary benefit of occlusive products is their ability to reduce transepidermal water loss (TEWL), which is the process by which water evaporates from the skin’s surface into the surrounding environment. TEWL is a natural process that occurs in all skin types, but it can be particularly problematic for individuals with dry or dehydrated skin, as it can lead to further dehydration and irritation.
By creating a physical barrier on the skin’s surface, occlusive products can help to slow down the process of TEWL, keeping moisture within the skin and reducing the risk of dehydration. This can help to improve the overall health and appearance of the skin, leaving it looking plump, hydrated, and radiant.
In addition to their moisturizing benefits, occlusive products can also help to protect the skin from environmental stressors such as pollution, UV radiation, and harsh weather conditions. By creating a barrier on the skin’s surface, these products can help to prevent these external factors from penetrating the skin, reducing the risk of damage and irritation.
There are many different types of occlusive products available, including:
- Petrolatum (Vaseline)
- Mineral oil
- Lanolin
- Beeswax
- Shea butter
- Jojoba oil
- Argan oil
- Coconut oil
Occlusive products can be used on all parts of the body, but they are most commonly used on the face, hands, and feet. They can be applied as a moisturizer, a lip balm, or a body oil.
A moisturizer typically contains three primary ingredients: occlusives, humectants, and emollients. Below is a concise explanation of each component and their role in preserving the skin’s moisture:
- Occlusives: Occlusives are ingredients that form a protective barrier on the skin’s surface, helping to lock in moisture and prevent water loss. By doing so, they maintain the skin’s hydration levels and improve its overall appearance. Examples of occlusive ingredients include petrolatum, beeswax, and shea butter.
- Humectants: Humectants are substances that attract and bind water molecules, drawing moisture from the environment and the deeper layers of the skin to the outer layers. This keeps the skin hydrated and plump, reducing the appearance of fine lines and wrinkles. Some common humectants include glycerin, hyaluronic acid, and propylene glycol.
- Emollients: Emollients are ingredients that soften and smooth the skin by filling in the gaps between skin cells, improving the skin’s texture and elasticity. They also help to restore the skin’s natural lipid barrier, which is essential for maintaining moisture and protecting the skin from external irritants. Examples of emollient ingredients are fatty acids, ceramides, and oils such as jojoba oil and almond oil.
