The Role of Paraffins in Skincare: Understanding Their Benefits

Paraffins in skincare do have a purpose—and an important one at that.

Why the Controversy?

I recently came across a skincare brand’s website that stated they do not use paraffins because they believe paraffins serve no purpose in skincare. This statement implies that paraffins are a useless addition to skincare formulations. Even worse, I have seen claims on various forums that paraffins are dangerous, even carcinogenic. Both of these statements are misleading.

What Are Paraffins?

Paraffins are a common ingredient in skincare formulations. They are derived from petroleum and undergo a rigorous refining process to obtain a purified form suitable for cosmetic and pharmaceutical applications. Pharmaceutical-grade paraffins are meticulously tested to ensure their safety and efficacy in skincare products. In fact, few other skincare ingredients undergo such thorough testing to confirm their purity and safety.

The Benefits of Paraffins in Skincare

Paraffins play a significant role in skincare by providing a protective barrier, sealing in moisture, and supporting skin hydration and healing processes. The misconception that they serve no valuable purpose may stem from their inert nature. However, it is precisely because they are inert and do not penetrate the skin that paraffins are beneficial.

One of the primary functions of our skin is to act as a barrier—not only protecting us from external elements but also preventing water loss. This barrier is often compromised due to skin diseases, environmental factors, and even overuse of active skincare ingredients. Paraffins can serve as a substitute for this compromised seal, offering multiple benefits:

1. Supporting a Compromised Skin Barrier

Paraffins act as an occlusive agent, forming a protective barrier on the skin’s surface. For individuals with conditions like eczema, where the skin barrier is weakened, paraffins help reduce trans-epidermal water loss, restoring and maintaining skin hydration.

2. Calming Skin Reactions, Including in Hospital Settings

Paraffins’ sealing properties can help soothe and calm skin reactions, including inflammation, allergies, and sensitivities. They are widely used in medical settings to treat severe skin conditions requiring inpatient care.

3. Slugging Over Skincare Actives

The skincare trend known as “slugging” involves applying a layer of an occlusive agent, such as paraffins, over active skincare ingredients. This enhances moisture retention and helps active ingredients work more effectively. Slugging can also improve the tolerability of potentially irritating actives like retinoids (though it should not be used over exfoliating acids).

4. Promoting Wound Healing

Paraffins are often applied over surgical wounds and minor cuts to create a moist environment that encourages healing. By sealing the wound and maintaining optimal moisture levels, paraffins support the skin’s natural healing process, reduce infection risks, and enhance overall recovery.

Conclusion: Are Paraffins Safe?

Despite ongoing debates—especially within the natural beauty industry—paraffins are safe and play an essential role in skincare, particularly in skin barrier support and repair. Their ability to retain moisture, protect compromised skin, and enhance healing makes them a valuable ingredient, especially for those dealing with sensitive or damaged skin.

Rather than dismissing paraffins outright, it’s important to understand their benefits and the science behind their use. Skincare should be about effectiveness and evidence, and paraffins have long been proven to be both safe and beneficial.
