Tru-Skin Blog - The Ultimate Guide to Petrolatum and Slugging: Debunking Myths and Revealing Benefits

Have You Heard About Slugging?

It’s a recent skincare technique that’s taking the world by storm. Slugging involves applying petrolatum-based products like Vaseline to your skin to lock in moisture. But is it safe? Will it clog your pores? In this comprehensive guide, we’ll explore the benefits and potential drawbacks of using petrolatum-based products for skin hydration, including a comparison between using petrolatum and the skincare technique known as “slugging.” We’ll address concerns related to clogged pores and acne while explaining the science behind how petrolatum locks in moisture.

Petrolatum

Petrolatum, also known as petroleum jelly, is a semi-solid mixture derived from petroleum. It forms a protective barrier on the skin’s surface, preventing moisture loss and promoting healing. It has been used for over a century for various skin ailments and is considered safe by the FDA. Some people avoid it due to its greasiness and pore-clogging concerns, but studies show it is non-comedogenic. The American Academy of Dermatology recommends it for eczema or dry, cracked skin.

Slugging

Let’s talk about slugging. According to Consumer Reports, slugging is a skincare trend that involves applying a thick layer of petrolatum-based products to your face at night for hydrated skin. Vaseline is commonly used, but other products like Aquaphor or lanolin work too. Slugging creates a barrier to retain moisture and protect against irritants.

Some people have reported improved hydration, acne, and eczema symptoms from slugging. However, it’s not suitable for oily or acne-prone skin as it can worsen breakouts. Patch testing is essential to check for allergies.

Remember, use petrolatum-based products as the last step in your skincare routine. Don’t apply them to open wounds or broken skin, as it can delay healing.

Is Petrolatum Suitable For All Skin Types?

While petrolatum is one of the oldest skincare ingredients and has been used for decades to protect and soothe the skin, it may not be suitable for all skin types. The American Academy of Dermatology Association doesn’t recommend applying petroleum jelly on your face if you are acne-prone. Here are some general tips on its usage:

Patch Testing

Patch testing is an essential step in determining whether a skincare ingredient is suitable for your skin. This involves applying the product to a small patch of skin (such as the inside of the wrist) and monitoring for any adverse reaction over 24 to 48 hours. If you experience redness, itching, or swelling, this may indicate an allergy or sensitivity to the ingredient.
