Propylene glycol is an odorless and colorless liquid known for its hydrating properties. It attracts and seals skin moisture. It is an excellent humectant and is used in many products, including moisturizers, shampoos, conditioners, and serums.
It helps improve skin texture and promotes the absorption of other ingredients. Propylene glycol is also used in other industries as a solvent, an emollient, a humectant, and a preservative (1).
But is propylene glycol safe for your skin? Contrary to what many believe, propylene glycol is safe for use unless you are allergic to it. The WHO has set its daily intake limit to 25 mg per kg of body weight (2). It is also approved as a safe additive to food by the FDA and completely safe for human use (3).
Stylecraze SaysTo maintain the effectiveness of propylene glycol, store it at an ambient temperature and airtight container. Do not expose it to sunlight or other UV light sources.
In the following section, we will see how this ingredient can benefit the skin.

Propylene glycol is popular for moisturizing and smoothening the skin (1). Propylene glycol is an odorless and colorless liquid known for its hydrating properties. It is ideally used in products made for dry and combination skin types, and skin that is parched or flaky. The humectant properties of propylene glycol attract water and seal it onto the outer skin layer.
Propylene glycol also works as an emollient and softens and soothes the skin (4).

2. May Improve Skin Texture
Propylene glycol protects your skin from excess dryness and prevents damage caused due to external oxidative factors. This may improve skin texture too. However, more research is warranted in this regard.
3. May Help Treat Acne
Moisturizers that are usually oily can aggravate acne. Propylene glycol is water-based, light in texture, and non-sticky – and can hence be safe on acne-prone skin. However, the acne-fighting properties of propylene glycol are yet to be studied.

4. May Prevent Premature Aging
There is limited research available here. But anecdotal evidence suggests that the natural moisturizing capabilities of propylene glycol may help reduce the signs of premature aging. Dry skin is more prone to flakiness, wrinkles, and fine lines. Propylene glycol may keep skin moisturized and prevent the signs of premature aging.
5. Promotes Better Absorption Of Other Skin Care Products
Propylene glycol is known to help the active ingredients present in other cosmetic products reach deeper into the skin, thus improving their efficacy and results (5).
6. Safeguards The Skin Barrier

Another lesser-known benefit of propylene glycol is it protects your skin barrier (6). The humectant properties of this ingredient can help safeguard the skin barrier, especially for people with skin conditions like eczema and psoriasis.
Since propylene glycol has so many benefits, it is easily one of the most used ingredients in many skin care and cosmetic products. However, it is often confused with ethylene glycol. But the two are completely different compounds. The following section discusses these differences.
Propylene Glycol vs. Ethylene Glycol
Propylene glycol and ethylene glycol are both known to be used as anti-freeze in many industries.
That said, ethylene glycol is severely toxic and may be completely unsafe for skin applications. Propylene glycol, on the other hand, has a very low level of toxicity and is safer for use. It is suitable for more skin types.
Though propylene glycol is the safer of the two, it still does have some side effects. We discuss the same in the next section.
Side Effects Of Propylene Glycol
- People with eczema may develop irritation to propylene glycol. They are advised to do a patch test before utilizing products with this ingredient.
- Continuous use of propylene glycol around your eye and nasal region may cause irritation.
After considering all its benefits and side effects, you may go for products containing propylene glycol if it suits your skin type. Here are the various ways you can use these products.

Propylene glycol is present in many skin care products mainly because it helps skin retain its moisture and stay soft and smooth. But some believe using propylene glycol for skin is not safe as it is derived from petrolatum. However, it is safe to use on skin as the cosmetic-grade petrolatum is safer and more refined than commercially used petrolatum.
