Let us take a look at the skin benefits soybean oil offers. Keep reading.
Benefits Of Soybean Oil For Skin
1. Helps With Moisture Retention
Applying soybean oil topically helps hydrate the skin from within. It penetrates the skin’s top layers and seals moisture to prevent water loss. In a study, applying soybean oil was found to decrease the transepidermal water loss of forearm skin and promote moisture retention (3).
2. Helps Repair The Skin Barrier
The stratum corneum (the uppermost layer of the skin) acts as a protective barrier against environmental damage. Any disruption of this layer damages the skin. Applying soybean oil to skin is found to improve the skin barrier function due to its soy phytosterol content (3). Another study suggests that applying formulations with soy phytosterols (naturally occurring compounds) may also help in the recovery of skin barrier function (4).
3. Protects Against UV-B Rays
Soybean oil acts as a natural sunscreen with a UV-B filter that reduces skin photodamage. This benefit is attributed to the presence of polyunsaturated fatty acids and vitamin E (5). Its antioxidant properties fight free radicals that cause sun damage and protect the skin from inflammation (6). Soybean oil may help treat irritation and burns caused by sun damage. It protects the skin from UVB with SPF equivalent to 10.
4. May Reduce Signs Of Premature Aging
As per a study, the isoflavones in soybeans may prevent signs of premature skin aging in postmenopausal women (7). Topical application of the oil may reduce wrinkles and fine lines. However, more information is warranted in this regard.
These are the ways soybean oil can benefit your skin. But how can you use it?
How To Use Soybean Oil On Skin?
1. As A Moisturizer
- Pat 2 to 3 drops of the oil on your skin with your fingertips. No need to rinse it off later.
- Repeat once every day.
2. As A Sealant
- Pat 2 to 3 drops of soybean oil on your face after applying your regular cleanser, serum, or moisturizer.
- It helps carry other essential oils/products deep into the skin.
Tip: Applying soybean oil to your skin should be the last step in your skincare routine. Any product with smaller molecules will not be able to penetrate the larger molecules of soybean oil.
Who Can Use It?
Using soybean oil benefits people with dry and combination skin. However, the oil is not recommended for those with oily skin as it may clog skin pores (8).
Soybean oil is often considered safe and non-toxic. However, you have to follow safety precautions to prevent any adverse effects.
Safety Precautions To Follow While Using Soybean Oil For Skin

Also, soybeans are often genetically modified. Hence, look for organic sources.Never apply it to acne-prone skin either on the face or the back.

It also efficiently restores and improves the skin barrier function. Its use might help to calm the skin and maintain it smooth. Soybean oil can be used as a sealant in your daily skin care routine. However, if you are allergic to soybean products, don’t use them. Do a patch test if you are using soybean oil for the first time.
