Sunflower oil is one of the centuries-old beauty secrets. Science has now shed light on the benefits of sunflower oil. Many dermatologists approve it for its hydration, antioxidant, and anti-inflammatory properties. It is more beneficial in skincare formulations, especially pH-balanced products, rather than raw application.

Understanding the Limits

Understanding the Limits

After reading all the benefits and advantages of sunflower oil, you might want to go straight to your kitchen and apply the oil from the bottle. But here is the catch: untested and unrefined oils might not be pure enough or stable enough to be applied to the skin.

Always be cautious in what you apply to the skin, especially when it comes to DIY oils. They might be oxidized, impure, or have disrupted pH. So, what should you do? You must look for good skin care formulations that are dermatologically tested for your skin. A good sunflower oil-based moisturiser can be your best friend, especially for people with eczema and other skin conditions.

The Bottom Line

Sunflower oil is a versatile ingredient. It is a kitchen staple as well as a skincare gem. It has components like linoleic acid and vitamin E, which are antioxidants, anti-inflammatories, and hydrating.

Although it is non-comedogenic, sunflower oil must not be used in raw form. You should look for barrier creams or other products containing cold-pressed sunflower oil as their primary ingredient.

For people with eczema, sunflower oil-based products can be very beneficial. It can help maintain their skin barrier, replenish ceramides, restore skin pH, while hydrating the skin deeply, giving you a healthy, glowing, resilient, and younger-looking skin.
