What Is Stearic Acid And Is It Good For Your Skin?
In the past few years, AHAs and BHAs have blown up the world of skincare. The acids, known as alpha hydroxy acids and beta hydroxy acids, exfoliate without the harshness of a physical scrub. Depending on the specific acid, they can get rid of dark spots and hyperpigmentation, increase cell turnover rate, and shed dead skin, revealing more radiant skin (via Medical News Today).
Despite the skin-saving properties that reside in AHAs and BHAs, using them too often can be detrimental to the skin. According to skincare brand Kate Somerville, exfoliating too much can result in irritation, peeling, breakouts, and sensitivity. Once you've noticed signs of over-exfoliation, you need to dial back the amount of skincare you use and focus on repairing your skin barrier.
The outermost layer of your skin can be fixed by focusing on hydrating and moisturizing in order to bring it back to life. Products with ingredients such as stearic acid can aid in the healing and strengthening your skin barrier.
What is stearic acid?
Stearic acid is a saturated fatty acid that can be found in various plant and animal fats. It's naturally occurring, existing in shea and cocoa butter and coconut and safflower oil. In skincare products, it can be either natural or synthetic, per Paula's Choice.
The yellow-white substance is an emollient, emulsifier, and texture-enhancer, meaning that it hydrates skin, allows oil and water in skincare to mix, and improves the texture of your skincare product, making it easier to spread and apply. It also helps in the repair of the skin barrier, thanks to its ability to keep moisture on the skin (via The Derm Review).
Stearic acid forms a protective barrier around the skin, locking in water. However, it doesn't disrupt the natural oil balance of the skin. It removes excess oil, as well as dirt, bacteria, and grease, making it a gentle yet powerful ingredient in cleansers and soaps.
According to Dr. Axe, stearic acid is suitable for all skin types, especially sensitive and dry skin. It helps with irritability and damage to the skin, so it's a soothing ingredient for skin that reacts to products easily. It holds in water and replenishes the skin's natural oils, moisturizing dry skin, particularly during colder weather.
