In recent years, skincare products have become an essential part of our daily routines, promising to nourish and revitalize our skin. However, not all ingredients are as harmless as they seem. One such ingredient, sodium hydroxide, has raised concerns among skincare experts due to its damaging effects on the skin when left on the surface for extended periods. Often used in face creams, serums, and lotions, sodium hydroxide, also known as lye, is the main component in soap. But, why does it pose a threat when used in skincare products?
Â
Sodium hydroxide is a potent alkaline compound known for its corrosive properties. When present in skincare products, especially those left on the skin for prolonged periods, it can lead to severe irritation, redness, and even chemical burns. Unlike soap, which is rinsed off after use, face creams and serums containing sodium hydroxide are designed to stay on the skin to deliver their intended benefits. This prolonged exposure increases the likelihood of skin damage, especially for individuals with sensitive or compromised skin barriers.
Â
One of the main reasons soap is not as harmful as skincare products containing sodium hydroxide lies in our rinsing habits. We use soap for cleansing purposes and promptly wash it away, preventing its prolonged interaction with the skin. On the other hand, face creams and serums are meant to be left on the skin to allow their active ingredients to be absorbed effectively. Unfortunately, this means that the damaging effects of sodium hydroxide can have a more significant impact when incorporated into leave-on products.
Â
Beyond the adverse effects on the skin, emerging research has raised concerns about the connection between sodium hydroxide and more severe health issues. In particular, hair relaxers, which commonly contain high levels of sodium hydroxide, have been linked to the development of fibroids and certain cancers. Although further studies are required to establish conclusive evidence, it highlights the potential risks associated with long-term exposure to this powerful chemical.
Â
In conclusion, while sodium hydroxide plays a crucial role in soap-making and certain hair treatments, it should be used with caution in leave-on skincare products. Its corrosive nature can lead to skin irritation and damage when left on the skin for extended periods. As consumers, it is essential to read product labels diligently and opt for safer alternatives when choosing skincare items. Staying informed and mindful of the ingredients in our beauty products empowers us to make healthier choices and protect our skin from potential harm.
