New Delhi: Whether it is a daily face cream or a heavy winter moisturiser, alcohol is a surprisingly common ingredient in many skincare products. But why is it added, and does it secretly damage the skin? Dermatology experts suggest that the impact of alcohol entirely depends on its type, concentration, the product’s overall formulation, and the user’s specific skin type. In short, not all alcohols are harmful to your skin.
According to skincare experts, alcohol serves multiple functional purposes in cosmetic chemistry. Dr. Chaitra Anand, Chief Formulator and Co-founder of SkinQ, explained that certain types of alcohol help active ingredients dissolve better in the cream. They also improve the texture, making it easier for the product to spread evenly across the skin. Furthermore, alcohol acts as a quick-drying agent and can sometimes serve as a preservative, maintaining the stability and shelf life of the formulation.
Simple alcohols, like ethanol, evaporate rapidly. This is why some skincare products feel lightweight and non-sticky immediately after application. Mithun Majumdar, an expert from 750AD Healthcare Pvt Ltd, pointed out that alcohol in skincare does not merely dry out the skin; it offers several benefits, including protection against microbial growth.
However, moderation is key. The outermost layer of our skin, the stratum corneum, acts as a protective barrier comprising dead cells, ceramides, cholesterol, and free fatty acids. This barrier retains moisture and keeps external irritants out. While ethanol helps dissolve ingredients and aids in deep penetration, an excessively high concentration can weaken this protective shield.
It is also crucial to differentiate between simple alcohols (like ethanol) and fatty alcohols. Fatty alcohols, such as cetyl, stearyl, and cetearyl alcohol, are entirely different in their chemical structure. Dr. Anand noted that these are typically used as moisturisers and emulsifiers. They help keep the skin soft, improve the product’s consistency, and bind the oil and water components together, without causing the dryness associated with simple alcohols.
Experts warn that certain alcohols, especially when used in high quantities, can strip the skin of its natural lipids, leading to dryness or irritation. This is particularly true for individuals with sensitive skin, eczema, or a compromised skin barrier. Therefore, when choosing a moisturiser, it is essential to check the ingredient list and understand which type of alcohol has been used to ensure it suits your specific skin needs.
