Alkaline

Description

Alkaline substances play a significant role in skincare formulations, primarily due to their ability to influence the pH balance of products and the skin itself. With a pH greater than 7, alkaline ingredients can counteract acidity and are often utilized in cleansers, exfoliants, and certain treatment products. Common alkaline ingredients in skincare include sodium hydroxide, potassium hydroxide, and various carbonates.

These ingredients can effectively remove excess oils and debris from the skin's surface, making them particularly useful in formulations for oily or acne-prone skin types. However, their use requires careful consideration, as excessive alkalinity can disrupt the skin's natural protective barrier, leading to dryness, irritation, or increased sensitivity. When properly formulated, alkaline ingredients can contribute to the efficacy of products like soaps, facial cleansers, and chemical peels.

It's crucial to note that the skin's natural pH is slightly acidic, typically ranging from 4.5 to 6.5. Therefore, prolonged use of highly alkaline products may potentially alter the skin's microbiome and compromise its ability to defend against harmful bacteria and environmental stressors. Skincare formulators must balance alkaline ingredients with acidic components to create products that maintain or restore the skin's optimal pH level.
