What is the recommended pH level for skin care products?

The recommended pH level for skin care products is typically between 4.5 and 5.5, which aligns with the natural pH of healthy skin. This slightly acidic range helps to maintain the skin’s natural barrier, known as the acid mantle, which protects against harmful bacteria, pollutants, and dehydration.

Products formulated within this pH range support the optimal functioning of enzymes that help with skin regeneration and hydration and minimize irritation that can occur from products that are too alkaline or too acidic. By choosing skin care products around this pH, consumers can help ensure they are nourishing and protecting their skin effectively.

Options that suggest a higher pH, such as 7.0 to 8.0 or 5.5 to 6.5, can potentially disrupt the skin’s natural balance, leading to dryness and increased sensitivity. Conversely, a very low pH, like 3.0 to 4.0, while suitable for some specific purposes, may be too harsh for regular use on most skin types, especially if used frequently. Thus, the 4.5 to 5.5 range is ideal for general skin care products.
