Will applying face masks too often make the skin's stratum corneum thinner?

Using face masks frequently does not necessarily directly lead to thinning of the stratum corneum, but overuse or improper use may negatively affect this skin layer. The stratum corneum is the outermost barrier of the skin, serving to protect against moisture loss and external irritants. Excessive use of face masks—especially those containing irritating ingredients—or leaving masks on for too long may disrupt the normal metabolism and renewal process of the stratum corneum, potentially leading to its thinning or damage. Additionally, certain masks may contain excessive chemical ingredients or fragrances that could cause skin irritation or allergic reactions, further compromising the health of the stratum corneum. Therefore, when using face masks, it's important to choose products suitable for your skin type and needs, follow proper usage instructions, and avoid overuse or incorrect application in order to maintain the health and integrity of the stratum corneum.
