What happens if the stratum corneum is thin?

A thin stratum corneum may lead to a series of skin problems. 1) The skin becomes sensitive and fragile, easily affected by external stimuli such as temperature changes or cosmetic ingredients, which may trigger discomfort or allergic reactions. 2) A thin stratum corneum compromises the skin's natural protective barrier, accelerating water loss and leading to dryness, tightness, and dullness. 3) It may also increase the skin's susceptibility to bacteria and viruses, making infections more likely. Therefore, maintaining a healthy stratum corneum is crucial. Avoid excessive cleansing and exfoliation, use gentle skincare products, and pay attention to sun protection and moisturization. If necessary, seek help from a dermatologist for proper repair and care.
