The provided reviews do not explicitly mention the Rice bran clear serum's effect on strengthening the skin barrier. However, several reviews highlight its hydrating properties and gentle formula, which can contribute to overall skin health. Strengthening the skin barrier is often associated with products that provide deep hydration and contain soothing ingredients.

While the reviews focus more on hydration and texture, it's possible that the serum's hydrating effects could indirectly support skin barrier function. For a definitive answer on whether it strengthens the skin barrier, more specific information or studies would be needed.
